How to keep the breed of three-yuan sow

This year, due to soaring pork prices, the price of pig seedlings is also on the rise. at present, the price of binary sow seedlings on the market is as high as more than 300 yuan, and many pig farmers are reluctant to give up and are afraid to buy pigs with problems. So in order to raise pigs to earn money, many pig farmers want to keep three yuan sows for breeding, how to do it specifically? Let's take a look.

1. Carefully selected and retained

Ternary sows have some disadvantages, such as unobvious affection, low success rate of mating, serious relapse, poor motherhood and so on, but the offspring have different qualities because they contain Duroc pedigree, grow fast and are easy to be obese. However, after years of practice, the young born to excellent sows can inherit certain high-quality genes, so when selecting sows for breeding, they must be careful and carefully selected from many aspects, requiring a handsome face, broad back and broad body, strong limbs, more than 6 pairs of effective nipples, quiet behavior and docile character.

2. Fine management

The health management of ternary sows is easy to be ignored, so in order to do a good job in the prevention and control of non-state classical swine fever, non-specific immunity drugs can be continuously added to the feed, and the wages of deworming and basic immunity must be completed twice before breeding. After 60 kg, the special feed for backup sows should be used, and the feed intake should be controlled after 80 kg to ensure that the temperature and humidity of the feeding environment are suitable. During the breeding period, the management of estrus should be strengthened, and pig stimulation, enhanced exercise, half-limit hurdle feeding, light stimulation and other methods can be used to stimulate estrus.

3. Accurate nutrition

In order to ensure the normal development of reproductive organs, intestines and limbs and hooves of ternary sows, and to ensure that they have enough physical strength, healthy intestines and solid skeleton when entering the breeding period. First of all, farmers should timely replace the reserve sow feed, while conditional nutrition, so as to ensure that ternary sows have adequate nutritional growth and development.

4. Precise improvement

The recurrent hybridization technique can be used in breeding, using ternary sows and purebred large white boars, and then crossing the offspring of suitable sows with Duroc, so that excellent commercial pigs can be produced. This method is suitable for most farmers. Breeding techniques can also be used to cross with Duroc to continuously reduce the proportion of Duroc's consanguinity, which can be used as a breed in the third generation. This method is suitable for pig farms with long-term breeding plans.
