Feed

Abstract

The invention discloses a feed. The feed is characterized by being prepared from by steps: (a) preparation of a fermentation raw material, to be specific, proportionally adding culture solution to feathers to obtain a fermentation raw material; (b) inoculation of a strain capable of degrading the feathers, to be specific, inoculating the obtained fermentation raw material with bacillus paramycoides in a nucleotide sequence shown as SEQ ID NO.1; (c) fermentation, to be specific, fermenting for 20H-80H at 30-45 DEG C under the condition that a PH value is 5-8, so that liquid feed is obtained after fermentation; (d) preparation of solid feed, to be specific, adding a base material into the obtained liquid feed according to a certain proportion, and drying to obtain the solid feed. The feed ishigh in nutrient content, especially high in content of amino acid components and suitable for preparation of preparation of feed or other nutrient products. The feed is mainly prepared from the feathers, so that the feathers are recycled effectively, waste of the feathers is reduced, and the problem of difficulty in treatment of the feathers is solved.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a feed. Background technique [0002] In recent years, my country's poultry breeding industry has developed rapidly. Feathers can account for 5%-7% of the weight of broilers, and the annual output exceeds 1 million tons. Waste, and seriously pollute the environment, and even spread diseases, causing Newcastle disease, air bag inflammation and keratoconjunctivitis. health problems. At present, physical and chemical methods such as high temperature and high pressure, strong acid and alkali, and extrusion are usually used to treat feathers. The process is complex, consumes a lot of energy, and is easy to cause environmental pollution. Therefore, if feathers can be recycled, environmental pollution will be reduced, resources will be saved, and the sustainable development of my country's resources will be promoted.

Problems solved by technology

[0002] In recent years, my country's poultry breeding industry has developed rapidly. Feathers can account for 5%-7% of the weight of broilers, and the annual output exceeds 1 million tons. However, most of them are not utilized and are usually landfilled or incinerated. Waste, and seriously pollute the environment, and even spread diseases, causing Newcastle disease, air bag inflammation and keratoconjunctivitis. health problems

At present, physical and chemical methods such as high temperature and high pressure, strong acid and strong alkali, and extrusion are usually used to treat feathers. The process is complicated, consumes a lot of energy, and is easy to cause environmental pollution.
