Abstract

|
This study was conducted to investigate the effect of feeding RFW (recycled food waste) on performance in growing-finishing pigs. Four treatments with 3 RFW levels were tried in this study; 0% PT (pellet containing 0% RFW), 30% MT (mash containing 30% RFW), 30% PT (pellet containing 30% RFW) and 50% PT (pellet containing 50% RFW). For feeding trials, 60 heads of cross-bred barrows (Duroc x Landrace: average live weight 30 ㎏) were employed to 4 treatments with s replicates of 3 pigs each. For metabolic trials, 12 cross-bred barrows (average live weight 68 ㎏) were used with 3 replicates. The results obtained are as followings;
ADG of 50% PT was significantly (P $lt; 0.05) lower than 0% PT and 30% PT, but 30% MT and 30% PT were not significantly different from 0% PT. In F/G ratio, 2.97 of 30% PT was not (P $gt; 0.05) significantly different from 2.85 of 0% PT treatment. Dressing percentage and back fat thickness were not significantly different among treatment. Addition of RFW increased appearance rate of carcass grade A or B. Nutrient digestibility was decreased by increasing RFW levels. The 30% PT was not significantly different from 0% PT in both DE and digestibility of crude fat and crude fiber, but significantly less in digestibility of crude protein and crude ash (P $lt; 0.05). Economic analysis based on feed cost per weight gain showed that pelleting feed with food waste 30% was the most economical.
