The purpose of this experiment was to evaluate 4 varieties of feed rice brown rice (Liangyouzao 17, Zhongzao 39, Luliangyou 996 and Xiangzaoxian 44) to determine digestible energy (DE) and metabolic energy (ME), and the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of amino acids for growing pigs. In experiment 1: the evaluation of available energy. Ten growing barrows with the similar age and body weight [(25.86±4.81) kg] were housed individually in metabolism cages were selected. The experiment was design by an 5×3 Youden square. Pigs were divided into 2 blocks according to body weight and 5 pigs in each block were used. Using corn-based diet as a basal diet, and experiment diets were formulated by all substitution method using different varieties of feed rice brown rice to replace corn in the basal diet. The trial lasted for 30 days. In experiment 2: the evaluation of amino acid digestibility for growing pigs. Twelve growing barrows with the similar age and body weight [(20.04±3.74) kg] with a T-cannula in the distal ileum divided into 2 blocks according to body weight, 6 pigs in each block, designed by an 6×3 Youden square. A nitrogen-free diet and 5 diets that contained corn and four rice varieties (Liangyouzao 17, Zhongzao 39, Luliangyou 996 and Xiangzaoxian 44) as the sole source of amino acid were formulated. The trial period was 21 days. The results showed as follows: 1) The apparent digestibility of gross energy was no significant difference among four varieties feed rice brown rice and corn (P>0.05). The DE of Liangyouzao 17, Zhongzao 39, Luliangyou 996 and Xiangzaoxian 44 feed rice brown rice for growing pigs was 14.45, 14.42, 14.13 and 14.16 MJ/kg, and the ME was 13.83, 13.87, 13.46 and 13.49 MJ/kg, respectively . There were no significant differences in DE and ME among four varieties feed rice brown rice and corn (DE:14.49 MJ/kg;ME:13.81 MJ/kg) (P>0.05). 2) The AID of isoleucine, leucine, lysine, threonine, valine and alanine of four varieties feed rice brown rice for growing pigs was significantly higher than that of corn (P<0.05); the SID of isoleucine, leucine, lysine, phenylalanine, threonine, valine and alanine of four varieties feed rice brown rice for growing pigs was significantly higher than that of corn (P<0.05). In summary, from the comparison of effective energy value and amino acid digestibility, the four kinds of feed rice brown rice have the potential to replace corn as an energy feed material for growing pigs, thereby reducing dependence on corn.
