| 摘 要： | 通过对草地植物添加剂的最佳配方、最适量以及肉牛的最佳育肥方式对肉牛日增重、屠宰率、净肉率以及肉品质和风味的影响进行研究,旨在分析草地植物添加剂对肉牛生长性能的影响。结果表明,草地植物添加剂能促进肉牛的快速生长,提高肉牛的日增重,其中对于犊牛(C)、架子牛(S)和基础母牛(B)日增重效果最明显的分别是草地植物添加剂C3(44%松针+24%艾叶+12%黄芪+8%微量元素)(P0.01)、S3(48%松针+16%艾叶+8%大蒜+10%黄芪+18%微量元素)(P0.01)和B3(36%松针+14%艾叶+10%大蒜+12%黄芪+28%微量元素)(P0.01);草地植物添加剂的最适量的筛选试验表明,各年龄段的肉牛的草地植物添加剂的添加量占日粮的3.5%育肥效果最明显(P0.01);在北方冷季最佳的育肥方式为舍饲育肥。综上,在北方的寒冷季节养殖肉牛以占日粮3.5%的第3类(C3、S3、B3)草地植物添加剂配合舍饲增肥效果最明显。

| Abstract: | This experiment aims to study the effect of grassland plant additives on beef cattle growth performance,to determine the best additive formula and the most appropriate and best way of fattening beef cattle based on daily weight gain and slaughter rates,as well as net meat percentage,quality,and flavour using grass plants additives.The results show that grass plant additives promoted the rapid growth of beef cattle and improved their daily weight gain,and the most effective were the grass plant additives C3 (44％ pine needles+24％ Artemisia argyi+12％ garlic+12％ Astragalus+8％ microelement)(P＜0.01),S3(48％ pine needles+ 16％ Artemisia argyi+8％ garlic+10％ Astragalus+18％ microelement) (P＜0.01) and B3 (36％ pine needles+14％ Artemisia argyi+10％ garlic+12％ Astragalus+28％ microelement),store cattle (S) and based cows (B).Furthermore,the experiment on proper additive screening showed that the added amount of additives accounted for 3.5 ％ of the diet fattening effect,which was most obvious (P＜0.01) for all ages of beef cattle while the best fattening method was yard feeding in the north cold seasons.According the above results,the most obvious effect on fattening was observed with the grassland plant additive combined with yard feeding of beef cattle,and was the third class accounting for 3.5％ of the diet (C3,S3,and B3) in the north cold seasons. |
