Welfare, health, and hygiene of laying hens housed in furnished cages and in alternative housing systems.
The aim of this review was to compare welfare, health, and hygienic status of laying hens housed in furnished cages and in alternative systems. In alternative systems (floor housing and aviaries), birds have more freedom of movement and a more complex environment than in furnished cages. However, housing birds in much larger flocks in alternative systems leads to an increased risk of feather-pe...
متن کاملEffect of space allowance and cage size on laying hens housed in furnished cages, Part I: Performance and well-being
There are few published data on the effects of housing laying hens at different densities in large furnished cages (FC; a.k.a. enriched colony cages). The objective of this study was to determine the effects of housing laying hens at 2 space allowances (SA) in 2 sizes of FC on measures of production and well-being. At 18 wk of age, 1,218 LSL-Lite hens were housed in cages furnished with a curta...
متن کاملPerformance and Serum Hepatic Enzymes of Hy-Line W-36 Laying Hens Intoxicated with Dietary Carbon Tetrachloride
An experiment was conducted to study the effects of carbon tetrachloride (CCl4) on post-peak performance and serum enzymes of Hy-Line W-36 laying hens from 32-36 weeks of age. The experiment was carried out with a total of 192 laying hens in a completely randomized block design. During the experiment laying hens were allocated to 4 groups consisted of T1) no CCl4 as control diet, T2, T3 and T4)...
متن کاملEffects of Rice Bran and Phytase Supplementation on Performance, Egg Quality, and Biochemical Parameters of Comercial Hy-Line Hens
Rice bran (RB) is a major by-product, produced from the rice milling process. This study was conducted to evaluate the performance, egg quality, and blood biochemical parameters of 288 Hy-line laying hens fed diets with rice bran and commercial microbial phytase Natuphos®5000. The experiment was a 4×2 factorial one with four RB levels (0, 5, 10, and 15%) by two phytase levels (0 and 5000 FTU/kg...
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...
