Abstract
The present invention belongs to the technical field of feed, and specifically discloses a functional fat feed additive and a preparation method thereof. The functional fatty feed additives mainly comprise the following components in parts by weight: linoleic acid 15-25 parts, arachidonic acid, 2-10 parts, alpha-linolenic acid 8-10 parts, eicosapentaenoic acid 5-10 parts, docosahexaenoic acid 5-10 parts, docosapentenoic acid 2-8 parts, and vitamin C1 1-5 parts. The omega-6 and omega-3 polyunsaturated fatty acid are used to prepare a fat feed additive microcapsule by applying the microencapsulation technique, which not only improves the addition ratio of omega-3 polyunsaturated fatty acid of the daily ration, but also maintains a suitable ratio between omega-6 and omega-3 polyunsaturated fatty acids of the daily ration, makes full use of the nutritional efficacies of omega-6 and omega-3 polyunsaturated fatty acids, improves the immunity of animals, and improves the growth and reproductive performance of animals.
Description
Technical field
The invention belongs to field of feed, particularly, disclose a kind of feed fat powder feed addictive and preparation method thereof.
Background technology
Aliphatic acid not only can provide energy for animal, also has special physiological function, and dissimilar aliphatic acid, and its physiological function is different.Position according to the length of fatty acid chain, saturation degree and double bond can be categorized as saturated fatty acid and unrighted acid, wherein unrighted acid also can be divided into monounsaturated fatty acids and polyunsaturated fatty acid, and polyunsaturated fatty acid also can be divided into omega 6 polyunsaturated fatty acid and omega-3 polyunsaturated fatty acids.Omega-fatty acid, particularly long-chain polyunsaturated fatty acid (as EPA and DHA), be considered to functional nutrient.DHA has important effect to brain tissue and neural growth, and supplementing the raising of DHA to intelligence has good effect.In animal productiong, DHA can reduce the death that newborn piglet causes greatly owing to suffocating.In sow diets, add EPA and DHA can improve fertility of sow and healthy and newborn piglet growth performance, immune state and vigor.Current livestock and poultry diet is corn-soybean meal substantially, and generally do not add or add single grease (as: soya-bean oil, palm wet goods), omega-fatty acid content is lower, and when causing animal to be born, vigor is poor, and the death rate is high.
