Abstract

The invention provides protein feed derived from rhodopseudomonas palustris and a preparation method and application of the protein feed. The protein feed is prepared from the following components inparts by weight: 90-93 parts of a broken wall thallus, 2-3 parts of lysine hydrochloride, 0.1-0.5 part of methionine, 0.1-0.5 part of threonine, 0.3-1 part of arginine, 2-3 parts of calcium hydrophosphate and 1-2 parts of calcium carbonate, wherein the broken wall thallus is the rhodopseudomonas palustris; and the preparation method includes the steps of thallus collection, lysozyme pretreatment,thallus wall breaking and formula combination, the wall breaking rate of a rhodopseudomonas palustris thallus reaches 100% by adopting the preparation method, the amino acid ratio is ideal, and the animal absorption use ratio is high. The invention further discloses application of the protein feed derived from the rhodopseudomonas palustris in duroc*(large white*landrace) ternary miscellaneous piglets, Qingyuan local pullets, carassius auratus gibelio and South American white shrimps. The protein feed is used for replacing corresponding fish meal, animal growth performance is better or not affected, and the protein feed is ideal.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed, in particular to a protein feed derived from Rhodopseudomonas palustris and its preparation method and application. Background technique [0002] Protein is the material basis for the healthy growth of animals. The protein in feed mainly comes from animal protein (such as fish meal, meat and bone meal, plasma meal, etc.) and vegetable protein (such as soybean, rapeseed, cotton seed, etc.), and there is also a small amount of microbial protein ( Such as yeast powder in breweries); animal protein has high bioavailability, but is generally expensive and limited resources, such as fish meal, which is completely dependent on marine fishing, while plant protein generally has low bioavailability and anti-nutritional factors, such as beans There are anti-nutritional factors such as tannin, phytic acid and protease inhibitors in protein, which are not good for animal growth.
