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 ...
Irregularly calcified eggs and eggshells of Caiman latirostris (Alligatoridae: Crocodylia)
(Springer, 2013-05)
We describe irregularly calcified egg and eggshell morphologies for the first time in nests of the broad-snouted caiman, Caiman latirostris. Research is based on detailed descriptions of 270 eggs from a total sample of ...
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 ...
Effect of dietary organic selenium and zinc on the internal egg quality of quail eggs for different periods and under different temperatures
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-03-01)
The objective of this study was to evaluate the internal quality of eggs of Japanese quails fed diets supplemented with chelated selenium and zinc. The experiment was carried out for 120 days, and 144 birds were divided ...
