Abstract

The invention discloses a feed additive containing a shrimp processing by-product namely protein powder. The feed additive is prepared from the following components in parts by weight: 5-10 parts of the shrimp processing by-product namely the protein powder, 0.5-1 part of a rosemary extract, 1-3 parts of carvacrol and 30-40 parts of feed level zeolite powder. The feed additive containing the shrimp processing by-product namely protein powder disclosed by the invention is simple in components, good in preservability and dispersibility, wide in application range, low in cost and extremely suitable for popularization and application in feeds. The invention further discloses a preparation method of the feed additive containing the shrimp processing by-product namely protein powder. The preparation method comprises the following steps of (I), preparing the shrimp processing by-product namely the protein powder; and (II) performing compounding. The preparation method disclosed by the invention is simple in technological steps, stable and controllable in process, energy-saving, efficient and environmentally-friendly, the environment pollution caused by the shrimp processing by-product can be reduced, actual basis is provided for enterprises to realize the resource utilization of the shrimp processing by-product, and the further increase of the economic value of shrimps is facilitated.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive containing shrimp processing by-product protein powder and its preparation method and application. Background technique [0002] At the same time, my country's feed industry is developing rapidly, and feed resources, especially protein resources, are in short supply. The development of new protein feeds has become a top priority. At present, the protein sources in the feed are mainly various fish meal and shrimp meal, etc., which are costly and are added in an extensive way, that is, the fish meal and shrimp are directly crushed and mixed into the feed, which is not conducive to the digestion and absorption of animals. Low, especially for all kinds of cubs and seedlings, whose digestive system is immature and their digestion ability is weak, and eating a large amount may even cause diarrhea and other phenomena. [0003] my country is rich in shrimp production, and the processed...
