摘要

本试验旨在研究饲粮L-精氨酸添加水平对育成期水貂生长性能、营养物质消化率及氮代谢的影响。选取(60±3)日龄健康雌性水貂70只,随机分成7组,每组10个重复,每个重复1只水貂。7组水貂分别饲喂在基础饲粮(L-精氨酸含量为1.45%)基础上添加0(Ⅰ组)、0.2%(Ⅱ组)、0.4%(Ⅲ组)、0.6%(Ⅳ组)、0.8%(Ⅴ组)、1.0%(Ⅵ组)和1.2%(Ⅶ组)L-精氨酸的试验饲粮。预试期7 d,正试期60 d。结果表明:Ⅲ组的末重、平均日增重和料重比高于其他各组,但差异不显著(P>0.05)。Ⅲ组的干物质采食量极显著高于Ⅰ组(P<0.01),显著高于Ⅱ组和Ⅵ组(P<0.05)。Ⅲ组的干物质排出量显著高于Ⅰ组和Ⅳ组(P<0.05)。Ⅳ组的干物质消化率高于其他各组,但差异不显著(P>0.05)。Ⅳ组的蛋白质消化率显著高于Ⅰ组、Ⅱ组、Ⅲ组、Ⅴ组和Ⅶ组(P<0.05)。Ⅳ组的脂肪消化率显著高于Ⅴ组、Ⅵ组和Ⅶ组(P<0.05)。Ⅲ组的食入氮极显著高于Ⅰ组和Ⅱ组(P<0.01),显著高于Ⅴ组和Ⅵ组(P<0.05)。Ⅲ组的粪氮极显著高于Ⅰ组和Ⅳ组(P<0.01)。Ⅲ组的氮沉积极显著高于Ⅰ组和Ⅵ组(P<0.01),显著高于Ⅱ组和Ⅴ组(P<0.05)。Ⅲ组和Ⅳ组的净蛋白质利用率显著高于Ⅰ组(P<0.05)。Ⅲ组和Ⅳ组的蛋白质生物学价值显著高于Ⅰ组(P<0.05)。由此得出,饲粮L-精氨酸添加水平为0.4%~0.6%(L-精氨酸总含量为1.85%~2.05%)时,育成期水貂的生长性能、营养物质消化率、氮沉积、净蛋白质利用率及蛋白质生物学价值较为理想。

Abstract

This study was conducted to study the effects of dietary L-arginine (L-Arg) supplemental level on growth performance, nutrient digestibility and nitrogen metabolism of growing mink. Seventy healthy female mink at the age of 60-day were randomly divided into 7 groups with 10 replicates each and 1 mink per replicate. The mink in 7 groups were fed the basal diet (L-Arg content was 1.45%) supplemented with 0 (group Ⅰ), 0.2% (group Ⅱ), 0.4% (group Ⅲ), 0.6% (group Ⅳ), 0.8% (group Ⅴ), 1.0% (group Ⅵ) and 1.2% (group Ⅶ) L-Arg, respectively. The pre-test period lasted for 7 days and the trial lasted for 60 days. The results showed as follows: the final weight, average daily gain and feed/gain of the group Ⅲ were higher than those of the other groups, but the differences were not significant (P>0.05). The dry matter (DM) intake of the group Ⅲ was extremely significantly higher than that of the group Ⅰ(P<0.01) and it was significantly higher than that of groups Ⅱ and Ⅵ (P<0.05). The DM output of the group Ⅲ was significantly higher than that of groups Ⅰ and Ⅳ (P<0.05). The DM digestibility of the group Ⅳ was higher than that of the other groups, but the difference was not significant (P>0.05). The protein digestibility of the group Ⅳ was significantly higher than that of groups Ⅰ, Ⅱ, Ⅲ, Ⅴ and Ⅶ (P<0.05). The fat digestibility of the group Ⅳ was significantly higher than that of groups Ⅴ, Ⅵ and Ⅶ (P<0.05). Nitrogen intake of the group Ⅲ was extremely significantly higher than that of groups Ⅰ and Ⅱ (P<0.01) and it was significantly higher than that of groups Ⅴ and Ⅵ (P<0.05). The fecal nitrogen of the group Ⅲ was extremely significantly higher than that of groups Ⅰ and Ⅳ (P<0.01). The nitrogen deposition of the group Ⅲ was extremely significantly higher than that of groups Ⅰ and Ⅵ (P<0.01) and it was significantly higher than that of groups Ⅱ and Ⅴ (P<0.05). Net protein utilization of groups Ⅲ and Ⅳ was significantly higher than that of the group Ⅰ (P<0.05). Biological value of protein of groups Ⅲ and Ⅳ was significantly higher than that of the group Ⅰ (P<0.05). In conclusion, when the dietary L-Arg supplemental level is 0.4% to 0.6% (L-Arg total content is 1.85% to 2.05%), the growth performance, nutrient digestibility, nitrogen metabolism, net protein utilization and biological value of protein of growing mink are optimal.
