Abstract:
The objectives of our study were to propose a growth curve and to develop a mathematical model to describe the body weight of pullet experiencing severe heat stress (42°C). Poultry producers who raise their own replacement pullets can control their pullet’s growth, condition and development. Many of the problems which occur during the early part of lay can be traced back to insufficient or improper type of body weight attained during the various stages of the growing period. In order to avoid these problems, the body weight of pullets must be controlled. Rearing conditions for pullets vary depending on environmental pressures and can affect growth rate. Without the basic knowledge of the flock grow-out, it is virtually impossible to understand and possibly solve problems which may later occur during the laying period. It must be kept in mind that once egg production begins, it is too late to solve problems resulting from growing period. The two most important criteria of pullet quality are uniformity within the flock and proper body weight at a specific age. Almost anything that adversely affects a pullet will usually be reflected in lower body weights and poorer flock uniformity. High ambient temperatures can be devastating to commercial pullet growth rate; coupled with high humidity they can have an even more harmful effect on proper and recommended body weight. Heat stress interferes with the poultry comfort and suppresses performance efficiency. In order to verify the effect of heat stress on pullet growth rate, many curve modelled, fitted and verified to proposed best one.

Abstract:
Although Canada is one of the first to provide guidelines on pullet rearing in a new Code of Practice which came into effect in March 2017, little information is available about the housing and management of pullets on Canadian farms. We surveyed 99 pullet farmers and received useable responses from 33 pullet farmers (33.3% response rate) who took part in the Start Clean-Stay Clean™ program through their provincial egg boards across Canada during October–December 2017 as part of a larger study. Most flocks were housed in conventional cage systems (42.4%), followed by single-tier (33.3%) and multi-tier systems (24.2%). Flocks ranged from 1–19 weeks of age (average: 10.5 weeks of age) and were white- (58.1%) or brown-feathered (41.9%). In general, non-cage farmers met the new requirements set out in the Code of Practice for space, perches and litter provision during pullet rearing during this transitional period. Conventional caged flocks did not have opportunities for perching and foraging, but developing new methods to provide pullets with opportunities to perch and forage will become more important as the laying hen housing system transition from conventional cages to furnished cage and non-cage housing systems in Canada progresses. Additionally, clear litter management recommendations for farmers to ensure good litter quality are needed for non-cage housing systems.

Abstract:
In trial 1, eggs from young (28 wk) and old (65 wk) leghorn breeders were categorized into groups with mean weights of 54, 59 or 64 g. Female chicks were cage-reared to 18 wk of age; three rearing treatments involved five replicate cages of nine pullets from each egg size category, while treatment 4 involved a mixed population. The largest eggs contained most yolk fat and protein and albumen protein (P < 0.05). Egg size had no effect on male chick composition (P < 0.05). There was no overall effect of egg size or breeder age on feed intake of pullets, although up to 8 wk of age, pullets from small eggs were consistently smaller than those from large eggs. Egg size and breeder flock age had no effect on pullet weight at 18 wk. Pullets reared as a combination group of small:medium:large (3:3:3, treatment 4) showed a significant (P < 0.05) egg size effect on pullet weight at 18 wk of age. In a second trial, eggs were collected from a 45-wk-old flock of commercial leghorn breeders. Eggs were set according to weight, with mean egg weights of 56.4, 61.1 or 66.8 g. Rearing treatments related to the three egg size categories were represented by 10 replicate groups of nine birds each. A fourth treatment involved 26 groups of three chicks from each of the egg weight treatments. Breeder egg size had a significant effect on pullet weight at 126 d. With this differential maintained through the first 12 wk of lay. Breeder egg size had no effect on egg production (P > 0.05), although mean commercial egg weight and feed intake (P < 0.01) were directly proportional to hatching egg size (P < 0.01). It is concluded that hatching egg size can have a significant effect on life-cycle performance of leghorns, and as such, there may be scope for differential management of pullets hatched from different sizes of egg.

Abstract:
Commercial layer-type, pullet, cockerel, and broiler chicken flocks infected with highly pathogenic avian influenza (HPAI) H5N1 in Nigeria between 2006 and 2008 were investigated for morbidity, mortality, and pathology. Of the one hundred and fifty-three (153) farms confirmed with HPAI infection, one hundred and twenty-seven (127) were layer-type farms, nine (9) were pullet and broiler farms each, and eight (8) were cockerel rearing farms. This study revealed the morbidity and mortality of a total of 939,620 commercial layer chickens, 16,421 pullets, 3,109 cockerels, and 6,433 broilers. Mortality rates were 11.11% in commercial layers, 26.84% in pullets, 45.51% in cockerels, and 73.92% in broilers in a total of eighteen (18) states and the Federal Capital Territory, Abuja. A total of 316 carcasses were examined of which 248 were commercial layer, 25 were pullet, 14 were cockerel, and 29 were broiler. Main clinical and pathologic findings were observed in the nervous, circulatory, respiratory, integumentary, musculoskeletal, hemopoietic, gastrointestinal, and reproductive systems and, occasionally, lesions were generally nonspecific and multisystemic. Lesions occurred more frequently, severely, and in most of the carcasses examined, irrespective of chicken type.

Abstract:
After hatching, pullets are transported to brooding area and vaccinated. One day old chicks have not already developed thermoregulation ability; thus, brooding temperature variations may affect pullet quality leading to broiler meat production losses. This research aimed to calculate sensible heat loss in one day old pullets in hatching area and vaccination room. Ten one day old pullets were randomly selected from hatching area of a commercial hatchery. Infrared images were used to calculate bird surface temperature. Exposure areas for the two conditions were quantified, and both air temperature and wind speed was recorded. Total sensible heat loss was calculated as heat loss by radiation plus heat loss by convection. It was found that heat transfer occurs in different ways at different bird body parts. Total heat loss found for hatching baskets was equivalent to 0.81 J s-1 while for vaccination room was 1.16 J s-1. Pullet nutrition is based on energy loss from brooding to farm, and the overall pullet heat loss from hatchery to farm accepted is 13.95 J s-1. Thus, "starter feed" has relevant excess of energy input. These findings indicate that less energy can be used in initial feed, once heat loss is lower than assumed nowadays. Improved knowledge on these conditions may enhance broiler farm feeding strategies and economics during first rearing week.

Abstract:
In Australia, free-range pullets are typically reared indoors, which may hinder later adjustment to outdoor access. Rearing enrichments could optimise pullet development. Hy-Line Brown® chicks (n = 1700) were reared indoors across 16 weeks with 3 enrichment treatments: (1) a standard control; (2) novel objects (novelty) provided weekly or (3) perching structures (structural) provided. All pullets were weighed at 5, 8, 12, and 16 weeks old. Pullets (n = 87) were tested in a novel arena at 9 weeks and manual restraint (n = 90) at 16 weeks. At 15 weeks, lymphoid organs were extracted and weighed from 90 pullets. Pullets were transferred to the free-range facility at 16 weeks and housed in 9 identical pens within rearing treatments. Hens perching were counted via video recordings across the first week. The structural pullets had the highest relative adrenal weights (p = 0.03) but differences may not have been biologically relevant. Structural hens perched less than the novelty hens in the layer facility (p = 0.02). There were no other consistent rearing treatment differences. The rearing environments had minimal effects on pullet behaviour and welfare, but data from the adult hens did show some longer-term welfare impacts.

Abstract:
Chickens under appropriate light–dark programs can develop diurnal rhythms. However, actual needs of layer pullets for the light and dark environments are not fully understood. This study was to investigate the diurnal rhythms of pullets in the light (30 lx) and dim (<1 lx) environments. The preferences of pullets on the light and dim environments were examined. The testing system contained four identical compartments (0.96 m length × 1.20 m width × 2.00 m height for each). A light-emitting diode tube, a camera, and weighing sensors were installed in each compartment. Four groups of eight Chinese domestic layer pullets, Jingfen, were used at the weeks 15–18. Choices of environments and feeding behaviors were monitored by weighing sensors, and activity was measured by digital image processing. The results show that pullets spent on average 35.5 ± 2.2 min under the light and 24.5 ± 2.1 min under the dim in each hour. Human inspection can stimulate bird feeding and activity. Overall, pullets behaved more actively under the light than under the dim environment. Pullets stayed in the light and dim environments throughout each hour of a day, which may suggest that lighting environments with free choices in a pullet house might better serve for pullet preference.

Abstract:
Two experiments were conducted with golden Hubbard pullet chicks to investigate the replacement effects of locally prepared fish silage for imported fish meal in pullet and layers' rations. Acidic and neutral fish silage preparations concentrated with either maize or cassava plus groundnut meal and wheat offals, were fed as a substitute for fish meal. Results with pullets showed good feed consumption for all dietary treatments but feed efficiency was decreased (P<0.05) for neutral cassava, acidic maize and acidic cassava fish silage treatments. Pullet mortality was between 0.18 and 4.17%, being significantly (P<0.05) highest in the acidic fish silage diets. Lipid retention, metabolizable energy (ME) and efficiency of energy utilization (ME%) were similar across all treatments except for neutral maize fish silage, in which ME was slightly high and lipid retention low. Egg production and egg size significantly (P<0.05) decreased among groups of birds fed acidic maize acidic cassava and neutral cassava fish silage diets. Similarly, the efficiency of feed conversion to eggs decreased (P<0.05) in all fish silage substituted diets.

Abstract:
The study was conducted to determine the effect of egg size on post-hatching performance of pullet chicks obtained from Dominant Black (DB) and Yaffa Brown (YB) strains of pullet. A total of eight hundred and ten hatching pullet eggs (405 eggs per strain) were grouped into three egg sizes (small, medium and large) per strain resulting in six treatment groups which were replicated three times with forty-five eggs per replicate. Post-hatching performance of one hundred and sixty two pullets from both strains was monitored till first egg was laid. Feed and water were supplied ad libitum throughout the period. Three eggs per replicate were used to determine both internal and external egg qualities. Data obtained were subjected to analysis of variance in a 2 x 3 factorial experimental design. The results showed that average body weight, feed and protein intake of the birds during starter phase of pullet chicks significantly (p0.05). Age at first lay, weight of bird at first lay and egg quality parameters were not affected (p>0.05) by egg size and strain. The egg size also increased (p0.05) influence on all the parameters measured throughout the study. It was concluded that egg size could only be beneficial if the target is to sell chicks at the end of growing phase. However, setting of different egg sizes could be encouraged since the effect at maturity (laying) is not significant.

Abstract:
The effect of bitter leaf (Venonia amygdalina) and water leaf (Talinum triangulare) extracts on blood vitamins and minerals composition of pullet birds were investigated. A total of 456 day-old Isa brown pullet chicks were allotted to four dietary treatments in six replicates in a completely randomized design experiment. Aqueous extracts of bitter leaf and water leaf were used as test dietary treatments for the birds. In treatment 1, a commercial multivitamin (vitalyte) was given in water (1g/L) to the birds to serve as the control. In treatments 2 and 3 aqueous extracts of bitter leaf and waterleaf were given at 100ml/L of water, while in treatment 4 mixed bitter leaf and water leaf aqueous extract (50% each in composition) was given. On the last day of the feeding trial, blood samples were collected from the birds for vitamins and minerals analysis. The observed results showed that dietary treatments significantly affected the blood serum parameters. Vitamin A was significantly higher (P < 0.05) in the vitalyte birds. The values ranged from 0.27iu in the bitter leaf birds to 0.37iu in the vitalyte. Vitamin C was more abundant (1.84iu) in the bitter leaf treated pullets and was significantly reduced (1.21iu) in the vitalyte. Vitamin D was significantly (P < 0.05) higher (0.35 iu) in the water leaf as well as vitamin E (10.14iu) while they were highly reduced considerably in the vitalyte administered birds, 0.16 and 4.83iu respectively. On mineral composition, while bitter leaf was the highest Ca (14.24mg/dl) source, K (5.46 mmol/L) and Mg (2.78mg/dl) were highly increased in the water leaf administered birds. Pullets on the control vitalyte had higher Na (132.75 mmol/L) and Fe (1.42g/dl). It can however be concluded that bitter leaf and water leaf as used in this study are potential sources of some vitamins and minerals in pullet chick nutrition.

Abstract:
Avian respiratory disease causes significant economic losses in commercial poultry. Because of the need to protect long-lived poultry against respiratory tract pathogens from an early age, vaccination programs for pullets typically involve serial administration of a variety of vaccines, including infectious bronchitis virus (IBV), Newcastle disease virus (NDV), and infectious laryngotracheitis virus (ILTV). Often the interval between vaccinations is only a matter of weeks, yet it is unknown whether the development of immunity and protection against challenge when vaccines are given in short succession occurs in these birds, something known as viral interference. Our objective was to determine whether serially administered, live attenuated vaccines against IBV, NDV, and ILTV influence the development and longevity of immunity and protection against challenge in long-lived birds. Based on a typical pullet vaccination program, specific-pathogen-free white leghorns were administered multiple live attenuated vaccines against IBV, NDV, and ILTV until 16 weeks of age (WOA), after which certain groups were challenged with IBV, NDV, or ILTV at 20, 24, 28, 32, and 36 WOA. Five days post-challenge, viral load, clinical signs, ciliostasis, tracheal histopathology, and antibody titers in serum and tears were evaluated. We demonstrate that pullets serially administered live attenuated vaccines against IBV, NDV, and ILTV were protected against homologous challenge with IBV, NDV, or ILTV for at least 36 weeks, and conclude that the interval between vaccinations used in this study (at least 2 weeks) did not interfere with protection. This information is important because it shows that a typical pullet vaccination program consisting of serially administered live attenuated vaccines against multiple respiratory pathogens can result in the development of protective immunity against each disease agent.

Abstract:
The present study examined the comparative performance between Bovans Nera and other commercial pullet strains in Nigeria. This study was carried out in the pullet house at the Teaching and Research Farm of the University of Ibadan, Ibadan, Nigeria, from January to April, 2002. The experiment was carried out to compare the growth performance and profitability of Bovans Nera with three other commercial pullet strains, Bovans Godline, Lohmann White and Lohmann Tradition. All data collected were subjected to the analysis of variance using the SAS General Linear Model procedure. Differences between treatment means were separated using Duncans New Multiple Range Test. Profitability was assessed using net returns by subtracting costs (rearing pullet, feed and packaging excluding overheads and labour) from income (from egg sales and spent birds). The results showed that Bovans Nera was better in feed conversion ratio, feed efficiency (a greater weight gain per unit feed intake) and attained a greater weight and a better market value than the other pullet strains. There was a higher production cost for Bovans Nera when compared with other strains. However, Bovans Nera will give more returns on investment even when their eggs are translated to monetary terms. These differences can be attributed to variation in the genetic constitution of individual strains.

Abstract:
An eight weeks restricted feeding trial was conducted to investigate the effect of restricted feeding and strain on the growth performance and haematological parameters of two strains of pullet chicks. Five hundred and forty chicks comprising of Isa Brown (270) and Bovans Nera (270) strains were assigned to six treatments arranged in a 2 x 3 factorial arrangement of Isa Brown and Bovans Nera on ad libitum (R ), skip-a-day (R ) and skip-2-days (R ) restrictions per week, respectively. Final live weight and weight gain of pullet chicks reduced (P < 0.05) with increasing level of feed restriction. Chicks on ad libitum showed improved (P<0.05) final live weight and weight gain. Results showed significant (p<0.05) reduction in feed intake and body weight of chicks due to restricted feeding. The birds maintained on R feed restriction group recorded the highest significant (p<0.05) values of final body weight (544.57g), feed intake per day (33.70g/day) and daily weight gain (9.82g/day). R birds recorded significantly (p<0.05) higher values of final weight, feed intake and weight gain when compared with R birds with final body weight of 480.84g, daily feed intake of 28.42g/day and daily weight gain of 8.48g. Furthermore, Bovans Nera pullet chicks recorded significantly higher (p<0.05) final weight and daily weight gain when compared with the Isa Brown birds of same age. The R pullets had significantly higher (p<0.05) white blood cells when compared with the R and R birds. Heterophil/lymphocyte ratio (0.52) was significantly (p<0.05) lower with the Isa brown birds.

<p>The research was conducted to analyze the effect of seaweed Gracilaria edulis in the diets on the performance of pullet. One hundred and twenty six Lohmann Brown Strain pullets of 14 weeks old were divided into seven seaweed diet treatments. The treatment diets were R0, R1, R2, R3, R4, R5, and R6 contentaining 0.00; 2.50; 5.00; 7.50; 10.00; 12.50 and 15.00 of seaweed, there was three replications, six pullets of each. The collected data were feed consumption, weights and ages of sexual maturity, feed conversion ratio, weight of egg and Iodine content in the egg. The collected data were analyzed by analysis of variance of one way classification, followed by Duncan’s New Multiple Range Test (DMRT). The results showed that the treatments had not significant differences on feed consumption, body weight at sexual matuarity, feed conversion ratio, but significans (P&lt;0.05) on ages at sexual matuarity and egg yolk color (P&lt;0.01). Feed consumption were 80.94 g/chicken/day; 81.02 g/chicken/day; 80.95 g/chicken/day; 81.43 g/chicken/day; 81.69 g/chicken/day; 82.25 g/chicken/day and 82.72 g/chicken/day, body weight at sexual matuarity<br />1898.56 g; 1977.78 g; 1947.78 g; 1947.78 g; 1949.78 g; 1981.67 g; 1949.44 g, FCR 5.78; 5.35; 5.45; 5.08; 5.57; 5.86 and 6.25, egg yolk color 10.23; 11.27; 11. 83; 12.11; 12.44; 12.44 and 12.83 for R0, R1, R2, R3, R4, R5, and R6 <br />respectively. Egg weights were 51.25 g; 54.50 g; 50.89 g; 51.66 g; 51.36 g; 51.36 g and 50.83 g, for R0, R1, R2, R3, R4, R5, and R6 repectively. There had not significant differences on content of egg yolk iodine were 0.47 ppm; 0.48<br />ppm; 0.50 ppm; 0.52 ppm; 0.55 ppm; 0.56 ppm and 0.60 ppm. It was concluded that the use of seaweed Gracilaria edulis until 15.00% in the diet did not decrease the performance of pullet phase and increased egg yolk color, also did not increase iodine in the yolk.</p><p>(Key words: Seaweed Gracilaria edulis, Diets, Chicken’s work, Pullet phase)<br /><br /></p>

Abstract:
Enrichment during the indoor rearing of pullets destined for free-range systems may optimize pullet development including increasing motivated natural behaviors (termed ‘positive behaviors’) including foraging, dust bathing and chick play. Hy-Line Brown® chicks (n = 1700) were floor-reared indoors across 16 weeks with three enrichment treatments (n = 3 pens/treatment): (1) standard control, (2) weekly novel objects—‘novelty’, (3) perching/navigation structures—‘structural’. At 16 weeks, pullets (n = 1386) were transferred to nine identical pens within rearing treatments with outdoor range access from 25 to 65 weeks. Video cameras recorded the pullet pens, adult indoor pens, and outside range. During rearing, observations of play behavior (running, frolicking, wing-flapping, sparring) in chicks at 2, 4 and 6 weeks (total of 432 thirty-second scans: 16 observations × 3 days × 9 pens) showed no overall effect of rearing treatment (p = 0.16). At 11 and 14 weeks only the ‘novelty’ hens were observed to increase their foraging across age (p = 0.009; dust bathing: p = 0.40) (total of 612 thirty-second scans per behavior: 17 observations × 2 days × 2 age points × 9 pens). Observations of adult hens at 26, 31, 41, 50, 60 and 64 weeks showed that the structural hens exhibited overall more dust bathing and foraging than the control hens (both p < 0.04) but both novelty and/or structural hens showed small increases depending on the behavior and location (total of 4104 scans per behavior: 17 observations × 2 days × 6 age points × 9 pens × 2 locations = 3672 + an additional 432 observations following daylight saving). Across age, adult hens differed in the degree of dust bathing performed inside or outside (both p ≤ 0.001) and foraging outside (p < 0.001) but not inside (p = 0.15). For litter-reared pullets, additional enrichments may result in some long-term increases in positive behaviors.

Abstract:
sudden mortality which lasted for seven days with the peak on the third day, was investigated in vaccinated 3-week old pullet chicks. Signs of depression, ruffled feathers, sneezing, huddling together and pasted vents with about 50% morbidity were observed. While chicks were off feed. Vaccination history against Marek’s and Newcastle diseases was reportedly up to date. The first dose of Infectious Bursal Disease (IBD) vaccination was done 12 days before the onset of the outbreak preparatory to the second dose. Detailed post mortem examinations showed multifocal petechial to ecchymotic haemorrhages on the breast and thigh muscles with swollen, oedematous and haemorrhagic bursa of Fabricius in affected chicks. The bursa of Fabricius showed diffuse lymphoid depletion with multifocal vacuolations and eosinophilic cystic follicles. Similar diffuse lymphoid depletion and cytoplasmic vacuolation with fibrinous exudation were also present in then spleen, Serological analysis revealed 88.23% IBD antibody positive sera in affected pullets 16 days after cessation of mortality. A diagnosis of Infectious Bursal Disease outbreak was made based on the observed pathological presentations along with the clinical signs, typical spiked mortality pattern, and serological titre. These findings highlighted the need for continuous pathological investigations as a ready diagnostic tool in vaccinated and unvaccinated pullet chicks in Nigeria where Infectious bursal disease has become endemic.

Abstract:
Abstract Local Indonesian chicken from Bangka Belitung is known as Merawang. This chicken has dual purposes as a meat and egg producer. The objective of this study was to determine the repeatability and most probable producing ability (MPPA) of Merawang chicken’s egg weight and one-day-old chick (DOC) weight. 72 pullet Merawang chickens were raised in single bird cages and their egg weight was checked at 36-38 and 56-58 weeks. The DOC was weighed after the eggs were hatched. The rptR package and the restricted maximum likelihood (REML) method were utilized to estimate the repeatability. At 36-38 and 56-58 weeks, the average egg weight was 46.435.44 and 52.146.15, respectively. Meanwhile, the average DOC weight at 36-38 and 56-58 weeks were 31.92±4.54 and 35.40±4.36, respectively. The result showed that at 36-38 and 56-58 weeks, the repeatability of egg weight was 0.77±0.05 and 0.69±0.05, whereas the DOC weight was 0.84±0.04 and 0.64±0.07. The average MPPA ranges based on egg and DOC weights were 46.51-52.23 and 31.97-35.52, respectively. The pullets with MPPA above the average were 38.46%-50.72% (egg weight) and 48.94%-56% (DOC weight). The results from this study can be used for selecting the Merawang pullet.

Abstract:
Leghorn pullets were reared on one of four dietary programs formulated to (1) conventional least-cost, (2) least-cost to amino acid requirements with no specification for crude protein, (3) as (2) with cost of protein feedstuffs increased 40% and (4) corn-soybean meal. All diets contained 18% and 15% CP, or equivalents, for 0–6 and 6–18 wk, respectively. Diets were offered ad-libitum to 14 replicate groups of 10 caged pullets. Pullets fed the conventional least-cost and corn-soybean diets were heavier (P < 0.05) at 6 wk of age than pullets reared on either of the two diets formulated to amino acid specifications. At 12 and 18 wk of age, conventionally fed birds were heavier than pullets fed amino-acid-based diets, while all groups were heavier than birds fed the corn-soybean diet. To 28 wk of age, pullets reared on amino-acid-based diets under conditions of elevated protein prices, produced more eggs (P < 0.05) relative to pullets reared on treatments 2 and 4. Results confirmed that pullets can be reared on diets formulated without crude protein specifications, and that substantial use of synthetic amino acids is not detrimental to growth or early reproductive performance.

Abstract:
Abstract. Light plays an important role in poultry development, production performance, health, and well-being. Light technology continues to advance, and accordingly new light products are finding applications in poultry operations. However, research concerning responses of young and adult laying hens to light sources is relatively lacking. This study assessed the choice between a Dim-to-Red poultry-specific light-emitting diode (LED) light (PS-LED, correlated color temperature or CCT = 2000K) and a warm-white fluorescent light (FL, CCT = 2700K) by pullets and laying hens (W-36 breed) via preference test. Birds with different prior lighting experiences were evaluated for their light choice, including (1) pullets (14 to 16 weeks of age or WOA) reared under incandescent light (designated as PINC), (2) layers (44 to 50 WOA) under PS-LED (LLED) throughout the pullet and laying phases, and (3) layers under FL (LFL) throughout the pullet and laying phases. Each bird category consisted of 12 replicates, three birds per replicate. Each replicate involved a 6-day preference test, during which the birds could move freely between two interconnected compartments that contained PS-LED and FL, respectively. Time spent and feed intake by the birds under each light were measured and then analyzed with generalized linear mixed models. Results showed that regardless of prior lighting experience, birds in all cases showed stronger choice for FL (p = 0.001 to 0.030), as evidenced by higher proportions of time spent under it. Specifically, the proportion of time spent (mean ±SEM) under FL versus PS-LED was 58.0% ±2.9% vs. 42.0% ±2.9% for PINC, 53.7% ±1.6% vs. 46.3% ±1.6% for LLED, and 54.2% ±1.2% vs. 45.8% ±1.2% for LFL. However, the proportions of daily feed intake occurring under FL and PS-LED were comparable in all cases (p = 0.419 to 0.749). The study thus reveals that prior lighting experience of the pullets or layers did not affect their choice of FL versus PS-LED. While the birds exhibited a somewhat stronger choice for FL, this tendency did not translate into differences in the proportion of feed use under each light type.

Abstract:
An experiment was conducted at the Animal Science Farm, Tuntungin, Putho of the Institute of Animal Science, University of the Philippines, Los Banos, College, Laguna, Philippines, during 2001-2002. Ninety 24-weeks old individually caged pullets were used in this study. Five treatments were randomly assigned to the 90 pullets following a completely randomized design. Each treatment was replicated 18 times with one pullet each. The dietary treatments were: basal diet (18% CP and 2800 kcal /kg, ME) reduced (red). CP diet (17% CP and 2800 kcal /kg, ME), red CP diet + 0.05% protease, red CP diet + 0.075% protease and red CP diet + 0.10% protease. Apparent digestibility of each nutrient in relation to egg production, egg weight, feed consumption, feed efficiency, body weight gain, shell thickness and yolk pigmentation, mortality, and income over feed cost were calculated All the data collected were subjected to statistical analysis using the general linear model (GLM) procedure of the SAS Institute (1988). One percent reduction of crude protein of diet of pullet significantly decreased the digestibility of all nutrients. Feed efficiency was significantly improved with 0.1% protease, while eggshell thickness was significantly improved with 0.075% protease supplementation of diets. Income over feed cost increased with dietary supplementation of protease. Increased level of protease supplementation of reduced CP diets consistently improved the digestibility of nutrients, overall average egg production and decreased feed consumption. Egg weight and feed efficiency were slightly improved with 0.075% and 0.1% protease supplementation of diet. Eggshell thickness was significantly improved with 0.075% protease Yolk color was not significantly influenced by increased protease supplementation of the diet. Income over feed cost was consistently increased with protease supplementation. It was concluded and recommended that crude protein of layer diets could be reduced by 1% provided that they are supplemented with protease, optimum level of inclusion of protease is 0.1% for layers and enzyme activity need to be accurately determined before it is used.

Abstract:
The effects of light intensity (L) are not well studied in pullets. Our research objective was to study the effect of L on navigational success, behavior, and welfare of two pullet strains (S). In two repeated trials, a 3 × 2 × 4 factorial arrangement tested three L (10, 30, 50 lux) and two S (Lohmann Brown-Lite (LB), LSL-Lite (LW)) at four ages. One thousand eight hundred pullets/S (0–16 wk) were randomly assigned to floor pens within light-tight rooms (three pens/S/room, four rooms/L) containing four parallel perches and a ramp. Data collection included jumping frequency and success (24h continuous sampling), novel object tests (fear), heterophil to lymphocyte (H/L) ratios (stress), and behavior (instantaneous scan sampling) during photoperiods. L did not affect injurious behavior, fear, or H/L. Pullets reared at 50 lux spent more time preening than at 10 lux. Pullets reared at 10 lux spent more time wall pecking than at 50 lux. Time spent standing and preening and total number and accuracy of jumping increased with age. Pullets reared at 30 lux had higher jumping frequency than at 10 lux; accuracy was not affected. LW jumped more than LB, but with similar success. LB spent more time exploring and scored higher in the fear and stress assessments, suggesting S differences.

Abstract:
The study evaluated the effect of 24-hour fermentation of sweet orange fruit (Citrus sinensis) peel meal (24SOFPM) on its chemical composition and performance response to graded levels of peel meal in the diets of pullet chicks. Dry matter, crude protein and phosphorus level in 24SOFPM were close to that of maize. While limonene was higher in 24SOPFM, phytate was higher in maize than the 24SOPFM. One hundred and forty-four fourteen dayold Nera black pullet chicks were assigned to four experimental diets F0, F10, F20 and F30. SOPFM substituted maize in F0, F10, F20 and F30 respectively at 0, 10, 20 and 30%. The feeding trial lasted the remaining 6 weeks of the chicks’ phase. The study design was Completely Randomized Design. Daily feed intake was not significantly different (p>0.05). Average body weight gain was significantly different (p<0.05) and was depressed with no definite pattern in the SOPFM based diets. FCR was significantly different (p<0.05). Substitution of maize with SOFPM significantly (p<0.05) reduced feed cost/25kg, feed cost/bird and cost of production while decreasing efficiency of feed utilization for growth. Apparently, SOPFM might be a potential feedstuff which could substitute a proportion of maize in pullet chick’s diet when fermented for 24 hours.

The decision making at the time being will result several effects to the present condition. Therefore, before making a decision in investment, it is important to have an accurate analysis. This will minimize the possibility of failure. At the present condition, the management of CV. PELANGI FARM is having some problems in developing widening investment, that is in the laying pullet management sector because the company possesses adequate experience in this sector. The indicator used in the management of laying pullet farm is by using Nett Present Value (NPV) method, that is the acceptance of management counted from the 0 year and Payback Period Method (PPM) which is a parameter of investment payback. From the analysis, here researcher is able to suggest that with field of 4 ha the farm should have 18.000 poultry (chickens). The result of calculation using Net Present Value and payback Period Method whether by individual investment or loan in 5 years is: NPV with individual investment is Rp975,212,452; NPV with loan investment is Rp187,591,244.58; PPM with individual investment for 2 years, 2 months, 24 days; and PPM with loan investment for 4 years, 5 months, 20 days. From the result of analysis, it can be seen that in management of laying pullet farm with 18,000 chickens for 5 years whether by individual or loan investment, both of them are properly done.

Abstract:
Context Reducing the environmental impact of animal production is becoming a really hot topic, especially with raised concerns over excessive flows of nitrogen and phosphorus (P) to the environment. Aims The present study was conducted to determine the effects of phytase supplementation on growth, plasma biochemistry, bone mineralisation and P utilisation of pre-lay pullets fed varying levels of non-phytate P. Methods A total of 240 Lohmann pullet chicks were randomly allocated to one of six dietary treatments with eight replicate cages (5 birds per cage) per treatment. Six treatments included three phytase-free diets and three diets supplemented with 1000 U/kg phytase; the non-phytate P levels were 2.75–2.50–2.25, 3.75–3.50–3.25 and 4.75–4.50–4.25 g/kg in the former, and 1.75–1.50–1.25, 2.75–2.50–2.25 and 3.75–3.50–3.25 g/kg in the latter, for the age of 0–4, 4–8 and 8–16 weeks respectively. Key results No significant differences were found for growth performance, plasma biochemistry (calcium, P, alkaline phosphatase and albumin) and bone mineralisation among dietary treatments, but P retention (%) was different (P &lt; 0.001). Analysis of planned contrasts showed that phytase supplementation increased phytate P retention (P &lt; 0.001), and improving the utilisation of phytate P tended most efficiently under low P conditions. Total P retention rate was reduced slightly by phytase supplementation (P &lt; 0.05). Conclusions The results indicated that dietary non-phytate P level could possibly be reduced to 1.75, 1.50 and 1.25 g/kg for 0–4, 4–8 and 8–16 weeks of age respectively after phytase supplementation, without compromising pullet growth and performance during the pre-laying period. Implications The results of this study will contribute to decreasing P excretion by poultry and reducing the potential environmental impact with land application of manure.

A trial with 234 day-old Olympian Black pullet chicks was conducted for a duration of eight weeks to determine the optimum level of inclusion of Blood-Rumen content Mixture (BRC) in the diet of starter chicks. Chicks were fed ad-libitum starter diets containing 0, 5, 10, 15, 20% BRC and another 20% BRC diet containing no soya bean cake. Birds on all BRC-based diets had higher body weight gains and higher feed intakes than birds on the control diet. A progressive increase in feed: gain ratio was observed from 10%BRC to 20% BRC in the diets. The decline in the performance of chicks fed higher levels of BRC in the diet is suggested to be due to the high crude fiber content and possible amino acid imbalance of such diets. The results of this trial shows that starter pullets should not be fed more than 10% BRC.

Abstract:
A study was conducted to determine the chemical elements of the egg shell of exotic commercial pullets (Lohmann) in their first laying year. A total of 160 eggs from eight pullet were randomly selected at three-monthly intervals during the production year for the determination of chemical elements of the eggshell. The average concentrations of calcium, magnesium, phosphorus, nitrogen, potassium, sodium, zinc and iron were 90.36%, 0.87%, 0.90%, 3.85%, 0.51%, 0.10%, 0.002%, and 0.005% respectively. Most of the paired variates of the mineral elements showed significant (P < 0.01) inter-relationship as depicted by measures of correlation coefficients. There were no significant relationships between Ca and most mineral elements and on the other hand mg was significantly correlated with phosphorus N, K, and Zn. Correlation coefficients between P and Fe, N and Na, Zn or Fe and between Na and Zn were not significant.

Abstract:
Abstract The aim of the study was to determine the effect of genotype (breed/line) and spaying of pullets on body weight, estradiol level, carcass and meat quality. Subjects were Rhode Island Red (R-11), Yellowleg Partridge (Ż-33) and Sussex hens (S-66), 100 birds per line, which were divided into 2 groups, each having 50 pullets and 50 poulards. Spaying was performed at 10 wk of age, under local anesthesia by a veterinarian. The present study showed that blood estradiol levels in poulards were much lower than in pullets regardless of genotype. Poulards showed higher body weight and their carcasses higher lightness and yellowness. In the sensory evaluation, poulard breast meat was more tasty and leg meat also more juicy and tender compared to pullet meat. Among the three conserved breeds, Rhode Island Red (R-11) and Yellowleg Partridge (Ż-33) hens are the best starting material for poulard production. Their carcasses showed good muscling and intense yellowness desirable to the consumers. R-11 birds achieved highest body weight. Spaying of pullets had no significant effect on the profile of fatty acids, but greater and statistically significant differences in this regard were found between hen lines. Compared to S-66 birds, breast muscles of R-11 and Ż-33 birds contained more polyunsaturated fatty acids (PUFA). The breast and leg muscles of these birds had a lower content of saturated fatty acids (SFA ).

Abstract:
Abstract The influence of genotype (GTY) and 20-week body weight (PW20) on full-sexual maturity (FSM) productivity and hatching traits were investigated on two parent-stock layers in Ibadan, Nigeria. Data were obtained on twenty-two batches of BOVAN NERA (BN) and ISA BROWN layers (IB) each, between 2009-2019, from a breeding company in Ibadan. These were grouped based on strain and 20-week body weight. Experimental design was randomized block design (RBD). Data were subjected to general linear model (GLM) factorial and Tukey’s HSD, α=0.05, procedures of Statistical Analytical Systems® (SAS, 2002) software. BN had better pullet weight (P<0.05, ds=0.88), while IB possessed higher hen-day egg production, persistency of egg production and pullet day-old chicks hatched (P<0.05, ds=-0.86 to -1.44) at FSM. The 20-week low weight birds required intensive skillful management for compensatory weight-gain to FSM, while egg weight was higher in 20-week high weight class at full maturity (P<0.05, ds=0.06 to -1.19). Genotype by 20-week pullet-weight interaction revealed better genetics of BN genotype on compensatory growth between 20th week and FSM, and on PFM (P<0.05, ds=0.24 to 1.62). The better HDF and P80 (P<0.05, ds= -1.73, -1.61) of medium weight IB genotype signals its genetic ability for higher percent day-old chicks production (P>0.05, ds= -0.72 to -1.11).

Abstract:
Zusammenfassung Gegenstand und Ziel: Überprüft werden sollten Sicherheit und Unbedenklichkeit der Vakzination von Hühnern mit dem Impfautomaten „Pullet Vaccinator“, die vom Hersteller propagierte höhere Arbeitssicherheit und die Praktikabilität des Systems mit anschließender serologischer Kontrolle des Impferfolgs. Material und Methoden: Im ersten Versuchsabschnitt impfte je ein mit dem Spritzenverfahren geübter Tierarzt parallel mit der halbautomatischen Spritze und mit dem Automaten. Nach 1 Stunde wurden die Impfgeräte getauscht und für eine weitere Stunde geimpft. Der zweite Versuchsteil verlief analog zum ersten, doch führten hier im Impfen ungeübte Personen die Vakzination durch. Die Anzahl der geimpften Hennen wurde gezählt und von jeder der vier Impfgruppen (geübt/Spritze; geübt/Automat; ungeübt/Spritze; ungeübt/Automat) wurden 20 Tiere seziert, um die Auswirkungen der beiden Methoden zu vergleichen. Weiterhin erfolgte eine serologische Untersuchung zur Prüfung des Impferfolgs. Für die Evaluierung möglicher Spätfolgen der Vakzination wurden am letzten Termin der Blutentnahme weitere Hennen seziert. Ergebnisse: Der Impfautomat bietet eine höhere Arbeitssicherheit als die halbautomatische Spritze. Nach Spritzenapplikation lagen ausgeprägtere Impfschäden in der Muskulatur der Hühner vor. Geübte Personen impften mit der Spritze pro Stunde etwa doppelt so viele Tiere wie mit dem Automaten. Wurden die Impfungen von ungeübten Personen vorgenommen, war die Zahl geimpfter Tiere bei beiden Verfahren annähernd gleich. Die serologische Untersuchung ergab keine signifikanten Unterschiede zwischen den zwei Methoden in Bezug auf den Impferfolg. Schlussfolgerung und klinische Relevanz: Technisch ist der Impfautomat in einzelnen Punkten noch nicht ausgereift und sollte überarbeitet werden, um im praktischen Einsatz bestehen zu können.

Abstract:
The program of demonstration plot in Rempek Village, North Lombok Regency was expected to become a pioneer for laying chicken farm in the regency. Prior to development of planned facilities, site survey was conducted to find the purposed location and focus discussion group. The demonstration plot used house system with 6 x 20 m in width and length extending from east to west. The cage was built using mild construction iron poles and roofed using spandex. The roof was in a monitor-shape with half–open walls on the north and south sides. 550 cages were put iniside the house to keep 1100 pullets. For the pullet row put next to the walls, they were placed with the heads facing inwards; meanwhile for the pullets in the middle rows, they were placed back to back with each other. Every cage was equipped with a feeder and a nipple. During the rearing process, the pullets were fed 110 g/head/day of a mixture of commercial concentrate, corn, and bran with the ratio of 2:4:4, while drinking water was given ad libitum. The production process was normal with egg production peak reaching 92%. After 4 weeks of the peak production, North Lombok Regency was hit by several earthquake, causing the decrease of egg production for the feed was too procey for the production to continue
