Xiangxiang winter tube pay attention to three points
On December 5th, when the reporter interviewed Bao Baoli senior livestock clerk in Shaanxi Baoji, he said that the Xiang pig was 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 the wall of a pig house is preferably one brick half or one billet, tight and without cracks. A stack of some fireweed around the wall book was used as the insulation layer. The pig house should be covered with plastic film, 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% for corn, 15% for soybean cake, 19.5% for wheat bran, 7% for various types of alfalfa, 1% for bone meal and fishmeal, and 0.5% for table 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. For example, rubbish is a good feed for pigs, which can greatly reduce 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, and the water should be heated when feeding. The feed should be regularly quantified. 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 to ensure that the pigs are not affected by the disease during the winter return.
