Description

A kind of mixed type liquid additive for feed and preparation method thereof

technical field

The invention relates to a feed additive, especially a mixed liquid additive.

Background technique

In recent years, due to the improvement of breeds of farmed animals, breeds with high growth performance have emerged continuously, and the nutritional requirements of these animals have also increased. On the other hand, due to the actual needs of breeding production, the pursuit of faster growth, the protein and energy levels required for feed are getting higher and higher, and the prices of main raw materials such as corn and soybean meal continue to rise. Formulators have to increase miscellaneous meal and The use of unconventional raw materials, the energy level of these raw materials is not high, adding fat and increasing the amount of use to improve the energy level of feed is more and more used in feed formula. At the same time, the price of vegetable oil is also increasing, and the relatively low-priced mixed oil has become the main raw material used by feed mills. The composition of mixed oil is relatively complex, but they all contain a large amount of saturated fatty acids, which have long carbon chains and high melting points, are not easy to form fine emulsified oil droplets, and have a relatively low digestion and absorption rate. How to improve the absorption rate of oil has also become a problem that formulators pay attention to, so the application of feed emulsifiers is getting more and more attention.

Emulsifier is a kind of surfactant with both hydrophilic groups and lipophilic groups. It has the dual nature of hydrophilic and lipophilic, which can reduce the surface tension of oil and water, so that oil and water can blend. The emulsification of fat is to separate the fat molecules, make them minimize, and no longer form agglomerates, so that all the fat molecules lose their mutual adsorption force, flow fully, and form chyle in water without changing the chemical structure of fat molecules. Its nutritional function remains unchanged. The fats added in the feed generally include vegetable oils and animal fats. The mixed oil is a mixture of the two, and the ratio and composition are more complicated. Therefore, the choice of emulsifier must be targeted. Pure vegetable oil feed can be added with an emulsifier that has a good emulsifying effect on vegetable oil, and a compound emulsifier must be selected for mixed oil, so that the effect will be better. At present, the oil emulsifiers used by feed enterprises are mostly solid, and the addition amount is 100-200g/T. The addition amount is small, which is not conducive to uniform mixing, and the function of emulsifying oil is limited. In addition, most solid emulsifiers are fat-soluble and cannot be water-soluble. The emulsification function is in the intestinal tract of animals. Since the lipase required for fat decomposition can only work in contact with fat in aqueous solution, the emulsification effect on oil is limited. .

Feed mildew will reduce its nutritional content, and animals will not be able to obtain the corresponding nutritional content after eating. At the same time, it will also reduce the palatability of the feed, reduce animal feed intake or anorexia, and more seriously, a large amount of mycotoxins will be produced due to mildew. Death; mildew of grain can also cause serious food safety hazards. The harm of mold to grain and feed is particularly prominent. The Food and Agriculture Organization of the United Nations estimates that 15%-25% of grain in the world is polluted by mycotoxins, and the mold infection rate of feed in my country is over 90%. Therefore, mildew prevention has become a difficult task. Feed antifungal agent is a feed additive that can reduce the number of molds in feed, control the metabolism and growth of molds, inhibit the production of mycotoxins, prevent the loss of nutrients in feed storage, prevent feed mold and deterioration, and prolong storage time. At present, the addition of liquid feed antifungal agent and grease needs to be added through special equipment. For example, special pipes and nozzles are installed in the feed mixer. Installing too many pipes and nozzles is not conducive to the airtightness of the mixer. At the same time, it is affected by the mixing time. Adding liquid anti-fungal agent and grease separately will easily lead to agglomeration of materials in the mixer.

detailed description

A method for preparing a mixed liquid additive for feed, comprising the following steps:

(1) According to the proportioning of antifungal agent 40-60%, Tween 5-15%, Span 5-15%, polyethylene glycol glycerol ricinoleate 10-20%, water 5-30%, each Component weighing;

The fungicide is selected from one or more of propionic acid, benzoic acid, sodium diacetate, ammonium propionate, sodium propionate or calcium propionate

(2) Put the antifungal agent into the finished product mixing tank first, stir and mix, add formic acid or sodium hydroxide according to the pH value of the antifungal agent, adjust the pH value of the antifungal agent to 5.8-6.2, and mix evenly to obtain the antifungal agent pretreatment liquid;

(3) Add Tween, Span and polyethylene glycol glycerol ricinoleate into the emulsifier pretreatment tank, and add water, stir and mix for 5-10 minutes to obtain the emulsifier pretreatment liquid;

(4) Add the emulsifier pretreatment solution obtained in step (3) into the finished product mixing tank filled with the antifungal agent pretreatment solution, and stir for 15-25 minutes.

Wherein, in the step (2), the pH value of the antifungal agent is adjusted to 5.8-6.2, and the pH value is in the range of 5.8-6.2. The weakly acidic environment can reduce the corrosion of the propionic acid antifungal agent to the production equipment, which is conducive to the development of the propionic acid antifungal agent. The anti-mold effect of the anti-mold agent is also beneficial to the stability of the emulsifier in a weak acid environment. When the pH value of the antifungal agent is higher than 6.2, add an appropriate amount of formic acid to adjust the acidity, and when the pH value is lower than 5.8, add an appropriate amount of sodium hydroxide to adjust; Ethylene glycol glycerol ricinoleate can coexist with the antifungal agent to achieve the best effect without affecting the antifungal effect of the antifungal agent. The emulsifier can not only emulsify oil but also dissolve in water; it can increase the moisture content of the feed and prevent the feed from becoming moldy and Improve fat emulsification effect.

The usage and dosage of the mixed type liquid additive for feed of the present invention:

The dosage is: add 200g of the mixed liquid additive for feed of the present invention per 10kg of oil.

During use, according to the amount of feed oil, at first the mixed liquid additive for feed of the present invention is mixed with a certain amount of water, and the concentration of this product and water is 6-10%, that is, 600g-1000g of the feed Add 9400g-9000g of water with mixed liquid additives, mix the mixed solution with oil after mixing; spray the mixed oil mixed solution into the feed from the mixer through the oil spraying equipment of the feed enterprise; considering the feed storage Antifungal demand in the long term, the mixed liquid additive for feed of the present invention added per ton of feed is not less than 600g, considering that the excessive dosage of propionic acid antifungal agent has a certain adverse effect on the palatability of animals, adding The mixed liquid additive for feed of the present invention is not higher than 1500g. In the process of use, the present invention sprays the oil into the feed from the mixer through the feed enterprise's oil spraying equipment, avoids repeated installation of pipelines in the mixer, and saves costs.

The antifungal agent of the present invention is combined with the oil emulsifier, and the mixed liquid additive for feed of the present invention is mixed before the oil to be added during use. Since the emulsifier contains hydrophilic groups and lipophilic groups, on the one hand It can emulsify the additional water; on the other hand, the lipophilic group can emulsify the added oil, which improves the utilization rate of oil; the use of antifungal agent is beneficial to the storage of oil-containing feed. Therefore, while controlling the risk of mildew during feed storage, the present invention increases the moisture content of the finished feed product. During feed processing, appropriately increasing feed moisture can improve feed quality, increase feed starch gelatinization degree, reduce powder content and increase feed content. Durability, and can improve production efficiency.
