Abstract

This experiment was conducted to study the effects of dietary branched-chain amino acid (BCAAs) ratios on growth performance, serum biochemical indices, intestinal development of Youxian partridge male ducks aged from 29 to 63 days, so as to determine the suitable BCAAs ratios. A total of 504 healthy 28-day-old Youxian partridge ducks with nearly body weight were randomly divided into 6 groups with 6 replicates in each group and 14 ducks in each replicate. The total amount of dietary BCAAs remained unchanged and the ratios of leucine (Leu), valine (Val) and isoleucine (Ile) in each group (groups 1 to 6) were 1:0.4 0.3, 1:0.5 0.4, 1:0.6 0.5, 1:0.7 0.6, 1:0.8 0.7 and 1:0.9 0.8, respectively, and the levels of other nutrients remained the same. The experimental period was 35 days. The results showed as followed:1) dietary BCAAs ratios had no significant effect on average daily feed intake (ADFI) of ducks (P>0.05). The final weight and average daily gain (ADG) in group 1 were significantly lower than those in the other five groups (P<0.05). The ratio of feed/gain in group 4 was the lowest and significantly lower than that in groups 1 and 2 (P<0.05). 2) The serum glucose content in groups 4, 5 and 6 was significantly lower than that in groups 1 and 2 (P<0.05). The serum uric acid (UA) content tended to decrease and then increase with the increase of dietary Val and Ile ratio (P<0.05), and the serum UA content in groups 4 was the lowest and significantly lower than that in groups 1, 5 and 6 (P<0.05). The serum triglyceride (TG) content in groups 4 and 5 was significantly lower than that in groups 1 and 2 (P<0.05). The serum free fatty acid (FFA) content in groups 3, 4 and 5 was significantly lower than that in groups 1, 2 and 6 (P<0.05). 3) The weight of unit length and relative weight of duodenum, jejunum and ileum in different dietary BCAAs ratios had no significant effects (P>0.05). In conclusion, when the dietary BCAAs level is 3.76%, the ratio is in the range of 1:0.6:0.5 to 1:0.7:0.6, Youxian partridge ducks at 29 to 63 days of age has better growth performance and serum biochemical indices.
