Regulator for improving intestine health of juvenile fish of micropterus salmoides at feed change stage and preparation method and application of regulator

Abstract

The invention provides a regulator for improving intestine health of juvenile fish of micropterus salmoides at a feed change stage and a preparation method and application of the regulator and belongsto the technical field of feed additives. The regulator comprises 5-30% of tea polyphenol, 5-20% of oxidized konjac glucomannan, 20-50% of linseed oil, 10-30% of inulin and 25-40% of a carrier. The preparation method specifically comprises the following steps: putting the linseed oil into a stainless steel reaction kettle, slowly adding the carrier, performing uniform stirring so as to obtain a linseed oil mixture, screening the linseed oil mixture by using an 80-100-mesh sieve, respectively adding the tea polyphenol, the oxidized konjac glucomannan and the inulin, performing uniform mixing and stirring, inspecting contents of components of the obtained mixture, and performing bottling and packaging. The obtained regulator is used in preparation of feeds for the juvenile fish of the micropterus salmoides at the feed change stage, intestine health of the juvenile fish of the micropterus salmoides at the feed change stage can be greatly improved, intestinal diseases can be reduced, anduse of antibiotics in the breeding process can be reduced.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a regulator for improving the intestinal health of juvenile California perch during feeding. Background technique [0002] The scientific name of California perch is largemouth bass. It is native to the Mississippi River system in North America. It has strong disease resistance, fast growth, easy to catch, wide temperature range, beautiful appearance, no intermuscular spines, and tender meat. With its unique quality and growth advantages, California sea bass has always been favored by consumers. As an exotic fish species, California perch has taken root in China after decades of development. Judging from the domestic market supply and demand, it has now risen from a cultivar to a suitable species. In recent years, with the breakthrough of the whole pellet feed and feeding technology, California sea bass has become a "hot breeding star". A breakthrough has bee...
