Abstract

This study was conducted to investigate the effects of dietary crude protein level and amino acid balance on growth performance, carcass traits and meat quality of finishing pigs. A total of 125 Durco×Landrace×Large White barrows with an average initial body weight of (69.3±3.6) kg were assigned into 5 groups with 5 replicates per group and each replicate had 5 borrows. The five groups were as follows:high protein diet group with about 14% crude protein in diet, low protein with about 10% crude protein-balanced amino acid diet group, and three low protein with about 10% crude protein-unbalanced amino acid diet groups with the ratio of sulfur-containing amino acids, threonine and tryptophan to lysine 10% lower compared with the low protein-balanced amino acid diet group, respectively. The standard ileal digestible lysine (SID Lys) levels of all diets were set at 0.71%, and the ratios of standard ileal digestible threonine (SID Thr), standard ileal digestible sulphur amino acid (SID SAA) and standard ileal digestible tryptophan (SID Trp) to SID Lys in the low protein-balanced amino acid diet group were 0.67, 0.60 and 0.20, respectively. The experiment lasted for 28 days. The results showed that, compared with the low protein-balanced amino acid diet group, a tendency of decrease of the average daily feed intake was found in high protein diet group (P=0.05), and significant decreases of the average daily gain and average daily feed intake were found in the low protein-tryptophan diet group (P<0.05), while neither significant difference was found in the low protein-threonine diet group nor the low protein-sulphur amino acid diet group (P>0.05). Dietary crude protein level and amino acid balance had no significant influences on the carcass traits and meat quality of finishing pigs (P>0.05). The results indicate that the low protein-balanced amino acid diet has no adverse effects on growth performance, carcass traits and meat quality of finishing pigs, and 10% lower of SID SAA, SID Thr and SID Trp have no significant influences on the carcass traits and meat quality of finishing pigs, but 10% lower of SID Trp significant decreases the average daily weight and average daily feed intake of finishing pigs.

Key words： low protein diet; amino acid balance; growth performance; carcass traits; meat quality
