Albendazole treatment in laying hens: Egg residues and its effects on fertility and hatchability
(Wiley Blackwell Publishing, Inc, 2018-10)
This work characterized the egg residual concentrations of albendazole (ABZ) and its sulphoxide (ABZSO) and sulphone (ABZSO2) metabolites and evaluated their effect on egg fertility and hatchability after ABZ treatments ...
Effects of Ascorbic Acid Injection in Incubated Eggs Submitted to Heat Stress on Incubation Parameters and Chick Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-04-01)
Dose-dependent positive effects on hatchability and hatchling weight have been attributed to ascorbic acid (AA) when eggs were submitted or not to intermittent heat stress during incubation. Fertile breeder (Cobb (R)) eggs ...
Effects of thymol and isoeugenol feed supplementation on quail adult performance, egg characteristics and hatchling success
(Taylor & Francis Ltd, 2012-10)
1. A study was conducted to evaluate whether feed supplementation with thymol or isoeugenol can alter Japanese quail growth rate and final body weight, the female onset of puberty, henday egg production and the physical ...
Effect of breeder age on eggshell thickness, surface temperature, hatchability and chick weigh
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2012-03-01)
Two experiments were carried out to study the effect of breeder age on incubation parameters (hatchability, eggshell thickness, egg surface temperature and chick weight). In Exp. 1, fertile eggs (30- and 60-wk-old breeders) ...
