Abstract

Two experiments were conducted to investigate the effect of different lupin kernel levels on growth performance and carcass characteristics of growing and finishing pigs. In experiment 1, a total of 54 barrows and 54 growing gilts, with an average initial body weight of $24.7{\pm}0.38kg$, was used to determine the effect of different lupin kernel levels (0, 10% and 20%; Control, LK10 and LK20, respectively) in the diets on growth performance with a $3{\times}3$ randomized complete block design for 35 days. There were no significant differences in average daily gain (ADG), average daily feed intake (ADFI) and feed:gain among treatments. In experiment 2, a total of 54 barrows and 36 finishing gilts, with an average initial body weight of $63.0{\pm}0.56kg$, was used to determine the effect of different lupin kernel levels (0, 15% and 30%; Control, LK15 and LK30, respectively) in the diets on growth performance and carcass characteristics with a $3{\times}3$ randomized complete block design for 63 days. LK30 decreased ADG and ADFI compared with the Control and LK15 (p<0.05). However, LK30 tended to improve feed:gain compared with the Control and LK15. And LK15 did not differ from the Control in ADG, ADFI and feed:gain. With inclusion of lupin kernel in the finishing diet, backfat thickness increased (p<0.01) and carcass grade tended to be improved compared with the Control.
