Introduction to Yanggu Black Pig

Yanggu Black Pig is a specialty of Yanggu County, Liaocheng City, Shandong Province. Yanggu Black Pig has obtained the National Geographical Indication Certification Trademark. Yanggu County is located in the western part of Shandong Province, at the southern end of Liaocheng City, north of the Yellow River, east of the Grand Canal, and south of Henan Province. The black pigs produced in Yanggu County have oily black fur, delicate body shape, sensitive response, strong disease resistance and reproductive ability, and are cold resistant. Black pigs are known as "grass fat pigs" and have excellent fattening performance. Adult boars typically weigh around 117 kilograms, while adult sows typically weigh around 95 kilograms. Under standard feeding conditions, the live weight at 240 days of age can reach about 92 kilograms, with an average daily weight gain of 509g during the fattening period and a lean meat percentage of about 46%. The feeding of black pigs should have diverse and reasonable feed to ensure comprehensive nutrition. Only by reasonable combination of green feed, coarse feed, and refined feed can pigs meet their various nutritional needs. Pay attention to the relationship between dietary volume and pig feed intake. The volume size of feed can be measured by the dry matter content of the feed. Based on the daily requirement of 2.5-4.5 kilograms of dry matter per 100 kilograms of body weight for pigs, the dry matter ratio of green feed, roughage, and concentrate feed should be 5:3:2. In terms of green feed, black pig farming should choose grass seeds that are fresh, tender, have multiple leaves, high protein content, and have good palatability. Grass should be dried before feeding. Pigs are usually fed 2-3 times a day. Male (female) pigs and fattening pigs can be fed twice a day, while piglets and growing pigs can be fed three times a day. The feeding schedule should avoid the hottest weather at noon and the most frequent periods of personnel activity. After 60 days of age, black pigs should be raised in separate pens, with 2-3 pigs per pen, to prevent them from playing and running outdoors and consuming energy. During the empty pregnancy stage and the first 80 days of pregnancy, sows can mainly use green feed, high-quality roughage, and dregs feed, with only about 1 kilogram of concentrate per day. Feed 2-3 kilograms of concentrated feed per day for the first month before delivery. In this way, it ensures the normal development of the fetus and every pregnancy of the sow. It can also save 60-90 kilograms of concentrated feed. At 30 days of age, young boars and 40 days of age, young sows were castrated, resulting in an increase of about 15% in weight compared to the commonly used 60 day age castration, and the wounds healed faster. Weaning piglets from 60 days of age to 40-45 days earlier can promote early estrus and mating of sows, shorten the empty period, and relatively save feed.

Black pig farming also requires timely disinfection, good cage hygiene, and daily cleaning and removal of feces and dirt; Thoroughly disinfect the cage once a day with disinfectant. To ensure proper immunization, follow the hygiene and epidemic prevention procedures for pigs to receive triple vaccine injections, and timely deworming, gastric lavage, and gastric health maintenance. After 60 days, the second dose should be administered. At the same time, attention should be paid to the humidity and temperature management of pigs. The suitable temperature for pigs is 15-25 ℃, and the relative humidity is 55% -60%. If the temperature and humidity are too high, it is easy to cause heatstroke and metabolic disorders. Therefore, when the summer temperature exceeds 28 ℃, the cage should be rinsed with water at noon, and a shed should be set up to provide shade; If the temperature and humidity are too low, the pig's body will dissipate more heat and consume more feed, which will increase the feeding cost. Therefore, in winter, it is necessary to do a good job of keeping warm and keeping warm. A 10-15cm thick layer of hay should be laid in the cage, and warm water should be used to mix the feed.
