Egg temperature and initial brood patch area determine hatching asynchrony in Magellanic Penguin Spheniscus magellanicus
(Wiley Blackwell Publishing, Inc, 2016-01)
In birds, the adaptive significance of hatching asynchrony has been under debate for many years and the parental effects on hatching asynchrony have been largely assumed but not often tested. Some authors suggest that ...
Lichens in the nests of European starling Sturnus vulgaris serve a mate attraction rather than insecticidal function
(Tubitak Scientific & Technical Research Council Turkey, 2018-07)
The European starling Sturnus vulgaris is a hole-nesting bird in which the male builds a voluminous nest using a wide variety of materials such as twigs, grass, leaves, feathers, and lichens. The function of lichens in ...
The influence of diet composition on egg and chick traits in captive Greater Rhea females
(Taylor & Francis, 2013-01)
1. This study was conducted to evaluate the influence of diet composition on egg number,physical and chemical characteristics of eggs and weight and survival of chicks throughout a breeding season in a captive-bred population ...
Pubic spread development and first egg lay in Japanese quail
(Poultry Science Association, 2004-07-01)
Measurement of the space between the pelvic ("pin") bones, also known as pubic spread (PS), is used to determine the state of sexual development of female broiler breeders. Herein, we examined PS at selected intervals ...
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 ...

Dos líneas de codornices fueron seleccionadas por una alta o baja respuesta de corticosterona plasmática a un estrés agudo por inmovilización (LARCP y LBRCP respectivamente). El objetivo fue determinar si la selección ha ...
Tick Gené’s organ engagement in lipid metabolism revealed by a combined transcriptomic and proteomic approach
(Elsevier, 2019-06)
Lipids play key roles in arthropod metabolism. In ticks, these biomolecules are transported from fat body to other organs, such as ovary and Gené’s organ. Gené’s organ, an apparatus found exclusively in female ticks, ...
Description of a model to optimise the feeding of amino acids to growing pullets
(2016-01-02)
Abstract: 1. A nutrition model is described that may be used to optimise the amino acid nutrition of laying-type pullets prior to the onset of lay. It is not a method of optimising lifetime laying performance. 2. The ...
