| 摘 要： | 目的]探索放牧绵羊微量元素舔砖的制作工艺及饲用效果。方法]以石粉、食盐、饲料级微量元素、膨润土和糖蜜等为原料研制放牧绵羊微量元素饲用舔砖，并研究所制舔砖对新疆细毛羊生产母羊和育成羊的饲用效果。结果]添砖的最佳制作工艺为：微量元素预混料8％，石粉5％，食盐66％，膨润土9％，糖蜜12％，冲击压力50t，阴干时间9d；试验组育成羊体重、毛长、体高、体长分别增加6．12kg、0．96、4．90、6．99cm，而对照组（自由舔食食盐）分别增加1．60kg、0．36、3．73、5．46em；试验组生产母羊的羔羊初生体重、断奶育成羔羊数、羔羊成活率和母羊繁殖率分别为4．02±0．91k/只、64只、94．1％、128％，而对照组分别为3．81±0．86kg／只、54只、81．8％和108％。结论]所研制舔砖对绵羊的饲用效果较理想。 |

| Abstract: | Objective] The study was to explore the making technology and feeding effect of trace element lick block for grazing sheep.Method] With stone powder,salt,feed-grade trace elements,bentonite and molasses etc as the materials,the trace element lick blocks for grazing sheep were prepared,and the feeding effect of trace element lick block on ewes and lamb hogs of Xinjiang fine wool sheep were studied.Result] The optimum making technology of trace element lick blocks for grazing sheep was that premix feed of 8%,stone powder of 5%,salt of 66%,bentonite of 9%,molasses of 12%,impact pressure of 50 t and shady exposing time of 9 d.The body weight,wool length,withers height,body length of lamb hogs in tested group were increased by 6.12 kg,0.96,4.90,6.99 cm resp.and those of CK group(free licking salt) were increased by 1.60 kg,0.36,3.73,5.46 cm.The birth weight of lamb,number of weaned growing lamb,survival rate of lamb and reproductive rate of ewes in tested group were 4.02±0.91 kg/ sheep,64,94.1%,128% resp nd those of CK group were 3.81±0.86 kg/sheep,54,81.8% and 108% resp.Conclusion] The feeding effect of the prepared trace element lick blocks on grazing sheep was more ideal. |
