Problems solved by technology

[0006] The current methods of iron supplementation have many disadvantages. Firstly, iron-containing compounds have different chemical characteristics, and have different absorption and transport channels in animals. Using a certain iron preparation alone has a single absorption method and a low absorption rate. secondly, ferrous sulfate, ferrous fumarate and ferrous glycinate are all ferrous iron, which is unstable and easily oxidized into ferric iron, which greatly reduces the absorption rate; finally, the iron supplement product is untreated, and the iron Strong fishy smell, affecting animal palatability and reducing animal feed intake

Embodiment 1

[0045] A mixed feed additive for preventing iron deficiency anemia, which is composed of the following raw materials in weight percentage: 46% ferrous fumarate, 10% ferrous lactate, 25% ferrous glycinate, 7% L-ascorbic acid, thiamine hydrochloride 0.6%, cyanocobalamin 0.06%, acidity regulator 6%, and flavoring agent 5.34%. The preparation method is to crush the above materials into fine powders with a fineness above 100 mesh, weigh them in proportion, mix them uniformly, and then Add binder to make soft material, granulate with 60-80 mesh sieve, dry at 45°C-55°C for 1.5-3.5 hours, dry until the moisture content of the granules is below 10%, and pass through a 60-80 mesh sieve Whole grains are finished products. The mixed feed additive contains 20.3% iron, and is added to the basic ration at a ratio of 0.05% of the mass of the basal ration for animals to eat.

Embodiment 2

[0047] A mixed feed additive for preventing iron deficiency anemia, which is composed of the following raw materials in weight percentage: 52% ferrous fumarate, 9% ferrous lactate, 22.5% ferrous glycinate, 6.5% L-ascorbic acid, thiamine hydrochloride 0.5%, cyanocobalamin 0.05%, acidity regulator 5%, and flavoring agent 4.45%. The preparation method is to crush the above materials into fine powders with a fineness above 100 mesh, weigh them in proportion, mix them uniformly, and then Add binder to make soft material, granulate with 60-80 mesh sieve, dry at 45°C-55°C for 1.5-3.5 hours, dry until the moisture content of the granules is below 10%, and pass through a 60-80 mesh sieve The whole grain is the finished product. The mixed feed additive contains 21.5% iron, and is added to the basal ration at a ratio of 0.0475% of the mass of the basal ration for animal consumption.

Embodiment 3

[0049] A mixed feed additive for preventing iron deficiency anemia, which is composed of the following raw materials in weight percentage: 58% ferrous fumarate, 8% ferrous lactate, 20% ferrous glycinate, 6% L-ascorbic acid, thiamine hydrochloride 0.4%, cyanocobalamin 0.04%, acidity regulator 4%, flavoring agent 3.56%, its preparation method is to crush the above materials into fine powders with a fineness above 100 mesh respectively, after weighing in proportion, mix evenly, and then Add binder to make soft material, granulate with 60-80 mesh sieve, dry at 45°C-55°C for 1.5-3.5 hours, dry until the moisture content of the granules is below 10%, and pass through a 60-80 mesh sieve Whole grains are finished products. The mixed feed additive contains 22.7% iron and is added to the basic ration at a rate of 0.045% of the mass of the basal ration for animals to eat.

Abstract

The invention discloses a mixed feed additive for preventing iron deficiency anemia and a preparation method thereof, belonging to the field of animal feed additives. The mixed feed additive comprises 46 to 70% of ferrous fumarate, 6 to 10% of ferrous lactate, 15 to 25% of ferrous bisglycinate, 5 to 7% of L-ascorbic acid, 0.2 to 0.6% of aneurine hydrochloride, 0.02 to 0.06% of cyanocobalamin, 2 to 6% of an acidity conditioning agent and 1 to 6% of a flavoring agent. The preparation method comprises the following steps: crushing the above materials into fine powder with a particle size of 100 meshes or above; weighing the materials according to the above proportions and carrying out uniform mixing; then adding an adhesive to prepare a soft material; subjecting the soft material to granulation with a 60-to-80-mesh sieve; carrying out drying at 45 to 55 DEG C for 1.5 to 3.5 h until moisture content of particles is 10% or below; and grading dry particles with the 60-to-80-mesh sieve so as to obtain the finished mixed feed additive. The mixed feed additive has the beneficial effects that the ratio of all the components is appropriate; divalent iron is protected from oxidation after granulation; and as 0.04 to 0.05% of the additive is added into a mixed feed, iron deficiency anemia of animals can be efficiently improved.

Description

technical field [0001] The invention relates to the field of animal feed additives, in particular to a mixed feed additive for preventing iron deficiency anemia. Background technique [0002] Blood is composed of plasma and blood cells. Blood cells include red blood cells, white blood cells and platelets. The main component of red blood cells is hemoglobin, which accounts for about 32% of its wet weight and 97% of its dry weight; hemoglobin is composed of globin and heme. Each hemoglobin The element is composed of four pyrrole subunits to form a ring, and the center of the ring is a ferrous ion. Iron is an important raw material involved in hematopoiesis. [0003] The average lifespan of red blood cells is 120 days, and a certain number of red blood cells are renewed every day. Under normal physiological conditions, red blood cells have a certain shape structure and a relatively stable number. Anemia refers to a state in which red blood cells in the blood are less than norma...
