Problems solved by technology

Phytic acid can also be processed as a feed additive and added to feed, but because phytic acid is easy to complex with metal ions, phosphorus and protein in feed, the utilization rate of metal ions, phosphorus and protein is reduced, and animals lack metal Minerals are becoming more and more difficult problems in poultry farming. Too much or too little will cause harm to poultry. Moreover, phytic acid has high thermal stability and is not easily degraded by heating. It is easy to lose activity at high temperature during grain or production process
[0003] The application number is 201610739906.4, which discloses a fermented feed containing humic acid chelated trace elements and its preparation method. By inoculating strains in the medium containing humic acid chelated trace elements and then fermenting, the feed containing humic acid chelated trace elements is obtained. The technical feature of the trace element feed is that humic acid and inorganic ions of future energy elements are adjusted to pH, stirred, concentrated, added with bacteria, added with traditional Chinese medicine, and fermented to obtain it, which solves the problem of inorganic minerals in the feed. Insufficient, but there are still problems in the low utilization rate of phytate phosphorus in feed

Abstract

The invention relates to the field of feed processing, in particular to a phytase-containing chicken feed and a preparation method thereof. The chicken feed comprises the following components in partsby weight: 20 to 30 parts of soybean meal, 2 to 5 parts of corn bran, 2 to 5 parts of bran, 10 to 15 parts of a phytase solution, 5 to 15 parts of bentonite and 5 to 10 parts of salicylic acid. Afterthe exogenous phytase is added, phytic acid can be effectively degraded, the utilization rate of phytate phosphorus reaches 40-50%, the reference rate of trace elements reaches 36% or above, the phosphorus excretion of animals is reduced, and simultaneously, the phosphorus pollution to the environment is avoided, the phosphorus supply deficiency is relieved, the addition amount of phosphorus-containing feeds is saved, and the feed cost is reduced.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a phytase-containing chicken feed and a preparation method thereof. Background technique [0002] Phytic acid, also known as creatine and cyclohexyl hexa-dihydrogen phosphate, mainly exists in the seeds, roots and stems of plants, among which the seeds of legumes, the bran and germ of grains have the highest content , widely present in plant feed. Phytic acid can also be processed as a feed additive and added to feed, but because phytic acid is easy to complex with metal ions, phosphorus and protein in feed, the utilization rate of metal ions, phosphorus and protein is reduced, and animals lack metal Minerals are becoming more and more difficult problems in poultry farming. Too much or too little will cause harm to poultry. Moreover, phytic acid has high thermal stability and is not easily degraded by heating. It is easy to lose activity at high temperature during grain or produc...
