| 摘 要： | 选用６０头盘江黄盘江牛，随机分为４个组，其中３个试验组、１个对照组，进行不同补饲水平的育肥试验。在补饲精料每千克含ＤＭ０．８８４ｋｇ，ＣＰ０．１４３ｋｇ，ＮＥｍｆ７．０３ＭＪ的饲料情况下，补饲组的增重水平和育肥效益，明显优于不补饲组。其中以补锔．５ｋｇ组的效果最好，其日增重达到０．７８３ｋｇ比对照组０．２３１ｋｇ提高２３９％，育肥收入和日均收入分别为２１８．７９元和２．４３元，比对照组的１４５．５

| Abstract: | The
finishing trial with 60 Panjiang cattle divided randomly into 3 treatments and 1 check was
carried out.With the complemental grain-feeding of DM0.88kg, CP0.143kg, NEmf7.03MJ per
kilogram, both gaining weight and benefit of finishing for treatments are obviously better
than CK, of which the grain-feeding group of 2.5kg is the best with daily gain of 0.783kg
and 239% higher than CK (0.231kg), and total daily income reach 218.79 and 2.43 yuan and
33.6% higher than CK (145.53, 1.62yuan). The result indicated that grass finishing could
improve the daily gain,shorten feeding period, and increase income of feeding cattle. |
