Genetic parameter estimates of weekly body weight and Richard's growth curve in Japanese quail
(Eugen Ulmer Gmbh Co, 2016)
This study was conducted to estimate heritabilities and genetic correlations for growth traits in a randomly mated and non-selected Japanese quail population. To this end, a total of 1108 pedigree recorded quail were used. ...
The Influence of Body Weight on Carcass and Carcass Part Yields, and Some Meat Quality Traits in Fast- and Slow-Growing Broiler Chickens
(Kafkas Univ, Veteriner Fakultesi Dergisi, 2015)
This study aimed to compare the carcass and meat quality of fast- and slow-growing (FG and SG) broiler chicken genotypes in different slaughter weight as 1.5, 2.0, and 2.5 kg [light (L), medium (M), and heavy (H), resp.]. ...
An Application of Bootstrap Technique in Animal Science: Egg Yolk Color Sample
(Kafkas Univ, Veteriner Fakultesi Dergisi, 2015)
In this study, it was aimed to introduce the Bootstrap technique and to reveal the relationship between measurements of yolk color fan grades and digital colorimeter that is used for determining the yellow color of egg by ...
Effects of thermal manipulations during embryogenesis of broiler chickens on developmental stability, hatchability and chick quality
(Cambridge Univ Press, 2016)
Stress based on high temperature and humidity reduces the production performance of fast-growing broilers and causes high mortality. Temperatures higher than optimum have been applied to broilers in the embryonic period ...
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 ...
Differences in Internal Egg Quality Characteristics between White and Brown Shell Eggs
(Amer Inst Physics, 2017)
This study was conducted to reveal the differences among the internal quality characteristics of brown and white shell table eggs and to examine the relationship between quality characteristics. A total of 235 eggs from ...
Effects of Multi-Trait Selection on Phenotypic and Genetic Changes in Japanese Quail (Coturnix coturnix japonica)
(Japan Poultry Science Assoc, 2016)
The present study in Japanese quail was aimed to develop multi-trait genetic selection program for a meat type sire line utilizing the mixed-model methodology. In total, 2000 pedigreed quail were formed the basis of the ...
Bayesian Analysis for the Comparison of Nonlinear Regression Model Parameters: an Application to the Growth of Japanese Quail
(Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2016)
This paper discusses the Bayesian approach as an alternative to the classical analysis of nonlinear models for growth curve data in Japanese quail. A Bayesian nonlinear modeling method is introduced and compared with the ...
