Pigs
1. Increase the temperature of the pig house and pay attention to cold protection and warmth. Increasing the temperature of the pig house and preventing cold and keeping warm is a very important part of @#@227@#@ in winter.
There are many ways to increase the temperature of the pig house, but there are four simple, economical and practical methods. First, cover an open pig house with plastic film. It is best to cover it with double-layer plastic film; this method is suitable for fattening pig houses and non-lactating sow houses. Second, use boiler-type heating in closed pig-raising workshops. Third, use heating plus plastic film covering in open pig houses. Fourth, use heating plus electric heaters, suitable for lactating sow houses. In addition, for newborn piglets, heating equipment should be used to keep the farrowing house temperature at 22°C-25°C. At the same time, heating equipment such as piglet electric heating plates and infrared bulbs should also be selected to provide a heat source for piglet nursery boxes (the temperature of the nursery box should be kept at 33°C-35°C). However, it should be noted that when using heating equipment fueled by coal, attention should be paid to whether the coal is fully burned and whether the flue is unobstructed, so as to avoid carbon monoxide poisoning in the pig herd.
2. Keep the house sanitary, dry and with fresh air.
On the premise of maintaining temperature, strengthen ventilation, reduce humidity in the house, and use as little water as possible to wash the pens; frequently clean the manure in the house, maintain a good sanitary environment, reduce the concentration of harmful gases, and keep the air in the house as fresh as possible. Strengthen bedding management; bedding should be removed and replaced frequently, and should be replaced in time when it is damp and smells strongly.
3. Seal the pig house to prevent "cross-ventilation" and "evil wind."
Seal the windows of the pig house, open the pig house doors as little as possible, and if conditions permit, install a suspended ceiling in the pig house to prevent cold air from entering the pig house.
4. Feed reasonably and strengthen nutrition.
According to the nutritional needs of pigs at different stages, provide high-quality complete compound feed with complete nutrition for the corresponding stage; improve feeding methods to promote the herd's digestion and absorption of the diet, use warm water to mix feed for feeding, and add an extra nighttime feeding in the evening to increase appetite; feed more green forage, add multivitamins to drinking water, and reduce stress factors. Pay attention to feed storage, do not feed moldy and spoiled feed, and prevent poisoning of pigs or miscarriage of pregnant sows. Do a good job in iron supplementation, selenium supplementation, water supplementation, starter feeding and feed work for weaned piglets.
5. Appropriately increase stocking density
When stocking density is high, the floor area occupied by each pig is reduced, and they can warm each other by lying close together. At the same time, when pig stocking density is high, their bodies also release more heat, which helps increase the temperature in the house.
6. Do a good job in the environmental sanitation around the pig farm.
Carry out regular disinfection to kill pathogens in the environment. For sick pigs, symptomatic treatment should be carried out on the premise of doing a good job in heat preservation.
