Sanitary Management of the Hatching Eggs
Unquestionably, the sanitary quality of the hatching eggs will affect the quality of the day-old chicks. The egg leaves the oviduct free of any microorganisms (except for vertically-transmitted pathologies), but even eggs which are laid « clean » present a wide diversity of bacteria on the shell. Furthermore, after being laid, the egg’s temperature drops (from 41 to 21°C), which causes embryoni...
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 کاملSalmonella penetration of egg shells and proliferation in broiler hatching eggs--a review.
The presence of salmonellae in fertile broiler hatching eggs has been clearly identified as a critical control point in the salmonellae contamination of broiler chickens. This paper reviews the published research studies on a) the penetration and proliferation of salmonellae in hatching eggs, b) the consequences of this contamination on the contamination of the final product, and c) the egg's d...

متن کاملAlbumen height and yolk and embryo compositions in broiler hatching eggs during incubation.
The relationship of albumen height (AH) to the compositions of yolks and embryos in hatching eggs from a young (30 wk of age) broiler breeder flock was evaluated during incubation. On Day 2 of incubation, egg weight, yolk weight, and yolk moisture, lipid, and fatty acid contents were determined in eggs from broiler breeders previously identified as laying eggs of either low or high AH. In addit...
