Abstract

The invention discloses a calcium phosphate fumarate whose molecular formula is Ca 2 (C 4 h 3 o 4 )PO 4 . The preparation method of the calcium fumarate phosphate comprises the following steps: adding fumaric acid into water, then adding calcium-containing phosphate to carry out stirring reaction, adding a calcium source to control the pH to be weakly acidic, making the reaction complete, cooling and analyzing crystal, solid-liquid separation, washing, drying and pulverizing the precipitated crystal. The calcium maleate phosphate of the present invention uses calcium phosphate as the main calcium source, contains calcium and phosphorus at the same time, and has a relatively high calcium content, and the ratio of calcium to phosphorus conforms to the ratio of calcium to phosphorus in most feeds, and can synergistically absorb calcium and phosphorus in animals , good absorption effect. The invention also discloses the application of the calcium fumarate phosphate in chicken feed, which can significantly improve the egg production rate, egg weight and eggshell strength of laying hens; can significantly improve the tibia calcium content and tibia length of broilers, and can significantly improve Broiler growth performance can be promoted.

Description

technical field [0001] The invention belongs to the technical field of preparation of feed additives, in particular to calcium fumarate phosphate and its preparation method and application. Background technique [0002] Bolduan (1988) defined acidity: the number of millimoles of hydrochloric acid required to reduce the pH value of 100 grams of feed to 4.0. Laying hens suffer from indigestion due to insufficient secretion of gastric juice, often causing diarrhea or stunted growth. In order to improve the diarrhea or growth retardation of laying hens, an acidifier is usually added from an external source to reduce the pH value of the stomach of laying hens, activate the pepsin source, improve the digestibility of protein, and indirectly reduce the acidity of the feed system. Of course, coating acidifiers are also currently used to adjust the pH of the hindgut of laying hens and change the microbial flora. [0003] Fumaric acid (fumaric acid), also known as fumaric acid, viol...
