Beef cattle autumn and winter more vitamin A
Beef cattle are prone to vitamin A deficiency during growth and development, especially in late autumn, and vitamin A deficiency is more likely to occur. Because the grass began to lignify in late autumn, crude fiber increased, and the content of carotene decreased greatly. The content of carotene in wheat straw, corn stalks and other feeds is even lower. In addition, beef cattle feed more concentrates, and concentrate carotene content is lower. Beef cattle require an increase in the amount of vitamin A during the stud fattening. When the supply of vitamin A is insufficient, the intake of beef cattle decreases and the weight gain slows down. Therefore, beef cattle should be supplemented with vitamin A from late autumn. The method: Start beef cattle fattening each day to take 100,000 international units of vitamin A, once every 3 days, interval 3 days, followed by cycling analogy.
