Problems solved by technology

At present, in the process of herring breeding, farmers mainly use hard pellet feed pressed by ordinary granulators, but the stability of hard pellet feed is poor, the rate of loss in water is very high, the waste of feed is large, and it seriously pollutes the breeding water. It is not suitable for high density and Large-scale herring farming

Embodiment 1

[0022] 1. According to the nutritional formula of herring, coarsely pulverize the required bulk raw materials such as fish meal, soybean meal, dephenolized cottonseed protein, cotton meal, rapeseed meal, DDGS, wheat, and corn through a hammer mill. Among them, DDGS (Distillers Dried Grains with Solubles) is a high-protein feed formed after microbial fermentation, distillation, evaporation, and drying in the process of producing ethanol from corn. This feed is not only rich in protein, but also rich in Amino acids, vitamins and a variety of minerals that are beneficial to animal growth, do not contain anti-nutritional factors, contain a lot of vitamins and minerals, can promote livestock production and enhance immunity. Suitable for feeding poultry, livestock, dairy cows, aquatic products and various animals.

[0023] 2. The mass percentage is 15% fish meal, 15% soybean meal, 11% dephenolized cottonseed protein, 8% cotton meal, 8% rapeseed meal, 3% blood meal, 6% DDGS, 16% Sec...

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...
