Abstract
The invention discloses a compound emulsifier for animal feeds, which is prepared by the raw materials based on the parts by weight as follows: 20-25 parts of sugar esters (SE)-5, 40-60 parts of SE-13 and 20-30 parts of monoglyceride. The emulsifier of the invention has good emulsifying effect and low production cost; in addition, the raw materials are solid powder in the physical form, are free of toxicity and peculiar odors and are convenient to add. The emulsifier of the invention is added into the daily rations of animals for feeding and metabolism tests. In the broiler feeding test, the average daily gain of the broilers is increased by 7.0%, the feed to gain ratio is decreased by 4.44%, the utilization ratio of the crude fat is increased by 1.81% and the utilization ratio of the crude protein is increased by 5.8%. Compared with the feeds using compound agents of single emulsifiers in the prior art, the feeds in the invention enjoys that the production properties and the nutrient utilization ratios are improved to different degrees.
Description
Technical field
The present invention relates to a kind of emulsifying agent, specifically a kind of compound emulsifier for animal feeds.
Background technology
In pursuing the modern animal husbandry of culturing efficient, grease is as a kind of energy source of high heat, and the interpolation in feed is more and more general; But additive effect is but often undesirable, and reason is the livestock and poultry that grow fast; Especially children's age meat livestock and poultry, various digestive organs are grown imperfect as yet, and are therefore limited to the digestibility of fat; Cause the huge waste of high energy feed, increased aquaculture cost, and can increase environmental pollution.So in feed, adding the exogenous emulsifying agent with the absorption of promotion fat digestion becomes a kind of inevitable.
What the exogenous emulsifying agent that in feed, adds at present was maximum is soybean lecithin.The research of the emulsifying agent that carried out then concentrates on phosphatide and cholate, but the phosphatide emulsifying effectiveness is limited, and it is too high that cholate is produced cost, also is mainly used in medicine and health products now, and large-scale application does not also possess economic advantages in feed.
Therefore be badly in need of a kind of emulsify well at present, the animal and fowl fodder that efficiency of feed utilization is high is used emulsifying agent.
Summary of the invention
The object of the present invention is to provide a kind of emulsify well, efficiency of feed utilization is high, compound emulsifier for animal feeds with low cost.
For realizing above-mentioned purpose, invention thinking of the present invention is:
In feed, add by the composite a kind of compound emulsifying agent of the emulsifying agent that respectively has suitable hydrophilic lipophilic balance (HLB); Both can bring into play and strengthen functional advantage separately; Replenish shortcoming each other; Can solve in the emulsion process with best proportioning again simultaneously, the variation of phase, problem of unstable take place in emulsion easily.Sucrose fatty ester (SE) is a series of general names with fatty acid ester of different hydrophilic lipophilic balance value (HLB); The SE of different HLB values is used the compound emulsifying agent that can obtain any HLB value between 2～16; Monoglyceride HLB value 4.9～5.3; Monoglyceride and SE are used that can to obtain emulsifying effectiveness better, the compound emulsifying agent product that the emulsification threshold value is wideer.
Concrete technical scheme of the present invention is:
A kind of compound emulsifier for animal feeds, it is to be processed by following raw materials in weight portion:
20～25 parts of sucrose fatty ester SE-5
40～60 parts of sucrose fatty ester SE-13
20～30 parts of monoglycerides.
Above-mentioned a kind of compound emulsifier for animal feeds, optimum weight part proportioning of its raw material is:
20 parts of sucrose fatty ester SE-5
40 parts of sucrose fatty ester SE-13
20 parts of monoglycerides.
The HLB value of above-mentioned sucrose fatty ester SE-5 is 5; The HLB value of sucrose fatty ester SE-13 is 13.Said sucrose fatty ester SE-5 is that the HLB value is 5 sucrose fatty ester, and other in like manner.
A kind of compound emulsifier for animal feeds, it is to be processed by following raw materials in weight portion:
20～25 parts of sucrose fatty ester SE-5
10～25 parts of sucrose fatty ester SE-7
40～60 parts of sucrose fatty ester SE-13
20～30 parts of monoglycerides.
Above-mentioned a kind of compound emulsifier for animal feeds, optimum weight part proportioning of its raw material is:
20 parts of sucrose fatty ester SE-5
10 parts of sucrose fatty ester SE-7
40 parts of sucrose fatty ester SE-13
20 parts of monoglycerides.
The HLB value of above-mentioned sucrose fatty ester SE-7 is 7.
Its concrete preparation method of above-mentioned compound emulsifier for animal feeds is:
(1) distinguish each raw material of weighing according to the above ratio:
(2) above-mentioned raw materials is mixed, mix and get final product;
(3) packing.
Above-mentioned steps (2) is because raw materials used unit weight is close, need not to consider sequencing so feed intake when mixing.Step (3) divides loading amount according to producing and the decision of sale needs, generally can be 5kg, 25kg packing.
This product places shady and cool dry place to preserve when preparation is accomplished the back or do not used and gets final product.
The present invention advises method for using: add compound emulsifying agent 400～1200g of the present invention in the mixed feed per ton.
Advantage of the present invention and benefit:
The present invention selects sucrose fatty ester SE-5, sucrose fatty ester SE-13 and monoglyceride as the emulsifying agent raw material; It is better to add sucrose fatty ester SE-7 effect; Produce synergy between each raw material, can bring into play and strengthen functional advantage separately, can solve in the emulsion process with best proportioning again simultaneously; The variation of phase, problem of unstable take place in emulsion easily.Emulsifying agent emulsify well of the present invention, cost of manufacture is low, and the raw material physical form all is solid powdery, and is nontoxic, no special odor, it is convenient to add.In livestock and poultry diet, add emulsifying agent of the present invention and do raising and metabolic test, in the feeding of broiler test, make the fryer average daily gain improve 7.0%, the material anharmonic ratio descends 4.44%, and the crude fat utilization rate improves 1.81%, crude protein utilization rate raising 5.8%.Use single emulsifying agent complex agent type feed to compare in the present invention and the prior art, production performance and utilization of nutrients all have raising in various degree.
Below in conjunction with preferred forms the present invention being further specified, so that the public has whole and sufficient understanding to summary of the invention, and is not the qualification to protection domain of the present invention.Aforementioned part fully discloses the protection domain that the present invention can implement, and therefore allly any well known in the artly is equal to replacement according to what the disclosure of invention was carried out, all belongs to infringement of the present invention.
