Title : CARCASS QUALITY OF LANDRACE X DESI PIGS UNDER SPLIT WEANING AND DIFFERENT FEEDING REGEMIES

Abstract :

An experiment conducted to the asses the carcass quality of Landrace X Desi pigs under split weaning and different feeding regime was carried out at Indian Veterinary Research Institute, Izatnagar, Barielly, Utter Pradesh. Eighteen pregnant gilts (62.5% Landrace and 37.5% Desi) were randomly divided into two groups (C and T, respectively) having 9 gilts each. After birth of piglets in control group were allowed to suckle their dams until 56 days of age and kept as control and weaned thereafter. In other half (T), heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining comparatively lighter piglets were weaned at 42 days after birth. Weaned piglets again distributed 3 subgroups with 15 piglets in each group and these piglets were fed with 100% Concentrate ration, 50 Concentrate and 50% Kitchen waste and 100% kitchen waste. The split weaned heavier half piglets (T2) and lighter half (T3) were again distributed 3 subgroups and fed with same as control groups. All the selected animals were housed on similar concrete floored pens provided with separate feeder and water facility with a run area behind. After 12 weeks, 4 males were selected and reared upto 60 ± 5 Kg from each subgroup for studying the carcass traits. Treatments had no significant effect on live weight, carcass weight, carcass length, Bach fat thickness. But significant (P<0.01) effect was observed on dressing percentage and loin eye area. Dressing percentage was highest in T2 (70.56±0.64) compared to T1(67.24±0.74). Loin eye area (sq.cm) was significantly higher in T1 (39.67±1.2). Diet had highly significant (P<0.01) effect on live weight, fasting weight, head, carcass weight, back fat thickness, belly, loin and ham but dressing percentage, carcass length and picnic had significant (P<0.05). Hence, based on the study it is advisable to feed pigs with concentrate and kitchen waste diet to get maximum economic value due to good carcass quality.
