利用退耕还草地和退耕还林地种植青饲玉米,一年生黑麦草、多年生黑麦草、紫花苜蓿、红豆草、三叶草及菊苣等优良牧草,并合理利用种植的牧草资源,舍饲良种山羊,可获得显著的经济效益、社会效益和生态效益。金堂黑山羊属地方优良品种,在我州海拔1500-2200米地区均具有良好的适应性和较强的抗病力,其繁殖力尤为突出,年繁殖力可达200%-900%,平均为326.53%,羔羊成活率79.22%,繁殖成活率为258.68%;生长性能良好,18月龄阉羊胴体重达到28.76±2.9公斤,屠宰率达49.76%。借鉴国内外养羊先进适用技术,建立的《山羊圈养技术规范》,切合我州半农半牧区生态条件和畜牧业生产实际,具有很强适用性、可操作性,属山羊舍饲的适用配套技术。按照20+1的组合模式,建立圈养山羊示范户52户;辐射带动圈养山羊户734户。项目已获得经济效益557.31万元,还可获得经济效益1685.21万元,年平均经济效益为280.32万元,年投资收益率为97.62%。
The use of forage grass, green perennial ryegrass, perennial ryegrass, alfalfa, sainfoin, clover and chicory in the conversion of cropland to grassland and conversion of cropland to pasture, Economic, social and ecological benefits. Jintang black goat is a fine local varieties, in my area of 1500-2200 meters above sea level has a good adaptability and strong resistance, its fecundity is particularly prominent, the annual fecundity of up to 200% -900%, with an average of 326.53%, the survival rate of lamb was 79.22%, the reproductive survival rate was 258.68%. The growth performance was good. The weight of the 18-month-old gelding reached 28.76 ± 2.9 kg and the slaughter rate was 49.76%. Drawing on the advanced and applicable technology of sheep raising at home and abroad, the “Technical Specification for Goat Captivity” meets the requirements of ecological conditions and livestock production in semi-agricultural and semi-pastoral areas in our country and has strong adaptability and maneuverability. technology. In accordance with the 20 + 1 combination model, the establishment of captive goat demonstration households 52 households; radiation led captive goats 734 households. The project has obtained an economic benefit of RMB5,573,100 and an economic benefit of RMB16,852,100, with an annual average economic benefit of RMB2,803,200 and an annual investment rate of return of 97.62%.
