The Xiang pig is favored by consumers because of its tender taste. In recent years, due to the popular international market, the Ministry of Agriculture has listed it as a "key protection and development project." Farmers should pay attention to the following issues in raising. (1) The cold resistance of the insulated pig is lower than that of local pigs, and the insulation is not good, which not only affects normal growth but also causes losses. The thickness of a brick or half of the wall of a pig house is appropriate, tight, and free of cracks. A stack of some fireweed around the wall book was used as the insulation layer. Pighouses should be plastic plastic film sheds, preferably two plastic films. The shed was covered with straw curtains at night. The shed must have ventilation holes, and it should be passed 1-2 times before and after noon every day. Every half hour can be. The excrement should be promptly cleaned up, and the place to sleep should be changed frequently for hay, dry leaves, and dry sawdust. If there is a pig in the urine, it must be taught. (2) Feed Full price feed Full price refers to the various nutrients needed to feed the pig to contain the pig's body. Due to the high energy consumption of pigs in winter, it is necessary to ensure that the amount of food is sufficient and the feed ratio is reasonable. The type of feed should be as diverse as possible, so that the various feeds of the rations to be added can complement each Other nutritionally. The palatability of the quality of the feed used is better. The proportion of commonly used feed is 56% corn, 15% soybean cake, 19.5% wheat bran, 7% of various mealworms, 1% of bone meal and fish meal, and 0.5% salt. During different growth stages of pigs, the proportion of feed should be appropriately changed. The principle is that there are more concentrates in the early stage and less refined materials in the later period. When selecting feed, it is necessary to adapt to local conditions and try to use nutrient-rich, low-cost feeds. If rubbish is a good feed for pigs, it can greatly increase the input of concentrates. However, the amount of bean curd refuse should not exceed one-third of the total feed. Conditional farmers can also incorporate a small amount of fermented chicken manure in the pig's feed. Because of the habit of eating green feed, the pig is a problem that cannot be ignored in keeping. Winter can use cabbage, radish, carrots, potatoes (maize cooked well) instead of green feed. Don't feed rotten vegetables. (3) To feed cooked foods and hot foods. Cooked feed can increase feed utilization. In the cold winter, feeding cooked food can enhance the pig's ability to keep out the cold and speed up the growth. If you feed the cooked food unconditionally, you should feed it at least. The feed should be soaked in water in advance. When fed, it should be regularly quantified for hot water and feeding. The big pigs should be fed three times and the pigs should be fed four times. Although the incidence of livestock in winter is low, health and epidemic prevention cannot be ignored. The piggery should be sterilized on schedule and the vaccine should be started at the end of the first month. It will ensure that the pigs will not be affected by rickets when winter returns to spring. China Agricultural Network Editor
