Embodiment 1

[0014] Embodiment 1: Preparation of tilapia extruded feed 1

[0015] A. Weigh 10kg of direct fire fish meal, 20kg of soybean meal, 10kg of meat and bone meal, 22kg of rapeseed meal, 8kg of malt root, 1kg of liquid phospholipid, 5kg of secondary meal, 20kg of corn, 1kg of calcium hydrogen phosphate, and compound premix (commercially available) 2kg, fish oil 1kg;

[0016] B. After mixing evenly, pulverize through a superfine pulverizer so that all ingredients can pass through a 20-mesh sieve;

[0017] C. The pulverized material is fed into the modem with 13kg of water vapor at 90°C for 7 minutes, and then the raw material is granulated at a temperature of 98°C into the extrusion granulator;

[0018] D. Dry the extruded feed pellets at 100°C.

Abstract

Disclosed is a puffed feed for Tilapia and process for preparation, wherein the constituents include (by weight percent) fish flour 8-12%, soybean 20-30%, meat and bones meal 0-10%, rapeseed waste 20-30%, malt 5-10%, liquid phosphatide 0.5-1%, short flour 3-5%, maize 15-30%, calcium hydrogen phosphate 0.5-1%, composite premixed material 1-2%, soybean oil 0-0.5%, fish oil 0.5-1%.

Description

【Technical field】 [0001] The invention belongs to the field of fish feed and a preparation method thereof, and in particular relates to a formula and a preparation method of tilapia buoyant puffed feed. 【Background technique】 [0002] Tilapia belongs to Perciformes and Cichlidae. It is our general term for commonly farmed Nile tilapia, Oni tilapia, Mozambique tilapia, etc. Tilapia has the advantages of wide appetite, low oxygen tolerance, fast growth, less disease, strong reproductive ability, etc., and has been identified as "promising farmed fish" by the International Food and Agriculture Organization (FAO). Since it was introduced into my country in 1981, tilapia farming has spread all over the country and has become one of the main targets of freshwater aquaculture in my country. The quality of feed is one of the key technologies for the development of tilapia aquaculture. For the nutritional requirements of tilapia, someone has designed the rapid cultivation of tilapi...
