Introduction of Rongchang pig breeds

Rongchang pig is one of the eight best-bred pigs in the world. Rongchang pig has developed into one of the most influential local pig breeds in China.

Rongchang pig, named after its origin in Rongchang District of Chongqing, was listed in "National Breeding and Scientific Research Cooperation Plan" in 1972, 1984, 1985 and 1987, and was listed in 2000. At present, Chongqing can breed more than 200,000 sows, 220 boars, 50 core sows/kloc-0 and 20 breeding boars.

Rongchang pig is famous for its tender meat and thin skin. It has a breeding history of more than 400 years. It is said that in the late Ming and early Qing dynasties, immigrants from Guangdong and Hunan brought local pig breeds to Sichuan respectively, and they were selected to form southwest pig breeds.

The cooked meat rate of biceps femoris was 67.7%. The water content of long back muscle is 70.8%, fat is 3.2%, and protein is 24.8%. The calorific value per gram of dried meat is 5725 calories.

reproductive capacity

The estrus of boars is 62-66 days old, and they have entered sexual maturity at the age of 4 months, and they can start breeding at the age of 5-6 months. The ejaculation volume of adult boars is about 2 10 ml, and the sperm density is 80 million /ml. The average oestrus time of sows is 85.7 (71~13) days, the oestrus cycle is 20.5 (17 ~ 25) days, and the oestrus duration is 4.4 (3 ~ 7) days. The litter size, weaning survival and litter weight of primiparous sows were 6.7 0.1,6.4 0.1and 60.7±0.4kg respectively. Litter number10.2 0.1of multiparous sows with more than three births, survival number after weaning 9.7 0.2, litter weight102.2 0.6 kg.

Analysis of Rongchang Pig Breeding Prospect When it comes to Chongqing Rongchang, many people will blurt out "Rongchang Pig". Rongchang pig is one of the eight excellent local pig breeds in the world, and the three excellent local pig breeds in China are internationally recognized as valuable pig breed resources. Rongchang pig ranks first in the national local pig brand value with a brand value of 2.509 billion yuan. The "China Animal Husbandry Science and Technology Forum" approved by the Ministry of Agriculture is held in Rongchang every two years. The national pig trading market covers the whole country, and "national animal husbandry sees Rongchang" has gradually become a * * * knowledge. At the National People's Congress, Cao Qingyao also constantly recommended the business card "Rongchang Pig". He mentioned many times: "Rongchang pig is more famous than Rongchang people." This sentence has been spread in the two sessions.

Rongchang High-tech Zone was upgraded to a high-tech industrial development zone, formerly known as Chongqing Rongchang Industrial Park. Established with the approval of Chongqing Municipal People's Government in 2002, and approved as a provincial development zone in 2006. In 20 16, it was recognized as a municipal high-tech zone by Chongqing Municipal People's Government, and officially declared as a high-tech zone in the same year.

At present, there are 4 12 industrial enterprises in Rongchang High-tech Zone, including 500 enterprises in the world, 79 private enterprises in China, 79 high-tech enterprises, 37 national high-tech enterprises, 9 subsidiaries of listed companies, 6 foreign-funded enterprises and 2 GMp certified enterprises.

It is understood that the upgraded high-tech zone is named Rongchang High-tech Industrial Development Zone with a planned area of 17.05 square kilometers. It consists of five blocks and will implement the current national high-tech industrial development zone policy.

Rongchang, Hualuo, is a high-tech zone with characteristics of agriculture and animal husbandry in China. It is a good opportunity for Rongchang. How to seize this opportunity and promote the development of Rongchang? Cao Qingyao, deputy to the National People's Congress and secretary of Chongqing Rongchang District Committee, who is attending the National People's Congress in Beijing, said that there are hundreds of high-tech zones in China, but most of them are engaged in industry, and this high-tech industrial development zone in Rongchang is a high-tech zone featuring agriculture and animal husbandry in China, which is also the spirit of Chongqing's implementation of the spirit of the 19th Party Congress and the call for high-quality development issued by the general secretary when attending the deliberation of the Inner Mongolia delegation.

It is suggested that Rongchang pig 1 should be protected.

In summer and autumn, planting gourd, big melon, sleeping melon, sunflower and other plants outside the pig house can shade and cool down. In winter, plastic greenhouse feeding technology should be popularized, and insect repellent and immunization work should be done regularly.

2. Promote high-density breeding pigs.

0.8m2 pigpen in winter 1 fattening pig, summer 1 pigpen 1 fattening pig. High-density breeding pigs not only have few laps and low cost, but also fatten pigs compete for food. Sleep when there is no activity place, love to gain weight, gain weight quickly, and reduce feeding expenses.

3. After the fattening pigs exceed 90kg, the daily weight gain rate obviously slows down, and fat deposition is the main factor, which makes it more uneconomical to feed, and the fat increases, making it difficult to sell; Slaughtering under 90 kg, although the feed utilization rate is high, is uneconomical because of its small weight and low meat yield. Generally, 90 ~ 120 kg of fattening pigs is suitable for slaughter.

4, the variety should be excellent

First of all, we should choose varieties according to market demand. At present, to promote multi-hybridization, it needs at least three yuan, preferably five yuan. For example, the British pIC pig, five lines, has a fast growth rate, and can reach 1 10 kg in 58 days, with a lean meat rate of 66% and a feed-meat ratio of 2.8: 1.

5, fence should be simple

Don't make the pigsty too luxurious, just keep warm and ventilated.

6, epidemic prevention should be strict.

Pay attention to disinfection, not only to prevent foreign diseases, but also to prevent fecal pollution and spread diseases, and inject vaccines according to immunization procedures.

7, slaughter should be timely

For example, the weight of binary pig reaches 70 kg, the inner ternary 80-85 kg, the outer ternary 95 kg, and the British pIC pig 105 kg is the timely weight of slaughter. In addition, when the pig market price is high, the heavier the weight, the better; When the price is low, it's best to be light, so as to reduce feed consumption and cost.

8. "Feed the pig backwards".

In view of the above shortcomings, combined with the growth law and characteristics of pigs, a new method of raising pigs was determined, that is, from piglets to middle pigs. That is, before 50-60 kg, concentrate with high energy and high protein is the main material, supplemented by necessary feed additives and a small amount of green feed. From the middle pig to the slaughter stage, the input of concentrated feed should be appropriately reduced, and the ratio of green feed to roughage should be increased: concentrated feed 60%, green feed 25%, roughage 15%. This method not only shortens the feeding cycle of pigs, but also makes full use of a large number of green feed and roughage resources, thus saving the amount of concentrated feed and greatly improving the economic benefits.
