A study was carried out in 30 large White Yorkshire piglets to find out the effect of early and split weaningon carcass characteristics. Four weaning age groups, 56 days of conventional weaning age as group1 (n=8), early weaning of entire litter at 28 days as group 2 (n=10), split weaned piglets with heavylitter weaned at 28 days as group 3 (n=6), weak litter left with sow up to 56 days as group 4 (n=6) werecompared. By the end of study period, pigs were slaughtered and the carcass traits were studied thatincluded dressing percentage and meat: bone ratio. The dressing percent was significantly lower in 2ndgroup of piglets (73.29±0.51) compared to 1st (78.14±0.91), 3rd (76.49±0.53) and 4th (77.91±0.25) group.However no significant difference in dressing percent was observed among 1st, 3rd and 4th group piglets.The meat: bone ratio was significantly higher in 3rd group of piglets (3.20±0.02) compared to 1st (3.07±0.06),2nd (3.03±0.05) and 4th (2.80±0.05)
