What is the common feed for raising cattle in southern rural areas? There are four kinds of feed commonly used in beef cattle: plant feed, animal feed, mineral feed and special feed. Feed based on plant feed; Animal feed, mineral feed and special feed are all supplementary feeds for cattle. Therefore, it is necessary to build a good grassland and open up a source of plant feed for cattle. Plant feed is the most abundant and widely used feed. Feed for cattle includes green feed, coarse feed, juicy feed and concentrated feed. There are two ways for cattle to use green fodder: one is grazing: cattle can eat fresh green fodder on the pasture, except toxic plants, including all kinds of fresh weeds, cultivated grass and various branches and leaves. Second, the way of house feeding: use more mowing, hay and silage. The roughage used by cattle mainly includes various straw feeds. Such as wheat straw, rice straw, peanut vine and corn straw. This kind of feed has large volume, more crude fiber, less digestible nutrients and low nutritional value. Most of them are used as fillers in hay season after processing and adjustment. The juicy feed used by cattle mainly includes carrots, potatoes, melons and sweet potatoes. This feed is rich in water, less in fiber, good in palatability and high in digestibility, and can be regarded as high-moisture concentrate for cattle. The concentrate used by cattle is mainly mixture, including various seed feeds and various processing by-products, mainly corn, barley, wheat, bean cake, bran, rice bran, peanut bran and so on. Multi-diagonal additive can obviously promote the growth of dairy cows and beef cattle, and can improve the estrus pregnancy rate of dairy cows, the semen quality of breeding bulls and the milk yield of dairy cows. Its dosage is per ton batch 100g ~ 150g, or the body weight of each cow is 2mg ~ 6mg per kilogram per day. When adding, it should be mixed with concentrate, and then mixed and fed now. Acanthopanax senticosus mainly uses Acanthopanax senticosus extract, which is added to the drinking water of dairy cows at a dose of 0. 1 mg per kilogram of body weight. Sodium propionate is an energy additive suitable for young bulls.
