Cow pregnant hand touch method, how can you see it? How many months will the breasts get bigger?

It can be observed about one month after mating of the cow, if the cow is pregnant, there are three obvious blood vessels directly above the pupil, which will be congested, and then highlight the surface of the iris, which is purplish red, or open the cow's mouth and look at the caruncle on both sides of the tongue. If the color is bright red, it means that the cow is pregnant. In general, the breasts and nipples of first-born cows can be seen gradually enlarged after 3-4 months of pregnancy.

I. the method of identifying the pregnancy of cows

1. Look at the eyeball

The general eyeball determination method is relatively accurate, and it can be observed about a month after the cow is bred. If the cow is pregnant, there are three obvious blood vessels directly above the pupil, which are small and not exposed at ordinary times. If pregnant, it will be congested, and then highlight the surface of the iris, which is fuchsia and easy to identify.

2. Look at behavior

When cows are in estrus, they are often excited and restless, and they will moo loudly, resulting in loss of appetite, and some cows will keep circling around the enclosure with a grumpy temper, and the duration of estrus varies, and after breeding after estrus, there will be no oestrus behavior, temperament will also become more docile, appetite will increase, hair will be shiny, generally judged to be pregnant, there will be an increase in food intake and fast fattening speed. And the increase of rest time.

3. Look at the mouth

Like looking at the eyeball, looking at the mouth is a more accurate way to judge, you can open the cow's mouth, and then look at the caruncle on both sides of the tongue. If the color is bright red, it means the cow is pregnant. If it is light red or pink, it means she is not pregnant yet.

4. Look at the tail

The tail of a cow is usually vertical. If it is a pregnant cow, its tail is slightly sideways, not natural vertical. This method is relatively simple and easy, and only requires careful observation. The accuracy is still very high.

5. B-mode ultrasound

If there is a conditional farm, you can configure a veterinary B-ultrasound machine, which can accurately determine whether the cow is pregnant or not one and a half months after mating, and carefully observe the growth state of the fetus, and then make corresponding measures.

Second, cows get bigger breasts after a few months of pregnancy.

1, the performance of the cow after pregnancy, from the appearance, the cow is no longer in estrus, the temperament becomes docile, the food increases, the fat fur is bright, and as the fetus grows up, the volume of the uterus increases and squeezes the viscera to the right ventral side, which makes the external breathing of the cow become shallower and faster, resulting in an increase in the number of urination and defecation.

2, the general first birth of the cow, after 3-4 months of pregnancy, you can see the breast and nipple gradually enlarged, to 7-8 months later, the swelling is more obvious, and then will secrete colostrum, the late pregnancy breast will swell, the nipple will also harden.
