Effects of grassland plant additive on growth performance of beef cattle
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.
