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 کاملGluconeogenesis differs in developing chick embryos derived from small compared with typical size broiler breeder eggs.
We hypothesized that, as the supply of preformed glucose diminishes during development, the embryo would transition to a greater rate of gluconeogenesis (GNG) and that GNG would be greater in embryos from small vs. typical size eggs. Gluconeogenesis by embryos from small (51.1 +/- 3.46 g) and typical size (65 +/- 4.35 g) broiler breeder eggs was measured by dosing [(13)C(6)]glucose (15 mgxegg(-...
متن کاملEmbryonic Growth, Hatching Time and Hatchability Performance of Meat Breeder Eggs Incubated under Continuous Green Light
The effects of dark-control (D) and continuous green light (GL) exposure of incubated meat-type breeder eggs (Hybro) on embryonic growth from 5 to 15 days of age, hatching time, hatchability per cent and chick hatching weight were investigated in three consecutive experiments at 33, 38, and 41 weeks of age. A total of 798 eggs were used in this study. Eggs were set in an incubator on trays eith...
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...
