Academic literature on the topic 'Autofeeder'

n aquaculture, mainly for shrimp farming, feeding is an important thing. Feeding manually with the hand is less effective and ineffective. Thus, an automatic feeder is needed to dispense food at a predetermined time. The advantages of automatic feeders are cost-effective, reduce labor requirements, and allow large volumes of feed to feed efficiently. Autofeeder is a modern fish feeder that can be used in several ponds. Therefore, in this research, the Autofeeder has been made with PVC pipe for the feed thrower. The test results show that the speed of the electric motor after loading is 2782 rpm. Meanwhile, the thrower maximum distance is 10 m. Keywords Autofeeder, thrower, and PVC pipe

Feeding is one of the factors that influence shrimp farming. Feeding should be done regularly. The amount of feed can affect the shrimp's growth. Less amount of feed can hinder the shrimp’s growth and the shrimp become malnourished. On the other hand, the high amount of feed can cause contamination from wasted food scraps. Autofeeder is a technology that can regulate shrimp feeding. Automatic fish feeder is a tool that can automatically spread shrimp feed and adjust the frequency of feeding. Besides, the automatic fish feeder can also reduce the effort and time for farmers to feed fish. The purpose of this research is to learn about the Autofeeders operation, layout, and thrower distance in CV Putra Gunung Sari Segara, Lelateng Village, Kecamatan Negara, Kabupaten Jembrana, Bali Province. Keywords Atofeeder, layout, and the thrower distance

Poor feed intake of conventional dry diets in the immediate post-weaning period can be a major factor limiting potential growth rate in the young pig. Feeding systems based on the automatic dispensing of liquid milk -substitute have been developed over the last 10-15 years but they have not achieved widespread usage within the U.K. industry for various reasons. Several studies have shown, however, the potential benefit of offering liquid or slurry diets over this critical period around weaning (eg. English, Maclean and MacPherson 1988; Anon 1991). Deprez et a] (1987) also demonstrated its beneficial effects on the morphology of the small intestine post-weaning. The present study examined the use of an experimental automated feeder (‘Autofeeder’, patent applied for) which could dispense a conventional pelleted starter diet plus water (1:1 ratio) 6, 8, 12 or 24 times throughout the day in varying quantities. It was compared against a conventional dry hopper (control) with ad libitum feeding.

Carpenters frequently work in awkward and stooped postures. Autofeed extension screw guns (ESGs) allow certain tasks to be performed upright. This study evaluated low back and wrist motion in fifteen carpenters using a traditional screw gun (TSG) and ESG during floor level work. ESG use required a greater percentage of time in awkward wrist postures with higher velocities and accelerations, yet neither tool placed workers at risk for wrist injury. The ESG resulted in significantly less low back flexion, left-sided bending and twisting, velocity and acceleration. The probability of low back disorder group membership risk was 53% with TSG use and 47% with ESG use. Carpenters liked using ESGs and reported less exertion when using them. The ESG's autofeed feature enhanced productivity. Training may be important to further reduce back flexion and improve tool maintenance, and design changes would improve ESGs overall.

Abstract Metal as sheets are more significant. However, metal as sheets can’t be straightforwardly utilized, activities like punching, blanking, twisting, riveting, and so forth are should be done on the metal sheets. For these activities, most enormous scope fabricating businesses utilize powerfully worked machines which are not savvy, generally little and medium scale enterprises utilize hand-worked machines for completing sheet metal activity which are moderate. 6 bar pressure is enough for these machines to work. The compressed air is going through the cylinders to the chamber powers the cylinder out which thus incites the cylinder down which thus does the way toward punching or riveting. This empowers us to utilize various kinds of hardware to perform various tasks. After the consummation of punch or rivet in the sheet metal the compressed air flows to the lower part of the chamber which incites the cylinder upwards so the metal is liberated from the tool and the following punch or rivet measure is made accessible. As per the functioning material the functioning pressing factor can be changed. This empowers us to utilize various kinds of punch or rivet apparatus which helps in bringing about a wide scope of items.

We studied the clonal features of bone marrow stromal cells obtained by biopsy of the iliac wing of patients with systemic skeletal diseases: multiple exostotic chondrodysplasia (16 patients) and systemic osteoporosis (24 patients). The proliferative potential of cells was investigated, the main indicator of which is the efficiency of cloning. We analyzed the induction-morphogenetic relationship between the efficiency of cloning and biological inducers contained in the autologous and added suspension of bone marrow cells (the so-called feeder). The rapid growth and proliferation of exostoses in multiple exostotic chondrodysplasia is apparently due to both the increased proliferative activity of the cultured cells themselves, and (especially) the increase in the growth-stimulating effect of the autologous "feeder", which distinguishes fast-growing exostoses from the so-called calm ones, in which the proliferative activity itself cells are increased (but to a lesser extent), and no enhancement of the effect of the autofeed is detected. In systemic osteoporosis, a sharp decrease in the efficiency of cloning of the target cells themselves has been established, which is probably associated with a weakening of their colony-forming properties and / or a decrease in their number in the explanted suspension.

The objective of this study was to evaluate the long-term effects that early life events have on heifer growth up to 400 d of age, heifer conception rate, survivability through first lactation, and first lactation milk production of calves raised in automatic calf feeders. Chapter one evaluates possible early life variables that would affect heifer growth and lifetime production as well as research that has been done to predict future growth. The major points discussed include pre-weaning feeding strategies, automatic calf feeding systems, respiratory disease and ways to diagnose cattle with this disease, and the impact of early life growth on the future productivity of the dairy cow.

The second chapter discusses in detail the process of creating a predictive equation using significant early life variables that affect Holstein heifer growth up to 400 d of age. Variables collected for the growth analysis included sixty d cumulative milk consumption (MC), serum total protein values, respiratory disease and scours incidences, genetic body size, birthweights, and incremental body weight variables on a commercial dairy farm from October 1, 2015 to January 1, 2019. Calves were fed pasteurized whole milk through an automated calf feeding system (feeders = 8) for 60 d (range: 48 – 126d), with a 30% Crude Protein (CP) and 5% Crude Fat enhancer added at 20 g/L of milk. Calves were weighed at birth and several other times prior to calving. Average birth weight of calves was 40.6 ± 4.9 kg (mean ± SD), serum total protein was 6.7 ± 0.63 g/dL, and cumulative 60 d MC was 508.1 ± 67.3 L with a range of 179.9 to 785.1 L. Daily body weights were predicted for individual animals using a third order orthogonal polynomial to model growth curves. The linear and quadratic effects of cumulative 60 d milk consumption, birthweight, feeder, yr born, season born, respiratory incidence, and genetic body size score were significant (P<0.0001) when predicting heifer body weight at 400 d (pBW₄₀₀) of age (R²=0.31). There was up to a 263 kg difference in pBW₄₀₀ between the heaviest and lightest animal. Birthweight had a significant effect on predicted weights up to 400 d (P<0.0001), and for every 1 kg increase in birthweight, there was a 2.5 kg increase in pBW₄₀₀. The quadratic effect of cumulative 60 d MC was significant for pBW₄₀₀ (P<0.0001). When 60 d MC was divided into quartiles, heifers had the highest pBW₄₀₀ in the third quartile, when 60 d MC was between 507.8 and 552.5 L. Body size composite (genomic index) showed a 21.5 kg difference in pBW₄₀₀ between the top and bottom 25^th percentile of heifers. Heifers were 4.2 kg lighter at 400 d if treated for respiratory disease 3+ times during the first 60 d of life, compared to heifers not treated for respiratory disease.

The third chapter utilizes the data described in chapter two and followed those heifers through breeding and first lactation. Heifer conception age and 280 d first lactation milk production (280M) were collected. Average age at conception was 437.5 ± 45.0 d; range of 308 to 631 d (n=5,193), and average 280M was 9,305 ± 1,371.8 kg; range of 712-13,358 kg (n=1,324). Heifer conception age was impacted by season, yr, and the quadratic effects of predicted bodyweight at 300 d of age (pBW₃₀₀) and ADG (0-400; all P < 0.05; total model R² = 0.08). Season born, ADG (0 - 400 d), genomic milk, and the linear effect of heifer conception age had a significant impact on 280M (all P < 0.05; R² = 0.28). For every 1 kg increase in genomic milk value there is 1.42 kg increase in first lactation 280M. Calves not diagnosed with bovine respiratory disease (BRD) from 60-120 d old had a significantly higher chance for survival to first lactation than animals treated three or more times for BRD (hazard ratio = 0.71, 95% CI = 0.574 to 0.886, P = 0.0023, Table 3.3). Heifers treated twice or more for BRD had reduced likelihood to become pregnant than heifers not treated for BRD from 60-120 d (twice P = 0.02; three or more P = 0.05).

In conclusion, the results from this thesis support that early life events in Holstein heifers continue to influence future growth and productivity. Future research aims to validate the predictive equation generated in chapter two on farm as well as adapt the equation to other farms allowing them to utilize it as well. The goal is to have farms utilize this tool to aid in their replacement heifer management decisions and to select the most productive heifers for the future of their herds.
