Effects of Dietary L-Arginine Content on Amino Acid Digestibility, Serum Amino Acid Contents and Serum Biochemical Indices of Female Mink in the Winter Fur-Growing Period
摘要
Abstract
This study was conducted to study the effects of dietary L-arginine content on amino acid digestibili-ty, serum amino acid contents and serum biochemical indices of female mink in the winter fur-growing period. Sixty-three healthy female mink at the age of ( 150 ±3) days were randomly divided into 7 groups with 9 repli-cates each and 1 mink per replicate.The mink in the seven groups were fed experimental diets with L-arginine supplemental levels of 0, 0.20%, 0.40%, 0.60%, 0.80%, 1.00%and 1.20%, and the L-arginine content in the experimental diets were 1.70%, 1.90%, 2.10%, 2.30%, 2.50%, 2.70%and 2.90%, respectively.The pre-test period lasted for 7 days, and the trial lasted for 60 days.The results showed as follows: 1 ) the dry matter ( DM) intake, DM output and DM digestibility had no significant difference among all groups ( P>0.05) .2) The digestibility of lysine in 1.70%group were significantly higher than those in 2.50%, 2.70%and 2.90%groups ( P<0.05) .The digestibility of arginine in 2.70%and 2.90%groups was significantly high-er than that in 1.70%and 1.90%groups (P<0.05).3) The contents of serum proline and serine in 2.30%group was significantly higher than that in 1.70%, 1.90%, 2.10%and 2.90%groups ( P<0.05) .The content of serum alanine in 2.30%and 2.50%groups was significantly higher than that in 1.70%, 1.90%, 2.10%and 2.90%groups ( P<0.05) .The content of serum phenylalanine in 2.30%group was significantly higher than that in 1.70%and 2.90%groups ( P<0.05) .The content of serum arginine in 2.30%group was significantly higher than that in 1.70%, 1.90%, 2.10%and 2.90%groups ( P<0.05) .4) The activity of serum aspartate amino transferase in 2.30%group was significantly higher than that in 1.70%group ( P<0.05) .The activity of serum lactate dehydrogenase in 2.30%and 2.50%groups was significantly higher than that in 1.70%, 1.90%, 2.10%, 2.70%and 2.90%groups (P<0.05).5) The content of serum immunoglobulin M in 2.30%and 2.50%groups was significantly higher than that in 1.70%, 1.90%, 2.10%, 2.70%and 2.90%groups ( P<0.05) .The content of serum immunoglobulin G in 2.30%group was significantly higher than that in 1.70%and 2.90%groups ( P<0.05) .The content of serum complement 4 in 2.30%and 2.50%groups was signifi-cantly higher than that in 1.70%and 2.90%groups (P<0.05), and the content of serum complement 4 in 2.10%group was significantly higher than that in 1.70%group (P<0.05).So, when the dietary L-arginine content is 2.30%, the female mink in the winter fur-growing period can obtain better protein and amino acid metabolism, and enhance the immune function.关键词
