Growth curve analyses in poultry science
(Cambridge Univ Press, 2017)
Growth is a key characteristic of animals and can be defined as any change in body size per time unit, and is influenced by genotype and environment. Mathematical functions called 'growth models' have been used to explain ...
Effects of monochromatic light stimuli during embryogenesis on some performance traits, behavior, and fear responses in Japanese quails
(Oxford Univ Press, 2018)
Lighting is crucial in poultry rearing and the subjects with light intensity, source, and color having been addressed in numerous studies. Numerous studies with monochromatic light from light-emitting diode (LED) bulbs ...
Effects of mass selection on egg production on some reproductive traits in Japanese quail
(Eugen Ulmer Gmbh Co, 2017)
Most of the selection studies in Japanese quail have focused on high body weight or short-term egg production. The effect of selection on long-term egg production is not well known. Japanese quail lines were subjected to ...
Effects of Multi-Trait Selection on Phenotypic and Genetic Changes in a Meat Type Dam Line of Japanese Quail
(Kafkas Univ, Veteriner Fakultesi Dergisi, 2014)
The present study in Japanese quail was aimed to develop multi-trait genetic selection program for meat type dam line utilizing the mixed-model methodology. In total, 2000 pedigreed quail were formed the basis of the ...
Effects of slaughter age and mass selection on slaughter and carcass characteristics in 2 lines of Japanese quail
(Oxford Univ Press, 2014)
The aim of this study was to evaluate the relationship between slaughter age and slaughter-carcass characteristics in 2 quail lines. With this aim, a Japanese quail flock subjected to mass selection to increase BW for 4 ...
Egg shell quality in Japanese quail: characteristics, heritabilities and genetic and phenotypic relationships
(Cambridge Univ Press, 2015)
The objective of the present study was to estimate heritabilities as well as genetic and phenotypic correlations for egg weight, specific gravity, shape index, shell ratio, egg shell strength, egg length, egg width and ...
