用典型相关分析评价南非非描述性山羊幼山羊出生和断奶时某些生长性状之间的关系

通讯作者:南非林波波大学农业经济与动物生产系农业与环境科学学院Thobela Louis Tyasi, Private Bag X1106, Sovenga 0727, Limpopo, South Africa Email: louis.tyasi@ul.ac.za摘要:本研究评估了6个不同生长性状之间的相关性，即:X:出生体重(BW)、胸围(HG)、臀高(RH)、胸骨高度(SH)、体长(BL)、肩高(WH)，在出生和出生时评估;Y在50只(n = 50)非描述性山羊幼山羊中测量的断奶时胸围(HG_3)、体长(BL_3)、臀高(RH_3)、断奶体重(WW)、肩隆高度(WH_3)、胸骨高度(SH_3)。采用Pearson相关和典型相关分析，Pearson结果显示体重与WW (r = 0.85**)、WH_3 (r = 0.61**)、SH_3 (r = 0.83**)呈高度正相关，P < 0.01。典型相关结果显示，在第一对典型变量中，估计的典型相关系数(r = 0.881)显著(P < 0.01)。结果表明，WH和HG在出生时对典型相关估计的解释能力贡献较大，而BL_3和RH_3在断奶时贡献最大。研究结果表明，出生时的心脏周长和肩胛骨高度可以作为非描述性山羊幼崽选择遗传改进的标准。

期刊介绍： American Journal of Animal and Veterinary Sciences, a quarterly, peer reviewed publication and is dedicated for publication of research articles in the field of biology of animals and with the scientific understanding of how animals work: from the physiology and biochemistry of tissues and major organ systems down to the structure and function of bio molecules and cells; particular emphasis would given to the studies of growth, reproduction, nutrition and lactation of farm and companion animals and how these processes may be optimized to improve animal re- productivity, health and welfare. Articles in support areas, such as genetics, soils, agricultural economics and marketing, legal aspects and the environment also are encouraged. AJAVS is an important source of researcher to study articles on protection of animal production practices, herd health and monitoring the spread of disease and prevention in both domestic and wild animals.
