Wheat bran is rich in vitamins such as vitamin B and high in phosphorus. Adding some wheat bran to the concentrated solution will make the nutrition more comprehensive and balanced. Wheat bran is rich in crude fiber, which has a certain laxative effect and is helpful to improve the digestive function of dairy cows. Feeding cows after delivery can accelerate the recovery of digestive function and appetite. The crude fiber in wheat bran can inhibit the proliferation of intestinal bacteria and play a certain role in preventing bacillary dysentery.

First, the efficacy and role of wheat bran in raising cattle

1. What is the effect and function of feeding cattle with wheat bran?

(1) Balanced nutrition

The nutritional value of wheat bran is lower than that of corn and soybean meal, and it contains more crude fiber and is not easy to digest, so it is not the most ideal concentrated feed resource. However, wheat bran is rich in vitamins such as vitamin B and high in phosphorus. Adding some wheat bran to the concentrated solution will make the nutrition more comprehensive and balanced.

(2) promoting digestion

Because wheat bran is rich in crude fiber, it has a certain laxative effect and helps to improve the digestive function of cattle. Feeding some wheat bran to postpartum cows can speed up the recovery of digestive function and appetite. The crude fiber in wheat bran can also inhibit the proliferation of intestinal bacteria and play a certain role in preventing bacillary dysentery.

2. The harm caused by overfeeding wheat bran.

(1) Dry food won't last long.

Because of the high content of crude fiber in wheat bran, it has a certain laxative effect. When the feeding amount is large, it will affect the normal digestion and absorption of cattle, and the feces will become thinner and softer, so undigested feed can be seen. In the long run, cows will eat dry for a long time.

(2) Calcium deficiency

Because of the high phosphorus content in wheat bran, it is bound to cause the imbalance of calcium and phosphorus ratio in cattle when feeding wheat bran in large quantities, which will lead to calcium deficiency in cattle.

(3) Stone

Feeding a lot of wheat bran when fattening cattle can easily lead to lithiasis, and even lead to the death of cattle in severe cases.

Second, what is wheat bran?

1, what is wheat bran?

Wheat bran is not only the outer skin of wheat, but also the seed coat screened by grinding wheat flour. It is wheat yellow, flaky or powdery, and its main components are fiber, aleurone, and some minerals and vitamins.

2. The method of feeding cattle with wheat bran

(1) calfskin

When Niu Gang of Niugang calf started feeding, its digestive function was still weak, so it was impossible to feed too much wheat bran, which accounted for about 65,438+00% of concentrate. With the growth of calves, the digestive ability is further strengthened. In order to prevent calf constipation, the proportion of wheat bran in concentrate can be increased to 65,438+03%-65,438+04%.

(2) Breeding cattle

In the early growth stage, that is, from weaning to bone growth stage, because the rapid growth of bones requires a lot of calcium and phosphorus, the proportion of wheat bran in concentrated feed can be kept at 65,438+03%-65,438+04%, but at the same time, attention should be paid to calcium supplementation to avoid the imbalance of calcium and phosphorus metabolism.

(3) Breeding cattle

Cattle are prone to constipation, so it is advisable to feed more wheat bran to promote digestion and relieve diarrhea. The proportion of wheat bran in the concentrate of empty pregnancy and early pregnancy is about 15%.

② With the growth and oppression of the fetus in the second and third trimester of pregnancy, dairy cows are more prone to constipation, and the proportion of wheat bran in concentrate can be gradually increased to 18%-20%.

③ With the increase of postpartum milk production, although the demand for calcium and phosphorus increased, the feeding amount of concentrate also increased, so the proportion of wheat bran in concentrate could be reduced to 14%- 15%.
