DETAILED DESCRIPTION

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below in conjunction with the embodiments.

[0021] As analyzed in the background technology of this application, in the prior art, betaine is easy to absorb moisture and harden during use, which increases the difficulty of its application in the production process of feed and makes it difficult to mix evenly with other ingredients, affecting its effect. At the same time, in the existing production of meat and poultry pellet feed, a certain amount of oil needs to be added to increase the energy in the feed and improve the production level of meat and poultry. Based on this, the present application provides a betaine emulsion feed additive, a preparation method and an application method thereof.

[0022] According to a typical embodiment of the present application, an emulsified liquid additive for producing poultry feed is provided, the additive comprising: a betaine solution, a fat and an emulsifier, wherein the content of betaine in the betaine solution is 10wt%~30wt%, and the fat comprises any one or more of corn oil, rapeseed oil, rice bran oil, palm oil and soybean lecithin.

[0023] The present application mixes a betaine solution, oil and emulsifier of a specific concentration, and a stable emulsified liquid can be prepared through emulsification and homogenization methods. The above-mentioned betaine emulsion product can be miscible with oil and fat, and can be added to meat and poultry pellet feed during the mixing stage of feed preparation or by post-spraying. It is easy to use and easy to disperse evenly, which is conducive to the absorption of betaine by the animals raised. It can effectively solve the problems of easy moisture absorption, easy hardening, and inconvenient use during the addition of pure betaine, and it helps to increase the energy concentration of poultry feed, reduce dust and give full play to the role of betaine in providing methyl, regulating fat metabolism, and anticoccidial.

[0024] The ratio of the betaine solution and the oil can be determined according to the requirements of the feed for oil and betaine in the prior art, thereby determining the amount of the emulsifier to emulsify the two. In some embodiments of the present application, the weight ratio of betaine solution to oil is 1:1~10, such as 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9. Within this weight ratio range, betaine can play a role and meet the oil required for meat poultry breeding, which is beneficial to increase the feed intake and weight gain of meat poultry. At the same time, betaine solution, oil and emulsifier can also form a uniform emulsion; in order to make the above-mentioned betaine solution and oil obtain better emulsification effect, the emulsifier is 1wt‰~50wt‰ of the total amount of additives, such as 5wt‰, 10wt‰, 15wt‰, 20wt‰, 25wt‰, 30wt‰, 35wt‰, 40wt‰, 45wt‰, 50wt‰ or any range between the two. Preferably, the emulsifier is 5wt‰~30wt‰ of the total amount of additives, and the emulsification effect is better.

[0025] The above-mentioned oil is preferably any one or more of corn oil, rapeseed oil, rice bran oil, palm oil and soybean lecithin, which are not only cheap and easily available, but also liked by meat and poultry animals and have high nutritional value.

[0026] The above-mentioned betaine solution can be prepared by dissolving solid betaine in water, or it can be directly from the extract of betaine or the solution separated and purified. Since artificially synthesized betaine is easy to contain impurities, there is a potential safety risk, and the separation and purification cost of high-purity betaine is high. In some preferred embodiments of the present application, the betaine solution is a natural betaine extract, which uses a natural betaine extract, and the ingredients are derived from plants. It is safer to be used for feed additives, and the direct use of the extract for the preparation of feed additives saves subsequent purification operations, which is conducive to reducing costs. Preferably, the content of betaine in the natural betaine extract is 10wt%~20wt%, which is easy to prepare, has a wide range of sources, and is easy to disperse with oils and fats to make an emulsion, with low cost and high comprehensive benefits.

[0027] The above-mentioned emulsifier can be selected from the prior art, and can be one or multiple composites. In some preferred embodiments of the present application, the emulsifier is a composite emulsifier, and the composite emulsifier preferably uses Span80 and Tween80, which has a better emulsification effect on the betaine solution and the above-mentioned oil, and is more suitable for poultry breeding. In some embodiments, the mass ratio of Span80 and Tween80 is 3:1~1:20. When mixed in this ratio, the HLB value of the composite emulsifier is 7-14.5, which can make the oil of the present application and the above-mentioned betaine solution form a stable emulsion. Exemplarily, the mass ratio of Span80 and Tween80 can be 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:12, 1:14, 1:16, 1:18, 1:20 or any range between the two.

[0028] According to another typical embodiment of the present application, a method for preparing any of the above-mentioned emulsified liquid additives is provided, and the preparation method comprises: step S1, preparing materials; step S2, adding an emulsifier to oil and fat, and stirring to obtain emulsified oil and fat; step S3, mixing the emulsified oil and fat with a betaine solution, stirring evenly, to obtain a betaine emulsion premix, wherein the content of betaine in the betaine solution is 10wt%~30wt%; step S4, homogenizing the betaine emulsion premix to obtain a betaine emulsion feed additive.

[0029] The present application uses the above-mentioned preparation method to mix a betaine solution of a specific concentration, oil and emulsifier, and a stable emulsified liquid can be obtained through emulsification and homogenization methods. The above-mentioned betaine emulsion product can be miscible with oil and fat, and can be added to meat and poultry pellet feed during the mixing stage of feed preparation or by post-spraying. It is easy to use and easy to disperse evenly, which is conducive to the absorption of betaine by the raised animals. It can effectively solve the problems of easy moisture absorption, easy hardening, and inconvenient use during the addition of pure betaine, and it helps to increase the energy concentration of poultry feed, reduce dust and give full play to the effects of betaine in providing methyl, regulating fat metabolism, and anticoccidial.

[0030] In some typical embodiments of the present application, the emulsifier in the above preparation method is a composite emulsifier composed of Span80 and Tween80. When the above composite emulsifier is used, preferably, step S2 includes: step S21, Span80 and Tween80 are mixed and stirred to obtain a composite emulsion, preferably at 30-85°C; step S22, the composite emulsion is slowly and evenly added to the oil, and stirred to obtain emulsified oil. The above steps are helpful to form a stable water-in-oil structure with better dispersion.

[0031] The above step S2 and / or step S3 can be stirred by a stirring device of the prior art, and the specific parameter setting of the stirring can be determined according to the prior art, and sufficient mixing is sufficient. In some embodiments of the present application, in step S3, the stirring speed is 7000~16000r / min, and the stirring time is 3~10min, which is the time for continuing stirring after the materials are mixed.

[0032] The above-mentioned step S4 of homogenizing the betaine emulsion premix can be carried out according to the method of the prior art. In some typical embodiments of the present application, step S4 is carried out under the conditions of a temperature of 40-75°C and a pressure of 20-50MPa, and the homogenization emulsification effect is better. In some preferred embodiments of the present application, the oil particle diameter of the emulsified liquid additive obtained after the homogenization treatment is ≤1μm, which can significantly improve the stability of the emulsified liquid additive, and can make the system stable for a longer time without stratification.

[0033] According to another typical embodiment of the present application, an application method of any of the above-mentioned emulsified liquid additives is provided, and the application method comprises: adding any of the above-mentioned emulsified liquid additives to feed for meat and poultry farming. The above-mentioned emulsified liquid additive containing betaine is conducive to the absorption of betaine by the raised animals, and can effectively solve the problems of easy moisture absorption, easy hardening, and inconvenient use during the addition of pure betaine, and is helpful to increase the energy concentration of poultry feed, reduce dust, and give full play to the effects of betaine in providing methyl, regulating fat metabolism, and anticoccidial.

[0034] The above-mentioned meat poultry include broilers, ducks and geese. Combined with the demand for oil and fat in meat poultry breeding and the application test of the above-mentioned emulsified liquid additive, it is preferred that the emulsified liquid additive is 0.1~10wt% of the feed; in order to further improve the weight gain rate, feed-to-meat ratio and other meat poultry production indicators and the comprehensive benefits of breeding, it is more preferred that the above-mentioned emulsified liquid additive is 0.1~5wt% of the feed.

[0035] Those skilled in the art know that the processing and preparation of meat and poultry feed usually includes the following steps: receiving raw materials, crushing, weighing according to the formula, mixing, granulating, post-spraying, packaging, etc. Taking into account the components and production and processing of existing meat and poultry feed, the above-mentioned emulsified liquid additive provided in this application can replace the original oil addition process and be added to the feed, such as directly adding the above-mentioned additive in the mixing stage of the above-mentioned processing process, or adding it in the post-spraying stage after the feed is granulated. Since the betaine in the above-mentioned emulsified liquid additive can be stably present in the emulsified liquid, it not only solves the problems of betaine's easy moisture absorption, easy hardening, and inconvenient use, but also through the combination with oil, there is no need to add additional processes, and it can be evenly dispersed in the feed, which promotes betaine to give full play to the role of providing methyl, regulating fat metabolism, and anti-coccidial, thereby significantly improving the feeding level and comprehensive benefits of meat and poultry.
