Abstract

The invention provides low-nitrogen high-energy compound feed for growing Oncorhynchus mykiss and a preparation method thereof. The feed is made from the following components, in percent by weight: 0.1-0.3% of trace element; 0.1-0.15% of vitamins, 0.2-0.4% of choline chloride, 2-3% of calcium dihydrogen phosphate, 0.01-0.02% of astaxanthin, 0.1-0.2% of beta carotene, 15-20% of shrimp meal, 15-25% of fermented soybean meal, 5-10% of fish meal, 3-6% of spray-dried swine blood cells, 1-2% of Spirulina powder, 1-2% of soybean lecithin oil, 5-8% of soybean oil, 4-6% of fish oil, 10-15% of flour, 10-15% of chicken powder, and 5-15% of mixed meal. By adding the spray-dried swine blood cells to replace part of fish meal protein, feed cost is reduced; the feed has high energy and low protein.

Description

technical field [0001] The invention relates to the technical field of fish feed, in particular to a low-nitrogen high-energy rainbow trout growth compound feed and a preparation method thereof. Background technique [0002] Rainbow trout belongs to Salmoniformes and Salmonidae. It is known as "water ginseng". It is a rare and valuable economic fish species in my country. It has a large domestic breeding area and a large amount of feed for rainbow trout. At present, the protein content of the main feed is 42%-45%, and the fat content is 13%-16%. Because the price of animal protein such as fishmeal remains high, the cost of feed is high, which seriously affects the economic benefits of farmers. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a low-nitrogen high-energy rainbow trout growth compound feed and a preparation method thereof, which can save protein and reduce feed cost. [0004] In order to achieve th...
