ABSTRACT
Sprouted rough rice (SR) is not commly used for poultry diets but it could be a potential replacement ingredient to improve nutritional value of feed. This study aimed to evaluate the growth performance, carcass quality, blood lipids, hepatic enzymes, and fatty acid profiles of broiler meat when corn was replaced with sprouted rough rice in the feed. A completely randomized design was used with four groups and six replicate groups with 10 birds per replicate. The 4 treatment groups were 0, 15, 40 and 45 % sprouted-rice-replacement of corn. Growth performance and carcass quality were highest when corn was replaced with 45 % SR (p < 0.05). In particular, live weight and body weight gain increased linearly with increasing SR inclusion, whereas feed conversion ratio and feed intake linearly decreased with increasing SR (p < 0.05). Carcass, thigh, and breast weights showed the same trend of increase (p < 0.05). In addition, the pH of the thigh meat was significantly higher in diet with 45 % SR than in the other treatment groups. With increasing SR content, the weight of immune organs linearly increased, particularly the thymus and spleen (p < 0.05). Additionally, the fatty acids examined including saturated fatty acids, unsaturated fatty acid, transfat were mostly highest when 30 or 45 % of corn was replaced with SR and linearly increased from 0 to 45 % of SR. There were no significant differences of linear relationships with cooking loss, or blood lipid and hepatic enzyme profiles between treatments (p > 0.05). Replacing 45 % of corn in a broiler diet with SR could improve the growth and meat paramenters of broilers.
