a study was conducted to evaluate the effects of two laying systems (floor versus cage) on egg production, egg quality, and microbial safety. one hundred and eighty 42 wk old laying hens were separated into two groups of 90 hens each, and housed in laying cages and a floor laying system. eggs from the hens were collected for 2 weeks, and hen-day egg production, egg quality (whole egg, albumen, ...

the aim of the study was to evaluate the effect of storage and temperature on egg physical quality in hyline chickens line. a total of 150 eggs from college of natural resources farm were sampled for the present experiment. about 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚c; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚c; relative hu...

This study aimed to characterize production and reproduction performances in Rhode Island Red-White strain chicken developed and maintained at the Central Avian Research Institute, Izatnagar. Three hundred and forty six fertile eggs were set in automated electric incubation and 234 chicks were investigated in three hatches. The performance data was analyzed by least squares analysis of variance...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

artificial neural networks (ann) have shown to be a powerful tool for system modeling in a wide range of applications. the focus of this study is on neural network applications to data analysis in egg production. an ann model with two hidden layers, trained with a back propagation algorithm, successfully learned the relationship between the input (age of hen) and output (egg production) variabl...

this experiment was conducted to evaluate effects of different levels of mineral and vitamin premixes with wheat and corn base diets on performance and egg traits of laying hens. experiment carried out as 2*5 factorial include wheat and corn base diets and 5 levels of minerals and vitamin premixes (0, 0.25, 0.35, 0.45 and 0.55 percentage) in a completely randomized design with 360 hi-line (w36)...
