In areas where roughage resources are scarce, how to control the concentrate and coarseness of cows when they are housed in cows
The proportion of materials (Wansheng, Jiangxi Minxing Enterprise Group Special Feed Factory)?
A: About 50% of the crude protein and milk production required for high-yielding dairy cows (more than 9 000 kg of milk per year) should come.
For forage, about 80% of the fiber required (NDF) should come from forage. Only high quality forage can satisfy this
Claim. In the case of using inferior forage grass, increasing the proportion of concentrate can achieve a certain level of milk production, but
It is still not comparable to the level of milk that can be achieved with high-quality forage and moderate amounts of concentrate. Concentrate in the diet
The ratio should not exceed 60%, and the daily feeding amount should not exceed 15kg, otherwise it will affect the rumen function.
It has a decrease in milk fat percentage and milk production and a metabolic disorder caused by acidosis. When the concentrate is fed a large amount, it can be taken
The following measures: 1 feeding of concentrate feed, no more than 3kg each time; 2 adding high fiber, high energy in the concentrate
By-products, such as whole-ear corn, corn gluten scraps, corn bran, soybean hulls, etc.;
Such as whole oil seed (soy, cottonseed and sunflower seeds) and rumen do not degrade fat, but the total fat of the diet
The amount is not more than 7%; 4 high-fiber such as soybean hull, oat processing waste, cottonseed hull, corn cob and beet pulp
Dimensional by-products to dilute a small amount of high-quality forage; 5 to feed more silage corn; 6 to use full-mix diet
Feeding method.
