Abstract In order to confirm the effect on the quality in a good stall period adding plant oil to daily grain .Chooses 16 YanBian ox that have health bodies,and divide into 4 groups stochastically,4 heads as a group,the comparison group feeds the basic daily grain,the experiment group separately in-creases 4%,5%,6%(on the base of concen-trated feed)of plant oil,raise 88d. After butcher,choose the back to be longest muscle to freeze for 3 months under -20℃,start to analysis the quality of beef in 0,2,4,6 dafter defrosts for 24h under 4℃.The result indicates that:meat luster of experiment group is better than all good comparison groups.As the level of plant oil in daily grain increase,the saturated fatty acid takes on the descending tendency,having signed divergence compared with the comparison group (P<0.05),but the experiment groups are not signal(P>0.05); The unsaturated fatty acid takes on the trend of escalation,the divergence between 5% 6% plant oil group and the comparison group difference is remarkable (P<0.05).The test result indicated that:adding 5% of plant oil is the best in improving the quality of beef and extending the time of stall.
