Estimation of genetic parameters of reproductive traits in Zandi sheep using linear and threshold models
reproductive traits genetic parameters
2015/6/23
Genetic parameters were estimated for four basic and two composite traits. Year of lambing
and age of ewe were used as fixed effects. Due to repeated record of ewe animal direct genetic effect...
