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 the application and formula of rubber seed oil in compound feed for rainbow trout, belonging to the technical field of aquaculture. Use rubber seed oil to partially replace fish oil and add it to the rainbow trout compound feed. The weight percentages of various raw materials in the compound feed are: fish meal 16-20%, soybean meal 28-32%, cottonseed meal 8-12%, rapeseed meal 13-17% %, corn gluten powder 6-10%, high-gluten flour 1-4%, rubber seed oil 4-12%, fish oil 0-8%, soybean lecithin 0.3-0.5%, calcium dihydrogen phosphate 0.7-1.2%, chlorine Choline 0.1-0.3%, vitamin C phosphate 0.02-0.05%, ethoxyquinoline 0.01-0.03%, mineral premix 0.5-1.0%, vitamin premix 0.5-1.0%; weight of all raw materials The sum of the percentages is 100%. The invention makes full use of rubber seed oil as the fat source in rainbow trout feed, saves fish oil, which is a scarce feed oil, and the compound feed has no adverse effects on rainbow trout. At the same time, it reduces formula cost and feed coefficient, has high cost performance, and improves rainbow trout Breeding benefits.

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...
