Problems solved by technology

But this method can't be applied to industry, reason is as follows: (1) reaction time is very long, and the output in the unit body container is very low, and production efficiency is extremely low; The yield is low; (3) the raw material cost is higher with pure ethanol, and at the same time, the requirements for reaction equipment are relatively high; (4) ethanol has a low boiling point, is volatile, has a large safety hazard, and is easy to cause explosion or fire; (5) The cost of ethanol recovery is high; (6) the solubility of the by-product sodium chloride in ethanol is not high, resulting in high impurity content in the product

Abstract

The invention discloses a method for preparing manganese nicotinate. The method includes steps of adding nicotinic acid into water; adding manganese sources into the water and carrying out stirring reaction; carrying out cooling after the reaction is sufficiently completely carried out; separating solid from liquid; washing and drying obtained solid products to obtain the manganese nicotinate. ThepH (potential of hydrogen) values of reaction systems are controlled in whole procedures during stirring reaction, so that the reaction systems are weakly acidic. The invention further discloses application of the manganese nicotinate to animal feed. The method and the application have the advantages that the method is simple, is short in reaction time, low in cost and high in production efficiency and only has low requirements on equipment, the manganese nicotinate which is a product prepared by the aid of the method is high in yield and purity, the yield can reach 95% at least on the basisof manganese, and the purity of the product can reach 98% at least; excellent growth promoting effects can be realized for poultry animals when the manganese nicotinate is used in poultry feed, and the quality of carcasses can be improved; the reproductive performance of reproductive sow can be particularly greatly improved when the manganese nicotinate is used in pig feed; effects of obviously improving the growth performance and reducing the death rates can be realized when the manganese nicotinate is used in aquatic feed; effects of increasing the milk quantities of ruminant animals and reducing the mastitis incidence can be realized when the manganese nicotinate is used in ruminant feed.

Description

technical field [0001] The invention belongs to the field of preparation of feed additives, in particular to a preparation method of manganese nicotinate and the application of manganese nicotinate in animal feed. Background technique [0002] Manganese is a component of arginase, prolinase, RNA polymerase, manganese-containing superoxide dismutase (Mn-SOD), pyruvate carboxylase, etc. Activator of enzymes, transferases, and hydrolases. The absence of manganese in animals results in decreased feed intake, slower growth, lower feed utilization, bone abnormalities, ataxia, and reproductive dysfunction. [0003] Niacin is 3-picolinic acid, also known as nicotinic acid. It is a vitamin with the simplest structure and the most stable physical and chemical properties. It is an indispensable nutrient in humans and animals. The function of cell metabolism and expansion of blood vessels can promote the growth and development of human and animals, and is an indispensable food and fee...
