Summer pig three attention

In summer, the temperature is high, but under the pig's skin is thick, and the ability to regulate body temperature is poor. This can easily lead to a decrease in feed intake and a decrease in resistance of the pig. Especially for pregnant sows, if not properly managed, it is likely to cause abnormal growth and even miscarriage of piglets. At present, the market price of live pigs soars and remains high. Under such circumstances, pigs are dead or lost. Therefore, how to effectively raise and manage pigs in order to enhance disease resistance and increase production capacity has become the key for farmers to obtain high profits this summer. Yang Heping, an animal husbandry expert at the Yangling Vocational and Technical College, pointed out that pig raising in the summer needs special attention to the following three points.
Temperature control In order to ensure the normal production of the summer farms, effective control measures must be taken according to the temperature requirements of various types of herds. The pig houses should be well ventilated to remove heat from the pig houses and reduce the temperature in the houses. “You can set a suitable inlet and outlet in the pig house. If the area of ​​the pig house is large, it is better to install a fan for ventilation and cooling,” said Yang Heping. In recent years, domestic and foreign research and development of a variety of cooling facilities suitable for different pigs have been widely used in the production of large-scale pigs. There are many applications in addition to the fan there are sprinklers, wet curtains and so on. For unqualified farms, Yang Heping suggested that a shallow pond can be built in the pigpen or directly on the ground to let the pigs lie in the water to cool down, or a sprayer can be used to spray the water mist on the pigs and evaporate through the water vapor. When absorbing the heat from the pig, the purpose of cooling is achieved. “Some farmers worry that the pigs will suffer from heat stroke. They will pour cold water on the pigs and want to cool them down. They do not know that doing so is harmful and unhelpful. From a lighter point of view, the pigs may have a high fever and inflammation of the lungs. The weight of the pigs may directly lead to the death of the pigs. "The average pig house temperature should be controlled at about 25°C, and it is better not to exceed 30°C. Most of the rural areas are open-type pig houses. Yang Heping emphasized that before the high temperature comes, we should shade the arbor to avoid heat exposure caused by the direct exposure of the pigs to the sun. We can also plant a certain amount of trees around the pig house, in addition to purifying the air. Can also play a role in shading.
Healthy environment Summer is the season when germs are very active. High temperature and high humidity can easily cause various diseases in pigs. In order to prevent the occurrence of porcine infectious diseases, pig farms must pay attention to the cleanliness and disinfection work of pig houses. "We must regularly clean sinks and troughs, remove excrement in time, and disinfect pig houses and surrounding sites irregularly." Yang Heping said that there are also many mosquitoes in the summer. If the pigs suffer long-term mosquito bites, it will not only affect production, but also cause diseases easily. So we must exterminate insects in time. Trichlorfon can be sprayed with the appropriate amount of water, but the concentration should not be too high, otherwise it will affect the pig. In addition, pigs must be given regular immunizations to prevent epidemics.
Nutrient conditions Some farmers are eager to buy some inferior feed for cheap, which is very undesirable, so it is easy to make the pig malnutrition, resulting in poor pig growth and resistance, resulting in a large number of losses each year. Under high temperature conditions, the appetite and feed intake of pigs will decrease, and the growth of pigs will be seriously affected. Therefore, the feed nutrition level should be appropriately increased at high temperatures, and at the same time, the feeding methods should be adjusted to ensure that the pigs' morning and evening coolness are guaranteed. The pig is full and eats well. A small amount of baking soda can be added to the diet for finishing pigs, which can effectively increase appetite and prevent heat stroke. It is also possible to mix appropriate amounts of edible oil in pig feed to increase energy. Yang Heping believes that in hot environment, pigs need a part of vitamins to resist heat stress. Vitamin C is particularly important. It not only increases the resistance of pigs to infectious diseases and poisoning diseases, but also promotes healing of wounds and iron in the gut. absorb.
