Evaluation of Two Laying Systems (Floor vs. Cage) on Egg Production, Quality and Safety
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, ...

متن کاملLaying performance and egg quality in hens kept in standard or furnished cages
A total of 1992 ISA Brown hens were housed from 18 to 70 weeks of age, in four different types of cages: 2 models of standard cages (S5 and S6) and 2 models of furnished cages (F7 and F15). These cages housed 5, 6, 7 and 15 hens respectively with areas per hen of 660, 635, 826 and 1134 cm2. Furnished cages were fitted with a nest, a dust-bath and perches. The mortality rate was higher in the st...
متن کاملEffect of Different Levels of Germinated Barley on Performance and Egg Quality in Laying Hen
Objective: The experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. Methods: One hundred and twenty laying hens, 44-weeks old, Lohmann LSL hens were used in this experiment. Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment w...
