CATDOLL : CATDOLL: How do sows test estrus - How to understand the methods and significance of sows' estrus testing behavior

Importance of sow estrus testing

The estrus test behavior of sows is an important way of communication. It not only promotes mating in the pig herd, but also helps farmers or breeders determine the pregnancy status of sows. By observing the estrus test behavior of sows, people can judge whether the sows are in estrus, thus providing an important basis for the breeding management of the pig herd.

Characteristics of sows’ estrus testing behavior

During estrus, sows will display a range of estrus behaviours, including:

• Poised to jump: The sow will suddenly jump and arch her back to attract surrounding boars.
• Squeak or hum: Sows make high-frequency squeaks or hums to attract boars.
• Pig genital area congestion: The sow's external genitalia will become congested and swollen to increase the interest of the boar.
• Chasing and jumping: Sows will chase boars around or jump to show their excitement.
• Tail lift: Sows will lift their tails and keep them horizontal to signal to the boar.

Methods for observing sows' estrus

In order to observe and record the estrus behavior of sows, the following methods can be used:

• Install cameras: Install cameras in the sow pens for real-time monitoring and recording for later observation.
• Record observation time: Observe the estrus behavior of sows in the pen regularly in the morning and evening every day.
• Observation index record: Pay attention to the sow's jumping, screaming, external genital congestion, number of chasing and jumping, etc., and record them.

The relationship between estrus testing behavior and sow conception

The estrus behavior of sows is one of the important bases for judging whether they are pregnant. If the sow continues to show estrus behavior for a period of time after mating, it means that it may not be pregnant. If the sow stops estrus behavior shortly after mating, it is very likely that it is pregnant.

Conclusion

By observing the estrus test behavior of sows, we can not only understand the estrus status of sows, but also provide a reference for the reproductive management of pigs. Correctly understanding the importance of sow estrus test behavior, adopting appropriate observation methods, and combining other reproductive management techniques can improve the reproductive efficiency of pigs and bring greater economic benefits to the breeding industry.
