Hatching Egg Sanitation
نویسنده
چکیده
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 common disinfectants currently available for use in hatcheries and on eggs.

Evaluation of a method of ultraviolet light sanitation of broiler hatching eggs.
Sanitation of hatching eggs is an important area of research due to the need for an effective, economical, and safe method of egg sanitation. Improved hatching egg sanitation is an important part of an overall pathogen reduction program within integrated poultry operations. This must be accomplished without disturbing the cuticle of the egg, which can decrease hatchability. The ability of ultra...
متن کاملSpraying hatching eggs with electrolyzed oxidizing water reduces eggshell microbial load without compromising broiler production parameters.
An experiment was conducted to determine whether spraying hatching eggs with electrolyzed oxidizing (EO) water would decrease eggshell microbial load and hence improve hatchability, chick quality, and broiler growth performance. Eggs were collected from a broiler breeder flock; half the eggs were sprayed with EO water and the other half were left untreated. Enterobacteriaceae and total aerobic ...
متن کاملNest Sanitation as the Evolutionary Background for Egg Ejection Behaviour and the Role of Motivation for Object Removal
Higher interclutch colour variation can evolve under the pressure of brood parasitism to increase the detection of parasitic eggs. Nest sanitation could be a prerequisite for the evolution of anti-parasite defence in terms of egg ejection. In this respect, we used nest sanitation behaviour as a tool to identify: i) motivation and its underlying function and, ii) which features provoke ejection ...

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...

Microorganisms contamination in hatcheries has serious impacts on the quality and growth performance of ostrich. This study was conducted to examine the bacterial contamination of an ostrich hatchery environment and hatching eggs. Additionally, the inhibitory effects of some commercial disinfectants on microbial contamination on hatchery floor were also investigated. Our results indicated that,...
