Beef cattle generally have a green feed requirement of 30-50 kg per head per day, and mixed cattle including young cattle and yaks require an average of 30 kg of green feed per head per day. To realize the uninterrupted supply of green fodder throughout the year, one-year-old pasture should be combined with perennial grasses, tropical grasses and temperate grasses, and single-species and interplanting should be used as unit areas.
The seasonal distribution method of pasture is: from March to June, temperate grasses are selected, such as perennial red clover, white clover, alfalfa, and annual ryegrass as main varieties; from June to October, tropical pastures are planted. Such as Sudan grass; from November to early March of the hay period, the main feed silage of juicy feed and a portion of hay. Crops suitable for silage include corn, sorghum, barley, and ryegrass. Legumes such as alfalfa, red clover and white clover are not suitable for silage alone.
A reasonable combination of pasture feeding can effectively reduce the incidence of diseases in the digestive system, and can also reduce the consumption of concentrate feed, and effectively maximize the benefits of fattening and rearing.
