Heatstroke prevention and cooling measures in hot season

Posted on

During the hot season, the heatstroke prevention and cooling measures are hot in summer, which results in the decline of the immunity of the pigs and the occurrence of diseases. Therefore, the majority of farmers must do the heatstroke cooling work of the pens to avoid economic losses caused by the heat. 1, to enhance the thermal insulation performance of pigs: General pigs are made of clay bricks. Roof tiles are generally made of earth tiles or asbestos tiles, which do not provide insulation. Most of the rural pigs are open-type pigs, and the temperature in the house is difficult to control. Before the high temperature arrives, a layer of thick straw, wheat straw and other heat insulation materials can be placed on the top of the pig house to build a pergola above the open space of the house, and plant vines (loof gossypium, gourd, grape, etc.) before the house. Improve the insulation performance of the pig house. In order to improve the microclimate around the house, broad-leaved trees are planted around the pig house. In addition, a layer of fresh lime milk can be applied to the inside and outside walls of the pig house to reduce the heat radiation from sunlight and provide good disinfection. .
2, to strengthen convection, ventilation and cooling: farm site selection must be selected in an open, well-ventilated place, the height of the pig house should be maintained at 3m or more. Before and after the building should be staggered left and right, conducive to ventilation, the direction of the pighouse should be to minimize direct sunlight. When the hot season arrives. Open all ventilation holes in the pig house (the “four windows” required by the Kinpo fermentation bed: windows, skylights, underground windows, exhaust fans). Minimize the foul gas in the pens and create a cool and comfortable environment for the pigs. Therefore, it is required that a qualified pig farm can install a ventilation fan or an electric fan on the wall of the house to accelerate the air circulation and achieve a cooling effect.
3, water cooling: generally spray cooling, water cooling and dripping cooling. The Jinbao fermentation bed is a dry-sauce fermentation, so “we are not afraid of dryness”. If the house is really hot, dusting has affected the normal activities of the pig. At this time, spray some water mist, that is dust It's cool again. Professional breeding households can also choose one of the methods according to their own conditions, but at the same time should pay attention to the pig's physical condition and the normal operation of the Goldfish fermentation bed.
4. Strengthen feeding management: Decreasing the rearing density is not only beneficial to the heat dissipation of the pig body but also reduces the amount of heat that is distributed to the pig house. The pig house must always be kept clean. Disinfect regularly. Prevent the occurrence of infectious diseases. Feeding pigs should avoid the hottest hours in the afternoon. To reduce the pig's activity during the hottest hours. Drink pigs once a day O. 5% of the salt water, to provide ample green and juicy feed, keep enough fresh cool water in the trough.
5, heatstroke prevention medication: can be added in the feed or drinking water amount of heat Jieshu, Shengjinzhike drugs. Such as plantain l00g, decoction juice feeding materials: mung bean boiled into rotten porridge, wait until cool after feeding; white lentils 20 ~ 25g, decoction juice feeding clothes; fresh watermelon rind 2 000g, erosion Add 100 g of white sugar and stir evenly to serve; 250 to 500 mL of vinegar or sauerkraut juice is mixed in the feed to provide good heatstroke protection. Finally, I wish the pig farmers of the majority of farmers can spend the summer and achieve better economic benefits.

Most products of Fluorine-Containing Benzaldehyde are a pale yellow liquid. They are playing an important role in fine chemical intermediates, is used as the main raw material for the synthesis of a variety of pesticides, pharmaceuticals, surfactants, polymer monomer mildew. As used in medicine synthesis antihypertensive drugs, antipyretic analgesic anti-inflammatory drugs, anti-cancer drugs, muscle relaxation drugs for synthesizing fluorine cypermethrin, fluorine chlorobenzene daisy cool in pesticides, fluoride and styrene, wherein the polymer of styrene monomer to fluorine can be widely used in the manufacture of the recording material, a thermoplastic resin coating, liquid crystal materials. Currently new miticide is effective pesticide products which is the main raw material of Fluorine-Containing Benzaldehyde.
