Conventional Manner

An experiment was conducted to evaluate the effects of two different hatching-egg storage environments on the subsequent performance of broiler chickens. The two environments involved: (1) an improved egg storage method consisting of eggs packed small endup on fiber trays, enclosed in vinylidene (Cryovac) bags flushed with nitrogen gas; and (2) eggs packed in the conventional manner small end-down on fiber trays. The effects of preincubation fumigation was also evaluated. A 20-min fumigation was conducted prior to packing the eggs using 1.5 ml formalin and 1 g potassium permanganate per 0.028 m3 of fumigation chamber. Fumigated eggs were ventilated 24 hr before packaging. The improved storage method resulted in the higher hatchability of broiler chicks, lower mortality, higher growth rate, and higher monetary returns to 8 weeks of age compared with chicks hatched from eggs stored under conventional conditions. There were no significant differences in the performance of chicks hatched from eggs stored for 23 and 30 days under the improved storage method and chickens hatched from eggs held only 2 days prior to incubation. Fumigation effects on subsequent bird performance appeared to have no important effect. It is concluded that deleterious effects on chick performance associated with the prolonged storage of hatching eggs under conventional methods can be reduced or eliminated by using improved egg storage methods.

First, this study aimed to evaluate the effects on hatchability of in ovo supplementation of beta alanine (βA). Second, it assessed the effects on performance, meat quality and serum constituents of broiler chickens of βA injection in ovo and of supplementation with βA in feed for the first seven days after hatching. For this purpose, 960 fertilized broiler chicken eggs were distributed to hatchery trays in four treatment groups with six replicates on day 17 of incubation. The treatment groups consisted of eggs that were not injected (T1; negative control), injected with sterile solution with 0.9% salt (T2; positive control), injected with in ovo 1% βA solution (T3), and not injected, but with chicks were fed 1% βA for the first seven days after hatching (T4). Upon hatching, chicks from T1, T2, and T3 were fed commercial starter feed. All treatments were assessed with six replicates of 28 birds (14 females and 14 males) throughout the grow-out period. As a result of this study, T3 increased hatchability, yolk-free hatching weight and chick quality, and decreased yolk weight and feed access time at hatch. Both T3 and T4 improved carcass yield and meat quality, and T3 increased serum total antioxidant status at 42 days afer hatching. The results demonstrated that in ovo βA feeding improved hatching characteristics, and βA administration in ovo or in feed improved carcass yield and meat quality without affecting growth performance.

This study investigated the effects of pre-storage heating and storage period of hatching eggs on hatchability traits and chick quality of Dokki-4 (Egyptian local strain of chickens) laying hens. A total of 3600 eggs were collected from 46-week-old laying hens. Eggs were distributed in a 3x4 factorial arrangement, with three storage times (4, 8 and 12 days at 18°C and 75% RH) and four heat treatments prior to storage (0, 3, 6 and 9 hours at 37.5°C and 56% RH). Eggs were distributed to twelve treatments of 20 replicates. After storage, eggs were incubated under the normal conditions of incubation at the same time. The results showed that the long storage period increased egg weight loss. Hatchability and chick quality results from 8-12 days stored eggs were lower than eggs stored for 4 days. The 6-hour pre-storage heating system substantially improved egg hatchability and chick quality relative to non-heated or 9-hour heating. Important interactions were observed during pre-storage heating × egg storage time for loss in egg weight, hatchability of total and fertile eggs, embryonic mortality and chick quality. When eggs were stored for more than four days, pre-storage heating of hatching eggs for six hours improved hatchability and chick quality compared to unheated eggs or heated for 9 hours. Conclusively, pre-storage heat treatment beneficially affects hatchability traits and chick quality, especially when hatching eggs are stored for long periods.
