Abstract

1. The following research evaluated and compared estimates of genetic parameters of productive and welfare traits of quail in collective cages, testing for inclusion of indirect genetic effects (IGE).2. Data came from two trials, along two generations of pedigreed quail, housed in collective cages, with one male and three females in each cage. Each bird's body weight variation, survival time, aggressiveness, pecking wounds and any feather damage was recorded.3. Three mixed models were tested to obtain genetic parameters. The first was a classical model with no IGE, the second included IGE and the last modelling cage effect was random.4. Heritability estimates were of low magnitude ranging from 0.03 to 0.15, except for survival time, which reached 0.34. Including IGE results in variance redistribution for all traits and heritable variance increases exceeding the value of unity and IGE accounted for most of the heritable variance. Therefore, including these effects is recommended in genetic analysis under collective housing.

集体笼鹌鹑福利性状的遗传参数。

1. 下面的研究评估和比较了集体笼中鹌鹑生产和福利性状的遗传参数估计，并测试了间接遗传效应（IGE）。数据来自两项试验，研究对象是两代纯种鹌鹑，它们被关在集体笼子里，每个笼子里有一只雄性和三只雌性。记录了每只鸟的体重变化、生存时间、攻击性、啄伤和羽毛损伤情况。对三种混合模型进行了测试，以获得遗传参数。第1组为不含IGE的经典模型，第2组为含IGE模型，最后1组为随机笼效应模型。遗传力估计在0.03 ~ 0.15之间，但生存时间达到0.34。添加IGE导致所有性状的方差重新分布，遗传方差增加超过一值，IGE占遗传方差的大部分。因此，建议在集体住房的遗传分析中包括这些影响。

期刊介绍： From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
