Detailed Explanation of Efficient, High-Quality Breeding and Safe Production Technology for Hybrid-line Pigs
I. Technology Introduction: Based on Meishan pigs, combined in a hybrid cross with Pietrain, Duroc, Large Yorkshire and Landrace, this technology makes use of the Meishan pig's delicious meat and high reproductive capacity, the Pietrain's high lean meat percentage, and the fast growth and high feed conversion efficiency of Duroc, Large Yorkshire and Landrace. Without lowering production efficiency, it can raise production efficiency by improving meat quality, meet the market's new demand for meat flavor, and achieve "high efficiency, high benefit" production in the @#@227@#@ industry.
Hybrid-line meat pigs reach a market live weight of 90 kg at 160 days of age, with an average daily gain of more than 700 g during the fattening period; a feed-to-gain ratio of 2.830:1; a dressing percentage of 71.41% and a carcass lean meat percentage of 61.99%; meat color (5-point scale) 3.25 points, intramuscular fat 3.84%, excellent pork quality, and no PSE meat; it is an ideal hybrid combination with a unique flavor.
Through comprehensive comparison of the growth and development, farrowing performance and nursing results of two-way cross sows from various combinations, and of the growth rate, feed utilization, carcass lean meat percentage, meat quality and economic benefits of three-way cross commercial meat pigs, the selected three-way cross commercial pigs containing 1/4 Meishan pig bloodline showed significantly improved growth performance and carcass quality, approaching European pig breeds, while still maintaining their reproductive advantage; their shortcomings have been overcome, making them suitable for small and medium-sized intensive-management farms and household free-range rearing.
The technological results are currently actively applying for trademark protection and product patents.
II. Input Equipment and Essential Conditions: Small and medium-sized scaled farms and rural free-range households with experience in raising crossbred lean pigs, or manufacturers needing to produce @#@136@#@ high-quality flavorful pork, can all raise them, with no need for additional production facilities.
III. Market Prospects and Economic Benefits: This hybrid-line pig not only improves the carcass lean meat percentage but also retains the characteristics of Chinese local pig breeds, such as large litter size, tolerance to coarse feed and good meat flavor. It is suitable for slaughter and processing by large meat-packing plants as well as for small-package production in supermarkets, and can be sold fresh or further processed.
The commercial pigs have already been promoted and applied in 83 farming households across 3 townships; in 2004, 89,120 commercial meat pigs were marketed, with a cumulative promotion of 160,450 head and total revenue of 126.9179 million yuan. According to the "Calculation Method for Economic Benefits of Agricultural Scientific and Technological Achievements," the added net income per unit scale is 63.71 yuan/head, the economic benefit already obtained is 10.2223 million yuan, and the average annual added net income is 5.1112 million yuan. The Shanghai market requires 12 million head of live pigs each year, of which 9 million head need to be transferred in from markets in other provinces. Due to the increase in carcass lean meat percentage and dressing percentage, calculating an increase in output value of 20 yuan per commercial pig, if high-quality flavorful hybrid-line pigs account for 10%, farming households can increase their income by 18 million yuan.
