摘要

本试验旨在研究饲粮中添加不同豆科草本植物对肥尾羔羊采食量、消化率和活重的影响。选取24只8月龄、初始活重12.73±0.56 kg (SE)的公肥尾羔羊,根据未禁食活重随机分为4个处理组。动物被关在单独的新陈代谢箱里。试验采用完全随机区组设计,设4个处理,6个重复。试验饲粮处理包括:穆拉多随意草(M)、M+ pascuorum Centrosema (MCP)、M+ Dolichos lab lab (MDL)和M+阴蒂(MCT)。所有补充剂均以每日1.5%体重(W)提供。试验期10周,预试期2周,测量期8周。测定的主要参数包括采食量、饲料消化率和平均日增重。结果表明:饲粮中添加豆科草本植物对饲粮总干物质摄入量(DMI)无显著影响(P < 0.05)。MCP、MDL和MCT处理的总DMI分别为2.75%、2.79%、2.84%和2.87% W/d。相比之下,添加各种豆科草药显著提高了豆科草药间的肥力(p0.05)。饲料DMD分别为58.17、67.48、64.91;65.03%,平均日增重35.67;58.39;M、MCP、MDL和MCT处理分别为54.31和54.41 g/d。综上所述,饲粮中添加豆科草本植物显著提高了穆拉多草肥尾羊的DMD和ADG,但不同饲粮中添加豆科草本植物差异不显著。

The Effect of Various Legume Herbs Supplementation on Intake, Digestibility and Growth of Fat-tailed Lambs Given Mulato Grass
This experiment was conducted to examine the effect of various legume herbs supplementation on feed intake, digestibility and liveweight gain of fat-tailed lambs given Mulato ( Brachiaria mulato ) grass. Twenty four male fat-tailed lambs (8 months of age and 12.73± 0.56 kg (SE) of initial liveweight) were randomly allotted to four treatment groups based on unfasted liveweight.  Animals were housed in individual metabolism crates. The experiment was designed in a completely randomized block design, with four treatments and six replicates. The dietary treatment tested included Mulato grass ad libitum (M), M + Centrosema pascuorum  (MCP), M + Dolichos lab lab (MDL) and M+ Clitoria ternatea (MCT). All supplement was offered at 1.5% body weight (W) per day.  The experiment lasted for 10 weeks, with 2 and 8 weeks for adaptation and measurement period, respectively. The main parameter measured included feed intake, feed digestibility, and average daily liveweight gain (ADG).  Results showed that total DM intakes (DMI) were not affected (P>0.05) by legume herbs supplementation. Total DMI was 2.75, 2.79, 2.84 and 2.87 %W/d for lamb treated with M MCP, MDL and MCT respectively. In contrast, supplementation with various legume herbs significantly increased (P 0.05) between legume herbs.  Feed DMD was 58.17, 67.48, 64.91; 65.03% and ADG were 35.67; 58.39; 54.31 and 54.41 g/day, for lamb treated with M, MCP, MDL and MCT respectively. It was concluded that supplementation of legume herbs to fat-tailed lamb fed Mulato grass significantly increased DMD and ADG, but no significant differences across the legume herbs as feed supplements were observed.
