Use of guanidineacetic acid in improving production performance, slaughter performance, and meat quality of beef cattle

The present disclosure relates to the field of feed additives, and in particular to use of guanidineacetic acid in improving production performance, slaughter performance, and meat quality of beef cattle. The present disclosure provides the use of guanidineacetic acid in improving production performance, slaughter performance, and meat quality of beef cattle. The guanidineacetic acid is administered at a daily dose of 5-40 g/cattle. The guanidineacetic acid of the present disclosure can ameliorate rumen fermentation, raise the average daily gain of the beef cattle, reduce feed-gain ratio, increase body antioxidant capacity, carcass weight, and loin eye area, lower drip loss of beef, and effectively improve the production performance, slaughter performance, and meat quality of the beef cattle.
