Problems solved by technology

However, due to the lack of research and application of nutritional technology and feed preparation technology for Yanan pigs, feed preparation is done with reference to the nutritional parameters of foreign pig breeds or other local pig breeds, resulting in the nutrients in the feed not being able to fully meet the needs of Yanan pigs. Growth needs, and the excellent characteristics of Yanan pigs, such as roughage resistance, strong disease resistance, and delicious meat, have not been fully explored and utilized. At the same time, it has led to a great waste of feed resources and human resources, seriously threatening the development and utilization of excellent pig breeds, affecting Economic benefits for farmers

Abstract

The invention discloses a feed capable of reducing Yanan pig back-fat thickness and improving Yanan pig lean meat deposition rate. The feed comprises following components in percentage by weight: 55 to 75% of starch type feed, 15 to 20% of protein feed, 1 to 3% of grease, 8 to 15% of fiber feed, 1 to 5% of composite mineral elements and 0.3 to 0.6% of vitamin composite. Through years of practice, researches on nutrition requirement of Yanan pigs, nutrition and meat quality, and exploitation and utilization of novel feed resources, the components and ratio of the Yanan pig feed are scientifically adjusted, so that the utilization rate of the feed is increased, the immunity ability and the health conditions of the Yanan pigs are improved, the back-fat thickness of the Yanna pigs is reduced, and the protein deposition rate and lean meat ratio of the Yanan pigs are increased. Thus the Yanan pork has the advantages of tenderness, redness, and fresh and delicious taste, and the economic efficiency of the breeders is prominently increased.

Description

technical field [0001] The invention relates to a feed for reducing the backfat thickness of Yanan pigs and improving the lean meat deposition rate of Yanan pigs. Background technique [0002] Yanan pig is a famous local black pig breed in China, which was first included in the "List of China Livestock and Poultry Genetic Resources". It is one of the main local pig breeds raised in the hilly areas of Sichuan. Because of the advantages of roughage resistance, stress resistance, moisture resistance, disease resistance, delicate and delicious meat, and high unsaturated fatty acid content, the Yanan pig breed is deeply loved by farmers and consumers. However, due to its low lean meat rate of less than 40%, and a fat rate of more than 35%, the meat yield and breeding benefits are not high, which severely limits the retention and utilization of high-quality genetic resources of Yanan pigs. [0003] In recent years, pig production has developed rapidly, especially the wide applica...
