How many nipples does a pig have?

It varies with varieties, generally between 8- 16.

For example, there are 5 pairs of nipples in Xiang pig, and a few 6 pairs.

The nipple number of Xinjiang white pigs is genetically stable, and the nipple table values are all above 14.

The nipple number frequency of 14 and 15 strains of Xinjiang black pig is above 65%. The frequency of 14 nipple is mostly above 85%.

The peak nipple number of Xinrong I line is 14, and the average large colony number is 13.59 1.46, which is 0.95 more than Rongchang pig.

Extended data

Health problems of sow nipples;

First, congenital problems.

Congenital problems of sow nipples are rare, because most pig farms are cautious in seed selection. After all, the cost of raising a sow is not small. If you choose a sow with developmental problems or physical defects, all the costs will be wasted.

1, we also talked about what a healthy nipple is before nipple dysplasia. The specific criteria are: the slender nipple type is the best, which is one of the concentrated manifestations of the perfect breast development of sows, followed by the round type (probably the unsatisfactory breast development). However, if the nipples of sows are completely undeveloped or necrotic, it is likely to lead to the loss of lactation ability of sows.

2. Internal problems of breasts

In another case, the problem of sow's breast development can't be seen from the outside, but there is a fault inside. For example, the obstruction of mammary duct or sphincter inversion in sows will seriously affect the lactation ability of sows.

Second, the day after tomorrow.

The acquired problems of sow nipples are mainly caused by trauma.

The sow's nipple was scratched by a sharp weapon. To put it bluntly, it is the problem of feeding environment, whether there are sharp objects in the pigsty, whether the ground is too rough and so on. We must pay attention to these details, because the nipples of sows are very fragile, and it is easy for them to directly rub against foreign objects in their sleeping position.
