Abstract

The invention relates to an iron phosphate feed additive, a preparation method and uses thereof, and belongs to the field of feed additive manufacture. The iron phosphate feed additive is an iron phosphate salt supported on a porous mineral material, and accounts for 1-10% of the weight of the porous mineral material. According to the preparation method, a porous mineral material is used as a dispersing agent, iron phosphate salt micro-particles synthesized by a chemical method are supported on the porous mineral material, and dry crushing or spray drying is performed to prepare the iron phosphate feed additive. According to the present invention, the iron phosphate feed additive has narrow particle size distribution, the iron pyrophosphate salt micro-particle agglomeration problem is well solved, and the prepared supported iron pyrophosphate salt has high bioavailability, can be used as the feed additive in iron supplementing of livestock and poultry, aquatic animals and the like, and can further be used for dietary phosphorus supplementing.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to an iron phosphate feed additive and its preparation method and application. Background technique [0002] Iron is an essential trace element for animals. It is an essential component of hemoglobin and myoglobin. The activity of oxidase is closely related. Iron participates in the normal transport of oxygen in body tissues, directly affects the body's ability and protein metabolism, and also affects the immune function and reproductive performance of animals. The iron content in conventional feed is relatively high, and in terms of quantity alone, it can already meet the needs of animals. However, the utilization rate of iron in plant feed is extremely low, and the degree of intensification of the breeding industry is getting higher and higher. The efforts in both breeding and nutrition have greatly increased the growth rate of livestock and poultry. Therefore, some iron must be a...
