Breeding Technology of Pitland Pig

The Petland pig is backcrossed by the French Bayer hybrid pig and the British Barkshire pig, and then crossbred with the British large white pig, which is mainly characterized by high lean meat rate, rear drive and plump shoulder muscle. the coat is grayish white with irregular dark black spots and occasionally a small amount of brown hair. let's take a look at the breeding techniques of Petland pigs.

Production performance of Petland Pig

1. Fattening performance: Pitland pigs grow rapidly under better feeding conditions, with a body weight of 90 kilograms at the age of 6 months, a daily gain of about 750 grams, a compound feed consumption of 2.5 kilograms per kilogram, a slaughtering rate of 76 percent, and a lean meat percentage of up to 70 percent.

2. Reproductive performance: once the boar reaches sexual maturity, it will have a strong libido. Semen collection and training will generally be successful. The ejaculation volume is 250,300 milliliters and the sperm count is up to 300 million per milliliter. The motherhood of sows is not inferior to that of local breeds in China, and the breeding rate of piglets is 9298%. The proestrus of sows is generally 190 days old, the estrous cycle is 18-21 days, the number of pups per birth is about 10, and the number of live pups is about 9.

Prevention of dystocia in Petland Pig

The main results are as follows: 1. To prolong the age of mating months, the proestrus of Pitland pigs is generally 8 months old, and the apparent weight of mating months should be 11 ~ 12 months old.

2. Exercise should be strengthened in the middle and later stages of pregnancy and the nutritional concentration should not be too high.

3. Use prostaglandins to give birth 1-2 days ahead of schedule. It is best to control the birth during the day to facilitate midwifery (usually one dose is injected in the morning, and the next morning begins to give birth).

4. When dystocia occurs, midwifery should be carried out, midwifery should not be too urgent, and the birth canal should not be damaged. Arms and midwifery instruments must be thoroughly disinfected, minimize the number of arms entering the birth canal, rinse the uterus within 7 days after delivery, eliminate inflammation, and prevent the next estrus or mating difficulties.

5. When keeping the seed, try not to keep those pigs with too large hindquarters and smaller vulva as backup sows.

Stress attention of Pittland Pig

1. When boars take part in mating, they should have appropriate exercise time.

2, when the pig turnover, as far as possible the original pen the original nest, the pigsty should be firm to prevent the phenomenon of fighting.

3. When pigs move around, they should be gently coaxed and driven slowly, and should not be driven by force or strenuous exercise.

4. It is best for sows to give birth on the ground, and then go to bed to raise them.

5. In hot summer, boars and sows, especially litter sows, should be equipped with cooling facilities, such as electric fans, and air conditioners can be installed if possible.

6. In the process of transportation, overcrowding, overheating or poor ventilation should be prevented. Do not be forcibly tied up when getting on and off the bus. A sedative can be injected before transportation.

7. If you find stress, you should stop its stimulation immediately, keep quiet, pour cold water on its neck, water slowly, not all over the body suddenly, and do not inject sedatives when stress occurs.
