Effects of Dietary Arginine Supplemental Level on Performance, Nutrient Digestibility and Nitrogen Metabolism of Female Blue Foxes during Fur Development Period
摘要
Abstract
This experiment was conducted to investigate the effects of dietary arginine supplemental level on performance, nutrient digestibility and nitrogen metabolism of female blue foxes in fur development period. Sixty female blue foxes aged 120 days with similar body weight were randomly divided into 6 groups with 10 replicates per group and 1 fox per replicate. Six groups were fed basic diets supplemented with 0 ( group Ⅰ) , 0.2% ( groupⅡ) , 0.4% ( groupⅢ) , 0.6% ( groupⅣ) , 0.8% ( groupⅤ) and 1.0% ( groupⅥ) arginine, respectively. The pretest period lasted for 7 days and the trial period lasted for 80 days. The results showed as follows:1) the average daily gain of blue foxes in group Ⅳ was significantly higher than that in other groups ( P<0.01) , the body length and fur length in groupⅣwere increased 1.42% and 1.26% compared with groupⅠ ( P>0.05) , the feed to gain in groupⅣwas significantly lower than that in groupⅠ( P<0.01) . The aver-age daily feed intake of blue foxes in groupⅢwas significantly lower than that in groupⅠ( P<0.05) . 2) Di-etary arginine supplemental level had significant effect on fat digestibility of blue foxes ( P<0.01) , and the fat digestibility was increased with the increasing of dietary supplemental level. The dry matter digestibility in group Ⅳ was significantly higher than that in groups Ⅰ, Ⅱ and Ⅲ( P<0.01) . Dietary arginine supplemental level had no effects on protein digestibility and carbohydrate digestibility ( P>0.05) . 3) The nitrogen intake of blue foxes in group Ⅲ was significantly lower than that in other groups except group Ⅳ ( P<0.05) . The con-tent of fecal nitrogen and urea nitrogen in group Ⅳ was the lowest, however, the nitrogen retention, net pro-tein utilization, biological value of protein and protein efficiency ratio in groupⅣwere the highest. It is includ-ed that diet supplemented with 0.6% arginine ( dietary total arginine level is 2.04%) can promote average daily gain and reduce feed to gain for female blue foxes during fur development period.关键词
