In winter, the temperature becomes cold, the temperature difference between day and night is large, and the air is dry, which causes strong cold stress to pigs. The disease resistance and immunity of pigs decrease, which is the season of high incidence of diseases. In addition, pigs grow slowly in winter, feed remuneration decreases, and survival rates decrease, which seriously affects the economic benefits of pig breeding. How to improve pig farm efficiency in winter? Strengthening feeding and management strategies is important!

The harm of low temperature to pigs


When growing pigs are exposed to cold stress, the pig body can dissipate too much heat, and the body's heat production cannot fully compensate in time, making the pigs prone to catching colds. At the same time, the cold can prompt the pigs to reflexively increase their feed intake and water drinking. It also decreases, affecting the balance of water and salt metabolism, reducing the resistance of pigs, and increasing the risk of infectious diseases (respiratory and intestinal diseases).


Delays the first estrus period of gilts, prolongs the interval between estrus and inconspicuous estrus of multiparous sows; the climate is dry in winter, and pregnant sows are prone to constipation, cracked hoofs, and skin cracks; due to cold resistance, pregnant sows are prone to emaciation and malnutrition , causing sow hypothermia syndrome, hind limb weakness, small birth weight of piglets, many weak piglets, and poor vitality. Increased sebum and parasites compete for nutrients, and lactation capacity decreases after childbirth. Cold stress in boars can lead to a decrease in sperm motility and affect the conception rate of sows.


Too low ambient temperature will lead to the redistribution of nutrient metabolism in pigs. That is, part of the nutrition is used to resist cold, resulting in slow or stopped growth (on the surface, feed intake increases, but in fact, the animal's anti-stress nutritional consumption and maintenance needs increase, the pig's weight gain and feed conversion rate decrease, and the production efficiency reduce).

Strengthen feeding management to deal with cold stress


Environmental control: cold protection and warmth, temperature, humidity, density, and air quality control, that is, cold protection and warmth, because pigs are warm-blooded animals and are very sensitive to environmental temperature changes. The health, growth rate, and feed conversion rate of the pig herd are closely related to the environmental temperature. .


Control humidity: The floor of the pig house should be dry. The greater the humidity, the faster the heat dissipation from the pig's body surface. If the humidity is not well controlled, sows are prone to cracked hoofs, arthritis, and even rheumatism; piglets have reduced resistance, which can easily induce respiratory diseases, diarrhea, and rough coats. Low temperature and high humidity also greatly increase the maintenance requirements of pigs and slow their growth rate. decline.


Proper ventilation: Due to the strong airtightness of pig houses for heat preservation in winter, the air is dry, dusty, heavy in ammonia, and the air quality is poor, which can easily cause respiratory diseases. Mainly for instant ventilation and air exchange.


Feed nutrition: Increase the energy level of the diet, appropriately reduce the intake of protein levels, and increase the feeding amount (number of meals): Since the days are short and the nights are long in winter, the fasting time is longer at night, so the feeding amount can be appropriately increased at night to It can make up for the weight deficit caused by pig body fat and intramuscular metabolic heat production due to low temperature.


Feeding management: segmented and batched management, stage subdivision, and refined management. Pigs at each stage have different physiological characteristics and require different nutrients, and the conditions and health of the pig houses at each stage are different, so each stage has different physiological characteristics. The feeding and management of pig herds during the pig stage are also different. For pig farms, winter is a critical period that tests the production and management level of pig farms. If pigs are raised well in winter and spring, there will be fewer pig diseases in the coming summer.


Disease prevention and control: The overall focus of pig raising in winter lies in the reasonable combination of feed nutrition, appropriate temperature and good ventilation in the pig house, reasonable vaccine immunization and correct drug health care. In winter, the focus is on purifying blue ears and rings, and preventing influenza, diarrhea, and non-infectious diseases. plague and foot-and-mouth disease, improve the pig's own immunity and deal with them in a timely manner according to the conditions of your own pig farm.
