Several matters needing attention in the fine management of conservation pigs

In today's large-scale farms, most of them use excellent varieties with high production performance, and the relative litter size and survival rate of sows are relatively high, so what is the key stage related to the success of breeding? Practice shows that it is the conservation stage of piglets. The conservation phase is a transit station, which usually starts 10 days after weaning and ends with a weight of 30 kilograms. This is the key stage related to the benefit of the whole farm.

This stage is the turning point of pig physiology and individual change, from small to big, a process of gradual growth. This stage requires not only the management level of piglets but also the feeding mode of fattening pigs, especially the digestive system changes greatly, the nutrition level decreases from the early feed of piglets which is easy to digest and absorbs to the later feed of piglets, and the feed intake of piglets also increases gradually, which is a stage that needs key management and needs special personnel for feeding and management.

The feeding at this stage is relatively strict, pay attention to grasp the timing and interval of feeding. At this time, the feeding mode can be changed from free feeding to regular feeding, or from regular feeding to free feeding, or to continue free feeding, which is relatively stressful to pigs, but conducive to the rapid development of intestinal tract. Also pay attention to the quality of feed, whether the nutrition is comprehensive and easy to absorb, high quality, no mildew, good palatability. At the same time, pay attention to the feeding method, feed less frequently, add once every 40 minutes during the day and 2 hours at night. The amount of feed added each time is determined by the size and feed intake of the pig.

At this stage, the temperature is relatively strict, which requires that the temperature be kept at 18 mi 20 degrees, the relative humidity at 50 mi 65%, and the ventilation is good, and the culture density should not be too large to ensure good lighting. To create a quiet, warm and comfortable growing environment for nursing pigs.

Disease prevention is also an important task at this stage. The change of environment, the change of nutrition and the change of feeding mode will all become the inducement of disease. The first problem to be solved at this stage is parasites. Purify the parasites inside and outside the pig, reduce the nutrient loss of feed, improve the utilization rate of feed, improve production performance and enhance physique. Secondly, at this stage, the most important thing to pay attention to is the epidemic prevention of classical swine fever, pay attention to health care, for respiratory tract, digestive tract, virus diseases, epidemics, etc., choose high-quality drugs to add regularly. Health care can prevent and reduce the occurrence of diseases and improve the health and breeding rate of pigs. Prepare for the rapid growth of fattening pigs in the later stage.

Pay attention to daily management, and the hygiene of the enclosure is also an important factor related to the success of conservation. At present, most of the nursery construction adopts high-bed leaky floor, the surface is more likely to be contaminated, and the pigs are active. Regular walking will increase the polluted area and increase the occurrence of intestinal diseases such as E. coli. As the space of the nursery is relatively small, but also to maintain temperature, humidity and ventilation, it is difficult to clean the nursery thoroughly, the harmful gas content in the enclosure will increase, and the incidence of respiratory diseases will increase. Therefore, the sanitary work of the enclosure is also a focus, often using disinfectants to scrub the care bed, wall, floor, corridor, material trough, sink and so on. Increase ventilation, reduce the content of harmful gases in the enclosure, ensure air quality, and disinfect 2mi 3 times a week. It is also important to note that rodent control, mosquito and fly control efforts reduce the spread of disease. Establishing a good habit of three-point positioning for pigs will not only save labor but also help to maintain the hygiene of the enclosure.

Generally speaking, the fattening stage is a stage that needs to be paid more attention to, a stage that requires fine management, and it is also the guarantee of farm profits at this stage, which should become the focus of farm work. According to the key points of feeding and management in the conservation stage, Weiyuan recommended a health care scheme: Zhongwei fluorite 100 g + Yinqiao San 100 g + Olai Ke 200 g / 100 kg feed, starting from being transferred to the nursery and used continuously for 7 days. Three weeks later, Miaolisu 125g + MoWeixin 400g + Olai 500g / 1000 kg feed was used continuously for 7 days, once every three weeks. The pigs were dewormed once at the age of 50 days, 1000 grams of Jinywei / 1000 kilograms of feed for 7 days. At the age of 60-65 days, the pigs were immunized with classical swine fever once, and the nursing house was disinfected with Jin Weikang three times a week.

It is more important to do a good job of prevention and health care than to reduce the losses caused by disease.
