Winter Swine Temperature and Disinfection Management
Temperature has a close relationship with the growth and health of pigs. Therefore, in the feeding and management of pigs, attention is paid to the management and regulation of the temperature, and the creation of suitable growth and development temperatures is the necessary guarantee for the rapid growth or fattening of the pigs and the higher economic efficiency.
Ambient temperature
When the outside temperature is too low, in order to maintain a normal body temperature, the pig body must enhance the oxidative decomposition of the body's material and generate heat to supplement the loss of body heat. In general, when the temperature around the piglet is 20°C~26°C, the metabolic consumption is low and the growth and development are normal. However, large pigs have lower metabolic consumption at 15°C to 20°C, and increase their normal levels. Therefore, we must pay attention to do a good job in pig house cold insulation work (such as pigskin covered with plastic film, etc.), increase the temperature within the house, this will not only reduce the consumption of pig metabolism, but also can promote its growth and development.
Drinking water and food temperature
The temperature of drinking water and foodstuffs in winter pigs is also closely related to the growth and health of pigs. A nursing sow needs about 17.5 to 22.5 kilograms of water and food every day. If the water temperature and food temperature are 0°C, the temperature of these water and food should be raised to a body temperature of 39°C, and the pig's body must consume 682 to 878 thousand. The heat energy of the card also means that 0.5 to 0.75 kg of fine material is consumed daily to maintain body temperature, but not for lactation, growth and growth. Therefore, when feeding pigs in winter, it is necessary to frequently feed warm and warm water, which can reduce feed consumption and improve feeding efficiency.
Winter pigs should pay attention to ventilation and disinfection
In winter, the temperature is low, and many pig farmers often pay attention to the insulation of the pig house and neglect the ventilation and ventilation in the house, resulting in a large accumulation of pollutants in the air, causing the pig to become ill. Therefore, ventilation and disinfection of pigs during the winter cannot be ignored. Because the winter quarters need to be warmed and kept in a relatively closed environment, the contents of carbon monoxide, carbon dioxide and respirable particulate matter in the room are greatly increased. These harmful substances will lead to irritative injury and reduced immunity of the respiratory system of pigs, increase the chance of suffering from respiratory diseases, and will make the existing symptoms worse and difficult to cure.
In addition, the winter air in the house is too dry, bacteria and viruses floating in the air, and the chance of adsorbing on the organism is also greatly increased. This can easily lead to the proliferation of microorganisms and germs, which leads to many diseases of the pigs. Therefore, the pig house is timely. Ventilation and disinfection are important.
Ventilation disinfection of winter pig houses should pay attention to the following points:
Timely ventilation
When the temperature is relatively high at noon, the window is ventilated for 1 hour with a small gap. According to the survey, in the non-ventilated room, viral bacteria in the air can float for more than 30 hours. If the doors and windows are opened, the dirty air can drift away at any time, and the room can also get plenty of light, which can make it difficult for many viruses and germs to breed and reproduce.
Regular disinfection
Disinfecting the house on a regular basis can promote the robust growth of live pigs. Disinfectant drugs should be used in rotation. The dosage should be determined according to the instructions. Do not increase the dose without authorization. Before the disinfection, it must be thoroughly cleaned. When disinfecting, the ground should be like a layer of drizzle. It should not be too wet (the pig is easy to diarrhea) or it can not be too dry (does not achieve the function of disinfection). Every corner must be sterilized in place. When disinfecting, let the sprayer slowly drop the liquid above the pig and do not disinfect the pig.
Prevent freezing
Disinfection outside winter homes can be difficult, especially when a disinfectant pool is set up to enter the area and the passage of a pig house. Ice formation may occur in winter. For this case, sprinkle some salt in the disinfectant so that it will not freeze.
In addition, we must pay attention to the disinfectant in the disinfecting tank, so as to prevent the drug from being expired, resulting in a decrease in efficacy or failure.
