Tilapia mossambica formula feed with rubber seedcakes and soya bean meal serving as main protein raw materials

Abstract

The invention relates to a tilapia mossambica formula feed with rubber seedcakes and soya bean meal serving as main protein raw materials, and belongs to the technical field of aquaculture. The tilapia mossambica formula feed comprises the following raw materials in percentage by weight: 4 to 8% of fish meal, 10 to 40% of rubber seedcakes, 34 to 40% of soya bean meal, 8 to 12% of wheat middling, 10 to 14% of rice husk,1 to 2% of soybean oil, 0.5 to 1.0% of soya bean lecithin, 0.7 to 1.0% of monocalcium phosphate, 0.03 to 0.05% of vitamin C phosphate ester, 0.1 to 0.2% of choline chloride, 0.1 to 0.3% of methionine, 0.1 to 0.2% of lysine, 0.01 to 0.03% of ethoxyquin, 0.5 to 0.8% of mineral substance premix, and 0.5 to 0.8% of vitamin premix; and the sum of all raw materials in percentage by weight is 100%. According to the tilapia mossambica formula feed, the rubber seedcakes are fully used as the protein raw material of the tilapia mossambica formula feed, so that the soya bean meal and other scarce protein sources can be saved; and the feed has no obvious harmful effect on tilapia mossambica; and meanwhile, the formula cost and feed coefficient are reduced and the culture benefits of the tilapia mossambica are increased.

Description

technical field [0001] The invention relates to a tilapia compound feed, in particular to a tilapia compound feed with rubber seed cake and soybean meal as main protein raw materials, belonging to the technical field of aquaculture. Background technique [0002] Tilapia, commonly known as African crucian carp, is mostly plant-based omnivorous fish. Tilapia not only has the advantages of fast growth, strong disease resistance, wide feeding habits, and short breeding cycle, but also has high meat content and no intermuscular spines, so it is often used as the main raw material for fish fillet processing. Tilapia is an excellent fish species recommended by the Food and Agriculture Organization of the United Nations (FAO). It is listed by FAO as the six major staple foods, and its farming range covers 85 countries and regions. Since the 1990s, my country's tilapia aquaculture industry has developed rapidly. In 2012, the total output of tilapia reached 1.441 million tons, rankin...

Problems solved by technology

[0006] In the prior art, patent CN101194669A relates to the process of using rubber seed cake (meal) to produce protein feed, but does not involve the ratio and efficacy of rubber seed cake (meal) replacing other protein raw materials; patent CN101473889A involves the use of rubber seed kernels to prepare protein feed The formula and method of raw materials, but it mainly uses rubber seeds to prepare protein feed raw materials, rather than directly using rubber seeds as protein feed

In view of the obvious differences in the tolerance and utilization efficiency of anti-nutritional factors contained in rubber seed cakes of different species of animals, the dosage given in the existing formula as a protein feed raw material to prepare aquatic feed is extremely unreasonable and cannot meet the needs of aquaculture
