Embodiment 1

[0021] Taking the production of 1# large yellow croaker compound feed as an example, the content of each component in 100kg of raw materials (unit: kg): fish meal 45, brewer’s yeast 2, corn gluten meal 4, shrimp shell powder 3, squid offal powder 2, soybean meal 12, rice bran 4 , flour 22, calcium dihydrogen phosphate 1, fish oil 3, large yellow croaker premix 2.

[0022] Mix other raw materials except flour, fish oil and large yellow croaker premix until the coefficient of variation of mixing uniformity C.V. , 1kg fish oil and large yellow croaker premix are mixed again until the coefficient of variation C.V.<7.5% of the mixing uniformity; The moisture content is 23-24%. The material after conditioning is extruded through an extrusion extruder with a flat die of 1.5mm. The expansion coefficient of the feed pellets is controlled to be 1.5-1.6. The extruded material is dried and the drying temperature is controlled. At 100-110°C, control the drying time so that the moisture co...

Embodiment 2

[0024] Take the production of 4# large yellow croaker compound feed as an example, the content of each component in 100kg of raw materials (unit: kg): fish meal 40, brewer’s yeast 2, corn gluten meal 5, shrimp shell powder 3, squid offal powder 2, soybean meal 14, rice bran 4, Flour 23, fish oil 4, calcium dihydrogen phosphate 1, large yellow croaker premix 2.

[0025] Mix other raw materials except flour, fish oil and large yellow croaker premix until the coefficient of variation of mixing uniformity C.V. , 1kg fish oil and large yellow croaker premix are mixed again until the coefficient of variation C.V.<7.5% of the mixing uniformity; The moisture content is 23-24%. After conditioning, the material is extruded through an extrusion extruder with a flat die of 3.5mm. The expansion coefficient of the feed pellets is controlled to be 1.6-1.7. The extruded material is dried, and the drying temperature is controlled. At 100-110°C, control the drying time so that the moisture con...

Embodiment 3

[0027] Take the production of 6# large yellow croaker compound feed as an example, the content of each component in 100kg of raw materials (unit kg): fish meal 37, brewer’s yeast 2, corn gluten meal 4, shrimp shell powder 3, squid viscera powder 2, soybean meal 16, rice bran 5, Flour 23, fish oil 5, calcium dihydrogen phosphate 1, large yellow croaker premix 2.

[0028] Mix other raw materials except flour, fish oil and large yellow croaker premix until the coefficient of variation of mixing uniformity C.V. , 1.5kg fish oil and large yellow croaker premix are mixed again until the coefficient of variation C.V.<7.5% of mixing uniformity; The moisture content of the raw material is 23-24%, and the material after conditioning is extruded through an extrusion extruder with a flat die of 5.7mm. The expansion coefficient of the feed pellets is controlled to be 1.7-1.8, and the extruded material is dried. Control the drying time at 105-115°C so that the moisture content of the feed ...

Abstract

The invention relates to an environment-friendly highly-efficient large yellow croaker compound feed. The feed is characterized in that the feed comprises the following compositions by weight percentage: 35 to 45 percent of fishmeal, 2 percent of beer yeast, 3 to 5 percent of maize protein meal, 2 to 4 percent of shrimp shell meal, 2 percent of sleeve-fish visceral meal, 12 to 18 percent of soybean meal, 3 to 5 percent of rice bran, 22 to 26 percent of flour, 3 to 5 percent fish oil, 1 percent of calcium dihydrogen phosphate and 2 percent of large yellow croaker premix. The large yellow croaker compound feed can meet the nutritional requirement of the growth of large yellow croaker in each stage, has low lost and bait coefficient of less than 1.5 and reduces the contents of ammonia nitrogen and nitrite in a breeding water area; and the performance of the compound feed reaches the standard requirement of breeding water quality and is suitable for the current high-density breeding mode.

Description

Technical field: [0001] The invention belongs to the field of aquatic feed, in particular to an environment-friendly high-efficiency large yellow croaker compound feed. Background technique: [0002] In recent years, 290,000 boxes of large yellow croakers are cultured in net cages in our province every year, and the annual aquaculture output is about 55,000 tons. fish, which greatly increases the pollution of the waters in the breeding sea area. In August 2007, according to relevant departments, the contents of ammonia nitrogen and nitrite in the water of Ningde Sanduao sea area were 0.5-0.6mg / L and 0.10-0.11mg / L respectively, resulting in a large number of large yellow croaker cultured in cages in this sea area dying. rate of more than 50%. At present, a small number of feed manufacturers have produced compound feeds for large yellow croakers, but due to insufficient research on the living habits and nutritional requirements of large yellow croakers, large yellow croakers...
