Problems solved by technology

[0003] The disadvantage of the above-mentioned first product is that the absorption rate of this inorganic form of trace elements in the animal body is often very low, and a large amount of trace elements are finally excreted into the environment through feces, which not only causes the loss and waste of trace elements, but also pollutes the environment. surroundings
The disadvantage of the second product is: In order to improve the absorption rate of trace elements, people have developed organic trace element products, which can improve the absorption rate and reduce environmental hazards
However, the production cost of this single high-purity organic trace element product is relatively high, which seriously inhibits the application and promotion of this type of product

preparation example Construction

[0010] When preparing the yeast autolysate premix of the present invention, a predetermined amount of the above-mentioned trace element salts can be directly added to the autolyzed yeast self-solution, and then the mixed solution is adjusted to a suitable pH value with water and acid / alkali and concentration, and then react at a suitable temperature for a period of time. The trace element salts can also be added in solution. In an alternative embodiment, the preparation method includes the following steps: (1) providing a required amount of pH and concentration adjusted trace element salt solution; (2) providing a solution of yeast autolysate, and adjusting the pH and concentration to Appropriate value; (3) Mix the solutions obtained in steps (1) and (2), and react at an appropriate temperature, so that the trace elements are combined with the organic matter in the autolyzed matter.

[0011] Yeast autolysis treatment methods are well known in the prior art. The reaction used...

example

[0014] Below with the premix of 1% of consumption in the broiler chicken 0-4 weeks special type feed formula, used inorganic salt is sulfate, and the bacterial classification of used yeast self-solution is active brewer's yeast (Saccharomyces cerevisae, crude protein is 45%), Take the production of 1000 kg of products as an example to elaborate the detailed production plan.

[0015] The proportions of copper, iron, manganese and zinc contained in the feed formula are 8mg / kg, 80mg / kg, 60mg / kg and 40mg / kg. For the premix mixed with the feed at a weight ratio of 1%, copper, The contents of iron, manganese and zinc should be 800mg / kg, 8000mg / kg, 6000mg / kg and 4000mg / kg respectively, and the raw materials of copper sulfate, ferrous sulfate, manganese sulfate and zinc sulfate should be 1969mg / kg, 21714mg / kg and 16472mg respectively / kg, 9908mg / kg, the converted percentages are 0.20%, 2.17%, 1.65%, 0.99%. The dry matter raw material of the yeast autolysate used is 1-0.20%-2.17%-1.65...

Abstract

The invention provides an animal feed premix containing multiple microelements, which is characterized by containing microelements such as cooper, iron, manganese and zinc and yeast autolysate, wherein the proportion of four microelements is prepared according to the feeding standards of different animals, and the microelements and the yeast autolysate react to form a compound good for the absorption of the animal. The invention also relates to a preparation method of the premix, comprising the steps of reacting the salts containing microelements such as cooper, iron, manganese and zinc with the yeast autolysate, and converting the microelements into easily absorbed compound. The invention can meet the requirements of multiple microelements for the animals and increase the absorption rate, reduce the environmental harm and the using cost of products..

Description

technical field [0001] The invention relates to an animal feed additive, more specifically to a premix containing trace elements and yeast autolysate. Background technique [0002] Animal growth requires a variety of trace elements, therefore, it is necessary to add an appropriate amount of various trace elements to animal feed. At present, there are mainly two ways to add trace elements. The first is inorganic trace element premix, that is, various inorganic salts are formulated and mixed according to the needs of animals, and then added to animal feed to meet the physiological needs of animals, such as The development of copper-yeast powder pig feed additive of people such as Li Sanqiang, Northwest Agricultural Science Journal, 1993, 2 (4): P 85-88 discloses. The second is an organic product containing a single trace element, such as amino acid chelate zinc glycinate, iron methionine, etc. This type of product is added to the inorganic trace element premix by single addi...
