Using B-ultrasound and several other

here are many ways to identify cow estrus, such as measuring the level of estrogen or other reproductive hormones in the cow's blood or milk, and using B-ultrasound detection methods to diagnose the estrus of cows based on the changing patterns of their sexual cycles. In herds of cattle, bulls with cut vas deferens or removed penises are used for estrus testing, or cows that particularly like to mount are used instead of bulls for estrus testing. It can be observed that the estrus cows are closely following the estrus cows. If the chest of the estrus cows is painted with color or a marking device with paint is installed, all estrus cows that have been mounted will leave marks on their hips. However, hormone testing The force method is difficult to promote in production because it requires sampling and laboratory operation, and the individual variation of reproductive hormone secretion of cows is large; although the test cows have certain practicality when they are raised in large groups, they are not applicable when they are raised in intensive large groups or small-scale breeding, and there is a possibility of spreading diseases through the test cows, so most of them are not adopted. The main force method for identifying cow estrus in production practice is based on the changes in the behavior of cattle and the changes in reproductive organs. The main techniques are external observation, vaginal examination, rectal examination, and cattle B-ultrasound.

B-ultrasound for cattle

The method of using B-ultrasound ultrasound to identify the estrus of cattle is a relatively accurate method when used in the pasture. At that time, due to various constraints, this method has not been pOPUlarized in the cattle farm.

Comparing the above methods for identifying estrus of cows, external observation, vaginal examination, rectal examination, and cattle B-ultrasound. In the usual feeding and management of cows, it is the best choice to use these methods together. Of course, if the conditions of the cattle farm permit, the cattle B-ultrasound method is more accurate than other methods.
