Increasing the annual productivity of sows is one of the important goals pursued by the farming industry, and here are some possible ways to do it:
1.Maintain the proper structure of the sow herd: The fecundity of the sow has an important relationship with age and parity. First-time sows are still in the growth and development stage, and the reproductive ability is low, and the number of litters is usually small. With the increase of age, the development of sows gradually matures, and the fecundity improves, generally at the time of 3 6 parities, the fecundity is the strongest, and the number of live piglets is also more. Therefore, when raising sows, it is necessary to maintain a reasonable structure of the sow herd, and keep the sows in the herd at 3 6 parities as much as possible while keeping the sows in a stable and high-yield state. At the same time, it is necessary to eliminate sows with excessive parity and poor reproductive ability in time and supplement gilts to maintain a reasonable parity structure of the sow herd.
2.Ensure adequate nutrition: Sows need to consume enough nutrients such as proteins, carbohydrates, fats, and vitamins to maintain good health and normal reproductive capacity. Therefore, sows should be provided with a comprehensive and balanced feed to meet their needs at all stages of growth and production.
3.Maintain a good environment and hygiene: The breeding environment of sows should be kept clean and tidy, with appropriate temperature and humidity, and the pig house and environment should be disinfected regularly to prevent environmental pollution or disease infection. A good environment can improve the comfort of the sow, which is conducive to maintaining her health and improving reproductive efficiency.
4.Proper breeding management: The selection of healthy boars, the appropriate number and time of breeding, appropriate methods and techniques will all have an impact on the reproductive rate of sows. Therefore, it is necessary to make a good breeding plan, choose the right boar for breeding, grasp the timing of breeding, and improve the success rate of breeding.
5.Do a good job in pregnancy management: In the perinatal period of sows, it is necessary to develop health care plans, nutritional adjustments, disease (reproductive system, digestive system, etc.) prevention and other aspects of management to ensure the health of sows and fetuses to the greatest extent. The quality of pregnancy management directly affects the litter size of the sow and the survival rate of the piglets.
6.Disease prevention and prevention: timely detection and prevention of sow diseases (such as triadosis, etc.) to avoid affecting reproductive ability and production performance. Sows need to be inspected regularly, and if any abnormalities are found, they need to be dealt with in a timely manner.
To sum up, improving the annual productivity of sows needs to start from many aspects, including maintaining a reasonable sow herd structure, ensuring adequate nutrition, maintaining a good environment and hygiene, reasonable breeding management, good pregnancy management, and disease prevention and so on. Only by taking these factors into account and taking effective measures can the annual productivity of sows be effectively improved.
