| 摘 要： | 对冷季放牧绵羊补饲尿素-糖蜜营养舔砖效果进行了分析。选用蒙古系绵羊后备母羊60只，随机分为3 组，在全放牧条件下，试验1 组每天只均补饲整粒玉米Zea mays 100 g和尿素-糖蜜营养舔砖200 g，试验2组每天只均补饲整粒玉米300 g，3组（纯放牧组）不补饲。结果表明，试验1组比纯放牧组和试验2组日增体质量分别提高205.65 g(P <0.01)和58.87 g(P<0.01)，头均收入分别比纯放牧组和试验2组增加41.99元和21.14元。

| Abstract: | Totally 60 Mongolian sheep were selected and randomly divided into 3 groups to study the effect of urea-molasses nutrient block(UMNB) in cold season(Group 1: 100 g of corn and 200 g of UMNB per day;Group 2: supplied with by 300 g of corn per day;Group 3: control,full grazing on pasture without supplement).The results indicate that daily weight gain of Group 1 was 205.65 g higher than that in Group 3(P < 0.01) and 58.87 g higher than that in Group 2(P < 0.01);the average benefit per head in Group 1 was 41.99... |
