Embodiment

[0015] Fish meal, soybean meal, cottonseed meal, rapeseed meal and rubber seed cake were used as feed protein sources, soybean oil and soybean lecithin were used as fat sources, and five kinds of isonitrogen and isoenergy feeds were prepared according to the conventional feed formula (as shown in Table 1 ). Wherein, no yucca extract was added to the feed of Example 1, which was used as a control group; the amount of yucca extract added to the feeds of Examples 2-5 was 75-600 mg / kg feed.

Abstract

The invention relates to an application of yucca in a compound feed for megalobrama amblycephala and a formula of the feed, belonging to the technical field of aquaculture. A yucca extract is added in the compound feed for the megalobrama amblycephala and the compound feed comprises the following raw materials by weight percent: 3-6% of fish meal, 7-12% of soybean meal, 16-20% of cotton seed meal, 16-20% of rapeseed meal, 12-15% of rubber seed cake, 8-12% of wheat bran, 10-15% of rice bran, 2-4% of soybean oil, 0.3-0.5% of soybean lecithin, 0.015-0.06% of yucca extract, 1.0-1.8% of monocalcium phosphate, 0.05-0.1% of vitamin C phosphate ester, 0.1-0.2% of choline chloride, 0.01-0.03% of ethoxy quinoline, 2-3% of zeolite powder, 0.2-0.4% of table salt, 1-3% of bentonite, 0.5-1.0% of mineral substance premixture and 0.5-1.0% of vitamin premixture. Using amount of medicines such as antibiotics are reduced, the quality safety of aquatic products is guaranteed, the anti-stress capability and the disease resistance capability of the megalobrama amblycephala are enhanced, the growth of the megalobrama amblycephala is promoted and therefore, the culturing benefit of the megalobrama amblycephala is increased.

Description

technical field [0001] The invention relates to a compound feed for bream, in particular to the application and formula of yucca in the compound feed for bream, and belongs to the technical field of aquaculture. Background technique [0002] Megalobrama amblycephala (Megalobrama amblycephala) belongs to Cyprinidae, Cyprinidae, Cyprinidae, and Genus Brama, and is commonly known as Wuchang fish, Megalobrama amblycephala, flat-breasted bream, etc. The bream is native to some lakes in the middle and lower reaches of the Yangtze River in my country, and is a herbivorous economic fish. Under natural conditions, juvenile fish mainly feed on cladocera and crustaceans, while adult fish eat aquatic plants, mainly bitter grass and hydrilla, and a small amount of zooplankton; under artificial breeding, bream can eat granular compound feed . Because of its fast growth, strong adaptability, wide feeding habits, short feeding cycle, high meat content, tender and delicious meat, and rich ...
