Abstract

The Present investigation was carried out to analyse the data on growth and reproductive traits in Large White Yorkshire (LWY) crossbred pigs. A total of 1635 records of two genetic groups i.e. 50% crossbred (n=845) and 75% crossbred (n=790) LWY x Desi, spread over the 16 years (1994 to 2010) were taken from the animals maintained under All India Coordinated Research Project on pigs, at Livestock Farm, JNKVV, Adhartal, Jabalpur (M.P.) At slaughter age, 75% LWY were found to be slightly heavier than the 50% LWY crossbreds. The genetic group and year had significant effect (Pd”0.05) on almost all body weights. A significant year effect (Pd”0.05) was observed for all the traits. Littersize at birth had a significant (Pd”0.05) effect on litter weight at birth.
