Effects of the commercial in ovo injection of 25-hydroxycholecalciferol on the hatchability and hatching chick quality of broilers.
The effects of the in ovo injection of commercial diluent containing various levels of 25-hydroxycholecalciferol [25(OH)D3] on hatchability and hatching chick quality variables in Ross × Ross 708 broilers were examined in 2 trials. All treatment groups, each containing 21 and 40 eggs in trials 1 and 2, respectively, were randomly represented on each of 10 replicate tray levels of a single-stage...
متن کاملEffects of In-ovo Injection of Different Nutrients on the Hatchability and growth Performance in Broilers
The aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of Ross 308 broiler chicks. Fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...

متن کاملEffects of a combined hatching and brooding system on hatchability, chick weight, and mortality in broilers.
Chicks hatch over a time window of approximately 36 to 48 h and are removed from the hatchers only when the majority of the chicks has hatched. Consequently, chicks are exposed to prolonged posthatch holding periods and delays in feed and water access, leading to dehydration and impaired posthatch performance. It is questionable whether the physiological requirements of the hatchlings can be me...
