specific Embodiment approach 1

[0020] Specific embodiment one: present embodiment is a kind of feed that inhibits triploid rainbow trout intestinal proteus, described feed is by weight 200 parts of secondary meal, 398 parts of fish meal, 290 parts of soybean meal, 60 parts of fish oil, 20 parts of It consists of phospholipid oil, 10 parts of calcium dihydrogen phosphate, 3 parts of vitamin premix, 2 parts of trace element premix, 2 parts of choline chloride, 5-10 parts of xylooligosaccharide and 0-5 parts of cellulose.

specific Embodiment approach 2

[0021] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the feed consists of 200 parts by weight, 398 parts of fish meal, 290 parts of soybean meal, 60 parts of fish oil, 20 parts of phospholipid oil, 10 parts of phosphoric acid Calcium dihydrogen, 3 parts of vitamin premix, 2 parts of trace element premix, 2 parts of choline chloride, 5 parts of xylooligosaccharide and 5 parts of cellulose. Others are the same as the first embodiment.

specific Embodiment approach 3

[0022] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the feed consists of 200 parts by weight, 398 parts of fish meal, 290 parts of soybean meal, 60 parts of fish oil, 20 parts of phospholipid oil, 10 parts by weight. It consists of 1 part of calcium dihydrogen phosphate, 3 parts of vitamin premix, 2 parts of trace element premix, 2 parts of choline chloride, 6 parts of xylooligosaccharide and 4 parts of cellulose.

Abstract

The invention discloses a feed for inhibiting intestinal proteobacteria of triploid rainbow trout, belongs to the technical field of aquatic feeds, and relates to a feed for improving intestinal floraof the triploid rainbow trout. The feed provided by the invention is to solve the technical problem that of the intestinal proteobacterium diseases of the triploid rainbow trout are epidemic with enlargement of a culture scale and reinforcement of a culture density and continuous increase of environmental stress. The feed is composed of the following components in parts by weight: 200 parts of wheat middling, 398 parts of fish meal, 290 parts of soybean meal, 60 parts of fish oil, 20 parts of phospholipid oil, 10 parts of monocalcium phosphate, 3 parts of a vitamin premix, 2 parts of a traceelement premix, 2 parts of choline chloride, 5-10 parts of xylooligosaccharide and 0-5 parts of cellulose. The method provided by the invention has the advantages of simple and scientific steps, reasonable formula and the like. The feed disclosed by the invention can inhibit the intestinal proteobacteria of the triploid rainbow trout, so intestinal health is improved, and rapid growth is promoted.According to the feed disclosed by the invention, in breeding practice, the feed coefficient is reduced by 0.08, and the growth speed is increased by 0.7%-9%.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed and relates to a feed for improving intestinal flora of triploid rainbow trout. Background technique [0002] Triploid rainbow trout (Oncorhynchus mykiss) grows faster than ordinary rainbow trout, is larger in size, stronger in disease resistance, bright in color, tender in meat quality, and high in economic value. It is one of the world's high-quality aquaculture species and is suitable for breeding in areas with cold water resources. [0003] Although the current domestic rainbow trout feed can meet the daily nutritional needs of rainbow trout, due to the lack of basic research on the nutrition and feed of triploid rainbow trout, the production potential of triploid rainbow trout has not been fully utilized, and the price of feed is still high , It is necessary to further study the nutritional physiology and feed formula of triploid rainbow trout, develop a full range of high-quality and lo...
