Pig farmers must know how to manage sows in the high temperature season?

We must change the mode and way of management, we must give the pigs some grass feed when it is cool, we must regularly sterilize the pigsty, disinfect and cool down, and then we must let the pigs drink more water to reduce heat radiation, the dormitory must have some thermal insulation materials, we must insist on vaccination, and then we must improve the concentration of feed, and stabilize the endocrine and nervous system of pigs.

In the hot season, attention should be paid to the sow's escape from the heat, not to let the sow get exposed to the sun, and attention should also be paid to ventilation in the pigsty. And to carry out overall disinfection, the sow should also be bathed frequently.

Be sure to pay attention to ventilation, pay attention to cooling, and sprinkle some water regularly. Some fans can be installed appropriately. Pay attention to sun protection.

Precautions for breeding sows in high temperature seasons: drinking water for sows, ventilation of pig houses, and work and rest arrangements. In the high temperature season, it is necessary to pay attention to ensure enough cool and clean drinking water for sows, the water temperature is best at 10 degrees Celsius, and a large amount of body heat is taken away by drinking a lot of water, which is conducive to cooling sows.

In the high temperature of summer, avoid stressful activities such as driving pigs and seedlings at noon, and use the cool time in the morning and evening as much as possible.

In the high temperature season, we should pay attention to cooling the pigs, maintain the temperature of the pig house, and give them more nutrients to eat the forage, so that the pigs can grow faster.

In the hot season, these sows should be placed in a cooler place, and the temperature must be paid attention to to be able to manage the sows well.

Ensure enough cool and clean drinking water: the most suitable water temperature for sows in summer is 10 degrees Celsius, through a large amount of water drinking, take away a lot of body heat, and the feed water ratio may be increased to more than 1:5 at high temperatures.

You can do some shade with the rental shed, and you can give the pigs some slightly cooler water, so be sure to ventilate as soon as possible.

We must cool down the pigs, we must spray some water frequently, and we must give the pigs more water, or we can install an electric fan in the place where the pigs live, so that the pigs will not be affected by the heat.

During the hot season, these sows should be fed more water, because the climate at this time is particularly dry and hot.

Pig environmental sanitation in summer is the key, and it is necessary to clean up the barn in time to prevent manure from filling the circle; Effectively kill mosquitoes and flies in the house, so that the pigs can rest fully; Reasonable and effective sanitation and disinfection of the pen to prevent the immune balance of pigs from being broken; Do a good job of preventing cooling and timely ventilation management to prevent heat stress. Reasonably adjust and improve the nutritional structure of the feed, it is best to add some vitamins and other related nutrients, especially for pregnant and lactating sows, it is necessary to make up for various body needs, and take appropriate corresponding measures, otherwise it is very easy to produce too long farrowing, stillbirth and weak piglets.

On the roof of the pig farm, cover it with white plastic sheeting, which can reflect the sunlight on the roof, reduce the heating area of the roofing material, and thus ensure the coolness of the pigsty. The installation of cooling equipment such as sprinklers, exhaust fans, air conditioners, etc., can effectively reduce the temperature in the pig farm. For example, in the morning, noon and evening to water the pigs once, when the pigs have heat stroke, the pig house should be ventilated as soon as possible, or the pigs should be transferred to a cool place, with cold water to apply the head and chest, if necessary, the cold salt water can be used repeated enema.

If the pig is inconvenient to move, a powerful fan can be placed next to the pig to blow the pig. 2. Timely bleedlet 100 to 300 ml at the tip of the tail and ear, and at the same time inject an appropriate amount of 5% sugar and salt water to prevent dehydration.

The least thing to do is to get the ventilation system and sun protection system right. The purpose of ventilation is to ensure that the air around the pig flows without causing excessive humidity; The purpose of the sunscreen system is to prevent the pigs from being exposed to the sun directly, causing the temperature in the pen to rise.

Adjust the diet to reduce the protein and sugar content of the diet appropriately and reduce the production of calories. At the same time, a certain amount of vitamins can be added to the diet to reduce stress and promote stable metabolism. Reduce the feeding density, clean the enclosure in time, and strengthen ventilation.

Pigs should be watered more, fed more water, cleaned well, vaccinated pigs in time, and given pigs more good food.

It is important to cool the pigs by reducing the feeding density or to increase the ventilation in the pen.

Regular sterilization and disinfection, prevention of pests and diseases, and a healthy growth environment for pigs.

After autumn, the temperature difference between day and night increases, and the pig farm should pay attention to keeping warm, strengthen the maintenance of doors and windows, and prevent the invasion of bad winds at night. Swine flu has obvious seasonality, often occurs in autumn, winter and spring when the temperature changes abruptly, especially when it is wet and rainy, it is more likely to occur. Transmission through feces mainly through the respiratory tract, poor feeding management, fatigue and congestion during long-distance transportation are all triggers for the onset of swine flu.

The main symptoms of swine flu are accompanied by high body temperature, generally up to 40 to 42 degrees Celsius, depressed, not moving, loss of appetite or not eating, less stool, only some granular fecal balls, little urine and yellow.

Most pigs breathe faster and cough. A small percentage of pigs are flushed, and there is a viscous fluid coming out of the eyes and nose. In the absence of complications, the recovery is quick and lasts about 1 week.

If the resistance of the disease is reduced, secondary infection with other bacteria (such as pasteurella, streptococcus, etc.) can aggravate the disease, bronchopneumonia and death. At the same time, the pig farm was fully disinfected with 2% caustic soda, and the feeding density was appropriately adjusted. Place the pigs in a warm, clean, and wind-free place to strengthen the cleaning of the pig house.

In addition to providing enough clean drinking water, the pigs are also properly fed some fresh and tender green feed to allow them to eat freely. Due to the large temperature difference between morning and evening in autumn, it is easy to induce piglets to catch colds, and even cause large-scale infectious diseases in serious cases, so pigs must do a good job of epidemic prevention in autumn in accordance with epidemic prevention regulations. Special attention should be paid to infectious diseases such as swine fever, swine lung disease, swine influenza, erythroderma, and swine cold, and to prevent the occurrence of swine streptococcal disease, infectious gastroenteritis, epidemic diarrhea and other diseases.

In the fall, consider increasing the dose, increasing the number of injections, or using a highly effective vaccine.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

When raising pigs, we must choose the right feed, and then we should also learn professional breeding techniques, and we should reasonably control the temperature, and the temperature should be controlled at about 20, but we must feed the forage in time, and we need to feed the pigs in a timely manner.

Attention should be paid to strengthening the repair of doors and windows, and attention should also be paid to keeping warm. Dispose of manure in a timely manner. Feed management should be done well, and the most important job in autumn is to keep warm. Do not be damp or cold.

It is necessary to pay attention to the warmth of the pigs, the nutrition must be very rich, and the movement of the pigs must be paid attention to often, and the environment must be good, and the cleaning must be very clean, so as to save the virus.

Be sure to keep the pig warm, the nutrition must be very rich, you must always pay attention to the dynamics of the pig, and the environment must be good, and it must be cleaned very clean, so as not to be infected with the virus.

In winter, if the temperature of the pig house is greatly improved, it is recommended to choose a professional radiator, which can not only ensure the growth of piglets but also be economical. The finned tube radiator for steam is often used for heating in large places such as industrial plants and greenhouses, and the heating temperature can reach 180. Finned tube radiators have high heating efficiency and can meet the heat needs of large places, so they are usually used in heating systems in large buildings.

Finned tube radiator.

Some people feel that the high-frequency welding electric finned tube radiator should strictly prohibit the production of connectors, the reason is that the connector seriously affects the thermal conductivity characteristics of the finned tube radiator: another part of the people feel that the number of high-frequency welding finned connectors does not need to be limited, as long as the joint is firmly connected, the generation of the connector has a small impact on the thermal conductivity of the finned tube radiator, which can be ignored. The specific situation in our country is that the production and manufacturing of aluminum strips and the production and manufacturing of finned tube radiators are not matched, and after each tube is wound, there will be aluminum strips that are absolutely different and not enough to wind a tube

Finned tube radiator.

In the past, people said that there were different opinions on whether the fin connector of the high-frequency welded electric finned tube radiator had a direct impact on the heat exchange performance index, and the experiment should be carried out on 9 finned tube radiators containing different number of connectors. The results show that the more connectors, the greater the impact on heat transfer performance. Therefore, the ubiquity of connectors should be prevented or reduced.

Winter pigs should pay attention to low temperature, anti-slip, windproof, and can not provide cold feed and cold water for pigs when feeding, nor can they change the feed, so as to avoid frost damage to pigs, it is best to provide stable feed for pigs, and spread grass mats in the pigsty to keep warm, but also to feed the feed after using warm water.

1. Food selection

In winter, pigs can not change their feed frequently, and can not use cold feed or cold drinking water when feeding, so as not to catch a cold pig. It is best to provide stable energy feed for pigs after winter, and provide the feed with warm water to the pigs so that they can survive the winter.

2. Warm treatment

In winter, pigs should pay attention to low temperatures. Pigs are suitable for growing in a warm environment, and the temperature is too low to cause pigs to suffer from frost damage, so after the arrival of winter, a heater or coal stove should be installed in the pigsty to keep the room warm, but the coal stove should be ventilated regularly to avoid poisoning.

3. Wind prevention measures

In winter, pigs should pay attention to windproof and avoid cold wind in the pigsty, resulting in a decrease in temperature, so after winter, the vents in the pigsty should be sealed with plastic film, wooden boards and iron nails, and cotton curtains should be hung at the entrance and exit to avoid cold wind blowing in.

4. Lay a straw mat

In winter, pigs should pay attention to non-slip. If the ground of the pigsty is too wet in winter, it will freeze, causing the pig to slip and fall, at this time, lay a straw mat or straw in the pigsty to isolate the pig from direct contact with the ground, and absorb the moisture in the pigsty, so as to achieve the purpose of keeping it dry.
