The Xiang pig is favored by consumers because of its tender taste. The following questions should be paid attention to in winter feeding.
Insulation. The cold resistance of the pig is lower than that of the local pig, and the insulation is not good, which not only affects the normal growth but also causes losses. The thickness of a wall of a brick or half of a pig house is appropriate, and it is tight and crack-free. A stack of fireweed was added around the wall book as insulation. 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. Ventilate once or twice a day before and after noon every half hour. The excrement should be promptly cleaned up, and the place to sleep should be changed frequently for hay, dry leaves, and dry sawdust. If the urine nest pigs must be tuned.
The feed must be full price. Feed full price means that the feed to the pig contains the various nutrients required by 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 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 the different growth stages of pigs, the proportion of feed should be changed. The principle is that there should be more concentrate in the early stage and less concentrate in the later stage. When selecting feed, it is necessary to adapt to local conditions and try to use nutrient-rich, low-cost feeds. For example, rubbish residue is a very good feed for pigs, which can greatly reduce the input of fine material, but the rubbish residue cannot exceed 1/3 of the total input.
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, rotten vegetables do not feed.
To feed cooked food, hot food. The origin of pig feed is mainly cooked food. 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. Feed should be soaked in water in advance, hot water when feeding, regular feeding, 3 times for big pigs and 4 times for piglets.
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.
