Winter pigs should pay attention to the pig's five fears
With the advent of winter, the climate becomes more and more cold. According to the seasonal characteristics, the farms should take corresponding measures to reduce the pig's stress and prevent accidents. The author now summarizes the need for attention in winter pigs as follows: I hope to help the majority of model households. First, the suitable growth temperature of cold pigs, 32 ~ 35 °C newborn piglets, nursery pigs 20 ~ 22 °C, pigs 15 ~ 20 °C. Low temperature has a more serious effect on pig growth weight gain. When the pighouse temperature is lower than the lower limit of the appropriate temperature, the daily weight gain is reduced by about 17 grams for each 1°C decrease, and if the temperature decreases below 4°C, the weight gain rate decreases by 500%. , increase the consumption of feed by more than 1 time. Second, the fear of tide suitable growth of different pigs and pigs, piglets 50 to 70?, 40 to 80 kg of finishing pigs 70?, 80 to 110 kg of finishing pigs 80?, breeding sows 55 to 80?. Piglets in pig houses with high relative humidity in winter have an average weight gain of about 48% lower than that of the control group, and piglets are prone to diarrhea, enteritis, paratyphoid induced piglets, and other diseases. It can be solved by ventilation, adding sunlight, and laying dry litter. Third, fear of cool when the water temperature, material temperature 0 °C, the water, material temperature rose to the body temperature 39 °C level, the pig body will consume 682 ~ 878 kcal of heat energy, which is equivalent to 0.5 ~ 0.75 kg per day Concentrates are consumed in vain to maintain body temperature. Therefore, raising piglets and sows in the winter, it is best to feed warm materials and warm water, the temperature of about 37 °C is appropriate. Fourth, afraid of the wind in the winter fear of "dragon style" and "thief wind", not only reduce the temperature, more likely to cause colds, stroke, rheumatism and other diseases. In the winter pig house, wind tunnels, hay curtains, and strict doors and windows must be blocked to prevent the “thief wind†from blowing in, affecting pig growth and development. Fifth, fear of disease If the winter pig house is low in temperature, high humidity, poor sanitation, and poor ventilation, pigs are prone to disease. Therefore, we must strengthen the feeding and management, keep the ventilation and cleanliness of the pens, clean and dry, and regularly disinfect the pens, at the same time, we must observe the form, observe the spirit, observe the food, watch the excrement, and observe the breathing. Once the pig is sick, Timely diagnosis and treatment as soon as possible.
