Eight pigs in winter
In winter, the climate is cold. Farmers raise more pigs in open-circle, and they often raise for 6--7 months or more than 10 months before they can be slaughtered. According to the situation of swine breeding in Fanchang County, the author believes that the "eight-defense" live pigs can safely live through winter, grow fast, and have high profits. 1, wind and wind. The pig house in winter must block wind tunnels, hang straw curtains, and paste windows to prevent rat holes, cracks, gaps, and broken tops in the circle from being blown into "dragon style" and "thief style". The two winds blown into the pig house not only reduce the temperature, but also cause pig disease. The vent hole can stay at least one meter above the ground. 2, anti-humidity. Drying the pigsty is one of the main measures to ensure the health of pigs. Air is a kind of heat-conducting material, and the more humid it is, the stronger its thermal conductivity is. The faster the heat in the pigs in the circle is radiated. The pig's body is chilly, and it is necessary to get squashed. Crush injuries or even death occur. Epidemics are also prone to occur. Therefore, the circle must be a hardworking pad to ensure the dryness, and pay attention to the training of pigs to defecate urine, there is a dry place. 3, anti-low temperature. The optimum temperature for growing pigs is from 15 degrees Celsius to 25 degrees Celsius, and the normal growth temperature should also be above 8 degrees Celsius. In order to ensure the normal growth and development of pigs, the best way is to use warm sheds, that is, use thicker The plastic film shall cover all the tops of the circle, cover it with an inclined surface of about 30 degrees, which is convenient for daylighting, and if the circle temperature is too high in the noon, it shall be cleared after ventilation and snowing. 4, cold food. In winter, pigs eat nothing more than to protect themselves from the cold and increase their weight. Sows need to protect their normal growth and development of the fetus, so it is necessary to appropriately increase the energy feed during the seasoning to increase the cold. When feeding, it is best to mix and feed with raw food. If you need to block a small amount of water, the water temperature should be around 25 degrees Celsius. In case of thin-feeding, the feed should be warm, and less ground should be added to prevent cold and cold. 5, prevent chaos feeding. Feeding pigs should be stable in feeding quality and stable in feeding time. Ingredients should be based on different production performances and different growth stages. Do not abruptly change the quality. If you need to change feeds, increase the amount and change the feeding time should gradually change. 6, anti-cold drink. Pigs have a large demand for water, and the need for water is very important. When you lose 10% of your body's moisture, the pig will feel unwell and die. Therefore, it is necessary to replenish the pig's moisture from time to time. If there is no water in the circle, the pig will eat snow, eat ice, and drink urine. This will inevitably cause digestive diseases or other diseases. Therefore, we must constantly provide warm and clean drinking water, both to prevent patients and pigs need. 7, bite-proof frame. The normal growth of pigs, feeding must be comprehensive nutrition, lack of one or a few ingredients, not only slow growth, but also may bite frame "crashes", in particular, the lack of winter green feed, "evil" is more likely to appear Large, therefore, in the feed to supply a variety of vitamins, minerals and trace elements, and strong and weak groups, size, timely castration. 8, disease prevention. Low air temperature in winter, dry pig diseases, digestive tract diseases, respiratory diseases, infectious diseases, etc. are very easy to occur. To ensure the healthy development of pig production, it is necessary to keep the house clean, clean, and hygienic. Or spray disinfection, pigs should be vaccinated, and should be equipped with resident drugs, early isolation and early treatment of the disease.
