Functional fatty powder and preparation method thereof

Abstract

The invention discloses functional fatty powder and a preparation method thereof, and belongs to the technical field of feeds. The functional fatty powder is characterized in that raw materials comprise the following components in parts by weight: 30-50 parts of concentrated omega-fatty acid fat, 10-20 parts of lecithin, 8-15 parts of concentrated linolenic acid fat, 8-15 parts of MCT, 1-5 parts of choline, 1.5-5.5 parts of nicotinamide, 1-5 parts of a composite emulsifying agent, 3-8 parts of a composite antioxidant, 2-8 parts of vitamin C, and 40-70 parts of encrusting substances or 30-60 parts of carriers. The functional fatty powder provided by the invention is small in addition quantity, high in cost performance ratio, good in stability, high in nutrient value and high in fat utilization rate; the functional fatty powder not only can greatly improve the growing property and the reproductive property of animals but also can improve the immunity of the animals and promote the development of animal organisms, so that the functional fatty powder is an excellent feed additive.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a functional fat powder and a preparation method thereof. Background technique [0002] Fat is the most important and effective energy source, adding fat to feed can provide higher energy concentration with less formula space. The purpose of using fats and oils in the feed industry is to cost-effectively increase the energy level of feed. However, with the in-depth research on fat nutrition by nutrition experts, it is found that functional fatty acids play a very important role in the growth and development of animals. [0003] At present, livestock and poultry diets are basically corn-soybean meal type, generally do not add or add a single oil (such as: soybean oil, palm oil, etc.), the fatty acid composition is unbalanced, and there is a serious lack of functional fatty acids, which is not conducive to the growth and development of animals. For example, sow diets bas...

Problems solved by technology

[0003] At present, livestock and poultry diets are basically corn-soybean meal type, generally do not add or add a single oil (such as: soybean oil, palm oil, etc.), the composition of fatty acids is unbalanced, and there is a serious lack of functional fatty acids, which is not conducive to the growth and development of animals.

For example, sow diets based on typical grains contain more long-chain polyunsaturated fats, of which ω-6 series polyunsaturated fatty acids are more, while ω-3 series polyunsaturated fatty acids are less, lacking Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) omega-3 series long-chain polyunsaturated fats and short- and medium-chain fatty acids, lecithin, which lead to omega-3 fatty acids, Lack of medium and short-chain fatty acids and lecithin, imbalance of omega-6 / omega-3 ratio affect growth performance of sows

Because the current corn-soybean meal-based feed ingredients are mainly corn oil and soybean oil, soybean oil contains about 6% linolenic acid, and omega-3 fatty acids such as EPA and DHA are zero; corn oil contains omega-3 fatty acids such as linolenic acid, EPA and DHA. 3 fatty acids are all zero, and both of them do not contain short- and medium-chain fatty acids; the omega-3 fatty acids and short- and medium-chain fatty acids in soybean oil, phospholipid oil, lard and palm oil in the daily diet are also zero, resulting in Lack of omega-3 fatty acids and short- and medium-chain fatty acids, unbalanced composition of fatty acids, affecting the growth performance of livestock and poultry; although phospholipid oil can provide a certain amount of lecithin, the quality of phospholipid oil on the market is uneven, and contains 30% soybean oil , the main fatty acid is linoleic acid, adding phospholipid oil will increase the content of linoleic acid in the diet, resulting in excess linoleic acid, in addition, the viscosity of phospholipid oil is very high, which will bring great trouble to production and use

Oil is insoluble in water, and it is difficult to emulsify and utilize in animal intestines. At present, most oils have not been emulsified and homogenized under high pressure. Even after homogenization, it is only a simple first-level homogenization treatment. low utilization
