【摘要】：為分析日糧中添加不同水平的蘆葦對育肥期和田羊生長性能及表觀消化率的影響,本研究選取75只6月齡、體重為(30.59±3.36)kg的和田羊,采用單因素完全隨機試驗設計,隨機分為0、10%、20%、30%和40%蘆葦水平,每組15只,試驗期75d。結果發(fā)現,20%和40%蘆葦添加組的干物質采食量均極顯著高于對照組(P0.01);20%蘆葦添加組的日增重顯著高于對照組(P0.05),10%、30%和40%蘆葦添加組的日增重分別比對照組高出10.09%、5.64%和10.87%,但差異不顯著(P0.05);20%蘆葦添加組的干物質、粗蛋白質、粗脂肪、中性洗滌纖維、酸性洗滌纖維、粗灰分、鈣和磷的表觀消化率均較高;各組的飼料單位成本與飼料總成本隨著蘆葦添加量的增加而增加,蘆葦添加組的增重收益均高于對照組,10%蘆葦添加組的經濟效益最高。結果表明,日糧中添加20%蘆葦時干物質采食量、日增重及干物質、粗蛋白質、粗脂肪的表觀消化率均較好;考慮到飼料投入成本,日糧中添加10%蘆葦經濟效益最高。
[Abstract]:In order to analyze the effect of different levels of Reed on growth performance and apparent digestibility of Hetian sheep in fattening period, 75 6 months old Hetian sheep with weight of 30.59 鹵3.36 kg were selected in this study. A single factor complete random trial design was used. It was randomly divided into 0 10% and 20% and 40% Reed levels, 15 in each group, for 75 days. The results showed that there were 15 reeds in each group for 75 days. The dry matter intake of the 20% and 40% Reed supplementation groups were significantly higher than that of the control group (P 0.01). The daily gain of 20% Reed supplementation group was significantly higher than that of the control group P0.0510% and 40% Reed addition group, respectively 10.09% higher than that of the control group. 5.64% and 10.87, but the difference was not significant (P 0.05). The apparent digestibility of dry matter, crude protein, crude fat, neutral detergent fiber, acid detergent fiber, crude ash, calcium and phosphorus were higher in 20% Reed group. The feed unit cost and total feed cost of each group increased with the increase of Reed addition. The weight gain of Reed added group was higher than that of the control group (10% Reed addition). The results showed that the economic benefit of Reed added group was the highest. The apparent digestibility of dry matter intake, daily gain, dry matter, crude protein and crude fat were better when 20% reeds were added to the diet. Considering the feed input cost, the economic benefit of adding 10% reeds to the diet was the highest.

【正文快照】： 蘆葦為多年生禾本科植物,耐旱、耐水淹、耐脊薄、抗熱、抗寒、適應性強,在中國各地均有分布[1-4]。據統計,中國蘆葦分布面積約80萬hm2,其中新疆約6.67萬hm2,按單產4 500kg/hm2計算,總量達30萬t[1]。蘆葦莖葉幼嫩時稍有甜味,為各種家畜所喜食,故其在傳統畜牧業(yè)生產中起到重要的
