Abstract

The invention belongs to the field of biological feeds, and relates to a unicellular protein feed prepared from fermented dragon fruit peel and a production method of the unicellular protein feed. The unicellular protein feed is prepared by step of fermenting mixed raw material with beneficial microbes. The mixed raw material comprises the following components in parts by weight: 2 to 60 parts of dragon fruit peel (based on completely dry material), 0.2 to 10 parts of nonprotein nitrogen source, 0.2 to 5.0 parts of phosphate, 0.1 to 3.0 parts of magnesium salt, 0 to 15 parts of adjustment agent and 40 to 98 parts of water. The production method comprises the following steps of: adjusting the pH value to 4.5 to 7.5; adding the beneficial fungicides which account for 2 to 10 percent of the total weight of the mixture and are made of beneficial microbes, wherein the total number of effective live fungicides of the beneficial fungicides is not less than 0.1 billion per gram; and mixing, carrying out fermentation cultivating, drying and smashing to obtain the unicellular protein feed. The formula is rational in design; the preparation method is scientific; the cost is low; and the unicellular protein feed can be used as a feed for animals, such as pigs, cows, sheep and chicken.

Description

technical field [0001] The invention belongs to the field of biological feed, and relates to a single-cell protein feed and a production method thereof, in particular to a single-cell protein feed fermented with pitaya peel and a production method thereof. Background technique [0002] Dragon fruit (Hylocereus undatus), also known as fairy honey fruit and red dragon fruit, is a plant of the genus Litianchi and Serpentis in the cactus family. It is native to the tropical deserts of Central America and is now cultivated in many countries in Asia. At present, my country's Hainan, Guangxi, Guangdong, Fujian and other places are planted, and the scale continues to expand. The nutritional and health benefits of dragon fruit pulp have been widely recognized and praised by the public. Pitaya peel is rich in carbohydrates such as cellulose, pectin, polysaccharides, and other substances such as flavonoids and natural red pigments, but the content of free sugar and protein is extremel...
