Abstract

Weight deviation groupings were investigated for growth performance, digestibility and carcass characteristics in pigs. One hundred twenty crossbred pigs (Landrace × Yorkshire) of similar age were assigned to 3 treatments groups based on body weight with 4 replications having 10 pigs per replication for 10 weeks. The treatment groups were- 1) MW= Mixed weight group of heterogeneous high and low weight pigs, 2) HW = High weight group of homogeneous high weight pigs and 3) LW = Low weight group of homogeneous low weight pigs. Results revealed that body weight gain was higher (p<0.05) in the homogeneous group (HW and LW) compared to heterogeneous group (MW), however, feed intake and feed efficiency was statistically not different. Higher aggressive behavior was found among the individuals of heterogeneous group compared to homogeneous group. In addition, digestibility of DM of homogeneous group showed higher value (p<0.05) compared to heterogeneous group (MW) while digestibility of nitrogen was not significantly differed. Furthermore, warm carcass weight, dressing percentage and back fat thickness was significantly higher (p<0.05)in homogeneous group (HW and LW) compared to heterogeneous group (HW).Better carcass quality and yield grade was found in case of homogeneous group but there were no significant differences among weight groups. Economic analysis indicated that per unit of body weight gain of homogeneous group was better than the heterogeneous group (p<0.05). In conclusion, weight grouping might be applicable for better management for obtaining uniform slaughter weight group, better growth and carcass characteristics, and ensure animal welfare.

Keywords: Body weight, Carcass quality, Digestibility, Economy, Growth performance, Pig.
