Abstract

Both L-aspartate (L-Asp) and D-aspartate (D-Asp) play important physiological roles in animals. However, there are very few studies available in birds and no reports have been found in broilers. Broilers are very important commercial birds for meat production, so effects of L- or D-Asp in broilers would provide new physiological insight of this strain. Therefore, the purpose of this study was to determine the effect of oral administration of L- or D-Asp on food intake, body temperature and some plasma metabolites in broiler For Peer Review chicks. Broiler chicks were orally administered with different doses (0, 3.75, 7.5 and 15 mmol/kg body weight) of L- or D-Asp. We confirmed that oral administration of both For Peer Review L- and D-Asp did not alter food intake. However, D-Asp, but not L-Asp, For Peer Review dose-dependently decreased the rectal temperature in chicks. It was also found that For Peer Review D-Asp increased plasma glucose and decreased triacylglycerol concentrations. T changes in plasma metabolites further indicate that D-Asp treatment modulates energy metabolism in broiler chicks. In conclusion, D-Asp may be a beneficial n for broilers, since orally administered D-Asp lowered body temperature without reducing food intake.
