In order to investigate the effects of grape pomace on production performance and meat quality of beef cattle, the whole corn silage was replaced by grape pomace silage, and to anal‐ yse the changes of growth and development, slaughter performance and meat quality of beef cattle. The main beef cattle breeds Angus and Simmental cattle with 30 heads each were se‐lected and divided into test group A, group B and control group, the average body weight is (283.00± 2.47) kg, and the test group is fed grape pomace silage diet and control is fed whole plant corn silage diet. The result showed that compared with the control group, test groups of the weight gain over the trial period were higher than control group 16-36 kg, and average daily gain were higher 40-150 g; slaughter at the age of 20-month-old, the carcass weight of test group A and B were higher than control group 67 kg (P< 0.01), 38 kg (P<0.05), respectively; the dressing percentage and net meat percentage were seven percent‐ age points and six percentage points higher than the control group, respectively (P<0.05), the highest slaughter percentage and net meat percentage were about 65% and 58%, respectively; the fat and protein contents of beef in test groups were higher than those in control group, and the shear force was lower than that in control group (P<0.05); the polyunsaturated fatty acid (PUFA) was mainly composed of lin‐ oleic acid, α-linolenic acid and arachidonic acid. The contents of linoleic acid and α-linolenic acid in experimental groups were significantly higher than those in control group (P<0.05), and the ratio of n-6/ n-3 PUFA in beef was about 10∶1, which was lower than that in control group. In summary when grape residue silage was used as the main roughage source, it could improve the growth performance, carcass weight, slaughter percentage and net meat percentage of beef cattle after slaughter, increase the types of fatty acids and the content of main fatty acids, improve the ratio of n-6/n-3 PUFA, and improve the beef quality to a certain extent.
