Problems solved by technology

Some people have carried out research on feed formula for the nutritional needs of the growth of pomfret, such as Chinese patent CN200410026486, etc., but at present most of the pomfret culture still use fresh miscellaneous fish or low-quality feed, the feed coefficient is high, and it is harmful to the culture water body. The serious pollution of the environment leads to a low survival rate and a serious waste of resources.

[0014] Embodiment 1: Processing method 1 of green and environmentally friendly oval pomfret extruded feed

[0015] 1. Take steam fish meal 35kg, soybean meal 15kg, meat and bone meal 10kg, brewer's yeast 3kg, squid paste 3kg, high-gluten flour 24kg, shrimp head powder 4kg, lecithin 1kg, multivitamin (commercially available) 0.5kg, composite minerals ( Commercially available) 1kg, choline chloride 0.5kg, and high-quality fish oil 2kg are mixed evenly. Then, 30 g of astaxanthin, 40 g of carotenoids and 60 g of compound immune enhancer were added to each 100 kg of the above mixture. The compound immune enhancer is prepared by pre-mixing 20 g of beta-glucan, 20 g of skullcap, and 20 g of saccharoterpenes.

[0016] 2. Pulverize the above-mentioned mixed raw materials through an ultra-fine pulverizer, so that all components can pass through the 80-mesh sieve.

Abstract

The present invention is one kind of green compounded and puffed feed for egg-shaped silver anchovy and carangid. The green compounded and puffed feed is prepared with steamed fish meal 25-45%, soybean residue 5-25%, pork bone powder 5-20%, beer yeast 1-6%, cuttle fish paste 2-5%, fish oil 1.0-2%, macaroni flour 10-26%, shrimp head powder 3-6%, lecithin 0.5-1%, vitamins 0.3-0.5%, compounded mineral 0.5-1% and choline chloride 0.3-0.5%, and through homogeneous mixing, adding astaxanthin 20-30g, carotenoid 30-50g and compound immunopotentiator 50-70g to each 100 kg of the mixture, extruding to pelletize, and stoving. The green compounded and puffed feed has simple compounding process and balanced nutrients, can meet the requirement of the growth of egg-shaped silver anchovy and carangid and raise the immunity of egg-shaped silver anchovy and carangid, and results in less water contamination.

Description

[Technical Field] [0001] The invention relates to a method for processing green and environment-friendly oval pomfret extruded compound feed, which belongs to the field of compound feed and its processing. [Background technique] [0002] Oval pomfret, commonly known as golden pomfret, is a kind of precious edible fish. Its meat is tender and delicious, and it is deeply loved by people at home and abroad. In recent years, the breeding scale of oval pomfret has been expanding, and the quality of its feed is one of the key technologies for the development of its breeding industry. Some people have conducted research on feed formulations for the growth of oval pomfret, such as Chinese patent CN200410026486, etc., but most of the oval pomfret culture still uses fresh trash fish or low-quality feed, which has a high feed coefficient and is not suitable for aquaculture water. The pollution is serious, resulting in low survival rate and serious waste of resources. [Content of the...
