Feedstuff additive capable of improving body color of aquatic animal

Abstract

The invention relates to the technical field of aquaculture feedstuff, in particular to feedstuff additive premix material. The feedstuff additive comprises the following components according to the following weight portion: 150 to 450 portions of astaxanthin, 300 to 700 portions of dunaliella sallina, 150 to 400 portions of vitamin E, 300 to 600 portions of Chinese thorowax, 100 to 250 portions of canthaxanthin, 300 to 600 portions of antioxidant, and 150 to 1,000 portions of corn protein powder. The feedstuff additive has no innocuous and side residue, no drug resistance, environmental protection, and no adverse effect on the feedstuff palatability. The feedstuff additive can obviously improve the body color of fishes in the yellow and red color systems such as golden pompano, pseudobagrus fulvidraco, clarias fuscus, sea bream, large yellow croaker, and the like, can make the body color display natural yellow or red color, and can effectively improve the immunity, reproductive capacity and meat quality of cultivated fish. In addition, the feedstuff additive has stable raw material sources and a simple manufacturing process.

Description

【Technical field】 [0001] The invention relates to the technical field of aquaculture feed, in particular to a feed additive premix. 【Background technique】 [0002] With the continuous improvement of people's living standards, people's requirements for the quality of aquatic products they consume are increasing day by day. The fish and shrimps grown in the natural state are bright in color and delicious in meat quality, but under the conditions of artificial intensive farming, due to the extensive use of artificial compound feed, the breeding cycle of fish, shrimp, and crabs is shortened, and only a small amount of natural aquatic organisms can be obtained. There are few effective color sources and unstable ingredients in the feed, which will lead to the lightening of the body color of fish, shrimp and crab, which will inevitably affect the price of the commodity. Therefore, how to improve the body color of farmed aquatic animals to be close to that of wild fish and shrimp h...
