摘要

摘要本研究旨在对当地山羊种群进行形态学表征。从3个地区随机选取640只山羊，记录体重和线性体测量值。除穗长和尾长外，其余数量性状均受性别、龄级和农业生态的显著影响(p < 0.05)。低地山羊种群的身体测量值显著高于中部和高地山羊种群。成熟山羊体重、胸围和肩高的总体(LSM±SE)分别为29.13±0.22 kg、71.24±0.20 cm和66.61±0.18 cm。多元回归分析表明，与任何其他线性身体测量相比，心脏围长更能解释体重的变化。因此，体重可以用胸围来预测，do = - 41.6 + 0.99x, bucks = - 44.3 + 1.10x。

Body weight and linear body measurements of indigenous goat population in Awi Zone, Amhara region, Ethiopia

ABSTRACT The study was conducted with the objective of undertaking morphological characterization of indigenous goat population. A total of 640 goats were randomly selected from three districts and body weight and linear body measurements were recorded. All the quantitative traits were significantly (p < 0.05) affected by sex, age classes and agro-ecology except ear length and tail length. The lowland goat population had significantly higher body measurements than midland and highland goat population. The overall (LSM ± SE) of matured goat body weight, heart girth, and height at withers were 29.13 ± 0.22 kg, 71.24 ± 0.20 cm, and 66.61 ± 0.18 cm, respectively. The multiple regression analysis showed that heart girth explained more variation on body weight than any other linear body measurements. Therefore, body weight can be predicted using hearth girth with the equation y = −41.6 + 0.99x for does and y = −44.3 + 1.10x for bucks.
