New sows can be mated at 7 months! There are many varieties of sows in China, different breeds of sows can be mated at different ages, too early or too late to breed is not conducive to sow farrowing, generally speaking, an average of 7 months can be mated, the average weight of mating should be more than 70kg, too thin pigs can not be mated, such as China's breeding pig breeds in 6-8 months weighing 80-100kg can be mated, Yorkshire (foreign pig breeds) in 8-10 months of age, weighing more than 100kg can be mated, Yorkshire, Duroc, Hampshire and other large sows should weigh more than 120kg before they can be mated, the specific time of the first breeding is best to choose the third estrus time, the first puberty period, the second estrus period do not breed sows, because too early mating has many evil fruits, easy to stillbirth, less calves, piglets are not healthy, not conducive to breeding. <>

Anonymous users2024-02-06Boars are larger than sows, in general, under the same breed and the same age, adult boars will weigh much more than sows, of course, different breeds of pigs have different weights, taking Landrace pigs as an example, adult sows weigh more than 200-350 kg, and adult boars weigh 300-500 kg.
Difference Between Boar and Sow:
Weight. Boars weigh differently from sows, adult boars of the same breed generally weigh more than sows, about twice as much as their weight, and adult sows of the same breed weigh less than boars, weighing nearly half.
Use. Boars are used differently from sows, as domestic animals can be raised for food or as breeding pigs, to cultivate new breeds, and sows can be used as domestic animals to raise or breed pigs.
The meat bucket is repetitive. The meat of the female pork is very loose, mainly due to its sexual laziness, the boar is more active than the sow, so the meat of the male pork looks particularly firm. After stir-frying, the water in the female pork volatilizes very quickly, so its taste is particularly chai.

Anonymous users2024-02-05The first suitable age for breeding of new sows is: the breeding breed is generally 8 to 10 months old and weighs about 100 kg; Sows of the local breed are 6 to 8 months old and weigh 70 to 90 kg.
The first puberty of sows is generally 5 to 8 months old, with an average age of 7 months. In some parts of the country, varieties can be as early as 3 months of age. Sows are basically fertile when they reach first puberty, but at this time the sows are not yet mature and weigh less, about 60% to 70% of their adult weight.
If breeding, the burden on the sow is heavier, the litter is small, and the number of births is low, which affects the reproductive performance of the sow in the future.

The pork we eat can be female pork. Pork is not divided into male and female, but is selected and slaughtered according to factors such as the age and weight of the pig. In the market, pork can be roughly divided into two categories: boars and sows, but it does not mean that only boar meat can be eaten, and female pork can also be eaten. >>>More
