Simulated ecological pelteobagrus flvidraco puffed compound feed

Abstract

The present invention discloses a simulated ecological pelteobagrus flvidraco puffed compound feed. The pelteobagrus flvidraco puffed compound feed is prepared from a powdered feed by mixing, puffingand granulating. The powdered feed consists of the following components in mass percentages: 25%-45% of fish steak powder, 12%-25% of rice bran, 10%-15% of threonine microbial proteins, 15%-20% of flour, 3%-5% of beer yeasts, 1%-3% of calcium dihydrogen phosphate, 1%-2% of minerals, 0.3%-0.8% of betaine, 0.2%-0.5% of choline chloride, 0.3%-0.5% of edible salt, 0.2%-0.5% of curcumin and 0.1%-0.3% of multi-vitamins for fish. Compared with conventional pelteobagrus flvidraco compound feeds, the puffed compound feed has the following advantages: 1, the cost is low; and the fish steak powder is only used to replace fish powder and the feed cost can be reduced by 1,250 yuan to 2,250 yuan / ton; 2, the mortality rate is reduced by 50% or more; and the incidence rate is reduced by 60%-80%; 3, the food intake is increased by 15%-20%; and the feed efficiency is increased by 10% or more; and 4, the body color of the cultured pelteobagrus flvidraco is close to the body color of the wild pelteobagrusflvidraco.

Description

technical field [0001] The invention relates to an aquatic compound feed, in particular to an ecologically imitated puffed catfish puffed compound feed, which belongs to the field of aquatic feed. Background technique [0002] Yellow catfish (Pelteobagrus flvidraco) belongs to the family Siluriformes, Paliidae, and the genus Pelteobagrus. It has nourishing effect and medicinal value. Yellow catfish is widely distributed in waters such as rivers, lakes, reservoirs, ditches, and ponds in my country. It is a bottom-dwelling omnivorous carnivorous freshwater fish with high economic value. In recent years, yellow catfish has been cultured on a large scale in my country's coastal and inland areas. According to the data in the 2017 China Fishery Statistical Yearbook, the annual output of yellow catfish in 2016 was 417,300 tons. Based on the current development situation, the future is estimated In the next few years, the aquaculture area and production of yellow catfish will still...
