ABSTRACT

In this study, SPSS software was used to fit five growth models (Logarithmic, Quadratic, Cubic, S, and logistic) of body weight and body size traits of Alashan Bactrian camel. The results showed that the S growth model of body height, body length, chest circumference and tube circumference had the best fitting effect, and the fitting degree was 0.937, 0.982, 0.972 and 0.914, respectively. The S growth models of body height, body length, chest circumference and tube circumference were Y=e(5.219-0.520/X), Y=e(5.140-0.601/X), Y=e(5.473-0.615/X), Y=e(3.006-0.674/X), respectively. The cubic model and S model of the body weight of Alashan Bactrian camel had the best fitting effect (R2 = 0.979, 0.974), the cubic growth model of the body weight of Alashan Bactrian camel was Y=103.083+128.340X-11.138X2+0.325X3, and the S growth model was Y=e(6.491-1.228/X).
