NOVELTY - Housefly ecology breeding using maotai-flavored liquor loss grains comprises collecting fly ovum, cleaning, feeding with milk powder and sugar, and domesticating; inducing and stabilizing fly strain in maotai-flavored liquor grains at 20-30 degrees C, relative humidity of 50-80% and water content of 50-80%, and increasing the ratio of grains to wheat bran to full-loss grain culture material; preparing industrial fly maggot protein production charge, and stabilizing the maotai-flavored liquor loss grains production fly strain; and producing fly maggot industrial product.    USE - Housefly ecology breeding using maotai-flavored liquor loss grains.    ADVANTAGE - Modern engineering technology housefly breeding has high ecological and biological utilization such as grain recycling, minimal environmental pollution, and short rotten period (7 days). The housefly cultured produces near zero discharging, has resource high added value, and high quality, scientific proportion, and fertilizer effect.    DETAILED DESCRIPTION - Housefly ecology breeding using maotai-flavored liquor loss grains comprises: (A) collecting local wild housefly, feeding with milk powder and sugar, breeding larva in bran, and naturally passing more than 5 generations for steady propagation property; (B) inducing and culturing Musca domestica larva domesticated in first step by maotai-flavored liquor loss grains at 20-30 degrees C, relative humidity of 50-80% and water content of 50-80%, increasing the ratio of grains to wheat bran from 1: 9 to full-loss grain culture material, each ratio culturing for 5-30 generations to obtain maotai-flavored liquor loss grain transformation fly strain; (C) adding alkaline to adjust the pH of grains to 6.5-7, opening for 1-6 days, flipping once a day, obtaining fly maggot protein production charge, taking (wt.%) maotai-flavored liquor loss grains production charge (60-85), wheat bran, bran coat or sugar beet pulp (10-30), and protein auxiliary material (0-10), and uniformly mixing to obtain the fly maggot protein production charge; (D) placing the fly strain larva in industrial fly maggot protein production charge, circulating for 10-15 generations to produce the fly maggot industrial product; (E) drying the residual charge generated fly maggot into biological organic fertilizer, preparing Musca domestica larva and fly in adopting biological technology processes to prepare biological medical product.
