Tea feeds and preparation method

Abstract

The invention discloses tea feeds and a preparation method. The preparation method comprises the following steps of 1, crushing tea waste, spraying water until the humidity is 15 to 25 percent, adding a combined strain of trichoderma, aspergillus niger and aspergillus oryzae, and performing piling and fermentation; 2, drying and crushing the fermented tea waste; 3, uniformly blending 100 weight parts of fermented tea waste, 20 to 100 weight parts of grain feed and 0.5 to 10 parts of yeast, spraying water until the humidity is 15 to 25 percent, simultaneously adjusting a pH value to be 4.5 to 6, and performing secondary fermentation for 3 to 4 days at 40 to 55 DEG C; 4, spreading the fermented mixture for cooling, and drying and crushing the mixture to obtain the tea feeds. According to the tea feeds and the preparation method, the effects of ordinary tea feeds of improving the disease resistance of livestock and poultry, increasing the egg and milk yield, enhancing the quality of meat and reducing the fishy smell and urine odor are maintained; in addition, every gram of selenium-rich tea waste contains 0.02 to 0.1 microgram of selenium, so that anti-oxidation effects are further improved; moreover, selenium-P proteins have the effects of chelating toxic substances such as heavy metal and reducing the toxicity of the toxic substances.

Description

technical field [0001] The invention relates to a tea feed, in particular to a tea feed and a preparation method thereof. Background technique [0002] At present, waste tea materials such as waste tea leaves, tea stalks, tea dregs, and tea pomace are produced in the production of tea leaves and tea oil, and the protein content in these waste tea materials can reach more than 17%, and the amino acid lysine and The ratio of methionine is reasonable, respectively 17.5% and 0.54%. However, the waste tea material contains high tea polyphenols, which taste bitter and astringent. The tea seed cake contains tea saponin, which is hemolytic, and the crude fiber content in the waste tea material is also high, so it can be used directly without treatment. Feed can affect the health of livestock. [0003] In the Chinese patent document CN101700097A, a method for preparing tea feed through two fermentations is proposed. After testing, it can effectively increase the crude protein conte...
