1. Fattening method of Distiller's grains
Red distiller's grains have a lot of fibers, so they are not suitable for feeding pigs with low digestibility. For the cattle company, It is the quickest way to fatten cattle that good fattening foods and more economical.
The fattening period of distiller's grains for adult cattle fattening in 90 days and that of young cattle is 120 days. In the beginning, a large amount of hay and roughage was fed, and only a small amount of distiller's grains was given to train their feeding ability and promote the increase of gastrointestinal volume and rich the beef nutrition. After 15～20 days, the distiller's grains were gradually increased and the amount of hay was reduced.
By the middle stage of fattening, the feeding amount of distiller's grains can be greatly increased. Cattle weighing 350～400 kg can be fed 50～60 kg of liquor willow per day, and cattle aged 1.5～3.0 can be fed 40～50 kg of distiller's grains per day. Fattening cattle with wine shoots can save concentrate and reduce cattle feed prices. During the whole fattening period, cattle only uses 50～150 kg of concentrate, gaining 1000～1200 g per day, and 600～700 g per day without concentrate supplementation.
2. Fattening method of silage
Using silage to fatten beef cattle is a fattening method advocated and promoted actively. Especially where there are few by-products in the food industry, it is more important. To meet the needs of fattening beef cattle, cattle farmers should develop silage bases in a planned way and produce large quantities of high-quality silage. Corn silage is the best grain to fatten cattle for fattening calves or adult cattle with high yield and quality. It has a good effect and should be actively promoted.
The length of the fattening period and feeding principle are similar to those of distiller's grains. The maximum amount of silage is 25～30 kg for adult cattle beefmaster and 15～20 kg for young cattle. Salt can be slightly higher. Adult cattle are given 80～100 grams a day and young cattle 60～80 grams a day. If silage quality is good, the concentrate can be fed less. However, the supply of high-quality hay should be satisfied as far as possible.
3. Fattening method of beet pulp
It is also economical to fatten beef polled cattle with large amounts of beet pulp near sugar refinery. Use fresh or dry beet pulp. At the beginning of fattening, 40～50 kg per head per day can be fed, and then gradually increased. During the middle period of fattening, about 70～80 kg of beet pulp was fed daily, and 50～55 kg of beet pulp was fed at the end. If feeding cattle with dry beet pulp, they should be soaked in water for 6～10 hours before feeding. Beef cattle fattened with beet pulp can gain 1000 grams of weight per day.
4. Fattening method of feeding concentrate properly mainly by mowing the grass
This method adopts all barn feeding or fencing fattening method. Artificially planted forage, mowed or mixed hay was used for feeding, and some mixed concentrates were used for fattening. It is convenient to manage and beneficial to mechanized and factory cattle raising.
Whatever method is used to fatten beef cattle, an environment conducive to cattle weight gain should be created. Cattle barn should be able to prevent cold in winter and prevent heat in summer, and the barn temperature should be at 8～10 ℃. The barn should be dry, with fresh air and plenty of light. Keep cattle clean and hygienic regularly, dramatically wipe twice a day, and exercise properly to increase appetite. Feed three times a day and drink water two to three times a day. Feed more roughage at the beginning of fattening, then gradually reduce the roughage and increase the concentrate, and the cattle rancher should pay attention to the reasonable proportion of the concentrate to the roughage.
