Perch feed formula and preparation method thereof

Abstract

The invention discloses a perch feed formula and a preparation method thereof, and relates to the technical field of fish farming. In the perch feed formula, imported white fish meal, spray-dried blood globulin powder and antarctic krill powder and other high-quality protein raw materials are added, so that the digestion and absorption rate of perch is high, the growth rate is improved, and the protein needs are met; vitamins, probiotic, and broken yeast powder are comprehensively complemented to enhance the body constitution of perch, improve immunity, promote digestion and absorption and reduce the occurrence of enteritis; the feed formula is treated by an expansion process to effectively improve the absorption and utilization rate of a feed, an expander used is simple in structure and convenient to use, and has high expansion efficiency, and a communicating pipe of the expander can be effectively prevented from being clogged by the feed; the preparation process of the feed formula has the advantages of reducing the damage to the nutrient composition of the feed, ensuring the particle size and mixing uniformity of the feed, increasing the energy level in the feed, and having obvious economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a feed formula for perch and a preparation method thereof. Background technique [0002] Perch is favored by breeders because of its rapid growth, delicious taste and high economic benefits. Perch farming develops rapidly and is the main species of marine culture in my country. [0003] In the process of sea bass culture in sea cages, chilled fish is often used as bait. The source of fresh and live fish is limited, and the catch is greatly affected by the season, so it is not easy to preserve. Fresh and live fish that have not been eaten sink to the bottom of the water, resulting in eutrophication of the water body. It causes great damage to the fragile water environment, and perch is prone to serious parasitic diseases; on the other hand, the amount of fresh fish feed is large, the cost is high, and some fish suffer from vitamin deficiency. In response to these...

Chemical drugs such as antibiotics do have a good therapeutic effect on certain diseases, but they have no effect on diseases caused by viruses. Excessive use or even abuse will increase the drug resistance of pathogens that treat diseases, and eventually lead to the failure of antibiotics

Adopting high-quality feed is the guarantee for producing high-quality perch products, but the content of protein and vitamins in the existing perch feed is low, easy to deteriorate, and cannot meet the nutritional needs of perch, resulting in slow growth of perch, small size, light weight, and easy to feed. disease, vitamin deficiency
