How old is the breeding pig to mate?

Pig breeding is one of the most common and important breeding projects in China, because the annual consumption of pork in our country is very large, ranking first in all meat products. When raising pigs, in order to ensure the normal reproduction and continuous breeding of pigs every year, the breeding work of pigs is very important. So how old does a breeder pig have to grow before it can mate? The following editor will give you a brief introduction, let's have a look!

1. The first mating age of boars

In the normal breeding environment, we have to determine the first mating age of boars according to the breed of pigs. For example, if it is a small, precocious variety, it should generally be carried out at the age of 8 months and when the weight is above 60kg. If it is a large late-maturing variety, then it should be mated in one year and the physique 90kg or so. At the time of first mating, the body weight of boars should be half or more than that of adult pigs. If the boar is too old but the weight is too small, it should be eliminated in time. If it is used for breeding, it will do great harm to the growth of piglets.

2. Sow mating age

The first mating age of sows should reach at least half a year, and the weight should not be less than 50kg. However, if it is an introduced variety, then the mating age remains the same, but the weight is best kept above 90kg. Therefore, for the introduced or cultivated varieties, even if the mating age is up to, but the weight does not reach the standard. Then it is necessary to improve the nutritional level and wait until the body weight reaches the standard before mating. However, if the body weight is reached, but the month age is not reached, then the feed should be properly restricted to avoid overweight, and breeding can be delayed until the third estrus of the sow.

3. Mating intensity

When breeding pigs, we must pay attention to control the intensity of breeding. For first-time young boars, the maximum number of mating times per week should not exceed 3 times. On the other hand, the age of 2-4 years old is the prime of boar, so when entering the peak breeding period, it can be mated once a day. If you need to breed twice, the interval between them should be kept at about 10 hours, and you should have at least one day off every year, and two days is the best. In a decentralized and non-seasonal environment, an adult boar can breed up to 25 sows, but if it is raised seasonally, it can only be bred with about 15.

4. Matters needing attention in breeding

When mating, we should pay attention to choosing a suitable mating time. If the breeding is done in summer, it should be avoided during the high temperature at noon. When mating in winter, it is necessary to avoid the low temperature in the morning and evening. The boar cannot be fed within an hour before and after mating, and the boar should not be exposed to cold water after mating. When mating, it is best to provide a special site for it to ensure that the ground is flat and convenient for the mating work. During the breeding time of boars, be careful not to cause any interference to boars, so as to avoid boars being frightened.
