Abstract:To understand the genetic characteristics of Shanyi colony inbred strain E of Chinese hamster, the reproduction records of Shanyi colony inbred strain E of Chinese hamster in 2001-2010 were used to estimate the heritability of the reproduction traits by the method of average information restricted maximum likelihood (AIREML). The results showed that the heritability of the litter size, weaning number, birth interval 2-1, birth interval 3-2 was low, with the value of 0.5,0.6,0.182 and 0.116, respectively.
