In summer, the temperature is high and the humidity is high. The incidence of pigs rises significantly and the ambient temperature is too high. Pigs increase respiratory rate in order to dissipate body heat, affect metabolism, reduce appetite, and reduce productivity. Therefore, in the summer, it is necessary to strengthen feeding and management, improve the feeding environment, and scientifically and reasonably match feed, and actively implement disease prevention and control in order to enhance its resistance to disease and increase production capacity. Summer cooling Visor. The piggery should be built in an open and ventilated area. Before the high temperature season comes, a pergola should be built on the roof of the pig house. Planting some trees and flowers around it will not only beautify the environment but also block the sunlight and reduce the temperature of the house. ventilation. In the high temperature environment, the pig's blood flows to the skin and the body surface temperature of the pig increases. The enhanced ventilation not only enhances the speed at which heat is taken away from the body surface, but also helps to eliminate harmful gases in the summer housing. It is recommended that qualified farms (households) should adopt mechanical ventilation and install ceiling fans or blowers to ensure that the 24-hour air circulation in pig houses is smooth. Drinking water. During the hot summer, the pig's drinking water increased greatly. Ensuring adequate drinking water is very important for relieving heat stress. Make sure the pigs often drink water. The temperature of the drinking water should be kept as cool as possible. The water directly from the underground deep wells is best to prevent the water pipes and the water tanks from being exposed to the sun, resulting in too hot drinking water. When the temperature is too high, the water can be sprayed on the roof of the pig body (except the branch house) at regular intervals. Generally when the pighouse temperature is above 30°C, spray water once every hour to cool down once. For grow-finishing pigs, deep well water can be sprayed directly onto the pig to cool down, but be careful not to spray the pig's head. The free-range households can build a shallow pool in the corner of the pig house so that the pig can freely soak in the pool. Reduce heat radiation. Heat radiation is an important source of heat for increasing pig body heat. In summer, the sun must be protected from direct sunlight on the pig's body, and the roof of the pig house can be insulated. For example, the ceiling of the pig house can be used for planting tall trees to reduce the radiant heat of the roof. In short, take measures to prevent the roof from getting too hot. Strengthen feeding management Under high temperature conditions, the pig's appetite and feed intake are significantly reduced, directly affecting the pig's production performance, especially for the nursing sows. Therefore, except for piglets in summer, the level of protein and amino acids in feed grains should be increased, the amount of vitamins should be increased, and the proportion of indigestible and heat-producing roughage should be reduced as much as possible; no feeding or less feeding of grass powder, reducing bran, etc. At the same time, as far as possible, use wet feeds to feed pigs. Feeding time should be selected during the cool period of the day. The pighouse temperature is very high at noon and afternoon and the pigs have no appetite. It is advisable to feed the pigs early in the morning, feed them at noon, feed some pigs in the late afternoon, feed them once at night, add less to the ground, and don't have leftovers in the troughs. Enzyme preparations can also be added to the feed to increase digestibility and reduce heat stress. Strengthening health management Due to its special environmental factors, farms have more turbid materials and there are health corners, which create conditions for the breeding of flies and their eggs. Therefore, the mosquitoes and flies in the farm place insect eggs and other harmful substances into the feed and other substances. At the same time, causing diseases in the pig herds is also a “good†medium for the spread of diseases in pigs. Therefore, mosquitoes and flies must be killed in summer. (1) Clean the troughs and sinks once a day and remove the excreta, pigs and surrounding areas in a planned manner. The pen homes and feeding implements are sterilized once every 3 days to 5 days. The surrounding environment is sterilized once every half a month. You can use 1% for Suer, 10% quicklime milk, and 2% caustic soda. The pig body can be sprayed with 5% carbolic acid. (2) Mosquito and flies are the carriers of many infectious diseases, such as highly pathogenic blue ear disease, eperythrozoonosis, Japanese encephalitis, swine toxoplasmosis, circovirus disease, rickets, and salmonellosis. , swine dysentery, transmissible gastroenteritis, pseudorabies, tsutsugamushi disease, brucellosis, swine fever, etc., so pay attention to drive. Can be used 0.1% trichlorfon fluid, but also buy special insecticides. Doors and windows to install anti-mosquito gauze. Reduce other stress The pig's anti-stress ability is very low, and the stress makes the pig's secretion of stress hormones (such as adrenocorticotropic hormone) increase, which not only increases the pig's heat load, but also reduces the pig's immunity. Minimize all kinds of stress on pigs, such as rough treatment of pigs, frequent mixing of groups, feeding time, and sudden changes in feed, personnel, and the environment. In short, the high temperature and humidity in summer, if the feeding environment is not good, it will lead to decreased resistance of the pig body, and it is easy to be attacked by pathogens. Therefore, pig raising in the summer should be strengthened with feeding and management, with a reasonable diet to improve the pig raising environment. Pay attention to the cooling of the sun, clean the environment, regularly sterilize the environment, kill mosquitoes, flies and surface parasites. Strengthen the immunization of pigs and do a good job of procedural immunization work according to the local epidemic. It was found that the pigs were immediately isolated and treated. The medication was administered according to the course of treatment, and high sensitivity drugs were alternately used to avoid drug resistance. Dead pigs are buried or incinerated to control the spread of the disease. We're professional Resectoscope Electrode
