Hatching Egg Sanitation
Penetration of the hatching egg shell by microorganisms results in embryonic mortality, weak chicks, high chick mortality, and poor chick growth. The most effective sanitation system involves treating the eggs as soon as they are collected from the nest and before microorganisms penetrate the shell. Several recent research studies have examined the effectiveness, safety and ease of use of commo...
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...
متن کاملEffect of Egg Disinfection on Hatching Performance for Bandarah Chicken Strain
Four thousands and two hundred hatching eggs were obtained from Bandarah chicken to evaluate the effect of chemical and natural eggs disinfectants and fumigation on egg weight loss, embryonic mortality, hatchability, hatch time, chick weight, and chick weight loss. Three incubation trials were done, each one contained 1400 hatched eggs and divided into fourteen treatments (100 eggs per each). F...
متن کاملCrocodile egg sounds signal hatching time
Crocodilians are known to vocalize within the egg shortly before hatching [1,2]. Although a possible function of these calls - inducing hatching in siblings and stimulating the adult female to open the nest - has already been suggested, it has never been experimentally tested [1-5]. Here, we present the first experimental evidence that pre-hatching calls of Nile crocodile (Crocodylus niloticus)...
