Background

Minerals are one of five nutrients required by animals, and are few but indispensable in animal bodies. The animal body contains more than 0.01% of elements called macromineral elements, including calcium, magnesium, sulfur, phosphorus, potassium, sodium and chlorine. The elements with the content less than 0.01 percent in the animal body are called microelements, and comprise 11 elements of copper, iron, manganese, zinc, cobalt, iodine, selenium, molybdenum, boron, fluorine and chromium. Different trace elements play different roles in the animal body.

Iron is a component of various oxidases such as hemoglobin, myoglobin, cytochrome enzyme and the like, and the typical symptom of iron deficiency of the body is anemia, which can cause slow growth and low immunity.

Copper plays an important role in the synthesis of heme and the maturation of erythrocytes, and copper deficiency causes anemia, with symptoms similar to iron deficiency. High doses of copper promote animal growth and increase feed utilization, but controlled amounts above a certain level can cause hemolysis and even death.

The zinc element is the composition of many enzymes in animals, more than 200 enzymes are known to contain zinc, and more than 300 enzymes have activity related to zinc. Zinc plays an important role in protecting the health of animal skin and hair, maintaining normal reproductive function, bone growth and brain nervous system growth.

Manganese, as a constituent of and an activator of enzymes, participates in carbohydrate, fat and protein metabolism, and is involved in the growth, reproduction and normal formation of bones of animals.

Selenium, vitamin E and sulfur-containing amino acid have close relationship in vivo, and participate in antioxidation and cell membrane integrity maintenance in animal body, pancreas integrity maintenance, and normal function of heart muscle and liver protection.

Iodine is a component of thyroxine, and thyroxine activates more than 100 enzymes in the body, such as cytochrome enzyme system, succinate oxidase system, alkaline phosphatase, etc., and has effects in substance metabolism, regulating protein synthesis and decomposition, promoting sugar and fat metabolism, and promoting growth and development.

Cobalt is used as a component of vitamin B12, and the main physiological function of vitamin B12 is to participate in the production of bone marrow red blood cells and prevent pernicious anemia; prevents the brain nerve from being damaged, so that the cobalt element plays an important role in the health and growth development of animals.

Chromium is mainly distributed in bones, skin, adrenal glands, brain and muscles of animals, and the physiological functions of chromium are cooperated with other substances for controlling metabolism, such as hormone, insulin, various enzymes, cellular genetic substances (DNA and RNA) and the like. Animals lack chromium, which can impede growth, shorten life, and disrupt glucose, lipid, and protein metabolism. Chromium also enhances the stress resistance and immunity of animals and improves the reproductive performance of sows.

Molybdenum is a component of xanthine oxidase/dehydrogenase, aldehyde oxidase and sulfite oxidase, and is one of essential trace elements for animals. Molybdenum and copper have a clear antagonistic relationship in absorption, and special attention is paid to the supplementation of these two elements to animals.

Boron is one of the trace elements required to maintain bone health and normal metabolism of calcium, phosphorus and magnesium. The deficiency of vitamin D is exacerbated by a deficiency of boron.

From the effects of the above-mentioned various trace elements, it is known that trace elements are important for the growth and health of animals. In the process of large-scale breeding of animals, the growth speed is high, more excrement is produced, more trace elements are discharged from the excrement, the trace elements are not absorbed from the feed per se enough, and a trace element supplement must be additionally added into the feed. The microelement additive comprises inorganic microelement additive and organic microelement additive. The inorganic trace elements have low cost, but some elements have antagonism, are used together, have low animal absorption rate and are troublesome when being used independently. The inorganic mineral feed additive and the vitamin additive are mixed and prepared, and the naked metal ions of the mineral play a role of catalysis to accelerate the oxidative deterioration of the vitamin additive, so that the inorganic mineral additive vitamin and the vitamin additive are mixed and prepared by a special processing method. Compared with the inorganic mineral feed additive, the organic trace element additive has high biological utilization rate which is 2 to 6 times of that of the inorganic mineral feed additive; the organic trace element additive is organic trace element chelate, the total charge of chelate molecules is zero, the molecular structure and chemical property are stable, the organic trace element additive is difficult to generate chemical reaction with other substances, and no interference exists among elements. Therefore, organic trace element additives are becoming increasingly popular.

Common organic trace element additives are: amino acid chelated trace elements, polysaccharide chelated trace elements, polypeptide chelated trace elements and the like. The polysaccharide chelated trace elements are low in cost and are hot spots for research and use. The invention has the Chinese patent application number CN201410463827.6, and the invention name is: a trace element-cane sugar complex feed additive, its preparing process and application are disclosed, which is an organic trace element additive prepared from cane molasses and trace elements through multi-element complexing reaction. However, cane molasses, one of the raw materials for preparing the cane molasses, has complex components, high viscosity and more water, and is not beneficial to production operation and product purification.
