Effect of Pre-storage Heating of Broiler Breeder Eggs, Stored for Long Periods, on Hatchability and Chick Quality
This study was undertaken to determine if pre-storage heating of broiler breeder eggs, stored for long periods, would improve the hatchability and chick quality. A total of 2400 broiler breeder eggs were obtained from a 46 weeks old commercial flock. Eggs were distributed in a 3 x 4 factorial design, with three pre-storage heating durations (0, 6, and 9 hours at 37.5° C and 56% RH) and four sto...
متن کاملThe Effect of Broiler Breeder Strain and Parent Flock Age on Hatchability and Fertile Hatchability
The effect of genetic strain (Ross 308; Cobb 500) and parent flock age (Ross at 32 and 36 weeks; Cobb at 26 and 44 weeks of age) on hatchability, fertile hatchability, Egg Weight Loss (EWL) and egg break out analysis were examined. At each flock age, 300 eggs from each treatment group were incubated. Thirty eggs from each treatment group were labeled individually for the measurements of Egg Wei...
متن کاملThe effect of eggshell thickness on hatchability of quail eggs
BACKGROUND AND AIM The aim of the successful incubation period is to achieve maximum health chicks in each batch. Therefore, all factors affecting incubation have to be investigated in detail. This study investigated the effect of eggshell thickness on hatchability of quail eggs. MATERIALS AND METHODS A total of 1415 eggs were collected from the same flock at the ages of 23 and 41 weeks. Two ...
متن کاملThe Effect of Photoperiod and Feeding Time on Broiler Breeder Eggshell Quality and Oviposition Time
This study was conducted to determine the effect of photoperiod and feeding time on oviposition time and eggshell quality of broiler breeders. Five experiments were conducted in total. The effect of photoperiod on oviposition time was tested in Experiments '1 and 2. Experiment 1 involved 3200 33-week old broiler breeder hens housed in floor pens and subjected to photoperiods of 10, 11, 12, 13, ...
متن کاملEffect of Storage, Pre-heating and Turning during Holding Period on the Hatchability of Broiler Breeder Eggs
Two hundred forty fertile eggs of an average weight of 52-55g were taken from 32 weeks old broiler breeder flock. These eggs were divided into four groups i.e. A (Without turning and preheating), B (No turning but preheated), C (Turned but without preheating), and D (given both treatments preheating and turning) with 60 eggs in each group. The eggs were stored with broad end upward at 16-20°C a...
