裹包青贮甜高粱饲喂羔羊育肥效果试验报告

Experimental Study on Fattening Effect of Graping Sweet Sorghum on Lamb

笔者以青贮甜高粱、全贮玉米、全贮玉米秸秆50%+马铃薯粉渣50%为原料,设置3个处理开展裹包青贮甜高粱饲喂羔羊育肥效果试验。结果表明,裹包青贮甜高粱,裹包全贮玉米和3种饲草混合饲喂育肥羔羊平均日增质量分别为0.0963 kg/d、0.1010 kg/d和0.1312 kg/d,用SPSS Statistics 22.0统计软件进行方差分析,育肥效果差异不显著(P>0.05)。但从甜高粱自身经济效益来看,每667 m2(1亩)产鲜草量可达7 t^8 t,较全株玉米产量提高2 t左右。由此来看,甜高粱用于青贮饲料生产,能有效填补定西市肉羊产业发展对优质饲草料的需求。同时,随着甜高粱种植面积的扩大,可以有效降低饲草料成本,增加经济效益。因此,甜高粱在定西市养殖生产中值得大力推广种植。

In this study, three treatments were conducted on sweetened sorghum, whole corn, whole corn stalks 50% ＋ 50% of potato flour. The results showed that the average daily increase of garlic sweet sorghum, wrapped whole corn and three forage mixed feeding lambs were 0.0963 kg/d, 0. 1010 kg/d and 0.1312 kg/d, respectively. Statistics 22.0 statistical software for analysis of variance, fattening effect difference was not significant （P〉0.05）. However, from the economic benefit of sweet sorghum, the yield of fresh sorghum can reach 7 t-8 t, which is about 2 t higher than that of the whole maize. From this point of view, sweet sorghum is used for silage production, which can effectively fill the sheep Industrial development on the demand for high quality forage material, while with the expansion of sweet sorghum planting area, can effectively reduce the cost of forage material, increase economic efficiency. Therefore, the sweet sorghum in Dingxi City aquaculture production is worth promoting the cultivation.
