Abstract

The invention discloses a preparation method for puffed feed for snakeheads. The preparation method comprises the following steps: weighing ingredients according to the formula, mixing the weighed ingredients, crushing the mixed ingredients, and sieving the crushed ingredients 2-3 times according to the needs until the mixed ingredients can pass through a 100-mesh sieve; transferring raw material powder into a modulator, and introducing steam which accounts for 16-18% of raw material powder in mass to modulate; then, introducing the modulated raw material powder into an extruding, puffing and granulating machine for preparing feed granules; and drying the feed granules so as to obtain the finished product of the puffed feed. The puffed feed for snakeheads provided by the invention has excellent index performance, the feed coefficient is low, and snakeheads fed by the feed are healthy, better in constitutional health, and extremely high in survival rate. In addition, the snakehead fed with the puffed feed does not have hepatic pathological changes, and thus, the feed disclosed by the invention has an extremely good liver protecting effect.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to an extruded feed for snakeheads and a preparation method thereof. Background technique [0002] Snakehead (Ophiocephalus argus), also known as black fish, has strong environmental adaptability and is widely distributed in the north and south waters of my country. It is one of the common ferocious carnivorous fish in China. The meat of the snakehead is delicious, nutritious, high in protein and low in fat, and has no intermuscular spines. It is a rare fish with high economic value; moreover, the snakehead also has the functions of removing addiction, promoting muscle and blood, nourishing and recuperating, diuretic and expelling wind, It has food tonic and medicinal effects such as promoting wound healing, so it is deeply loved by the people. In recent years, the market demand for snakeheads has been increasing. [0003] The existing snakehead culture technology is to feed chilled fresh...
