Effect Of Swill Feeding On The Reproductive Performance Of Large White Yorkshire Pigs

Abstract

An experiment was conducted to find out the effect of swill feeding on reproductive performance of pigs. A total of sixteen Large White Yorkshire weaned female piglets ( 56 days) were selected at random and were divided into two groups consisting of eight piglets in each group and they were subjected to different feeding regimens viz., 100 per cent concentrate (T1 ) and the same was replaced on DM basis with hostel food waste at 50 per cent level (T2). The overall weight gain and average daily gain was significantly (P<0.01) higher from weaning to one year of age in T2 when compared to T1. But the feed conversion efficiency was better in T1 than the T2 . The mean litter size at birth and weaning were higher in T2 compared to T1. Similarly, the gilts fed with 50 % swill feed (T2) produced piglets with significantly (P<0.01) higher birth weight and weaning weight than the 100 % concentrate fed group. The gestational weight gain and lactational weight loss were significantly (P<0.01) higher in T2 compared to T1.
