Effects of Age of Broiler Breeders and Egg Storage on Egg Quality, Hatchability, Chick Quality, Chick Weight, and Chick Posthatch Growth to Forty-Two Days
Nutritional and environmental conditions influence broiler flock performance. Besides these factors, other less-well-understood factors, such as incubating egg characteristics, affect the embryonic life of chicks. This study demonstrated that egg storage depressed egg albumen Haugh units (HU) and chick quality; these effects of storage were greater in egg and chicks from old breeders. Absolute ...
متن کاملEffect of egg weight and position relative to incubator fan on broiler hatchability and chick quality.
Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...
متن کاملEffects of dietary taurine on egg weight.
Two experiments were conducted to determine whether taurine supplementation to laying hens would influence laying performance. In Experiment 1, a total of 120 White Leghorn hens were fed diets supplemented with 0, 0.25, or 0.5% taurine for 5 wk. Egg weight was reduced significantly by supplementing 0.25 and 0.5% taurine; however, taurine did not affect other laying performance variables. In Exp...
متن کاملEffect of Egg Weight on Egg Traits and Hatching Performance of Turkey (Meleagris gallopavo) Eggs
The study was conducted to determine the effects of turkey (Meleagris gallopavo)egg weight on certain egg traits and hatching performance. A total of 178 turkey eggs comprising of three different egg weight groups below 60 g (G I), 61 to 69 g (G II) and above 70 g (G III) were used for this study. Average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...
متن کاملEffect of Hatching Egg Size on Hatchability and Chick Hatch-weight of Indigenous Venda Chickens
An experiment was conducted to determine the effect of hatching egg size on hatchability and hatch-weight of indigenous Venda chickens (Gallus gallus domesticus). Three different egg size groups classified into small: (<49 g) medium: (50-59 g) and large:(60-69 g) were used in the experiment. A complete randomized design was used for the experiment. Simultaneously a quadratic type equation was u...
