Effect 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...
متن کاملEffect 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 کاملEffect of short-term pre-hatch heat shock of incubating eggs on subsequent broiler performance
________________________________________________________________________________ Abstract The aim of this study was to investigate the effect of thermal conditioning of broiler chickens during embryonic development on subsequent performance under standard rearing conditions. During incubation eggs from 32-, 45and 56-week old Ross 308 broiler parent stock were subjected to a 2 h heat shock of 39...
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 کاملEffects of Electric Field During Incubation of Eggs on the Hatchability and Post-Hatch Performance of Meat Chickens
The effects of electric field (EF) during incubation of eggs on hatchability traits, and post-hatch performance, nutrient utilization and carcass characteristics of meat chickens were investigated in 2 trials. Eggs from a meat-type breeder flock were incubated under EF of 30kV/m, 60Hz during the first 18 d of incubation as compared with the control incubation treatment (C). Chicks hatched from ...
