The objective of this study was to characterize Kacang goats (aged 1-2 years) in the highland (group 1) and lowland (group 2) areas of Jambi Province based on their body measurements and body indices.
A total of 320 goats were collected from lowland ( = 160), and highland ( = 160) areas with sex proportions of 80 bucks and 80 does for each area. Eight body measurements and 12 body indices were used to characterize the Kacang goats from different areas.
The research showed that each animal group had one principal component (PC) for body measurements and four PCs for body indices. Thus, the body measurement of rump height (RH) and the body indices of area index, weight index, and thoracic development were suggested as the variables to distinguish the Kacang goats from different areas. However, the canonical correlation (r) value in the study was approximately 0.30 (low). Therefore, about 59.4% (lowland) and 60.6% (highland) of Kacang goats were characterized by the body measurements, and the body indices were indicated approximately 48.8% (lowland) and 61.2% (highland) of Kacang goats. A cluster analysis of the four Kacang populations revealed that Kacang goats in this study were grouped into a first cluster (Kerinci) and a second cluster (Muaro Jambi, Batanghari, and Sungai Penuh).
It is concluded that body measurements and body indices cannot characterize the Kacang goats from lowland and highland areas.
本研究的目的是根据加桑山羊（1 - 2岁）的体尺测量和身体指数，对占碑省高地（第1组）和低地（第2组）地区的加桑山羊进行特征描述。
从低地（ = 160）和高地（ = 160）地区共收集了320只山羊，每个地区的性别比例为80只公羊和80只母羊。使用八项体尺测量和十二项身体指数来描述不同地区的加桑山羊。
研究表明，每个动物组在体尺测量方面有一个主成分（PC），在身体指数方面有四个主成分。因此，建议将臀高（RH）的体尺测量以及面积指数、体重指数和胸部发育的身体指数作为区分不同地区加桑山羊的变量。然而，该研究中的典型相关（r）值约为0.30（较低）。因此，约59.4%（低地）和60.6%（高地）的加桑山羊通过体尺测量来表征，身体指数分别表征了约48.8%（低地）和61.2%（高地）的加桑山羊。对四个加桑种群的聚类分析表明，本研究中的加桑山羊被分为第一类（克林奇）和第二类（穆阿拉占碑、巴唐哈里和双溪槟榔）。
得出的结论是，体尺测量和身体指数无法表征低地和高地地区的加桑山羊。
