Rational use of three-wheat feed
Wheat bran, wheat bran and wheat straw are called three-wheat feed, which is an important feed in the main wheat producing areas. Rational use of three-wheat feed can promote the development of animal husbandry. If used improperly, not only can not play the desired effect, but also lead to livestock and poultry infected with some diseases, resulting in economic losses. Wheat bran is a kind of feed with high phosphorus and low calcium, and the ratio of phosphorus to calcium is 4 ∶ 1, which is contrary to the physiological ratio of calcium and phosphorus required by livestock and poultry from 1.5 ∶ 1 to 2 ∶ 1. Excessive feeding of wheat bran can cause calcium deficiency in the proportion of calcium to phosphorus. Such as rickets of young animals and rickets of adult animals.
