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 mays100 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。
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 RMB Yuan higher than that in Group 3 and 21.14 RMB Yuan higher than that in Group 2.
