Abstract

The invention discloses puffed floating compound feed for black carp. The puffed floating compound feed for the black carp consists of the following raw material components in percentage by mass: 13 to 18 percent of fish meal, 17 to 23 percent of bean pulp, 5 to 10 percent of peanut meal, 18 to 25 percent of rapeseed meal, 3 to 8 percent of rice bran, 20 to 25 percent of high-gluten flour, 1 to 5 percent of monocalcium phosphate, 1 to 3 percent of special premix for the black carp, 1 to 3 percent of fish oil and 0.5 to 2 percent of soyabean lecithin. The invention also provides a preparation method of the puffed floating compound feed for the black carp. The puffed floating compound feed for the black carp has scientific and reasonable nutritional ingredient proportion and can meet normal growth of the black carp, and the survival rate reaches above 95 percent; the raw materials are subjected superfine grinding and then are subjected to high-temperature tempering, extrusion pelleting and puffling modeling to form the feed, the ageing degree reaches above 95 percent, the ingestion and absorption utilization ratio of the black carp is high, the feed coefficient is low, excrements and diseases are few, and pollution to the water quality is greatly reduced, so that the medicine using cost is reduced and the survival rate and the growth speed of the black carp are increased.

Description

technical field [0001] The invention belongs to the field of fish compound feed, and in particular relates to a buoyant puffed compound feed for herring and a preparation method thereof. Background technique [0002] The rise of fish farming in my country began in the 1990s. At the beginning, wheat, rapeseed, cakes and other single feeds were used for breeding. The pollution was serious, the breeding cycle was long, and the efficiency was poor. Fish could not be marketed within a year. Later, it was developed to use a variety of grain by-products to prepare and press them into hard pellets for feeding. The waste was reduced, the cycle was shortened, and the benefit was improved. However, due to the failure of the feed to be ingested to the maximum extent, the waste of the feed and the pollution of the breeding waters are caused. [0003] Herring, also known as "green salamander" and "snail green", has a large body, beautiful fish shape, fresh and tender meat, and high nutri...
