The fattening pig is the best management stage for a breeding farm. It is the stage where the pigs have the lowest environmental requirements and the final sprint stage for the pig farm to make money. The performance of the finishing pig determines the profit of a farm. . However, in general, pig farms tend to focus on the management of sows, breeding pigs or suckling piglets, but not the management of finishing pigs. For example, most pig farms have the simplest facilities for fattening pigs, and the feed has the lowest nutritional value. Sometimes even the moldy feed is fed to the finishing pigs, which may lead to slow growth and increased incidence of finishing pigs.

There are two main types of diseases that often occur in fattening pigs: respiratory disease syndrome and diarrhea caused by various causes (mainly colitis, swine dysentery, colitis, ileitis, salmonella enteritis, etc.). In addition, swine fever, toxoplasmosis, atrophic rhinitis, etc. often occur in some farms. If the management of the fattening herd is not strengthened, these diseases will not only affect the sales of the breeding pigs, but also The management of the farm will also create a vicious circle.

Therefore, the breeding and management of fattening pigs should be strengthened, and it is impossible to neglect this situation and cause unnecessary losses.

Nutritional full-price feed ratio

The feed cost of growing and finishing pigs accounts for nearly 70% of the total feed cost of the farm. Therefore, it is most feasible to save feed in the fattening stage, but the growth rate of pigs in the fattening stage is fast, and the development of the body and internal organs is not coordinated. Its nutritional needs are high. If the nutrition is not enough at this time, it is easy to have problems such as low immunity. In particular, pigs can reduce the feed intake of pigs during transfer or long-distance transportation. At this time, pigs have higher demand for nutrients, especially vitamins. If you do not increase the nutrition of fattening pigs, it will cause relative nutrition. lack of. The feed intake in the fattening stage is the largest, and the feed conversion rate will directly affect the feed consumption and economic benefits of the whole farm. It is not the cheaper and cheaper the feed. The key is to ensure the quality of the feed, especially the contamination of mycotoxins. If the pig is sick or grows due to feed, and thus affects the economic benefits of the farm, it will be worth the loss.

Farming management mode

All-in and all-out is an important way for pig farms to control infectious diseases. Most of the farms are designed according to the all-in and all-out mode. However, when the pigs are good, the blind expansion will lead to an increase in density. If the complete all-in and out are not completed, it will easily cause the pig house. Disease cycle. Because the pigs left in the pig house are often poorly grown pigs, sick pigs or pathogen carriers. After the next batch of pigs come in, these pigs can be used as infectious sources to infect new pigs. It may be ill, slow to grow, or become a stiff pig, and it will remain as a new source of infection when it is transferred.

If the farm can do all the way, it will avoid these phenomena, thus reducing the unnecessary losses caused by these negative impacts on the farm.

Strengthen feeding management

Now the management of breeding pigs also advocates humanized management. Pigs are very intelligent animals. Only by providing pigs with the most comfortable growing environment, they are good at breeding pigs in order to fully realize their production potential and achieve the best feed conversion rate, thus making pigs The field achieves maximum economic benefits.

First of all, we must ensure a certain stocking density. If the density is too high, pigs will be easy to fight, and it is easy to spread the disease, especially respiratory diseases. If you maintain a reasonable density, the disease that is mainly transmitted through the mouth-to-mouth contact, such as the incidence of PRRSV, will be reduced. It will not pass through the air from one pig house to another, nor will it pass from a pig farm. Go to another farm. Therefore, maintaining a reasonable stocking density will effectively reduce the occurrence of some diseases, thereby improving the economic benefits of the farm.

Secondly, ventilation should be strengthened because the diseases in the fattening stage are mainly respiratory diseases, and their occurrence is closely related to the quality of air. The air quality is related to the concentration of dust, ammonia and other harmful gases. The dust can carry a large number of bacteria and viruses. If not ventilated in time, the dirty air is easily inhaled by the pig and is deposited in the lungs, causing the disease to occur.

Cooling is a key management measure during the hot summer months. There are many ways to cool down. Conditional pig farms can use water curtains to cool down. Unconditional pig farms can consider roof spray, outdoor shade nets, and some farms use spray, shower and other methods to improve pigs. The level of comfort and increased feed intake.

The quality of the feed is not good, or the design of the trough is unreasonable. The pigs are easy to arch out the feed and cause waste. Therefore, the unreasonable facilities of the farms are also likely to prevent pigs from eating reasonably and ultimately affecting economic benefits.

Ensure that the finishing pigs have enough water, especially on hot summer days, to reduce the stress response of the pigs. When the height of the drinker is not suitable, the blockage, the pressure of the water pipe is small, and the water flow rate is slow, it will affect the drinking water of the pig. In the feeding process of the pig, the water shortage is more serious than the stress of the lack of material.

Reasonable medication method

Drugs used in the fattening stage should comply with national laws and regulations, can not add illicit drugs, and must comply with the drug withdrawal period. Long-term medication and blind medication are neither safe nor economical. We must maximize the efficacy of the drug while complying with the medication rules.

After the pigs are transferred from the nursery to the fattening house, they can add one week of medicine in the feed. For example, add 80% of the original product to the feed, 125 grams, 15% of the chlortetracycline, or 10% of the doxycycline. In kilograms, it can effectively control sepsis caused by infection after transfusion or respiratory diseases of fattening pigs. This combination of drugs also prevents or even treats swine dysentery and colitis. Whether it is respiratory disease or colitis, it will cause the growth of fattening pigs to be slow and the feed conversion rate to decrease, resulting in uneven growth of finishing pigs, and the time of slaughtering is different. It is difficult to achieve full access and ultimately affect economic benefits.

For the breeding pigs in the fattening stage, the introduced customers should first let the breeding pigs drink water after long-distance transportation, and add electrolysis to the drinking water for three consecutive days to increase their resistance; add 80% of the original feed to the feed of 125 grams per ton of feed. 10% florfenicol 600g ~ 800g, for 7 days to 10 days, can reduce the incidence of respiratory diseases and colitis.
