摘要
为进一步提高贵州美酒河流域白酒糟饲料资源有效开发利用程度,在前期研究结果的基础上,试验将其加工成全混合颗粒饲粮(占比30%),研究其对黔北麻羊断奶羔羊生长性能和血浆生化指标的影响。采用t-配对试验设计,将体况良好、体重相近的24只黔北麻羊羔羊分为2组:对照组、试验组,每组3个重复,每个重复4只羊。对照组饲喂人工精粗混匀饲粮;试验组饲喂白酒糟全混合颗粒饲粮,白酒糟占比为30%。试验期共70 d:预饲期10 d,正式期60 d。测定指标包括干物质采食量(DMI)、平均净增重(ANG)、平均日增重(ADG)、料重比(F/G),干物质消化率、粗蛋白消化率、粗灰分消化率,血浆葡萄糖(Glu)、尿素氮(UN)、总蛋白(TP)、白蛋白(Alb)、甘油三酯(TG)、肌酐(Cr)。结果显示:(1)试验组DMI、ANG、ADG显著高于对照组(P<0.05);相应地,F/G显著低于对照组(P<0.05)。(2)试验组DM、CP消化率显著高于对照组(P<0.05);Ash消化率未达显著差异水平(P>0.05)。(3)2组间血浆指标差异均不显著(P>0.05)。这说明,饲喂白酒糟(占比30%)全混合颗粒饲粮,可显著提高黔北麻羊断奶羔羊生长性能,对血浆生化指标没有显著影响。由此可见,白酒糟是有益的饲料资源,值得开发利用。
This study was conducted to evaluate the effect of total mixture ration pelleted with distill- errs grains on growth performance and plasma biochemical indices of weaned lambs for improvement of distiller＇ grains efficiency. Twenty-four healthy lambs with similar body condition were randomly allocated to 2 groups with 3 replicates per group and 4 lamb per replicate： control, treatment. Lambs in the control were fed the artificially mixed diet with concentrate and roughage. Lambs in the treatment were fed total mixture ration pelleted with distiller＇s grains at 30% level. The experiment last 70 days with 10-day prefeeding and 60-day trial durations. Dry matter intake （DMI）, average net gain （ANG）, average daily gain （ADG）, ratio of feed to gain （F/G）; apparent digestibility of dry matter, crude protein, and ash; plasma levels of glucose （Glu）, urea nitrogen （UN）, total protein （TP）, albu- min （Alb）, triglyceride （TG） and creatinine （Cr） were detected.① Compared with control, lambs in the treatment had higher DMI, ANG, and ADG; and lower F/G （P〈0.05）.②The apparent digestibility of DM and CP for treatment was higher than control （P〈0.05）, but not for Ash （P〉0.05）.③Plasma metabolites were unaffeeted between the two groups of lambs （P〉0.05）. These results indicated that total mixture ration pelleted with distiller＇s grains （30%） was able to increase growth performance, and had no significant effect on plasma biochemical indexes for Qianbei Ma lambs.
