Embodiment

[0015] Using fishmeal, soybean meal, cottonseed meal, rapeseed meal and corn gluten meal as feed protein sources, rubber seed oil, fish oil and soybean lecithin as fat sources, according to the conventional feed ratio scheme, four kinds of isonitrogen and isoenergy feeds were formulated ( As shown in Table 1), wherein, rubber seed oil is not added in the feed of Example 1, as a control group; the amount of rubber seed oil added in the feed of Examples 2-4 is 4-12% to replace fish oil.

Abstract

The invention relates to application of rubber seed oil to rainbow trout compound feed and a formula of the rubber seed oil, and belongs to the technical field of aquaculture. The rubber seed oil is substituted for fish oil partially to be added into the rainbow trout compound feed. The compound feed comprises, by weight, 16-20% of fish meal, 28-32% of bean pulp, 8-12% of cottonseed meal, 13-17% of rapeseed dregs, 6-10% of corn gluten meal, 1-4% of high gluten flour, 4-12% of the rubber seed oil, 0-8% of the fish oil, 0.3-0.5% of soya bean lecithin, 0.7-1.2% of monocalcium phosphate, 0.1-0.3% of choline chloride, 0.02-0.05% of vitamin C phosphate, 0.01-0.03% of ethoxyquin, 0.5-1.0% of mineral substance premix and 0.5-1.0% of vitamin premix. The sum of weight percentages of all raw materials is 100%. The application of the rubber seed oil to the rainbow trout compound feed and the formula of the rubber seed oil have the advantages that the rubber seed oil is fully utilized to serve as a fat source in the rainbow trout compound feed, the fish oil as feed grease in short supply is saved, and the compound feed has no bad influence on rainbow trout; formula cost and feed factors are reduced, high cost performance is achieved, and culture benefit of the rainbow trout is improved.

Description

technical field [0001] The invention relates to a compound feed for rainbow trout, in particular to the application and formula of rubber seed oil in the compound feed for rainbow trout, and belongs to the technical field of aquaculture. Background technique [0002] Fish oil is an excellent fat source for aquafeeds. At present, the global fish oil production remains relatively stable, while the demand for fish oil in the aquafeed industry is constantly increasing. In 2010, the proportion of global fish oil used in aquafeed reached 88%. In recent years, the rapid development of the aquaculture industry has led to a sharp increase in the consumption of fish oil, and the high price of fish oil has caused tremendous pressure on aquafeed companies and the aquaculture industry. Due to the limited resources and excessive consumption of fish oil, as well as the possible accumulation of dioxins and polychlorinated biphenyls in fish oil and their price, the aquaculture industry urg...
