Bran is a by-product of wheat flour processing, and its nutritional composition varies with the variety, quality and flour yield of wheat. The higher the flour yield, the less embryo and endosperm components in bran, and the lower its nutritional value, energy value and digestibility. Wheat bran contains high crude protein and crude fiber, and its effective energy value is relatively low. It contains more B vitamins, such as vitamin B 1, vitamin B2, nicotinic acid and choline, and is rich in minerals. The proportion of calcium and phosphorus is not appropriate. Phosphorus is mostly phytate, accounting for about 75%, but it contains phytase, so its absorption rate is better than that of rice bran.

Wheat bran has high crude fiber content, loose texture and low specific gravity, and has the functions of laxative and laxative. It can also adjust the nutrient concentration of feed and improve the physical properties of feed. However, the following problems should be paid attention to during use:

First, the dosage should not be too large. Wheat bran is a feed with outstanding advantages and disadvantages, and the addition amount in meat rabbit feed should be appropriate. Generally controlled within 30%.

Second, pay attention to calcium supplementation. Although wheat bran is a good concentrate, its calcium is less and phosphorus is more, and the ratio is seriously unbalanced (1∶8). If you feed wheat bran in large quantities or only for a long time, it is easy to cause calcium deficiency diseases. Therefore, some calcium-rich feeds, such as eggshell powder, bone powder, stone powder and shell powder, should be added to the diet with wheat bran as the main concentrate.

Third, reasonable compatibility. The protein content of wheat bran is as high as14% ~17%, but its energy value is low, so wheat bran can't be used as the main energy feed, and it should be mixed with a certain feed with higher energy value, such as corn.

Fourth, pay attention to mildew and deterioration. Some flour processing plants often spray a certain amount of water on wheat when processing flour. If you spray too much water or don't dry it in time, there is a danger of mildew in hot season. In addition, continuous rain in the wheat harvest season makes wheat moldy to varying degrees, which affects the quality of wheat bran. Care should be taken when using it.
