摘要:

为分析日粮中添加不同水平的芦苇对育肥期和田羊生长性能及表观消化率的影响,本研究选取75只6月龄、体重为(30.59±3.36)kg的和田羊,采用单因素完全随机试验设计,随机分为0、10%、20%、30%和40%芦苇水平,每组15只,试验期75 d。结果发现,20%和40%芦苇添加组的干物质采食量均极显著高于对照组(P< 0.01);20%芦苇添加组的日增重显著高于对照组(P< 0.05),10%、30%和40%芦苇添加组的日增重分别比对照组高出10.09%、5.64%和10.87%,但差异不显著(P> 0.05);20%芦苇添加组的干物质、粗蛋白质、粗脂肪、中性洗涤纤维、酸性洗涤纤维、粗灰分、钙和磷的表观消化率均较高;各组的饲料单位成本与饲料总成本随着芦苇添加量的增加而增加,芦苇添加组的增重收益均高于对照组,10%芦苇添加组的经济效益最高。结果表明,日粮中添加20%芦苇时干物质采食量、日增重及干物质、粗蛋白质、粗脂肪的表观消化率均较好;考虑到饲料投入成本,日粮中添加10%芦苇经济效益最高。

Abstract:

In order to investigate the growth performance and apparent digestibility of Hetian sheep in fattening period response to adding reed in diet. Seventy-five Hetian sheep with 6 months old and body weight(30.59 kg±3.36 kg) were classified into 5 groups by single-factor completely random design of experiment, fifteen sheep were assigned to 0, 10%, 20%, 30% and 40% reed addition group. Each group was fed difference diet during the experimental period (75 d). The results showed that the DM intake of 20% and 40% reed addition groups were extremely significant higher than control group (P< 0.01), respectively. The daily gain of 20% reed addition group was significantly higher than control group (P< 0.05), the daily gain of 10%, 30% and 40% reed addition groups were higher than control group 10.09%, 5.64% and 10.87% (P> 0.05), respectively. The apparent digestibility of DM, CP, EE, NDF, ADF, crude ash, calcium and phosphorus in 20% reed addition group was relatively high. Each feed unit cost and total cost would be increase when the reed content of diet increase, the reed addition groups had a better weight gains economic efficiency than control group, and the 10% reed addition group was the best. The results suggested that the DM intake, daily gain and apparent digestibility of DM, CP and EE were better when the diet adding 20% reed. Considering that feed total cost, there were a better economic benefit when the diet adding 10% reed.

Key words: reed; Hetian sheep; growth performance; apparent digestibility; economic benefits
