Heat detection is the process of identifying which females are receptive to mating. A sexually mature female pig in good health should cycle every 3 weeks if she is not pregnant or lactating. (The estrous cycle of swine lasts approximately 21 days.) Heat Detection Heat detection is the process of identifying which females are receptive to mating. A sexually mature female pig in good health should cycle every 3 weeks if she is not pregnant or lactating. (The estrous cycle of swine lasts approximately 21 days.) Detection of estrus or standing heat is one of the most critical components of a successful swine breeding program. The widespread adoption of artificial insemination (AI) in the swine industry has shifted the responsibility of detecting estrus from boar to breeding technician.Accurate heat detection is essential for the correct timing of insemination. However, heat is often missed or misdiagnosed because the signs are overlooked. Follow the management guidelines below to ensure good timing, successful insemination and improved reproductive performance.

What is heat detection?
“Heat detection” is the common name for the identification of behavioural signs preceding ovulation in the cow (release of an ovocyte at a more or less regular interval in the region of 21 days but which may fluctuate depending on the animal, its breed, its parity and its physiological condition) with a view to …
How is heat detected in sows?
Vulvas of pigs nearing heat may be swollen, red, and discharge mucus. Applying pressure to the back of the animal to see if she will stand rigidly is the most common manner to check for standing heat. Often the female’s ears will be in an erect position during standing heat. Her tail may also move to expose her vulva.

What is estrus detection in pigs?
Estrus or Heat Detection Detection of estrus or standing heat is one of the most critical components of a successful swine breeding program. The widespread adoption of artificial insemination (AI) in the swine industry has shifted the responsibility of detecting estrus from boar to breeding technician.
What makes a good heat detection boar?
A good and manageable heat detection boar will provide touch by rooting, sound by barking and smell by emitting pheromones. In the environment of heat detection in preparation for artificial insemination in stalls, the stockperson must emulate the actions of the boar while the boar provides fenceline nose-to-nose presence of sight, smell and sound.
Why is accurate heat detection important for insemination?
Accurate heat detection is essential for the correct timing of insemination, however, heat (oesturs) is often missed or misdiagnosed because the signs are overlooked. Follow the management guidelines below to ensure good timing, successful insemination and improved reproductive performance.
