I. Introduction.
Sow biting piglets is a common behavioral problem that brings a lot of trouble to the pig industry. In order to solve this problem, we need to understand why it happens and take measures to avoid it. This article will discuss how to avoid sows biting piglets**.
2. Cause analysis.
Nutritional deficiencies: The sow's nutritional needs are not met, especially minerals, vitamins and proteins, which can lead to abnormal behavior in the sow, including biting piglets.
Environmental factors: Poor breeding environment, such as high temperature, excessive humidity, poor ventilation, etc., may lead to irritability of sows, thus biting piglets.
Improper management: Adverse stress factors such as startling and overstimulation may cause anxiety and nervousness in sows, and then bite piglets.
Inexperienced sows: First-time sows may lack experience in caring for piglets, leading to piglet-biting behavior.
3. Preventive measures.
Provide adequate nutrition: Ensure that sows receive enough nutrients, especially minerals, vitamins and proteins, to meet their physiological needs.
Optimize the breeding environment: Maintain a suitable breeding environment, including temperature, humidity and ventilation, to reduce the adverse effects of the environment on sows.
Strengthen management: Avoid unnecessary stress to the sow, such as avoiding sudden noise or disturbances. At the same time, regularly check the health of the sow to ensure that it is in good physiological condition.
Increase sow-piglet interaction: In the prenatal and postpartum stages, increase the chance of sow-to-piglet contact, help sows become familiar with and accept piglets, and reduce the occurrence of biting behavior.
Training and observation: For sows farrowing for the first time, strengthen the observation and training of their behavior, so that they can gradually adapt to the work of farrowing and parenting.
Use of milk replacers: For piglets that cannot be fed by sows, artificial feeding with milk replacers can be considered to reduce the risk of sow bites.
IV. Conclusions. 
To avoid the problem of sow biting piglets, it is necessary to consider a variety of factors such as nutrition, environment, management and sow experience. By providing appropriate nutrition and breeding environment, strengthening management, and increasing the interaction between sows and piglets, the occurrence of sow biting behavior can be effectively reduced. At the same time, for sows farrowing for the first time, training and observation should be strengthened to help them adapt to farrowing and parenting. Through the comprehensive application of these measures, the efficiency and production performance of the pig industry can be improved.
