Abstract

The invention discloses a daily fodder for increasing polyunsaturated fatty acid in mutton sheep and a preparation method and application thereof, and belongs to the field of fodders. The daily fodder is prepared by mixing concentrated fodder with coarse fodder according to a weight ratio of dry matter, wherein the weight ratio is 50:50. The concentrated fodder is prepared from, by weight, 20-30 parts of corn, 1.5-2.5 parts of schizochytrium limacinum powder, 5-12 parts of soybean meal, 2-3 parts of a mutton sheep composite premix, 0.01-0.025 part of an antioxidant, 1-10 parts of DDGS and 2-7 parts of fermented fodder. The coarse fodder is forage grass. The ratio of the concentrated fodder to the coarse fodder is 50:50, it is ensured that the daily gain of the fed sheep is 150 g or above, and the expected daily gain target is achieved; moreover, effective synergism of components such as the schizochytrium limacinum powder and the fermented fodder is realized, and the content of unsaturated fatty acids such as CLA, DHA and EPA in mutton organism tissue is obviously increased.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a diet for increasing polyunsaturated fatty acids in mutton sheep and its preparation method and application. [0002] technical background [0003] Docosahexaenoic acid (DHA) is a long-chain polyunsaturated fatty acid of the omega-3 series, mainly derived from deep-sea fish oil and seaweed. DHA has important physiological functions to the human body, such as promoting brain development, protecting eyesight, inhibiting cardiovascular diseases, anti-cancer, anti-inflammation and so on. It is also known as "brain gold" because it is crucial to the intelligence and vision development of fetuses and babies. [0004] EPA is the English abbreviation of eicosapentaenoic acid, which belongs to the omega-3 series of polyunsaturated fatty acids and is an essential fatty acid for human body. EPA can help reduce the content of cholesterol and triglycerides, and promote the metabolism of satu...
