2015/7/3
Genetic evaluation of length of functional productive life was carried out using a Weibull proportional hazard sire-maternal grandsire model. The database included 405 624 Holstein cows with 19.24% ce...
Estimation of genetic parameters of reproductive traits in Zandi sheep using linear and threshold models
reproductive traits genetic parameters
font style='font-size:12px;'>
2015/6/23
Genetic parameters were estimated for four basic and two composite traits. Year of lambing
