Wheat bran is wheat bran, which is usually used to raise pigs. It is beneficial to the peristalsis of the pig's stomach and can make the digestive tract healthy and energetic. Because of its low density, it is a good feed containing protein.

It belongs to medium energy feed and is an indispensable part of energy centralized regulation.

Wheat bran crude protein is as high as 12- 17%, crude fiber is 8.5- 12%, phosphorus content is also very high, about 1.09%, lysine, methionine, VB, manganese and zinc are also rich, calcium content is low, and iron content fluctuates greatly. The energy absorbed per kilogram of coarse wheat bran is between 6.28-7. 1 1mj, while that of fine wheat is 7.95 MJ. Their crude protein content is different, ranging from 12% to 18%.

Wheat bran has high crude protein content, but low quality, and amino acids can not fully meet the needs of pigs, so it needs to be mixed with high-quality protein.

Wheat bran does not contain B 12, but it contains more phosphorus and less calcium, so it is difficult for pigs and chickens to absorb phosphorus.

Bran has loose texture and good fusion. Animals such as cattle and horses can be fed in large quantities to promote digestion.

Feeding some wheat bran during the fast birth and lactation of livestock plays a health care role. bran

Wheat bran is a very good feed for breeders and laying hens, especially for high-density cage chickens, which can account for 30% of food consumption. The proportion of wheat bran in the diet of fat pigs shall not exceed 20%. Weaned piglets should not exceed 10%, and should be mixed with corn sorghum.

Wheat bran accounts for 65,438+02%-65,438+05% of livestock diet, 5% of piglets, 3% of chickens, 65,438+00% of adult chickens, 5%-65,438+05% of laying hens and 20% of postpartum females. Calcium should be supplemented when feeding bran, such as broken eggshells and broken bones. Bran has the function of mild diarrhea, which can relieve sow constipation. Therefore, sows should be supplemented before and after delivery. Bran goes bad easily, so keep it well.

But is bran the most economical feed and can replace other feeds? No, eating the same volume of feed will reduce the energy protein absorbed by chickens and can't lay eggs to the maximum extent.

Only about 3% to 5% bran can be added to chicken feed during the growing period, otherwise, chickens will not gain meat.

In a word, bran is rich in nutrition, but its usage and function are different for different livestock. It is necessary for large livestock, and less for small livestock. We should treat this matter dialectically and avoid unnecessary losses.
