What is the nutritional value of wheat bran? How to use it? Wheat bran, commonly known as bran, is one of the by-products of flour processing with wheat seeds as raw materials, accounting for more than 10% of wheat seeds. Due to the different purposes of wheat milling and the degree of milling, the proportion of wheat bran is also quite different, and the nutritional content is also different. The natural moisture content of wheat bran is 10.o%, the highest is 12.8%, and the lowest is 6.3%. Wheat bran contains 9.5% crude fiber; the higher the flour extraction rate of wheat, the higher the crude fiber content of wheat bran, the less nitrogen-free extract, the more flour existing in wheat bran, and the higher the digestibility. The metabolizable energy of coarse wheat bran is 7.11-6.28 MJ per kilogram, and the metabolizable energy of fine wheat bran can reach 7.95 MJ per kilogram. Due to the different flour extraction rates, the crude protein content is also different, generally 14.4-15.0%, more than 18%, and less than 12%; although wheat bran contains high crude protein, its quality is poor , its amino acid content can not meet the nutritional needs of pigs, chickens. Therefore, when using wheat bran as the raw material of compound feed, the balance adjustment should be considered with high-quality protein feed. Wheat bran is rich in manganese, zinc, selenium and vitamin B, but not vitamin B12; it contains more phosphorus and less calcium, and phytate phosphorus accounts for 2/3 of phosphorus, which cannot be absorbed and utilized by pigs and chickens.
In addition, wheat bran is characterized by loose texture, large volume, good palatability, and is a good feed for all livestock. For dairy cows and equine animals, it can be fed in large quantities, which can help gastrointestinal motility and maintain the health of the digestive tract. For breeding livestock, especially feeding before labor and lactation, it has more health care effects. Wheat bran is not suitable for feeding finishing pigs and broilers. Wheat bran is a good feed for breeding pigs. Wheat bran is also a good feed for laying hens, which can adjust the excessive concentration of the diet and is beneficial to normal digestion, especially for high-density cage chickens. For growing chickens with restricted feeding periods, wheat bran, which accounts for 30% of the diet, is also effective. Wheat bran can be called health care feed. Wheat bran is easily spoiled and moldy, so attention must be paid to dry and ventilated storage. Dosage of wheat bran: 12-15% for pigs, 5% for piglets, 3-4% for chicks, 10-15% for chickens, 5-10% for laying hens, 20-25% for postpartum females , General mule concentrate feed can account for 30 to 40%. In addition, it is appropriate to feed more in summer and less in winter.
