The scorching sun and the high temperatures in summer are a serious challenge for hog farms. When the pighouse temperature reaches above 30°C, pigs are prone to heat stroke, especially large pigs and pregnant sows. Reproductive disorders and the risk of disease will intensify. Therefore, it is important for the pig breeding farms (households) to do a good job of preventing heatstroke from cooling, which is very important for improving the breeding efficiency. Here are some ways to prevent heatstroke, for reference.
First, the roof cooling water. The method is: in the middle of the pig house roof, set up a plastic water pipe (both hard and soft), drill a small hole at each distance of 0.3 ~ 0.5m, connect one end of the water pipe to the water pipe and install the valve, and seal the other end. When opening the water inlet valve switch, the cool water is injected into the water pipe and spouted out through the holes, soaking the cooling tile surface, reducing the heat radiation, so as to achieve the purpose of cooling down. Can be on time when the most hot, open the valve at regular intervals, splashing water cooling. This method is simple and easy, and the cooling rate is quick and the effect is significant. In general, the farm has the ability and conditions to install, but more water is used. It is also possible to flush the roof tile surface directly with the high pressure water pipe at the time of high temperature every day.
Second, spray cooling within the house. This method is applicable to open pig houses such as pigs with relatively intensive pig finishing facilities, positioning pens for pregnant pigs or empty pigs for breeding pigs. Basically, the method is similar to the roof cooling water cooling device. The difference is that the plastic pipes used are all rigid pipes (or iron pipes) and are installed in the indoor half-space. The water pipes are not leaking holes but are installed with atomizing nozzles (heads). 0.5 to 1 m apart. When the water inlet valve is opened, clean water is sprayed from the nozzle at a uniform mist by means of pressure, and direct cooling and evaporation of the water mist absorb heat to achieve the purpose of cooling down. This method is easy to install, easy to operate, and the cooling rate is fast, the cooling effect is good, and the investment is not big. Generally the pig farm can be installed. However, due to the excessive humidity caused by this method, it is not suitable for use in closed pig houses such as delivery rooms and nursery homes. If connected with a disinfectant, it is an excellent house disinfection device. However, it should be noted that when installing, the nozzle opening needs to be placed above the water pipe, otherwise it is easy to clog the nozzle due to sediment deposition in the water.
Third, dripping cooling. This method is applicable to the cooling of sows that are giving birth to sows or positioning sows. The simplest method is to install a hard plastic tube above the head and neck of the sow (or positioning bar) sow, one end connected to the inlet pipe, and the upper valve installed, and the other end plugged, with the hose facing the neck of the sow. Drill a small hole. When the water inlet valve is opened, the clear water overflows from the tube hole and is dripped in the head, neck or neck of the sow. The cooling and evaporation of the drip water achieves the purpose of cooling the pig body. This method is simple and easy, not only can reduce the temperature of the sow but also keep the pig bed relatively dry, protect the piglets (boar bogey), is the method commonly used to reduce the temperature of sows in large-scale pig farm delivery room. This method has less investment, good effect, and is most suitable for the promotion and application of small and medium-sized pig farms. However, when the operation of the inlet valve is properly controlled, adjusted too much, a lot of water is ejected, the pig bed is wet, and the pig bed is too small, then the hole at the end of the water pipe does not drip out. All the small holes should be able to drip and keep the water in the control. Drops 30 to 60 times per minute is appropriate.
Fourth, the fan curtain cooling. Install high-power fans or exhaust fans in the breeding house, Yuemengsha, or nursery, and use air curtains to fan or draw air in the longitudinal direction to speed up air convection in the house to achieve cooling. Nursery and delivery rooms can be equipped with a moving head wall fan, but the installation position and height should be taken into account to prevent direct fanning of the piglets. This method is easy to operate, and has very good effect on the timely elimination of harmful vapors in the room. For those closed-type pig houses that lack local windows and harmful gases can not be eliminated through natural ventilation, it is undoubtedly an excellent response.
Fifth, add anti-heat stress drugs. Strengthen the body's ability to resist heat stress. Practice has proved that adding some anti-stress drugs to summer pig diets or drinking water to regulate the physiological functions of pigs is of great significance for preventing and reducing the harm caused by heat stress. Introducing a new product - Alvania: Olympus comes from Germany's precision stress nutrition, known as the stress firewall, can effectively fight high heat stress, reduce the impact of high fever delivery stress sow, piglets series! It is recommended that sows be used for 1000-1500 g/t of spices or drinking water 7 days before delivery and 7 days after delivery. In addition, it is recommended to use the full temperature above 32 degrees.
