Winter pigs focus on prevention

Winter pigs focus on prevention

(Summary description)The weather is cold in winter and spring, and most farmers raise pigs in open pens, often raising for 6-7 months or even more than 10 months before they can go out.

Information

The weather is cold in winter and spring, and most farmers raise pigs in open pens, often raising for 6-7 months or even more than 10 months before they can go out. In the winter and spring, the "eight prevention" pigs must be safe to survive the winter, grow fast, and have high benefits.

 

1. Windproof. In winter, the pighouse must block the wind tunnel, hang grass curtains, and paste windows to prevent air holes such as rat holes, cracks, gaps, and broken roofs in the pen from blowing into the wind through the hall and the wind of thieves. These two types of wind blow into the piggery, which not only lowers the temperature of the piggery, but also causes pig disease. Ventilation holes can be left at least one meter above the ground.

 

2, moisture-proof. Pig pen drying is one of the main measures to ensure the health of pigs. Air is a thermally conductive substance, and the more humid it is, the stronger its thermal conductivity. The faster the heat in the pig's body is dissipated. Pigs are cold and need to be stacked, crushing, crushing and even death, and epidemic disease is also easy to occur. Therefore, the perimeter should be on a regular attendance mat to ensure dryness, and pay attention to training pigs to urinate and urinate at a fixed point, and have a dry lying place.

 

3. Prevent low temperature. The optimal temperature for the growth of pigs is 15 degrees Celsius to 25 degrees Celsius, and the normal growth temperature should generally be above 8 degrees Celsius. In order to ensure the normal growth and development of pigs, the best method is to use warm sheds, that is, thick The plastic film completely covers the top of the circle. The cover must have a slope of about 30 degrees to facilitate daylighting. The temperature at noon circle can be deflated and ventilated and snow should be removed in time.

 

4, prevent cold food. In winter, pigs eat nothing more than to keep cold and gain weight, sows need to protect the normal growth and development of their fetuses, so it is necessary to appropriately increase energy feed when adding ingredients to increase their cold resistance. When feeding, it is best to mix and feed with raw food and dry feed. The water temperature should also be around 25 degrees Celsius when a small amount of water is required. In the case of thin feeding, the feed should be warm, and less frequent, and cold and frost-proof.

 

5, anti-chaotic feeding. Pigs must be fed with stable feeding quality and stable feeding time. The ingredients should be carried out according to different production performance and different growth stages. Avoid sudden changes in quality. If feed changes are needed, the amount and feeding time should be gradually changed.

 

6, anti-cold drink. Pigs have a high demand for water, which is important. When 10% of the body's water is lost, the pig will feel unwell and die. Therefore, pigs must be replenished with water at all times. If there is no water in the pen, pigs will eat snow, ice, and urine, which will inevitably cause digestive diseases or other diseases. Therefore, warm and clean drinking water should be constantly and constantly supplied to prevent both the patients and the pigs.

 

7, anti-bite frame. For pigs to grow normally, they must be fully nutrient in the feeding, and lack one or more ingredients. Not only is growth retarded, but bite-frame "evil" may also occur. Especially in winter, there is a shortage of green fodder. Large, therefore, it is necessary to supplement multivitamins, minerals, and trace elements in the feed, and to separate the strengths and weaknesses, size and circle, and castration in a timely manner.

 

8. Epidemic prevention. In winter and spring, the temperature is low and the air is dry. Digestive, respiratory, and infectious diseases of pigs are prone to occur. In order to maintain the healthy development of pig production, the pens must be kept clean, clean, and hygienic. For disinfection or spray disinfection, pigs must be vaccinated and resident drugs must be prepared for early isolation and early treatment if there is any disease.
