Abstract: The age as independent variable and body weight as dependent variable was realized curve fitting to Body measurements of Bostaurusdomestica cow, Holstein cow, Simmental cow, Tsigai, the ram and ewe of Tibetan sheep in Tibet agriculture region. The correlation coefficients of curve fitting are 0.83，0.72，0.78，0.68，0.67 and 0.74, respectively. The between measured values and estimated were no significant(P>0.05). The growth characteristics of cows and sheep in Tibet agriculture regions were truly realized in these regression models.

Key words: Bostaurusdomestica; Holstein; Simmental; Tsigai; Tibetan sheep; fitting curve
