Method for producing functional mutton by utilizing flaxseed feed

Abstract

The invention discloses a method for producing functional mutton by utilizing flaxseed feed. Fattening lambs are fed with the feed containing 8 percent of flaxseed at an appropriate time before the slaughtering, so that the mutton production performance of the lambs can be improved, and the production of high-quality mutton can be promoted; and when the fattening lambs are fed with 8 percent flaxseed feed 42 days before the slaughtering, the production performance of the fattening lambs can be improved, CLA, ALA, EPA and DHA as well as n-3 PUFA and total fatty acid content in the mutton can be increased, and the mutton quality can be improved. By adopting the method for producing the functional mutton by utilizing the flaxseed feed, the fattening lambs are fed with 8 percent flaxseed feed at an appropriate time before the slaughtering, high daily increased weight and high weight after the test can be obtained, the mutton production performance of the lambs is improved, and the production of high-quality mutton can be promoted; and when the fattening lambs are fed with 8 percent flaxseed feed 28d and 42d before the slaughtering, not only can the production performance of the fattening lambs be kept, but also excellent mutton quality can be obtained. The content of CLA, ALA, EPA, DHA, N-3 PUFA and total fatty acid in the mutton can be increased, the mutton quality can be improved, and the production of the functional mutton can be promoted.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a method for producing functional mutton by using linseed forage. Background technique [0002] With the continuous improvement of people's living standards, people put forward higher requirements for meat quality, not only requiring delicious, fresh and tender, but also emphasizing the health function of meat. Mutton is loved by consumers because of its low cholesterol, low fat, rich nutrition, and not being restricted by national culture and religious beliefs [1]. Ruminant muscle contains higher saturated fatty acids (SFA) due to hydrogenation by rumen microorganisms. The composition of food fatty acids is closely related to human health. Higher SFA can increase the content of low-density lipoprotein (LDL) in blood, make blood coagulate in blood vessels, and increase the risk of cardiovascular diseases such as atherosclerosis and thrombosis in humans. However, polyun...

Problems solved by technology

[0004] At present, the application of flaxseed mainly has problems such as long-term addition of flaxseed will reduce the feed intake and body weight of animals, the price of flaxseed is high, and long-term addition will increase feed cost and reduce feeding efficiency, which limits the use of flaxseed in the production of functional mutton. application
