Problems solved by technology

In recent years, with the development of the aquaculture industry, grass carp farming has become a traditional grass feed feeding method, which has been transformed into a feeding method based on concentrate and supplemented by green feed. The growth period of grass carp has also been shortened from two years to one year. The economic benefits have been significantly improved, but due to the high-density breeding conditions, the physique of grass carp fed with concentrated feed has decreased significantly, and the excessive breeding density will cause stress, reduce the resistance of fish to diseases, and lead to low survival rates. During the process, it is vulnerable to red skin

Embodiment 3

[0020] Embodiment 3: animal feeding test

[0021] In a freshwater fish farm in Zhejiang, 2,000 grass carp with basically the same growth conditions were selected and randomly divided into five groups. Small and medium-sized cages were used for high-density breeding, with 100 fish in each cage, and fed forage and some compound feed. Group 1 was fed with common commercially available compound feeds, groups 2~3 were fed with the compound feeds of Examples 1~2 of the present invention, and groups 4~5 were fed with the following comparative experiment examples 1~2 respectively. Months, the incidence and final survival rate during the recording period. The specific results are shown in Table 1:

Abstract

The invention relates to a compound feed for high-density cultivation of grass carps. The compound feed comprises the following raw materials in weight percentage: 15-25% of wheat shorts, 10-25% of distillers dried grains and soluble DDSG, 3-8% of fish meal, 8-18% of bean pulp, 7-15% of peanut meal, 5-12% of rapeseed meal, 5-10% of full-fat rice bran, 5-8% of meat and bone meal, 2-5% of zeolite powder, 1-3% of soybean oil, 0.8-2% of special feed additive for the grass carps, 0.2-0.3% of compound vitamins, 0.2-0.3% of compound microelements and 0.5% of table salt; and the sum of the weight percentages of all the raw materials is 100%. With the adoption of the compound feed for the high-density cultivation of the grass carps disclosed by the invention, the economic benefits of the cultivation of the grass carps can be obviously improved, four diseases of grass carp in a grass carp cultivation process can be obviously improved, and the survival rate is improved by 7-9%; and the feed conversion rate in the grass carp cultivation process can be effectively improved and the growth of the grass carps is accelerated.

Description

Technical field [0001] The present invention belongs to the field of aquatic animal breeding. It specially involves a combined feed for high -density breeding for grass carp. This combined with the feed can improve the immunity of grass carp and improve the "grass carp disease" in grass carp breeding. Background technique [0002] Grass carp is one of the four fish in my country and the main freshwater fish species in my country. The grass carp farming has the advantages of low feed costs and obvious economic benefits. EssenceIn recent years, with the development of the aquaculture industry, grass carp farming has become a traditional feed method of grass -feed to feed on concentrate -based and green feed, and the growth period of grass carp has also been shortened from two years to one year.Economic benefits are significantly improved, but due to high -density breeding conditions, the body fed by fine feed fed by fine feed has decreased significantly, and the breeding density is...
