Temperature and disinfection management of raising pigs in winter

? How to adjust the temperature of raising pigs in winter?

Temperature is closely related to the growth, development and health of pigs. Therefore, in the feeding and management of pigs, paying attention to the management and regulation of temperature and creating a suitable temperature for its growth and development is a necessary guarantee to promote its rapid growth or fattening and obtain higher economic benefits.

? Ambient temperature

When the external temperature is too low, in order to maintain normal body temperature, pigs must enhance the oxidation and decomposition of substances in the body to produce heat to supplement the loss of body heat. Generally speaking, when the temperature around the piglet is 20 ℃ ~ 26 ℃, the metabolic consumption is low and the growth and development is normal. However, the consumption of big pigs was lower and the fat gain was normal in the period of 15 ℃ ~ 20 ℃. Therefore, we should pay attention to the cold protection and heat preservation of the pig house (such as covering the pig house with plastic film, etc.) and increase the temperature in the house, which can not only reduce the metabolic consumption of pigs, but also promote their growth and development and fat gain.

? Drinking water and food temperature

The temperature of drinking water and food of pigs in winter is also closely related to the growth, development and health of pigs. A lactating sow needs about 17.5-22.5 kg of water and food every day. If the water temperature and food temperature are 0 ℃, to raise the water and food temperature to the level of body temperature 39 ℃, the pig will consume 682-878 kcal of heat, that is, 0.5-0.75 kg concentrate per day will be wasted in maintaining body temperature, but not for lactation, growth and fat gain. Therefore, when feeding pigs in winter, we should often feed warm food and warm water, which can reduce feed consumption and improve feeding efficiency.

Attention should be paid to ventilation and disinfection in raising pigs in winter

Because of the low temperature in winter, many pig farmers often only pay attention to the heat preservation of the pig house and ignore the ventilation in the house, resulting in a large accumulation of pollutants in the air, resulting in pig disease. Therefore, the ventilation and disinfection of pigs in winter can not be ignored. Because the winter enclosure needs to warm up and stay warm, it is in a relatively closed environment, which will greatly increase the content of carbon monoxide, carbon dioxide and respirable particles in the room. These harmful substances will lead to irritant damage to the respiratory system and decrease of immunity in pigs, increase the chance of suffering from respiratory diseases, and aggravate the symptoms of existing diseases and are difficult to cure.

In addition, the air in the house is too dry in winter, and the bacteria and viruses floating in the air are also much more likely to be adsorbed on the body, which can easily lead to the proliferation of microorganisms and bacteria, thus leading to pigs suffering from a variety of diseases. therefore, timely ventilation and disinfection are very important in pig farms.

The ventilation and disinfection of pig pens in winter should mainly pay attention to the following points:

? Timely ventilation

When the temperature is relatively high at noon, open a small gap in the window for ventilation for 1 hour. According to the survey, in the room with poor ventilation, the virus and bacterial droplets in the air can float for more than 30 hours. If the doors and windows are always open for air, the dirty air can float away at any time, and the room also gets enough light, which can make it difficult for a variety of viruses and germs to breed and reproduce.

? Regular disinfection

Regular disinfection in the house can promote the healthy growth of pigs. Disinfection drugs should be used in rotation, the dosage should be determined according to the instructions, do not increase the dose without authorization. Must be thoroughly cleaned before disinfection, disinfection to make the ground like a drizzle, not too wet (pigs prone to diarrhea) can not be too dry (can not play the role of disinfection), every corner should be disinfected in place. When disinfection, let the sprinkler on the top of the pig to slowly drop the liquid, do not disinfect the pig.

Prevent icing

It is difficult to disinfect outside the house in winter, especially the disinfection pool set up when entering the farm area and the pigsty, which may freeze in winter. In this case, you can sprinkle some salt in the disinfectant so that it will not freeze.

In addition, we should also pay attention to frequently change the disinfectant in the disinfection pool to prevent the expiration of the drug to reduce or invalidate the efficacy.
