Effect of post-hatch transportation duration and parental age on broiler chicken quality, welfare, and productivity
Broiler chicks are transported to production sites within one to 2 d post-hatch. Possible effects of this transportation are poorly understood and could vary among chicks from breeder flocks of different ages. The aim of the present study was to investigate the effects of transportation duration and parental flock age on chick welfare, productivity, and quality. After hatch in a commercial hatc...
متن کاملSpread of hatch and delayed feed access affect post hatch performance of female broiler chicks up to day 5.
It is not rare that newly hatched chicks remain without feed for about 24 to 48 h before they are placed on farms due to a series of logistic operations. Furthermore, the spread in hatching time can also mount up to 30 to 48 h for late v. early hatchers. In other words, the practice is a complex combination of spread of hatch and delayed feed access. The present study was aimed to investigate t...
متن کاملEffect of in ovo injection of vitamins on the chick weight and post-hatch growth performance in broiler chickens
An experiment was conducted to study the effect in ovo injection of vitamins on the embryonic and post-hatch growth performance. Fertile eggs (n=350) were weighed, distributed in to 7 groups and set in force-draft incubator. On 14 th ED five groups were injected with 100 IU Vitamin-A, 0.5 IU Vitamin-E, 50 mg Vitamin-C, 100 μg Vitamin B1 and 100 μg Vitamin B6 dissolved in 0.5 ml of sterile water...
متن کاملEffect of Post Hatch Feed Deprivation on Yolk-sac Utilization and Performance of Young Broiler Chickens
An experiment was conducted to study the effect of post-hatch feed deprivation on yolk sac utilization and subsequent performance of young broiler chickens (280) up to 35 days of age. The experimental treatments included access to feed at 8 h intervals after hatch, up to 48 h (0, 8, 16, 24, 32, 40 or 48 h). Water was offered ad libitum to all the groups immediately after placement. Results indi...
متن کاملChanges in broiler chick tissue concentrations of lipid-soluble antioxidants immediately post-hatch.
The antioxidant protection of the chicken (Gallus gallus) embryo during incubation and early postnatal development plays an important role in chick viability. To assess the antioxidant capacity of the newly hatched chick, we determined the concentrations of vitamin A, vitamin E, carotenoids and coenzyme Q₁₀ in the major tissues of chicks which had been held in an incubator for up to 36 h post-h...
