Problems solved by technology

[0003] At present, fresh miscellaneous fish are still the main source of bait for grouper farming, but the nutrition of fresh miscellaneous fish is unbalanced, the utilization rate is low, it is easy to cause water pollution, and it is easy to bring pathogenic bacteria, which leads to the prevalence of grouper diseases and mortality raised
Grouper pellet compound feed has been developed in the market, but it has not been popularized and used on a large scale due to reasons such as nutritional level and process technology.

Embodiment 1

[0023] Steam dried fish meal 60% pregelatinized starch 20% flour 0% Fermented soybean meal 10% High quality imported fish oil 2% beer yeast 4% minerals 1.8% Calcium dihydrogen phosphate 1% Choline chloride 0.3% multidimensional 0.2% Encapsulated Vitamin C 0.1% Antioxidants 0.02% probiotics 0.28% food attractant 0.3%

[0024] The feed was formulated according to the formula shown in the table above, and the grouper was raised for 60 days. The grouper fed the feed of this example is active, the feed has good viscoelasticity, good water stability, the grouper grows fast, the feed coefficient is 1.21, and the economic benefit is good.

Embodiment 2

[0026] Steam dried fish meal 63% pregelatinized starch 17% flour 5% Fermented soybean meal 7% High quality imported fish oil 1% beer yeast 3.5% minerals 1.8% Calcium dihydrogen phosphate 0.5% Choline chloride 0.3% multidimensional 0.2% Encapsulated Vitamin C 0.1% Antioxidants 0.02% probiotics 0.28% food attractant 0.3%

[0027] The feed was formulated according to the formula shown in the table above, and the grouper was raised for 60 days. The grouper fed the feed of this example is active, the feed has good viscoelasticity, good water stability, the grouper grows fast, the feed coefficient is 1.17, and the economic benefit is good.

Embodiment 3

[0029] Steam dried fish meal 70% pregelatinized starch 15% flour 10% Fermented soybean meal 0% High quality imported fish oil 0% beer yeast 2% minerals 1% Calcium dihydrogen phosphate 0.8% Choline chloride 0.3% multidimensional 0.2% Encapsulated Vitamin C 0.1% Antioxidants 0.02% probiotics 0.28% food attractant 0.3%

[0030] The feed was formulated according to the formula shown in the table above, and the grouper was raised for 26 days. The grouper fed the feed of the present example has active feeding, good viscoelasticity of the feed, good water stability, fast growth of the grouper, a feed coefficient of 1.12, and good economic benefits.

Abstract

The invention discloses rockfish powdery compound feed, which is suitable for feeding rockfish. The rockfish powdery compound feed is a mixture prepared from the following components in percentage by weight according to a processing method of powdery feed: 55 to 70 percent of steam drying fish meal, 15 to 20 percent of pregelatinization starch, 0 to 10 percent of flour, 0 to 10 percent of fermented soybean meal, 0 to 2 percent of high-quality import fish oil, 2 to 4 percent of beer yeast, 1 to 1.8 percent of mineral substance, 0.5 to 1 percent of monocalcium phosphate, 0.3 percent of choline chloride and 0.2 percent of multivitamin. Compared with other kinds of compound feed, the rockfish powdery compound feed has the advantages that: the cost reduction is maximum, the palatability, feed viscoelasticity and stability in water are high, rockfish grow quickly, feed coefficients are the lowest, the economic benefit is the best, and the cultivating effect is the optimal.

Description

technical field [0001] The invention relates to the field of fish compound feed, in particular to the field of grouper compound feed. Background technique [0002] Grouper is one of the most important high-grade marine aquaculture fish in my country. It has the advantages of fast growth, high survival rate, and high-density breeding resistance. Its commercial fish is smooth and tender, delicious and nutritious. With the increasing maturity of the large-scale artificial seedling technology of grouper, the artificial culture of grouper has been vigorously developed in Hainan, Fujian, Guangdong and other provinces. [0003] At present, the cultivation of grouper still uses fresh trash fish as the main source of bait, but the nutrition of fresh trash fish is unbalanced, the utilization rate is low, it is easy to cause water pollution, and it is easy to bring pathogenic bacteria, resulting in the prevalence of grouper diseases and mortality. raised. Grouper pelleted compound fe...
