After the beginning of autumn, the weather turned cold. At this time, the management of beef cattle also differs from summer, and it is necessary to supplement and store all kinds of fresh grass feed in time to prepare for overwintering. Recently, the reporter interviewed a member of the Expert Advisory Group of the newspaper and Professor Lin Qing of the Animal Science and Technology College of Northwest Agriculture and Forestry University. He asked the farmers to talk about how to manage the beef cattle autumn.
Adhering to grazing Lin Ching said that farmers should use the time that autumn forages have not yet dried up to grazing beef cattle and collect some grasses, leaves, and crop straws and vines to store them as a forage during the winter of beef cattle. In addition, beef cattle may be supplemented with some concentrate feed supplements. With enough feed to enter the fall, beef cattle are gradually converted from grazing to feeding. At this point, feed reserves need to be made. Lin Qing suggested that the use of pasture, corn, straw and silage, silage, storage, ammoniation and other technologies combined production of roughage. The choice of concentrate feed includes energy feed and protein feed. The energy feed is dominated by corn, protein feed can be rapeseed cake and cotton aphid instead of soybean meal. In addition, some feed additives have to be stocked to supplement the nutrient content of the feed.
Doing a good job of ventilating forest clear told reporters that beef cattle in the temperature of 0 °C ~ 4 °C does not affect the growth and development speed, but many cattle farms now pay too much attention to the insulation of the cowshed, so that the barn high humidity. When the barn's humidity exceeds 70%, the growth rate of the cattle will decrease. Therefore, ventilation facilities need to be taken into consideration when building the barn. In addition, to ensure that cattle have sufficient light, cattle can be pulled out of the house on sunny days for natural light; in autumn and winter, cattle are house-fed, the herd density increases, the risk of disease transmission increases, and ventilation can be to a certain extent. Lower the incidence of cattle.
