Influence of a Commercial Hatchery Thermal Environmental on the Heat Loss of Fertile Broiler Eggs
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2016-10-01)
The objectives of this study were to monitor the thermal environment of different hatchery locations during the transfer of fertile eggs from the setter and to the hatcher, to measure egg heat loss, and to determine its ...
Effect of organic selenium and zinc on the performance and egg quality of Japanese quails
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-06-01)
The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. ...
Prediction of the metabolizable energy requirements of free-range laying hens
(Amer Soc Animal Science, 2016-01-01)
This experiment was conducted with the aim of estimating the ME requirements of free-range laying hens for maintenance, weight gain, and egg production. These experiments were performed to develop an energy requirement ...
Physical and chemical characteristics of fertile and infertile eggs of wild Caiman latirostris
(Elsevier Science, 2018-12-01)
In oviparous species, physico-chemical characteristics of eggs are an indicator of maternal physiological traits and environmental conditions of the site where the females develop. In this study, we aim to (a) determine ...
Dietary combination of chelated zinc and threonine and effects on egg production, egg quality and nutrient balance of Brown laying hens from 20 to 49 weeks of age
(2020-09-01)
Studies have evaluated the effects of zinc (Zn) supplementation as an important dietary factor that regulates intestinal amino acid metabolism, protecting and preventing diarrhea. Threonine (Thr) also plays an important ...
