Breeder Age and Zinc Source in Broiler Breeder Hen Diets on Progeny Characteristics at Hatching
Metabolic, immune, and physical status of chicks can impact the incidence of morbidity and mortality of broilers during the first week of production. Assessments of chick quality are made primarily by subjective observations with few quantitative measurements. Given a better understanding of how broiler breeder hen age and nutrient intake may influence progeny physiology, certain actions can be...

متن کاملEffect of flock age, length of egg storage, and frequency of turning during storage on hatchability of broiler hatching eggs.
Broiler hatching eggs from two young (30 and 31 wk) or two old (52 and 53 wk) breeder flocks were stored for 3, 7, or 14 d at 18 C and 75% RH while being turned 0, 4, or 24 times per day in two experiments. Apparent fertility and hatchability of total eggs differed with flock age in both experiments, but the effect was greater in Experiment 1. Hatchability of total and fertile eggs were decreas...
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 کاملBIBLIOGRÁFICA - Broiler adaptation to post - hatching period
In the latest years more attention has been given to mechanisms for bird adaptation at post-hatching period by management of environmental conditions and formulations of diets offered during this period when digestive, immune, and thermo-regulating systems suffer slight changes. In posthatching period, digestive system is anatomically complete, but its functionality is still immature in relatio...
