The estrus test of rams should be carried out every morning. The estrus ram uses its nose to sniff the ewe, or teases the ewe with its hoof, or even climbs on the ewe's back. The ewe does not move, run, or refuse, or stretches its hind legs to urinate. Such estrus sheep are estrus sheep. The estrus sheep should be immediately painted with dye after the sheep B-ultrasound examination. It is not enough to have only one shepherd in each group during the estrus test, and temporary workers should be added. The estrus test site can be in the playground, on the grass slope, or in the sheep house, but it must be of appropriate size. If the playground is too large, the sheep will run around when chasing the estrus sheep, which is inconvenient to observe, and it is not easy to catch the estrus sheep. If the estrus test site is too narrow, the sheep are crowded, and the estrus ewes squeezed in the center are not easy to be found, and the purpose of completely selecting estrus sheep cannot be achieved. It is not convenient to catch estrus ewes on the grass slope. When testing estrus in the sheep house, the light should be bright. In some areas, estrus pens are set up, and small groups are tested in batches, which has a better effect. The sheep that are mated for the first time seem to be afraid of the ram. After being chased by the test sheep, they are not as easy to approach as the adult estrus ewes. They may stand to let the test sheep approach or the test sheep follow closely. Such ewes should also be selected as estrus sheep, and then judged by sheep B-ultrasound examination.

The ratio of test sheep should be 2-3 per 100 ewes. If there is manpower, the test sheep can be put into the flock at one time, and the estrus sheep can be quickly selected, or they can be put in batches. Because the sexual desire of the test sheep put in first has decreased after a period of trial, and they are not active in looking for estrus ewes, new test sheep will be replaced to find them in the flock. The herders should walk in the flock, drive away the lying and crowded sheep, let the test sheep get close to the ewes, and don't miss the estrus sheep. In some places, the test of estrus in a small group and the retest in a large group are better. Of course, it is best to use sheep B-ultrasound to combine them. During the mating season, each estrus test lasts about 1 hour. It is best to test once in the morning and once in the evening. Some people only test once in the morning. The key is to test estrus early, thoroughly and well every day, and strive to achieve both fattening and estrus testing under the monitoring of sheep B-ultrasound.
