Abstract

Abstract: This study compared effects of tow group sizes(20 pigs per peng and 10 pigs per peng, body weight from 17 to 40 kg) and tow feeding methods(free feeding vs rationed feeding, both 10 pigs peng, body weight from 34 to 60 kg) in a 40 days period, each involving 60 Seghers hybrid pigs. For the pigs raised in large group size(20 pigs per peng) and that raised in small group size(10 pigs per peng), the formers’ growth rate declined 4.95% (P>0.05), their daily feed intake decreases 9.72% (P>0.05), their feed conversion efficiency increases 5.45% (P> 0.05), and they were given gross profit reduction of 0.14 yuan per pig. For the pigs raised by free feeding and that raised by rationed feeding, the formers’growth rate rised 13.3% (P<0.05), their daily feed intake increased 16.87% (P<0.05), their feed conversion efficiency declined 3.14% (P> 0.05), they were given gross profit increase of 11.31 yuan per pig.

Key words: pig; large group size; free feeding; growth performance
