饲粮锰水平对育成期水貂生长性能及血清生化指标的影响
Effects of Dietary Manganese Level on Growth Performance and Serum Biochemical Indices of Growing Mink
摘要
Abstract
This experiment was conducted to study the effects of dietary manganese ( Mn) level on growth per-formance and serum biochemical indices of growing minks.Seventy-five 60-day-old healthy male minks were randomly divided into 5 groups with 15 replicates per group and 1 mink per replicate.Minks in the 5 groups were fed the experimental diets supplemented with 0 ( group Ⅰ, as control group), 50 ( group Ⅱ), 100 ( group Ⅲ) , 300 ( groupⅣ) and 600 mg/kg ( groupⅤ) Mn based on a basal diet, respectively, and the Mn level in the basal diet was 43.69 mg/kg.There was a 7-day adaptation period and a 60-day experimental peri-od.The results showed as follows: the average daily feed intake was not significantly different among all groups ( P>0.05) .There was no significant difference in average body weight among all groups at 60, 75, 90 and 105 days of age ( P>0.05) , but the highest value of average body weight at the 120 days of age was found in group Ⅳ, and it was significantly higher than that in group Ⅰ ( P<0.05) .The average daily gain ( ADG) in group Ⅳ was significantly higher than that in other groups during 60 to 75, 91 to 105 and 106 to 120 days of age (P<0.05).Dietary Mn level had no significant effects on serum total protein (TP), albumin (ALB), globulin ( GLOB) , immunoglobulin A ( IgA) and immunoglobulin M ( IgM) contents and serum aspartate a-mino transferase ( AST) , alanine amino transferase ( ALT) , alkaline phosphatase ( ALP) activities, and all of them in group Ⅳhad the highest values.The serum urea nitrogen ( UN) content in groupⅣwas significantly lower than that in other groups ( P<0.05) .The serum lactic acid dehydrogenase ( LDH) , total superoxide dis-mutase ( T-SOD) , Mn-superoxide dismutase ( Mn-SOD) activities and serum immunoglobulin G ( IgG) con-tent were not significantly different among all groups ( P>0.05) .Under the conditions of this experiment, diet-ary supplemented with 300 mg/kg Mn and the dietary Mn level is 343.69 mg/kg can improve the growth per-formance of growing mink, it also can improve protein metabolism related index contents, Mn related enzyme activities, and the immunity of mink.关键词
