Low-fish-meal-content feed for salmon

Abstract

The invention relates to low-fish-meal-content feed for a salmon, and belongs to the technical field of a feed. The feed is manufactured from the following raw materials, according to a weight part ratio, 2-5 parts of fish meal, 25-40 parts of a raw vegetable protein material, 35-60 parts of a raw animal protein material, 0.4-1 part of a mineral feed, 0.7-1.2 parts of a vitamin premix feed, 8-15 parts of green feed, and 3-8 parts of a health-care reinforcement material. In the low-fish-meal-content feed, vegetable protein and animal protein are selected as the raw protein materials to reduce dependence of the salmon on fish meal. Palatability of the feed is not affected, and the mineral feed and the vitamin premix feed are added for further improving nutritional ingredients of the feed and absorption efficiency by the salmon. The health-care reinforcement material is added for further improving disease resistance and immunity of the salmon, thereby reducing cost of the salmon in an artificial feeding environment and increasing the benefit.

Description

technical field [0001] The invention relates to a low-fish meal feed for salmon, which belongs to the technical field of feed. Background technique [0002] Salmon is a highly migratory fish in cold water. Salmon meat is delicious and has a good taste. Its meat color is auspicious red or bright orange, which can easily arouse people's appetite and can enhance the reunion atmosphere of the banquet. It is rich in nutrition and has many benefits for human health. Therefore there have been more and more salmon breeding bases, especially salmon breeding bases have been built in my country's Heilongjiang and the upper reaches of the Yellow River in Qinghai. However, due to the high difficulty of raising salmon, the requirements for its feed are relatively high, especially the requirements for protein raw materials in the feed. At present, fish meal is the main protein raw material, but due to the increase of fish farming, the demand for fish meal is high. The demand is increasin...

Problems solved by technology

However, due to the high difficulty of raising salmon, the requirements for its feed are relatively high, especially the requirements for protein raw materials in the feed. At present, fish meal is the main protein raw material, but due to the increase of fish farming, the requirement of fish meal The demand is increasing and the price is rising steadily, which leads to the rising price of fish feed, which will easily lead to a substantial increase in the cost of raising salmon, thus causing difficulties for artificial breeding
