[Studies of the correlations between DNA fingerprints and meat production traits in chickens].
This study revealed correlations between DNA fingerprints (DFPs) and slaughter traits of SR92A male x Xiaoshan female hybrids with EAV (endogenous avian retroviral element) as the probe. In the DFP patterns, the band J with molecular weight of about 4 kilobasepairs correlated significantly with alive weight, dressing weight, semi-eviscerated weight, talon weight, breast muscle weight, head weight and thigh weight. The mean alive weight, dressing weight, semi-eviscerated weight and breast muscle weight are 280 g (28.57%), 225 g (28.87%), 216 g (28.76%) and 16.71 g (54.00%) higher respectively in individuals without band J than in those with band J. With the following formula: delta W = (XJ(-) - XJ+) x N x FJ+, it was estimated that an addition of 165.2 kilograms of alive weight can be achieved in a hybrid population with size of 1,000 chickens established by selecting parents without band J.
