First, look at milk identification
The milk that is squeezed out by hand is honey-colored, paste-like and non-flowing. Most of them are pregnant cows. If it is white, and if it is squeezed out naturally, it will be an empty cow.
Second, look at breast recognition
The breasts are swollen, the nipples are hard and straight, and are pregnant cows. The breasts do not swell and the teats are not hard and straight.
Third, look at the bull's eye
Immediately above the pupil of the pregnant cow's pupil, three particularly prominent upright blood vessels appear on the iris, the so-called pregnancy vessels, which fill up the surface of the iris and appear purple. The blood vessels on the iris of pregnant cows did not appear to be small.
Fourth, to see oral recognition
Open the mouth of the cow and look at the sublingual meat on both sides of the mouth. If it is bright red, it is a pregnant cow. If it is pink or light red, the cow is not pregnant.
Fifth, using pressure abdominal recognition
The person stands on the left side of the cow facing the rear, with his left hand assisting the cow's back and the right hand gently pressing on the left intestine. If something touches and hits the hand, or if something touches the belly, the cow is pregnant. .
Sixth, using alcohol test
Take 100 milliliters of fresh milk from the cows to be tested and place them in sterile glassware. Add 1 milliliter of medical alcohol, 1 milliliter, into fresh milk. Mix thoroughly. If condensation occurs within 5 minutes, prove that The cow is already pregnant and if she does not gather until half an hour later, she is not pregnant.
Seven, see tail identification
When the cow's tail does not sway, if the cow is covered and left or right tilted, the cow is pregnant. If the tail is covering the middle vertically, it means there is no pregnancy.
