Abstract:
The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm), chest width (mm) and body length (mm) with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

Abstract:
The effect of environmental conditions on hatching indices of poultry eggs is sufficiently important that new methods for their improvement are sought, among others through exposing the eggs during hatching to an artificially generated magnetic field of variable frequency. Hatching eggs in this study came from Pharaoh quail in the 4th month of laying. The flock was kept under optimum microclimate conditions and fed a complete feed mix containing 21% total protein and 11.7 MJ ME. The eggs (n = 150), after weighing, were divided into 3 groups equal in respect of numbers: control (I) and two experimental (II and III). The eggs of group II and III were exposed to the action of variable magnetic field of the same intensity but different times of application. The highest percentage of dead embryos during incubation in relation to fertilised eggs was found in control group (11.36%), while the smallest was from group II (4.17%). The highest value of hatching indices calculated in relation to fertilised eggs was found in group II (91.6%), while the smallest was in group III (83.7%) with 86.3% in control group. The results point to the possibility of increasing egg hatchability indices through the use of additional variable magnetic field. The chicks hatched from eggs exposed to the action of this experimental agent had similar body weight. The average weight of one-day-old chicks ranged from 7.82 g (group II) to 8.05 g (group III). In the last week of rearing, mean body weight in both sexes was similar and ranged from 168 (group I) to 172 g (group III) in males, and from 186 g (group I) to 199 g (group III) in females; these differences were not statistically significant. The females of group III reached sexual maturity at 41 days, this being one and three days (non-significantly) earlier than birds in group I and II.

Abstract:
In Russia, different quail breeds are widely grown and bred at specialized poultry farms and private farmsteads. In the Amur Region, only private farmsteads engage in this type of aviculture. The most common breeds are Pharaoh quail, Japanese quail, and Estonian quail. 100 eggs of the Estonian quail have been prepared for hatching in a specialized room at a private enterprise. The incubation has been carried out in the Rcom 20 MAX (RMX-20) machine at a temperature of + 37.2–380C and 55–60% humidity over 17–18 days. The egg hatchability amounted to 75%. In Russia, the birds receive balanced complete feeds of the following grades: P-K-5, P-K-2-1, P-K-6, Start, Super Start, RusQuail, Multigain and others. These feeds include different percentage mixtures of corn, oats, wheat, barley, meals and various types of flour (soy, fish, rice, etc.), yeast, chalk, phosphates, sodium chloride and other minerals. In the Amur Region, the balanced feed ration for poultry is produced by local companies “Amuragrocenter” and “Grinodir". These products have been used for feeding the chicks. The study of the Estonian quail bred at a private farmstead using the Amur feeds revealed some changes. According to the literary sources, the average weight of the Estonian breed is 180–200 g. The weight of the quails grown under the specified conditions was significantly higher — up to 200–260 g. In many regions, consumers prefer local products that they trust.

Abstract:
AbstractThe aim of this study was to evaluate the strength of vitelline membrane and its correlation with other morphological traits and the viscosity of egg yolk of different poultry species: goose, turkey, Muscovy duck, chicken, guinea fowl and Japanese quail. Vitelline membrane strength (VMS) was defined as work and force after the deformation of yolk at 6 mm. Bird species affected the VMS of egg yolk. The lowest strength was measured for the vitelline membrane of goose egg yolk. There were no apparent differences in the strength of vitelline membrane for ducks, guinea fowl, chickens and Japanese quail. In contrast, the vitelline membrane of turkey egg yolk appeared to be of the highest strength. Statistically significant positive correlations were observed between VMS and yolk index, while there was no correlation between the weight of the eggs and egg yolk. The work deformation of yolk was positively correlated with the viscosity of poultry egg yolk.

Abstract:
The aim of the study was to evaluate egg quality traits in three heavy Japanese quail populations created and reared in the Poultry Breeding Unit of the Trakia University – Bulgaria, marked as WG, GG and GL. In the experiments, 160 female birds from populations WG and GG, and 96 birds from population GL were tested up to the 6th production month. The main egg quality traits were controlled. The highest average egg weight was registered in WG group and the lowest in GL group, 14.04±0.32 g and 12.79±0.29 g respectively (p<0.05). The highest average Shape index was observed in group GG (78.31±0.53%), vs the lowest in WG quails (77.55±0.62%). Albumen proportion is almost 2/3 of egg mass, with average values from 57.14% in group WG tо 59.90% in group GG. Yolk proportion was about 30%, with smaller differences between the groups. The shell share from all tested groups comprised between 10.95 and 12.58% of egg weight. Average shell thickness was the greatest in eggs of WG quails (223.53±5.52 μm), and the lowest – in GG quails (216.91±6.83 μm). Egg quality traits were typical for the meat productive type of Japan quails.

Abstract:
Newcastle disease (ND), caused by virulent strains of Newcastle disease virus (NDV), is a devastating disease of poultry worldwide. The pathogenesis of ND in quail is poorly documented. To characterize the ability of virulent NDV strains to replicate and cause disease in quail, groups of 14 two-week-old Japanese quail ( Coturnix japonica) were experimentally inoculated with 108 EID50 (embryo infectious dose 50%) units of 1 of 4 virulent NDV strains: 2 isolated from quail ( N2, N23) and 2 from chickens ( Israel, Pakistan). At day 2 postinfection, noninfected quail (contact group) were added to each infection group to assess the efficacy of virus transmission. Tested NDV strains showed moderate pathogenicity, with highest mortality being 28% for the N2 strain and below 10% for the others. Two N2-inoculated birds showed neurological signs, such as head tremor and ataxia. Microscopic lesions were present in N2-, Israel-, and Pakistan-inoculated birds and consisted of nonsuppurative encephalitis. Contact birds showed no clinical signs or lesions. In both inoculated and contact birds, virus replication was moderate to minimal, respectively, as observed by immunohistochemistry in tissues and virus isolation from oropharyngeal and cloacal swabs. Strains originally isolated from quail resulted in higher numbers of birds shedding in the inoculation group; however, transmission appeared slightly more efficient with chicken-derived isolates. This study shows that virulent NDV strains have limited replicative potential and mild to moderate disease-inducing ability in Japanese quail.

Abstract:
This study was conducted to compare external and internal quality attributes and some functional property parameters of eggs from five different poultry types/species namely, Sri Lankan village chicken &amp; commercial chicken (Shaver brown), duck (Vigoa), quail (Japanese quail) and turkey (Turkey white). In addition, the impacts of cold storage (10 &ordm;C), on commercial chicken eggs and Sri Lankan village chicken eggs, over a period of three weeks were evaluated. Yolk color, shape index, egg weigh and shell thickness values of the freshly laid eggs were significantly difference among the four species (P &lt; 0.05). Yolk color of the village chicken egg was 7.30 which is significantly higher (P &lt; 0.05) than that of other species. Quail egg had the highest (P &lt; 0.05) shape index value (80.90&plusmn;0.01) and the lowest egg weight (9.47&plusmn;5.64 g). Whereas, turkey egg had the lowest (P &lt; 0.05) shape index value (69.20&plusmn;0.02) and the highest egg weight (71.48&plusmn;5.21 g). Village chicken eggs and quail eggs had significantly lower (P &lt; 0.05) eggshell thickness than that of other poultry species. The lowest eggshell thickness (0.008&plusmn;0.00 mm) was shown by quail eggs. Duck egg white had the highest (P &lt; 0.05) viscosity and foam stability whereas, commercial egg had the lowest viscosity. Further, internal quality and functional quality traits from Sri Lankan village chicken eggs and Shaver brown eggs were decreased with the increasing storage period (3 weeks) at 10 &ordm;C. Quail egg has the highest shape index and duck egg white has the highest viscosity and foam stability. Some of the egg quality traits are significantly affected by type/species of the bird and the storage time.

Abstract:
Phosphorus (P) is an essential component for all living beings. Low P diets prompt phenotypic and molecular adaptations to maintain P homeostasis and increase P utilization (PU). Knowledge of the molecular mechanisms of PU is needed to enable targeted approaches to improve PU efficiency and thus lower P excretion in animal husbandry. In a previous population study, Japanese quail were subjected to a low P diet lacking mineral P and exogenous phytase. Individual PU was determined based on total P intake and excretion. A subset of 20 extreme siblings discordant for PU was selected to retrieve gene expression patterns of ileum (n = 10 per PU group). Sequencing reads have been successfully mapped to the current Coturnix japonica reference genome with an average mapping rate of 86%. In total, 640 genes were found to be differentially abundant between the low and high PU groups (false discovery rate ≤ 0.05). Transcriptional patterns suggest a link between improved PU and mitochondrial energy metabolism, accelerated cell proliferation of enterocytes, and gut integrity. In assessing indicators of the efficient use of macro- and micronutrients, further research on turnover and proliferation rates of intestinal cells could provide an approach to improve P efficiency in poultry species.

Abstract:
Fowl typhoid a high-impact disease in the poultry industry, this study aims to verify the clinical signs of the disease in experimentally inoculated with quail Salmonella Gallinarum 54 Japanese female quails were distributed into two groups. The inoculated group (GI) SG (32 quail) and control group (CG) (16 birds). A total of six birds were euthanized before the start of the experiment, organs samples (liver, spleen, ovarian follicles, cecum and lung) were collected for the microbiological analysis. The birds of the GI group received 0,7mL of inoculum (1.5x106 CFU/mL) and birds of the CG group received 0,7 mL of saline solution. Thereafter, the quails were observed for ten consecutive days in three daily periods (8:00, 11:00 e 14:00) in order to observe clinical signs of disease. After four days of inoculation was verified prostration, apathy, ruffled feathers, diarrhea, bird's stay in the corner of the cage with closed eyes and reluctance to move (13/32). Some macroscopic changes were observed in euthanized birds with clinical signs like splenomegaly and splenic necrosis in 84,6% (11/13) and 23,0% (3/13) respectively, hepatomegaly and liver necrosis in 15,4% (2/13) e 23% (3/13) respectively, and atrophy and hemorrhage of ovarian follicles in 15,4% (2/13) and 7,7% (1/13) respectively. the birds that died was observed only hepatosplenomegaly. So we can conclude experimentally inoculated with Salmonella Gallinarum quail have the typical clinical signs of fowl typhoid observed in others birds of Galliforme order.

Abstract:
Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were administered saline, 5 mg/kg, or 10 mg/kg cocaine for 10 days. Restricted photoperiods in early life were correlated to lower gonadal hormone levels in females and males. Male quail raised on the short-light cycle developed a sensitized response to 10 mg/kg cocaine. Female quail raised on the short- or long-photoperiod developed behavioral sensitization to 5 mg/kg cocaine. Furthermore, early life reduction in estradiol in females modulated the amount of activity on day 10 of cocaine treatment. The current research extends previous research by finding a possible early life gonadal hormone control of behavioral sensitization in the quail.

Abstract:
The Japanese quail (Coturnix coturnix japonica) rearing activity has grown considerably over the past few years. The purpose of this study was to compare diet formulations based on total (TAA) and digestible amino acids (DAA) and the use of different protein sources such as meat cum bone meal and feather meal in Japanese quails. The first three treatments were based on TAA, formulated based on corn and soybean meal (CST); meat and bone meal (CSMT); feather meal (CSMFT). The three other treatments received the same sequence of ingredients as the previous treatments; however, the diets were formulated based on digestible amino acids (DAA) (CSD, CSMD, and CSMFD). The results show that the base of diet formulation improves the performance of quails from 1-21d and the quails show that is possible to replacement of soybean meal with animal-origin by-products such as meat bone meal and feather meal, buts is needed to evaluate more aspects. In conclusion, diets formulated base on DAA for Japanese quails can be utilized with the same efficiency as diets based on TAA.
