Tea ground fermentation feed additive for fattening ducks and preparation method of tea ground fermentation feed additive

Abstract

The invention discloses a tea ground fermentation feed additive for fattening ducks. The tea ground fermentation feed additive is prepared from the following raw materials in parts by weight of 455-495 parts of tea grounds, 30-70 parts of loaches, 30-70 parts of earthworms, 55-95 parts of edible mushroom dregs, 100-130 parts of shrimp shells, 125-165 parts of herba hedyrotidis diffusae, 125-165 parts of sandwort, 125-165 parts of goose grass, 45-75 parts of radix aconiti ecalcarati, 150-200 parts of gnaphalium affine, 150-200 parts of Chinese cabbages, 150-200 parts of Ixerischinensis, 150-200parts of sweet potato leaves, 235-275 parts of corn, 120-160 parts of rice bran meal and 25-55 parts of microbial fermentation microbial inoculum. According to the tea ground fermentation feed additive, waste is turned into wealth, so that the utilization rate of sources is increased, and the production cost of the feed additive can also be reduced; and tea polyphenols in the tea grounds enter the bodies of the fattening ducks, so that the beneficial bacteria of lactobacilli and the like in bodies of the ducks can be obviously increased, and the disease resistance and the duck meat quality ofthe fattening ducks can be improved.

Description

technical field [0001] The invention belongs to the technical field of feed additive production, in particular to a feed additive for fattening ducks fermented with tea dregs and a preparation method thereof. Background technique [0002] China is a country with a large population and a large breeding industry. With the development of the breeding industry, the feed industry is also developing rapidly. Every year, my country's feed industry consumes a lot of feed materials such as energy feed, protein feed, vitamin feed and mineral feed. This means that a considerable part of planting and breeding resources is occupied, and with the increase in the price of agricultural and sideline products, the cost of the feed industry is also getting higher and higher. [0003] my country is a big tea-producing country with a long history of tea processing. The annual tea output has reached more than 2 million tons, but the primary products are the main products, and the deep processing a...

Problems solved by technology

However, raw materials such as chemical spices, growth-promoting agents, and disease-preventing antibiotics are added to the raw materials for this patent application, which will reduce the palatability of the feed, poor taste, and can not cause great appetite for ducks. The feed utilization rate is low, and duck fattening cannot be accelerated. High, and the raw materials will remain in the duck meat, long-term consumption will affect human health
