中国美利奴羊(新疆型)羔羊断乳体重校正系数的制定

计算出羔羊断乳日龄与断乳体重的相关系数为0．337(呈中度正相关)和回归方程,将羔羊日龄按顺序5 d一组取组限中数代入回归方程,得断乳体重理论值,并导出各组的校正系数;同时,计算周岁羊日龄与体重、产毛量及毛长度的相关系数,并进行了初步分析。

Formation of correction Factor for Lamb's Weanling Body Weight of Chinese Merino (Xinjiang Type)

The correlation coefficient and regressin equation of Lamb's weanling day age and weanling body weight were calculated, in which correlation coefficient was 0. 337. Selected the median within the group of 5d according to lamb's different ages and put the median into the regression equation,thus the theoretical value of weanling body weight lods got. Also the correction factor of groups was educed; the correlation coefficient of "one year old"Merino's day age and body weight, cashmere yield and wool length was calculated simultaneously,in additiom,initial analysis was carried ut in this paper.
