Abstract
The invention provides a grass meal fodder capable of increasing n-3polyunsaturated fatty acid content in rabbit meat, comprising based diets, grass meal with high alpha-linolenic acid content and antioxidant VE. The grass meal fodder takes native grass as fodder material without additionally adding oil, increases the n-3polyunsaturated fatty acid content in rabbit meat and has scientific and reasonable formulation, convenient preparation, easy raising, low cost and remarkable beneficial benefit.
Description
Technical field
The invention belongs to the farming and animal husbandry technical field, more specifically relate to a kind of grass meal fodder that improves n-3 polyunsaturated fatty acid in the rabbit meat.
Background technology
Studies show that leukotrienes (C18:3n3) and linoleic acid (c18:2n6) in n-3, n-6 serial polyunsaturated fatty acids are the essential fatty acids of poultry, fowl, fish, animal is preferably 1: 1 to the ratio between the requirement of the requirement of n-3 polyunsaturated fatty acid and n-6 polyunsaturated fatty acid, and is perhaps higher.But in the feed fat of routine, n-3 polyunsaturated fatty acid wretched insufficiency accounts for 55.8% as linoleic acid in the corn oil, leukotrienes only 0.7%; Soybean oil is 56.5% and 6.5%; Peanut oil is 35.3% and 0.1%; Rapeseed oil is 23.6% and 8.1%; Cottonseed oil is 62.8% and 0.N-3 polyunsaturated fatty acid of raising feeds such as the linseed oil that present people generally refine by interpolation linseed, purple perilla seed or process, fish oil.
N-3 polyunsaturated fatty acid (n-3polyunsaturated fatty acid, PUFA) comprising: alpha-linolenic acid (c18-3n3, α-Linolenic Acid is called for short α-LNA), EPA (c20-5n3, eicosapentaenoic acid) and DHA (c22-6n3).Wherein, alpha-linolenic acid is the precursor substance of EPA and DHA.
N-3PUFA has caused people's very big concern at present.Alpha-linolenic acid is the Main Ingredients and Appearance that constitutes human tissue cell, participates in synthetic, the metabolism of phosphatide in vivo, and it is the essential fatty acid that human body self can not synthesize, and can only absorb from external (food).EPA is called as " blood vessel street cleaner ", and it has dredges the cardiovascular effect of cleaning, thereby prevents multiple angiocardiopathy.And DHA is brain cell formation growth and operates indispensable material base, simultaneously also can be helpful to activating weak retina cell, mend brain brain tonic and raising eyesight thereby rise, and prevent bathomorphic effect.In addition, DHA still is a neccessary composition in the breast milk, can strengthen the human immunological competence.
In the numerous plants in the world, only there is the content of alpha-linolenic acid of minority bottle green plant higher, have exploitation and be worth, and the plant extract technical sophistication of alpha-linolenic acid, the manufacturing technique requirent height.And if adopt and in feed, directly add the n-3 polyunsaturated fatty acid, not only with high costs, and changing effect is poor in animal body, and utilization rate is low.
Summary of the invention
The purpose of this invention is to provide a kind of grass meal fodder that can improve n-3 content of polyunsaturated fatty acid in the rabbit meat, grass meal fodder provided by the invention need not additionally add special grease, utilize native grass to be feedstuff, increase n-3 content of polyunsaturated fatty acid of meat rabbit, feed formula is scientific and reasonable, easy to make, raise easily with low cost, remarkable in economical benefits.
The grass meal fodder that can improve n-3 content of polyunsaturated fatty acid in the rabbit meat of the present invention, it comprises basal diet, high alpha-linolenic acid content grass meal and antioxidant VE.
The present invention has following advantage and effect:
1, adds the meat rabbit feed that the grass meal of high alpha-linolenic acid content makes and to improve n-3 content of polyunsaturated fatty acid in the meat rabbit.
The used grass meal of general grass meal fodder comes source range very extensive, often comprises straw, straw, cornstalk, leaf, weeds and herbage etc.Wherein, herbage have nutritious, easily absorb, characteristics that output is high.In herbage variety, comprise a large amount of leguminous forages, graminous pasture and other again.Graminous pasture usually is used as the primary raw material of grass meal fodder because of the high characteristics of output.The used grass meal of the present invention is through screening, with alpha-linolenic acid content is leading indicator, select the high herbage variety of alpha-linolenic acid content, for example the alpha-linolenic acid content ratio of hybrid Chinese pennisetum, rye grass is up to 66% and 70%, and general leguminous forage has only 10%～20%.Hybrid Chinese pennisetum, rye grass output height in addition, per mu yield can reach 2000～5000kg, not only planting cost is cheap, and is the kind of the natural happiness of rabbit meat food, can be 20%～50% high alpha-linolenic acid content grass meal according to the different meat rabbit kind of raising and stage adding proportion in feed.Add the meat rabbit feed that the grass meal of high alpha-linolenic acid content makes and to satisfy the needs of meat rabbit n-3 polyunsaturated fatty acid, reach and improve rabbit meat matter, particularly improve n-3 content of polyunsaturated fatty acid 189.47%～278.95% in the rabbit meat, can also promote the meat rabbit growth, improve survival rate and economic benefit.
2, in grass meal fodder, add antioxidant VE and can significantly improve alpha-linolenic acid changing effect in the grass meal.
Meat rabbit ingests behind the feed of being made by above-mentioned grass meal, and the alpha-linolenic acid in the herbage (C18:3n3) can be converted into n-3 content of polyunsaturated fatty acid in the animal flesh.Because alpha-linolenic acid (C18:3n3) is that long-chain polyunsaturated fatty acid is easily oxidized, so the present invention adds a certain amount of antioxidant VE and can improve alpha-linolenic acid transformation efficiency 8%～15% in grass meal fodder.
3, grass meal fodder provided by the invention need not additionally add special grease, utilize native grass to be feedstuff, increase n-3 content of polyunsaturated fatty acid of meat rabbit, feed formula is scientific and reasonable, easy to make, raise (the feed method according to routine is raised) easily, with low cost, remarkable in economical benefits.
