Abstract

The invention provides a feed for improving the body color of cyprinus carpio. Tenebrio molitor is used for replacing soybean meal in daily ration of cyprinus carpio, the replacement rate is 45%-100%, and the replacement conversion mode is based on the protein content ratio that the ratio of the protein content of the tenebrio molitor to the protein of the soybean meal is 1.437, that is, the protein of 3.34 g of the tenebrio molitor is equal to the protein of 4.8 g of the soybean meal. According to the feed for improving the body color of the mirror-like carps as well as the preparation method and the application of the feed, the body color of the mirror-like carps can be greatly improved, and meanwhile the problems that the mirror-like carps fed with commodity daily ration are poor in growth performance, nutritional value and quality and the like can be solved.

Description

technical field [0001] The invention relates to the field of fish feeds, relates to the use of special raw materials and the preparation of special feeds, and in particular relates to a feed for improving the body color of the carp with scaly mirrors. Background technique [0002] Carp (Cyprinus carpio) is the most widely farmed freshwater fish species in Asia, with a global production of 2,885,284 tons in 2019. Frame-scale mirror carp, referred to as frame carp, is a kind of common carp. Because of its fast growth rate, strong disease resistance, high feed conversion rate, and almost no scales on its body surface, it occupies an increasing proportion in aquaculture. big. The carp is an omnivorous fish, and the main protein source in its feed is soybean meal. [0003] Due to the increasing shortage of fishmeal resources and the rising price of soybean meal, alternative protein sources have been attracting attention. However, high levels of alternative protein sources in d...
