Breeding and safe production technology of pigs with high efficiency and high quality

1. Technical introduction: based on Meishan pig and matched with Pittland, Duroc, Yorkshire and Landrace, Meishan pig has the characteristics of delicious meat and high fecundity, high lean percentage of Pitland, fast growth and high feed conversion rate of Duroc, Yorkshire and Landrace pigs. Under the premise of not reducing the production efficiency, we can improve the production efficiency by improving the meat quality and meet the new demand of the market for meat flavor, so as to achieve the "high efficiency and high benefit" production of @ # @ 227 meat industry.

The live weight of 160-day-old pigs is 90 kg, the average daily gain during fattening period is more than 700g, the feed-to-weight ratio is 2.830, the dressing percentage is 71.41%, the carcass lean percentage is 61.99%, the meat color (5-point system) is 3.25, intramuscular fat is 3.84%, the pork quality is good, and there is no PSE meat; it is an ideal combination with unique flavor.

Through the comprehensive comparison of growth and development, litter performance, feeding performance, growth rate, feed efficiency, carcass lean percentage, meat quality and economic benefits of three-way crossbred sows, the growth performance and carcass quality of the selected three-way hybrid commercial pigs with Meishan pig lineage 1 pedigree 4 have been significantly improved, close to European pig breeds, the reproductive advantage can be maintained, and the shortcomings can be overcome. Suitable for intensive management of small and medium-sized farms and family free-range.

Technological achievements are currently actively applying for trademark protection and product patents.

2. Input equipment and necessary conditions: small and medium-sized farms with experience in raising hybrid lean pigs and rural free-range farmers, or manufacturers who need to produce high-quality flavored pork can be raised without additional production facilities.

Third, market prospect and economic benefit: this matching line not only improves the lean percentage of carcass, but also maintains the characteristics of Chinese local pig breeds, such as high litter yield, rough feeding resistance and good meat flavor, which is suitable for slaughtering and processing in large meat factories and small packaging production in supermarkets. both fresh sale and deep processing.

There are 83 farmers in 3 townships where commercial pigs have been popularized and applied. In 2004, 89120 commercial pigs were listed, with a total promotion of 160450 pigs, with a total income of 126.9179 million yuan. According to the calculation method of Economic benefit of Agricultural Scientific and technological achievements, the net income per unit scale is 63.71 yuan, and the economic benefit is 10.2223 million yuan, with an average annual net income of 5.1112 million yuan. The Shanghai market needs 12 million live pigs every year, of which 9 million need to be transferred from other provincial markets. due to the improvement of carcass lean percentage and slaughtering rate, the output value of each commercial pig increases by 20 yuan. If the high-quality flavor matching line pig accounts for 10%, farmers can increase their income by 18 million yuan.

Fourth, the way of promotion: provide matching breeding pigs and safety production technology.
