During the growth and development of beef cattle, vitamin A deficiency is prone to occur. Especially in late autumn and winter, it is more likely to lack vitamin A. When the supply of vitamin A is insufficient, the intake of beef cattle decreases and the weight gain decreases. Therefore, from the autumn season (especially winter), we must pay attention to beef cattle supplement vitamin A.
The method is: For beef cattle that start fattening, take 100,000 g of vitamin A per head per day for 3 days, followed by another 3 days, followed by cyclical analogy. It can also be intramuscularly injected from 50 to 1 million μg, injected once every 10 days, followed by cycles and analogy. In this way, it is extremely beneficial to increase feed conversion efficiency and beef cattle growth and development.
