Attention should be paid to the 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 play an important role in the development of animal husbandry. If used improperly, not only can not play the desired effect, but also lead to some diseases of livestock and poultry, and bring certain economic losses.

Wheat bran is a high-phosphorus and low-calcium diet with a phosphorus-to-calcium ratio of 4:1, which is contrary to the physiological ratio of calcium and phosphorus required by livestock and poultry. Excessive feeding of wheat bran can cause calcium deficiency in the proportion of calcium to phosphorus. Such as rickets of young animals, osteomalacia of adult animals, intestinal stones of equine animals, urolithiasis of male livestock and thin-shell eggs of poultry. The key measure for safe feeding of wheat bran is to master the reasonable dosage, which should generally be controlled below 20% of the formula feed. Specifically:

Eight weeks ago, chickens should account for 25%, 5%, 5%, 11%, 15%, 15%, 15%, 15%, 15% and 8%, respectively.

Pigs were not fed wheat bran before the age of 40 days, 12% kroner pigs under 55 kg, 55 kg ~ 90 kg fattening pigs accounted for 15%, breeding boars and pregnant sows accounted for 20%, and lactating sows accounted for 16%.

Wheat bran has sharp thorns, especially for machine threshing. When feeding, thorns can damage ulcers, eat grass slowly for a long time, chew not fine, fat feelings fall, physical decline. The key measure of reasonable feeding wheat bran is to go through harmless treatment first. There are two methods of treatment: one is rolling, a small amount of which can be rolled by stone mill, and the other is Alkalization, which consists of 3 kilograms of quicklime, 0.5 kilograms of salt and 150 kilograms of water, mixing and mixing, adding 100 kilograms of wheat bran and soaking for one day and night. Fish it into the basket, drain the liquid, and feed it. After alkalization of wheat bran, thorns soften, no wound cavity, and can supplement calcium.

Untreated wheat straw has high crude fiber content, low digestibility, poor palatability, livestock do not like to eat, and easy to cause knot to equine animals, which belongs to inferior feed. However, if given special treatment, the method is the same as wheat bran, all kinds of livestock can be fed. The second is ammoniation treatment, which can be treated with ammonia, ammonium bicarbonate and urea. Take urea treatment as an example: 10 kg urea is dissolved into 10% solution with 90 kg water, wheat straw is chopped, about 2 cm ~ 3 cm long, every 100 kg wheat straw is sprayed with 30 kg urea solution and sealed with plastic film. When the temperature is above 20 ℃, it can be taken after half a month, and it is better to feed cattle, sheep and other ruminants.
