Tea seed dreg pig feed

Abstract

The invention relates to the technical field of livestock breeding and in particular relates to a tea seed dreg pig feed and a preparation method thereof. According to the method disclosed by the invention, the tea seed dreg pig feed is prepared by proportional compatibility of tea seed dregs and distiller grains serving as main raw materials as well as glycosidase, cellulase, chamomile, willow barks, dill, geranium, oenothera biennis, thyme and sweet potatoes as auxiliary materials, and tea seed dregs are fermented by using a beer yeast, aspergillus niger and pichia pastoris, so that the content of beneficial components in the tea seed dregs is increased, the tea seed dregs are easier to digest, part of tea saponin in the tea seed dregs is degraded, a small amount of tea saponin is only remained, the effects of all the raw materials are sufficiently exerted, the tea seed dregs and the distiller grains are sufficiently utilized, the pork of the raised pigs contains intramuscular fat and is fine and smooth in meat quality and prominent in flavor, and the tea seed dreg pig feed is mainly prepared from the tea seed dregs and the distiller grains and is good in palatability and safetyand uniform in nutrient.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to tea seed meal pig feed and a preparation method thereof. Background technique [0002] Tea seed meal is also called tea bran and tea seed cake. The particles are purple-brown. It is a by-product of oil extraction from camellia oleifera seeds. It is rich in nutrients and high in value, and can be used as animal feed. [0003] Tea seed meal contains many nutrients such as protein, fat, starch and mineral elements, and the cake after oil extraction also contains about 12% crude protein. However, due to the toxic substance tea saponin (also known as tea saponin) contained in tea seed meal, at present, there is little research on it at home and abroad, and the technology and method of detoxification are not perfect, so that the utilization of tea seed meal is greatly restricted. , except for a small amount of tea saponin extracted from tea seed meal, tea seed meal has basi...

AI Technical Summary

Problems solved by technology

Detoxification by pit-buried fermentation not only requires digging and sealing, but also takes up to half a month to a month; alkaline detoxification requires adding alkaline solution, boiling, filtering, and drying, and alkaline detoxification will also destroy protein; water The extraction method needs to add hot water, keep warm, centrifuge to remove the solution, repeatedly extract and dry; the solvent method needs to grind the tea seeds, add ethanol, and extract with a large amount of water before drying; the existing method is not only cumbersome and time-consuming and less effective
