Sow not estrus may be a common problem in breeding, and its best method needs to consider a variety of factors. Here are some possible methods:
Adjust feeding management: The environment in which sows are kept and managed may affect their estrus performance. Make sure that the sow is kept in a clean and comfortable environment, with adequate drinking water and suitable feed. Clean the barn regularly to avoid excessive stress or high density.
Nutritional balance: The nutritional status of the sow has an important impact on its estrus status. Ensure that sows receive adequate nutrition, especially protein, vitamins and minerals. A veterinarian or nutritionist can be consulted to adjust the feed formula to meet the nutritional needs of the sow.
Good disease control: Disease and vaccination status can affect the physiology of the sow and thus its heat. Ensure that the sows are vaccinated with the necessary vaccinations and that regular disease detection and control are carried out.
Change in rearing environment: If the sow has been in the same rearing environment for a long time without estrus, consider moving it to a new environment or separating it from other pigs for a period of time to stimulate its physiological state.
Hormones**: In some cases, veterinarians may recommend the use of hormones** to induce sow heat. This needs to be done under the guidance of a veterinarian and the dosage and frequency of medication should be strictly controlled to avoid adverse effects on the health of the sows.
It should be emphasized that the best method for sows not to come into heat is best carried out under the guidance of a veterinarian. According to the specific situation, the veterinarian will conduct a comprehensive assessment according to the health status of the sow, the feeding environment and physiological characteristics and other factors, and formulate the corresponding plan.
