Multiple Lines of Egg Defense in a Neotropical Arachnid with Temporary Brood Desertion
(Berlin, 2014-07)
Egg predation is the one of the main costs of brood desertion in many ectothermic animals. When stressful environmental conditions constrain parental activities to only some periods of the day, the combination of physical ...
How Does Oocyte Uptake Occur? A Macroscopic Study of the Ovarian and Oviductal Modifications for Egg Capture in the Coral-Snake Micrurus corallinus
(2018-11-01)
The processes of follicular development, ovulation, egg capture, and egg transport vary among vertebrates. Therefore, analysis of the reproductive tract of several lineages is needed for understanding the evolutionary ...
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 ...
Estimates of genetic parameters, and cluster and principal components analyses of breeding values related to egg production traits in a White Leghorn population
(Poultry Science Assoc Inc, 2011-10-01)
The objectives of this paper were to identify the phenotypic egg-laying patterns in a White Leghorn line mainly selected for egg production, to estimate genetic parameters of traits related to egg production and to evaluate ...

Effects of amylin on egg quality traits of hens during the early laying period
(Brazilian Journal of Animal Science, 2023)
Incidence of parasitoids and predators on eggs of seven species of Therididae (Araneae)
(2012)
Although many characteristics of the egg sacs of spiders likely evolved to reduce the effect of parasites and predators that attack their eggs, many parasite and predator insects have become specialized on spider eggs. ...
Performance and egg quality of Japanese quails submitted to cyclic heat stress
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2012-03-01)
Aiming at evaluating the influence of cyclic temperatures on the performance and egg quality of Japanese quails an experiment was carried out with 480 birds after egg production peak. Birds were housed in a bioclimatic ...

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 ...
