Processing method for black carp buoyancy expanding compound feed

Abstract

The invention discloses a processing method for black carp buoyancy expanding compound feed, which sequentially comprises steps of coarse grinding of a large amount of raw materials, mixing uniformity of first raw material, ultramicro grinding, mixing uniformity of second raw material, hardening and tempering, drying, cooling and the like. The black carp buoyancy expanding compound feed is simple to make up and easy to manage, has overall and balanced nutrition, high digestibility, good disease prevention, excellent water stability, few feed waste and water pollution. By the products of the invention, coefficients of bait are low, the growth speed of the black carp is fast, and the cultivation period is short.

Description

【Technical field】

[0001] The invention relates to the field of fish compound feed and its processing, in particular to a method for processing herring buoyant puffed compound feed. 【Background technique】

[0002] Herring, also known as snail green, green carp, black carp, green root fish, etc., belongs to Cyprinidae and Yaluo subfamily of Cyprinidae. Herring is one of the four traditionally farmed fish in my country. It has the characteristics of fast growth, high yield and delicious meat, and is a popular breeding object. At present, herring farming has spread all over most of China, and it is one of the main species of freshwater aquaculture in my country. Herring has a high demand for feed nutrition, and the quality of feed has a direct impact on the growth of herring. Someone has carried out research on the nutritional requirements and feed formula (for example: Chinese patent CN1692796A) at the growth of herring. At present, in the process of herring breeding, farmer...
