CATDOLL : CATDOLL: Treatment of delayed labor caused by abnormal piglet fetal position

Reasons why piglets do not enter the birth canal

Piglet failure to enter the birth canal is a relatively common phenomenon in pig herds and may be caused by the following reasons:

• Abnormal fetal position: The abnormal fetal position of piglets in the sow's uterus is one of the main reasons why they cannot enter the birth canal. Common abnormal fetal positions include cervical hyperextension, back and waist flexion, and hip and limb extension.
• Abnormal fetal development: Abnormal piglet embryo development can also cause it to be unable to enter the birth canal. For example, if the fetus is too large or has malformed development, it will cause the labor process to be prolonged.
• Sows are timid: Some sows become fearful during the birthing process due to the environment, noise or emotions, which leads to their refusal to enter the birth canal.

Treatment

When it is found that the piglets cannot enter the birth canal, the farm staff should take the following measures in time:

• Check the fetal position: First, confirm whether the piglet's fetal position is abnormal. For piglets with abnormal fetal position, they should be corrected immediately. You can help the piglet enter the birth canal by gently massaging the fetus and appropriately changing the sow's body position.
• Observe the behavior of the sow: The piglet's failure to enter the birth canal may be related to the sow's behavior. If the sow is observed to be timid or nervous, measures should be taken to eliminate its fear, such as improving the pig house environment and reducing noise.
• Seek veterinary help: If the piglet's fetal position is complicated or the piglet cannot enter the birth canal due to abnormal fetal development, it is recommended to seek veterinary help. The veterinarian can remove the fetus or perform surgical correction according to the specific situation.

Precautions

In order to reduce the incidence of piglets not entering the birth canal, farms can take the following preventive measures:

• Reasonable breeding: Selecting healthy and excellent pig breeds for reasonable breeding is an important measure to prevent abnormal fetal position. Reasonable breeding can reduce the probability of fertilized egg deformity and abnormal embryo development.
• Scientific feeding: Providing a reasonable feeding environment and feed, strengthening the nutritional management of sows, and enhancing the physical fitness of sows will help reduce the occurrence of abnormal piglet fetal positions.
• Standardize labor management: Strengthen the training of farm staff, improve their ability to observe the sow's farrowing process, detect abnormal situations in time and take corresponding measures.

In short, abnormal fetal position or abnormal fetal development of piglets may cause them to not enter the birth canal. When this happens, farm staff should take timely treatment measures, including correcting the fetal position and eliminating the sow's fear. In addition, preventive measures are also important, including reasonable breeding, scientific feeding and standardized labor management. By taking these measures, the occurrence of piglets not entering the birth canal can be effectively reduced and the breeding efficiency can be improved.
