Eight measures for raising pigs in midsummer
Pigs have thick subcutaneous fat, and it is difficult to dissipate heat. If the temperature is too high in summer, the appetite of the pig will be reduced, the weight gain will be slowed down or stagnated, and even the heat stroke may be dead. Usually, the suitable temperature for growing piglets is 20-30°C, the early period of fattening pigs requires 18-20°C, and the fattening pigs require 15-18°C. Therefore, in addition to newborn pigs, when the temperature reaches above 30 °C, comprehensive measures should be taken to reduce the temperature and prevent heatstroke, so as to avoid adverse effects on the normal growth of pigs. The following eight measures should be taken mainly. 1. Ventilation and ventilation: Ventilation is one of the important measures to remove heat from the pig house. In the summer season, the front and rear doors and windows of pig houses should be open to promote air circulation. In high-temperature and hot summer months, poorly ventilated intensive pig houses should be equipped with fans or fans to implement mechanical ventilation and eliminate house heat and air in order to prevent pigs from suffering heatstroke. 2. Cooling and cooling: Spray cold water on the floor, pig body, roof and playground of pig house, which is one of the effective measures for cooling and preventing heatstroke. 3, for enough drinking water: summer pigs need a large amount of water, to ensure that the pig's adequate clean drinking water is very important. The water requirement of pigs varies greatly depending on body weight, temperature, and feeding methods. In terms of body weight, pigs and pigs of more than 100 kilograms need more than 20 kilograms of water per head per day. In general, pigs drink about 2% of their body weight in summer. Drinking water should be fresh and clean. It is best to use an automatic drinker. 4. Greening and Shading: There should be planned afforestation around the pig house to create a cool environment with cool air temperature. Outside the house, take a arbor, plant some vines, and let them climb on top of the pig house to cool the shade and avoid direct sunlight on the pig house. 5, more feed green material: Summer is the rich season of juicy green feed, the weather is hot, poor appetite pigs, should be fed more green and juicy feed, such as fresh clams, sweet potato clams, pumpkin, watermelon rind, beet leaves, etc. Not only has the anti-hot summer refreshing effect, but also easy to digest, good nutrition. The green material can be chopped and fed, and can also be fed together with the compound material. 6, increase nutrition: summer due to high temperatures, pig feed intake decreased, in order to ensure the normal growth and development of pigs in the feed should be properly increased protein nutrition, such as high quality bean cake, legume grass powder, fish meal, etc., usually pig In the diet, the protein content should account for 16% to 18%, and the finishing pigs should reach 15% in the early stage and 12% in the later stage. At the same time, it should be fed as early as possible and cool at night. It is best to feed it once at night. 7. Construction of baths: In conditional pig farms, summer baths should be added to the swine's sports ground for bathing of pigs to facilitate heat gain. The bath can be made of masonry and cement, generally 0.5 meters deep, on one side within 30 slopes, built into small steps to prevent the pigs from slipping. 8. Do a good job of preventing epidemic: In summer, the temperature is high and the germs multiply quickly. For this reason, the pens should be cleaned daily, and the excrement should be transported in a timely manner and fermented. The inside and outside of the pig house should be regularly sterilized. Four walls should be sterilized with 20% lime milk. The ground should be sterilized with 1%-2% fire alkali solution. The drinking utensils shall be disinfected with alkaline water or 0.1% benzalkonium bromide solution and rinsed with boiling water. For the newly transferred pigs to be fattened, they must be dewormed once and take care of the diseases such as diarrhea, warts, and eczema.
