Methods to evaluate the eggshell quality of table eggs
(2019-01-01)
The objectives of this study were to determine the most suitable probe diameter and egg position to perform the eggshell breaking strength test using a texturometer, as well as the most reliable parameter to estimate ...
Brown-and-yellow marshbirds reduce their acceptance threshold of mimetic brood parasite eggs in the presence of non-mimetic eggs
(Springer Tokyo, 2016-01)
The recognition and subsequent rejection of brood parasite eggs is one of the most commonly observed defensive behaviors of the host. The brown-and-yellow marshbird (Pseudoleistes virescens) is a common host of the shiny ...
Penetration time of Salmonella Heidelberg through shells of white and brown commercial eggs
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2010-12-01)
This study aimed at determining the minimum time required for the penetration of Salmonella Heidelberg inside the eggs after contact with contaminated material. Recently-collected brown and white eggs from laying hens ...

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 ...
Digestible threonine-to-lysine ratio in diets for brown egg-laying hens
(Oxford Univ Press, 2019-03-01)
The objective of this study was to evaluate the levels of digestible threonine to determine the ideal digestible threonine-to-lysine ratio in the diet of brown egg-laying hens aged 42-54 wk. A total of 270 Dekalb Brown ...

Thick eggshells of brood parasitic cowbirds protect their eggs and damage host eggs during laying
(Oxford University Press, 2018-07)
Brood parasites lay thick-shelled eggs and numerous hypotheses have been proposed to explain the significance of this trait. We examined whether thick eggshells protect the parasite egg during laying events. We used eggs ...
