The original seed has more than 3,000 Wulian black pig
Wulian Black Pig is a local fine pig breed in Wulian County, and its breeding volume has dominated the local area. In 1990, Wulian Black Pig won the first place in Shandong Province's Golden Pig Award. Since 1998, especially in the 21st century, Wulian black pigs have been violently impacted by “foreign white pigs†and were once endangered. In order to protect this excellent local variety, the Municipal Animal Husbandry Department decided to protect and breed Wulian Black Pig, and established Rizhao Local Black Pig Breeding Co., Ltd. with Rizhao Port Property Co., Ltd. Ecological Farm. The 83 Wulian black pigs that have returned to Wulian’s “rescue†have been developed through the base and have grown to more than 3,000 heads.
History Shandong "Golden Pig Award" first place
On November 21st, the reporter went to the newspaper Zizigou Village, Nanhu Town, Donggang District. The village is located in the local black pig breeding base in Rizhao City, where Wulian Black Pig settled. The base manager Ma Rufeng took the reporter to visit the exhibition hall and talked about the ups and downs of Wulian black pig.
In the 1940s, Wulian Black Pig has become a traditional fine pig breed in the region. Since 1975, Wulian Black Pig has carried out planned breeding. By 1983, a physique structure was basically formed for mountain grazing and feeding, resistance to rough feeding, strong disease resistance, fast growth, high birth weight, and lean meat. The high-rate, well-loved pig breed, Wulian Black Pig Breeding Project won the first prize of Weifang City Scientific Research. Wulian Black Pig is also listed as one of the four female pigs in Shandong Province. In 1990, Wulian Black Pig won the first place in Shandong Province's Golden Pig Award.
Since 1998, Wulian black pigs have been hit by the Yang Sanyuan pigs, and the amount of breeding has decreased year by year. According to the statistics of Wulian Black Pig at the end of 2005, there were only 27 males and 276 females and sows. At this time, the white pigs entered China in large numbers. Among them, the “Du Chang pigâ€, which is a hybrid of Duroc, Changbai, and Kexi pigs, is customarily called “Yang Sanyuanâ€. Yangbai pigs quickly dominated because of their fast growth and easy feeding.
Grab the two months of "grab" back to 83 black pigs
Seeing that the once fine black pigs were on the verge of extinction, the livestock department began to protect. From March to April 2009, Ma Rufeng and the director of the Production Bureau of the Municipal Animal Husbandry Bureau Su Xunzhi and the head of the animal husbandry station Wang Haizhou began a arduous survey. "For two months, we ran through 10 towns and towns such as Hong Ning, Gao Ze, Xu Meng, Hubu, Street, Eunuch, Songbai, Chaohe, etc. in Wulian County. As long as I heard where there is, we I immediately drove.†Ma Rufeng said that the results of the census are very pessimistic. The number of Wulian black pigs is very small, and some have lost their original characteristics because of hybridization. Among the 118 households with 208 heads of Wulian black pigs (13 boars), there were 83 heads (including 6 boars) that met the Wulian black pig breed standard. The 83 Wulian black pigs became the core group of Wulian black pigs, and were divided into 6 strains according to their bloodlines to carry out breeding work.
Breeding genetic technology to purify black pig
The reporter went to his original seed field to find out. The management here is very strict. The door must be disinfected first, and the white coat and shoe cover are put on. The workers are spraying lime water on the road to disinfect. Rows of neat pig houses, the health conditions inside are also better, clean the pig house every day. “The pigs here have basically been automated, and there are switches for drinking and eating. When the pigs are hungry, they will touch the switch and avoid the waste of food.†Ma Rufeng said.
"From the initial 83 Wulian black pigs, it has now grown to more than 3,000 heads, including more than 200 sows." Ma Rufeng told reporters that the breeding of black pigs is very complicated. Breeding performance, production performance, physical appearance, and meat quality were measured at different ages, including birth, 21 days of age, weaning age, 2 months, 6 months, 100 kg, and breeding. For genetic testing, blood samples should be taken separately and sent to the Provincial Academy of Agricultural Sciences. At present, the births are already the second generation, and the third generation is also undergoing breeding, and the most obvious features are selected. Ma Rufeng pointed to a pig and said, "The characteristics of this pig are very obvious, and the head has a distinct diamond pattern, which is a typical characteristic of Wulian black pig."
Feeding resistant to roughage, long growth cycle
“Wu Lian black pig was defeated by Yangbai pig because it has a long growth cycle. Farmers are pursuing economic benefits, so they have changed their Yangbai pigs. In fact, the long growth cycle and the resistance to rough feeding make the meat quality of Wulian black pigs better. Fragrance."
There are also differences in feeding methods. Yangbai pigs love to feed, while Wulian black pigs should be raised in rural soils. "Resistant to rough feeding, especially love to eat. We usually press 70% of the pot, add 25% of corn, add some peanut cake. And other materials. No finished pig feed." Ma Rufeng said.
When people are complaining that pork is becoming less and less meaty, this black pork tastes the taste of the past. The price is naturally much higher, the average market price is 40 yuan a catty, four times that of ordinary pork. Although the price is expensive, there are still many people who want to taste the old taste. There are already several shops selling Wulian black pork in the urban area, which is very popular.
Ma Rufeng told reporters that the base is expanding the aquaculture area, and next year it plans to expand to 300 sows and 6,000 heads to form a relatively stable population for further purification and breeding. After the population is stable, the “base + farmer†model will be adopted to drive farmers to get rich together.
In the next step, the base will further build the “Five Lotus Black Pigâ€, a local famous product brand, to meet the needs of people pursuing natural and green food consumption, and to effectively protect local high-quality germplasm resources and promote characteristics through the development of Wulian black pig products. The development of animal husbandry.
