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 in piglets. Therefore, how to effectively feed and manage pigs in order to enhance disease resistance and increase production capacity has become the key to the ability of pig farmers in the country to obtain high profits. Breeding technical experts reminded the farmers that the summer pigs need to pay special attention to the following three points:
temperature control
In order to ensure the normal production of pig farms in summer, effective temperature adjustment measures must be taken according to the temperature requirements of various types of herds, and the pig houses should be well ventilated to remove the heat in the pig houses and reduce the temperature in the pig houses. You can set a suitable inlet and outlet in the pig house. If the pig house has a large area, it is better to install a fan for ventilation and cooling. In recent years, domestic and foreign research and development of a variety of cooling facilities suitable for different groups of pigs have been widely used in large-scale pig production. There are many applications in addition to the fan there are sprinklers, wet curtains and so on. For unqualified farms, it is advisable to construct a shallow pool in the pigsty or directly splash water on the ground so that the pigs can lie in the water and cool down. Sprayers can also be used to spray the water on the pigs and absorb the pigs by vapor evaporation. The heat, while achieving the purpose of cooling. General piggery temperature should be controlled at about 25°C. It is best not to exceed 30°C. Most of the rural areas are open-type pig houses. Before the high temperature arrives, shelters should be shaded to prevent direct heat exposure from the sun leading to heat stroke. A certain amount of trees can also be planted around the pig house. Apart from purifying the air, To shading effect.
Health environment
Summer is the season when germs are very active. High temperature and high humidity can easily cause many 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. It is necessary to regularly clean sinks and troughs, remove excrement in time, and disinfect pig houses and surrounding sites from time to time. In the summer, there are more mosquitoes. If the pigs suffer from mosquito bites for a long time, it will not only affect production but also cause diseases. Therefore, insects must be exterminated 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 vaccination to prevent the occurrence of disease.
Nutritional conditions
Some farmers are greedy and cheap to buy some inferior feed, which is highly undesirable. It is very easy for the pig to become malnourished, resulting in poor growth and resistance to the pig, and there is a large amount of losses every year. Under high temperature conditions, the appetite and feed intake of pigs will decrease, and the growth of pigs will be seriously affected. Therefore, at high temperatures, the level of feed nutrition should be appropriately increased, and at the same time, the feeding methods should be adjusted, preferably in the morning and evening when it is cool. Ensure that pigs are full and eat well. A small amount of baking soda can be added to the diet of the finishing pigs, which can effectively promote appetite and prevent poisoning. It is also possible to mix appropriate amounts of edible oil in the pig feed to increase energy. In hot environments, pigs need vitamins to fight heat stress. Vitamin C is particularly important. It not only increases the resistance of pigs to infectious and poisoning diseases, but also promotes wound healing and iron absorption in the intestine.
