Poultry feed containing haematococcus pluvialis powder astaxanthin and preparation method

Abstract

The invention discloses poultry feed containing haematococcus pluvialis powder astaxanthin and a preparation method. The poultry feed comprises a main material and auxiliary materials, wherein the main material is flour and / or corn meal, and the auxiliary materials comprise bean pulp, calcium hydrogen phosphate and salt; the poultry feed also comprises haematococcus pluvialis powder; and the poultry feed contains 70 to 85 percent of main material, 10 to 25 percent of auxiliary materials and 5 to 10 percent of haematococcus pluvialis powder in percentage by weight, wherein the haematococcus pluvialis powder contains 0.05 to 0.5 percent of astaxanthin. A proper amount of haematococcus pluvialis powder is added in the poultry feed, the haematococcus pluvialis powder contains natural safe astaxanthin, and the astaxanthin content of the haematococcus pluvialis powder is proper, so after the poultry eat the feed, the poultry basically can lay red-core eggs with proper colors after 20 days, and the yield of the red-core eggs can reach over 99 percent; and the processing method is simple, the processing cost is low, and a raiser can process the feed by buying the haematococcus pluvialis powder with marked content.

Description

technical field [0001] The invention relates to a poultry feed, in particular to a poultry feed containing Haematococcus pluvialis powder astaxanthin for producing red eggs and a preparation method thereof. Background technique [0002] The eggs of poultry such as chickens and ducks are rich in protein, and the eggs are good in quality and cheap. Egg yolks are red hearts, which are called "red eggs". Red eggs are popular with consumers due to their good sensory perception, strong immunity, and good antioxidant properties, and their prices are relatively high; Businessmen added non-food additives such as the pigment "Sudan Red" to the daily feed of poultry for profit, and made carcinogenic red eggs, which caused social shock. The publication number is CN101617738, and the invention patent application titled "Red Mycelium Protein Feed and Its Preparation Method" discloses that 0.1 to 0.15 parts of B. trispora, Rhodotorula or Monascus have been added to the basic feed.

Problems solved by technology

Egg yolks are red hearts, which are called "red eggs". Red eggs are popular with consumers due to their good sensory perception, strong immunity, and good antioxidant properties, and their prices are relatively high; Businessmen added non-food additives such as the pigment "Sudan Red" to the daily feed of poultry for profit, and made carcinogenic red eggs, causing social shock

The publication number is CN101617738, and the invention patent application titled "Red Mycelium Protein Feed and Its Preparation Method" discloses that 0.1 to 0.15 parts of B. trispora, Rhodotorula or Monascus have been added to the basic feed. Because the red mycelium protein contains carotenoids and monascus red pigment, it is possible for the edible poultry to produce red heart eggs; the feed preparation process is complex, requiring inoculation and cultivation, and the feed production cost is high, and the pigment content in the feed is low. The effect of producing red heart eggs is not obvious
