CATDOLL : An effective strategy to solve the problem of new sows not getting pregnant for one year

Sows are an extremely important part of the breeding industry. Especially today when the demand for pork is gradually increasing, the improvement of breeding efficiency is particularly urgent. However, some farmers may face the problem of sows not getting pregnant, which not only affects economic benefits, but may also cause trouble to the overall breeding management. This article will explore the possible reasons why new sows do not get pregnant for a year and provide corresponding solutions.

Common reasons why new sows do not get pregnant

Understanding why your sow is not getting pregnant is the first step in diagnosing the problem and implementing an effective solution. Here are some common reasons:

• Malnutrition : Sows need adequate nutrition before pregnancy. If the protein, vitamins and minerals in the feed are insufficient, it may lead to a decrease in the sow's reproductive ability.
• Environmental stress : A high temperature, humid or overly cold environment will affect the physiological state of the sow and even cause hormone secretion disorders, thus affecting conception.
• Disease impact : If sows are infected with certain diseases, such as reproductive and respiratory syndrome virus (PRRS), swine flu, etc., their fertility may be affected.
• Improper breeding techniques : If scientific methods are not followed during breeding, such as choosing the wrong time for breeding, sows may not be able to conceive successfully.
• Genetic factors : Some sows may have lower fertility due to genetic problems. In such cases, it may be necessary to replace the breeding sows to improve overall reproductive performance.

Strategies to improve pregnancy rate of new sows

In response to the above problems, farmers need to adopt a series of effective strategies to improve the pregnancy rate of newly raised sows.

1. Improve nutritional management

Reasonable feed combination is crucial to the fertility of sows. It is necessary to ensure that the sow's diet contains sufficient protein, energy and trace elements. Recommendations:

• Carry out regular feed analysis to ensure that the feed composition meets the sow's needs.
• Choose a high-quality, nutritionally complete feed and consider adding mineral and vitamin supplements.

2. Optimize the breeding environment

The production environment of sows also directly affects their fertility. Farmers should pay attention to the following aspects:

• Keep the pig house clean and sanitary and disinfect it regularly to reduce the spread of disease.
• Provide suitable temperature and humidity to ensure sows grow in a comfortable environment.
• In hot seasons, proper ventilation and cooling should be implemented to prevent sows from being affected by environmental stress and affecting conception.

3. Strengthen disease prevention and control

Disease is another major factor affecting sow productivity. To this end, farmers should:

• Get regular health checks to diagnose and treat illnesses promptly.
• Vaccinations should be done on time to reduce the chances of disease.

4. Improve breeding technology

Breeding is an important step that directly affects sow conception. Farmers should:

• Understand the estrus cycle of sows and choose the best time for breeding.
• Determine a reasonable breeding method, common ones include natural mating and artificial insemination.
• Ensure the quality of breeding pigs, strengthen the management of breeding pigs, and select healthy and well-formed breeding pigs for breeding.

5. Modification of genetic resources

If a sow does not get pregnant for a long time, but other factors are checked out correctly, it may be necessary to consider replacing the sow. Good genetic characteristics of sows are critical to improving reproductive efficiency. Selecting sows with a good reproductive record can effectively improve the production performance of the entire farm.

Summarize

Faced with the problem that newly raised sows have not become pregnant for a year, farmers need to conduct a thorough inspection from many aspects to find out the root cause of the problem. Through reasonable nutrition management, optimizing the breeding environment, strengthening disease prevention and control, improving breeding technology and changing genetic resources, the pregnancy rate of sows can be effectively improved, thereby improving breeding benefits.

Thank you for reading this article. I hope the above measures can help you improve the pregnancy rate of sows and optimize breeding management. Through this article, you can get practical suggestions to help you better solve the problems encountered in breeding.
