Effects 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 ...
متن کاملGas exchange during storage and incubation of Avian eggs: effects on embryogenesis, hatchability, chick quality and post-hatch growth
Embryonic development is a dynamic process that requires a fine balance between several factors in order to achieve an optimum hatchability and chick quality. These factors include the background of the embryo, such as genetic line of the breeders, the age of the breeder, egg weight, and factors related to the environment in which the egg is stored and incubated, such as temperature, humidity, ...
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 effects of prestorage incubation and length of storage of broiler breeder eggs on hatchability and subsequent growth performance of progeny
A total of 1 200 broiler breeder eggs were collected from a commercial flock at the hen age of 37 weeks and divided into storage treatments of 5 and 15 days. Prior to storage, the eggs were further divided into pre-storage incubation (PRESI) 0 (control), 4 and 8 h treatments. Eggs in the 4 and 8 h PRESI treatment were incubated at a standard dry-bulb temperature of 38.0°C. All eggs were weighed...
متن کاملThe Effects of Prestorage Incubation of Quail Breeder Eggs on Hatchability and Subsequent Growth Performance of Progeny
Introduction A number of methods have been investigated to improve the hatchability of eggs stored for more than seven days. Recently, it was reported that pre-heating of poultry eggs before storage resulted in more live chicks and a lower level of embryonic mortality compared to eggs that were not heated [2, 6, 7, 10]. However, no previously conducted research has tested pre-incubation storage...
