Abstract

The aim of this study was conducted to investigate the effects of methionine in low protein diet on growth performance and serum biochemical indices of sika deer fawns. Twenty-four healthy young sika deer fawns were selected and randomly divided into 3 groups (groups Ⅰ, Ⅱ and Ⅲ) with 8 replicates per group and 1 deer per replicate. The deer in group Ⅰ were fed a diet with 14.16% protein level, those in group Ⅱ were fed a low protein (protein level was 12.46%) diet with 0.16% methionine, and those in group Ⅲ were fed a low protein (protein level was 12.46%) diet with 0.12% methionine. The feeding trial began in October 2, 2015 and ended in October 24, 2015. In order to determine the growth performance, the deer were weighed at the beginning and the end of the experiment; blood samples were collected at the end of the experiment to determine the serum biochemical indices. The results showed that there were no significant differences in weight gain, average daily gain and feed/gain among groups (P>0.05); there were no significant differences in the contents of total protein (TP), globulin (GLOB), urea nitrogen (UN), glucose (GLU) and the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (AKP) in serum among groups (P>0.05), but serum albumin (ALB) content in group Ⅲ was significantly higher than that in group Ⅰ (P<0.05). In conclusion, compare with the diet with 14.16% protein level, the addition of 0.16% methionine to the low protein diet with protein level of 12.46% has no significant effects on the growth performance and serum biochemical indices of sika deer fawns which explained that it is feasible to use the low protein diet with methionine to replace the high protein diet.

Key words： sika deer; growth performance; serum biochemical indices; feed/gain
