Growth traits data of 361 Nanjiang yellow goats were used to study the genetic and non-genetic effects. The results show that year, season of birth and sex of kids affect the growth traits significantly. It is more accurate to estimate genetic and phenotypic parameters from a hierachical classification model excluding non-genetic deviattion than from a simple paternal half-sib correlation. Heritabilities are 0.18, 0.43, 0.33, 0.18, 0.44 aed 0.39 for weights at birth, weaning, six months and one year, and for...

Growth traits data of 361 Nanjiang yellow goats were used to study the genetic and non-genetic effects. The results show that year, season of birth and sex of kids affect the growth traits significantly. It is more accurate to estimate genetic and phenotypic parameters from a hierachical classification model excluding non-genetic deviattion than from a simple paternal half-sib correlation. Heritabilities are 0.18, 0.43, 0.33, 0.18, 0.44 aed 0.39 for weights at birth, weaning, six months and one year, and for pre-weaning and post-weaninig growth rates respectively. Both genetic and phenotypic correlations are negetive(-0.36 and -0.23) between weight at two months and post-weaning growth rate.

分析361只南江黄羊的生长发育性状的遗传与非遗传效应。结果表明:羔羊出生年度、季节和性别不同对羔羊的生长发育性状的影响明显不同;在估计遗传及表型参数时,建立系统分组模型剔除非遗传效应的父系半同胞法优于简单的父系半同胞法;初生重、二月龄体重、六月龄体重、周岁体重,断奶前日增重、断奶后日增重的遗传力分为0.18、0.43、0.33、0.18、0.44、0.39。二月龄体重与断奶后日增重的遗传及表型相关均为负值(-0.36和-0.23)。

Six Holstein bulls and their 40 mated cows and 40 daughters were selected in this experiment.Cattle blood was sampled both in heat stress and nonheat stress period.The heredity of the potassiumcontent in erythrocytes was determined,and its heredity reliability as a heat tolerant index was examined byother assessing indexes.The potassium content showed a heredity to some extent.Estimates of heritabilitywere 0.248 and 0.387 with regard to the father and mother respectively.Both parents'cooperative heredityis more...

分别在热应激和非热应激期间对6头种公牛和40对母女牛采血,测定红细胞钾的遗传性,并用其他耐热性指标检验红细胞钾作为耐热性选择指标的遗传可靠性。结果,红细胞钾的遗传力,用公牛内半同胞法估计为0.248,用公牛内母女回归法估计为0.387。双亲协同遗传效应较单亲明显。双亲红细胞钾对女儿红细胞钾、直肠温度、呼吸率、血红蛋白、皮质醇和产奶量均有一定影响,红细胞钾作为耐热性选择指标是可靠的。

Heretabilities were est imated from correlation between relatives of the mixed family for eggproduction in New Yangzhou chickens. Genetic correlations between traits were derived from sire componentsof variance in the half─sib analyses. Meantime, 4 selection indexes were calculated using b=P ̄(-1) GW.Heri-tabillty of age at first egg(AFG),number of egg to 300 days old(NE-300d),egg weight(EW)and num-ber of egg to 500 days old(NE-500d) were 0. 28,0.19,0. 58,0. 24,respectively.
