Problems solved by technology

[0005] Fish meal has the characteristics of high content of essential amino acids and fatty acids, low carbohydrate content, good palatability, and easy digestion and absorption by animals. It has always been an indispensable high-quality protein source in seawater fish feed. It determines the quality of the feed, so that the amount of fish meal in the compound feed is very large, which not only increases the cost of the compound feed, but also discharges a large amount of nitrogen and phosphorus to the environment, causing aquaculture pollution

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with examples, but the embodiment of the present invention is not limited thereto, according to the above-mentioned content of the present invention, in conjunction with general technical knowledge and conventional technical means in this field, without departing from the above-mentioned basic technical idea premise of the present invention Various other modifications, substitutions or alterations can be derived.

[0016] Table 1 is the formula of Examples 1 to 9 of the present invention, and the measurement unit of each raw material is g / kg feed. Each raw material was weighed according to the ratio shown in Table 1, and were crushed through a 40-mesh sieve and mixed uniformly, and then passed through an F-26 (Ⅲ) twin-screw extruder to produce particles with a particle size of 2.5 mm. Among them, Examples 1 to 5 are high-efficiency growth-promoting compound feeds for oval pompano with differe...

Abstract

The invention discloses an efficient growth-promoting mixed feed for Trachinotus ovatus, which comprises the following raw material components by mass percent: 0-40% of fish meal, 10-19% of bean pulp, 0-18% of corn protein powder, 10-24% of soybean protein concentrate, 7% of peanut pulp, 13.7-17.9% of flour, 3% of sleeve-fish visceral meal, 6.5-8.4% of fish oil, 1% of lecithin, 2% of vitamin complex, 2% of composite mineral, 0.5% of choline chloride, 0.1% of high-stability vitamin C, 0-1% of crystal lysine and 0-0.3% of crystal methionine. The mixed feed has good feeding promoting property, is balanced in nutrients, strong in disease resistance and high in digestivity, improves the culture survival rate, accelerates growth and can lower the feed coefficient.

Description

technical field [0001] The invention relates to a fish feed, in particular to a high-efficiency growth-promoting compound feed for oval pomfret. Background technique [0002] Trachinotus Ovatus is a warm-water pelagic fish with rich nutrition, good taste, easy cooking and other characteristics. It is distributed in major aquatic product wholesale markets, supermarkets and restaurants all over the country. It belongs to the domestic popular consumption species and is a high-quality breeding object developed in China in the past ten years. [0003] Oval pompano is distributed in the East China Sea, South China Sea and Yellow Sea in my country. The main breeding areas are in coastal areas such as Guangdong and Hainan. The breeding methods include pond (seawater and brackish water) culture and cage culture (traditional cage and wind-resistant cage) , is one of several mariculture fish species that currently use compound feed in large quantities. [0004] The intensive and larg...
