摘要

本研究旨在探明以青贮甜高粱替代不同比例甜高粱青干草对德州驴驹生长发育的影响。以30头德州驴驹为研究对象,随机分为5组(每组6头),分别将0(对照组)、15%、30%、45%、60%[以干物质(DM)计]的甜高粱干草替代为青贮甜高粱,饲喂60 d后测定其生长性能、营养物质消化率及血清生化指标。结果显示:1)驴驹的平均日增重(ADG)、平均日采食量(ADFI)、料重比(F/G)、总饲喂成本及每千克增重饲喂成本各组间均无显著差异(P>0.05),其中60%组的F/G最低,15%组的每千克增重饲喂成本最低。2)对照组DM和粗蛋白质(CP)消化率最高,酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)消化率最低;30%组粗纤维(CF)消化率最高,45%组粗脂肪(EE)消化率最高;各替代组间仅30%组EE消化率显著低于45%组(P<0.05),其他组间均无显著差异(P>0.05)。3)血清生化指标中,30%组血清白球比(A/G)显著高于45%组(P<0.05);45%组血清白细胞介素-2(IL-2)含量显著低于15%组;60%组血清免疫球蛋白G (IgG)含量显著低于其他各组(P<0.05),且血清甲状腺素(T4)含量显著低于对照组和15%组(P<0.05)。综上所述,青贮甜高粱替代部分甜高粱青干草能够满足驴驹的正常生长发育,无明显负面效应;综合考虑饲喂效果及经济效益,以15%(以DM计)的替代比例为最佳。

Abstract

The aim of this study was conducted to investigate the effects of sweet sorghum hay replacement by different proportions of sweet sorghum silage on the growth and development of Dezhou donkey foals. Thirty Dezhou donkey foals were divided into five groups with 6 donkeys per group. In the five groups, sweet sorghum silage was used to replace 0, 15%, 30%, 45% and 60% dry matter (DM) of sweet sorghum hay, respectively. After 56-day feeding, the growth performance, nutrient digestibility and serum biochemical indexes of these donkeys were measured. The results showed as follows:1) there were no significant differences in average daily gain (ADG), average daily feed intake (ADFI), feed/gain (F/G), total cost of feed and feed cost per kg gain among different groups (P>0.05); when 60% sweet sorghum hay replaced by sweet sorghum silage, the donkeys showed the lowest F/G; as well as the 15% group showed the lowest feed cost per kg gain. 2) The DM and crude protein (CP) digestibility of the control group was the highest, while the ADF and NDF digestibility was the lowest among all groups, as well as the crude fibre (CF) and ether extract (EE) digestibility was the highest in 30% and 45% groups, respectively; the EE digestibility in the 30% group was significantly lower than that in the 45% group (P<0.05). 3) For the serum biochemical indexes, the serum albumin/globulin (A/G) in the 30% group was significantly higher than that in the 45% group (P<0.05); the serum interleukin-2 (IL-2) content in the 45% group was significantly lower than that in the 15% group (P<0.05); the serum immunoglobulin G (IgG) content in the 60% group was significantly lower than that in the other groups (P<0.05), and the serum thyroxine (T4) content was significantly lower than that in the control group and 15% group (P<0.05). In conclusion, replacing the sorghum silage hay partly with sweet sorghum silage can satisfy the normal growth and development of donkey foals, and 15% is the best proportion in comprehensive consideration of feeding effect and economic benefit.
