METHODS OF RAISING LIVESTOCK

Abstract

The invention relates to a method of livestock breeding. Specifically, the invention relates to methods for detecting estrus in sows in which the process of fertilization is carried out once estrus has been identified. In the first method, images of the rear end of each sow are analyzed to determine from signs related to the shape, size and / or color of the vulva whether the sow is in estrus. The analysis may utilize a program in which a large number of images showing the vulva of many sows known to be in estrus and known not to be in estrus have been previously analyzed to generate data on the previous images to establish a program to generate signals using the data to make decisions. In the second method, boars are confined and brought into close contact with sows, where images and / or sounds of each sow are analyzed to determine whether the sow is in estrus.
