Wheat bran has a large volume, high fiber content, good palatability, and is an excellent feed ingredient for dairy cows, beef cattle feed and sheep feed. But the use of bran also has some need to pay attention to, improper use will also cause unnecessary trouble.
One, the advantages of wheat bran
1, high crude fiber content. Due to the high content of crude fiber in wheat hulls, so that the content of crude fiber in the bran is also high (8.5% to 12%), which has a slight impact on the energy value of wheat bran. Effective energy value is low, can be used to regulate the concentration of nutrients in the feed;
2, unsaturated fatty acids: fat content of about 4%, which is high in unsaturated fatty acids, easy to oxidize and rancidity;
3, high vitamin content: vitamin B and VE content is high, the content of B1 is up to 8.9mg/kg, B2 is up to 3.5 mg/kg, which is sufficient to meet the needs of the growing and fattening sheep. This is enough to meet the needs of growing and fattening sheep. But VA, VD content is less. Mineral content is also relatively rich;
4, anti-constipation: wheat bran is loose in texture, contains a moderate amount of sulfates, light diarrhea, can prevent constipation;
5, increase lactation: 10% to 15% of the use of dairy cattle concentrate, can increase lactation, but the amount is too high, but the effect is lost. Do not add more than 30% in the concentrate supplement;
6, price: wheat bran is cheap, nutritious and cost-effective.
Second, the shortcomings of wheat bran
1, the amount of easy to lead to diarrhea: because of the high content of crude fiber, difficult to digest, feed more easily lead to diarrhea;
2, calcium and phosphorus is extremely unbalanced: calcium (Ca0.13%) phosphorus (P1.18%) ratio is extremely unbalanced, calcium: phosphorus ratio of 1:8 or more, it is very easy to lead to urinary calculi. And phosphorus is mostly phytate phosphorus, about 75%, but contains phytase, so with these feeds should pay attention to calcium;
3, many areas can not buy:
Wheat gluten is mainly concentrated in the production of wheat, such as North China, especially in Shandong, Henan, Hebei, Anhui, Jiangsu region also produces wheat gluten. But other areas of wheat bran is not so easy to buy (or the road is farther, the purchase cost is higher), this time can only use other alternatives, commonly used alternatives include rice husk powder, rice bran, rice bran and so on.
For the record, due to the low nutrient content of these raw materials, and crude fiber content is higher, more indigestible, so these can be partially replaced by gluten, and is not recommended for long-term use.
Lastly, I need to say that many regions say that wheat bran is cool, in the winter said that adding wheat bran is not good, here to dispel rumors, there is no evidence, data, experiments that wheat bran is cool, as long as not a large number of additions (generally in 10% or so are not a problem) are not a problem, but also in the winter to reduce the amount can be appropriate.
Again, bran is generally about 10% of the concentrate supplement, which doesn't have a big impact on the whole concentrate supplement.
The 3 great uses of wheat bran
Particularly in the production of ewes, wheat bran can show its charm. Mainly in the following three aspects:
1, ewes lambing after not recognizing the lamb, do not lick the wool to the lamb how to do?
We can try to use wheat bran to dry the lamb package next time we encounter this situation, after which the ewes will really be more willing to approach the "baby sheep" it;
2, careful, patient farmers can be in the ewes after the birth of brown sugar and wheat bran according to the ratio of 1:2.5, add boiling water 2~2.5 mL of boiling water to brew letting the ewes to be more careful and patient farmers. mL of boiling water to let it drink, can better care of the ewe's intestinal tract, but also help the recovery of physical strength.
Of course, if the general production goes well, most people may not be so attentive, but if we all take good care of all aspects, then our sheep will surely be a lot of smooth;
3, the ewe is not easy to get under the fetal coat after delivery, with bran can also be improved, in addition, there is also a certain promotion of ewes in time for the role of estrus.
