Environment-friendly nutritional compound feed capable of improving body color of sparus latus cultured in pond or net cage

Abstract

The invention discloses environment-friendly nutritional compound feed capable of improving the body color of sparus latus cultured in a pond or a net cage. The compound feed comprises 20%-40% of fish meal, 3%-6% of extruded soybeans, 5%-20% of soybean meal, 5%-15% of peanut meal, 1%-3% of fine bran, 4%-8% of corn protein powder, 15%-30% of flour, 2%-6% of wheat gluten protein, 2%-5% of phospholipid oil, 2%-5% of fish oil, 2%-6% of body color modifier, 0.2%-0.5% of decavitamin, 1%-3% of compound minerals, 0.3%-1% of phagostimulant, 0.05%-0.15% of choline chloride, 0.02%-0.04% of mildew preventive, 0.01%-0.03% of chromium picolinate, 0.2%-0.5% of vitamin C phosphate ester, 0.01%-0.03% of beta-glucan, 0.01%-0.03% of Vitamin E and 0.02%-0.05% of high-temperature-resistant phytase. The environment-friendly nutritional compound feed aims to solve the problem that the body color of the sparus latus is dark when the sparus latus is cultured in the pond or the net cage, promote the sparus latus to grow quickly and enhance the immunity and resistance to diseases of the sparus latus.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to an environmentally friendly and nutritious compound feed that can improve the dark body color of yellowfin seabream caused by pond or cage culture, and belongs to the technical field of aquatic feed. Background technique [0002] Yellowfin seabream (sparus latus Houttuyn), commonly known as yellow wall, yellow foot stand, red wing, etc., belongs to the suborder Pencoidei, the family Sparidae, and the genus Sparus, and is widely distributed in Taiwan, Zhejiang, and Fujian. , Guangdong coastal areas and Japan, North Korea, Philippines, Indonesia and other regions. The body of the yellowfin seabream is oblong and flattened on the sides; the back of the body is narrow and gradually slopes from the starting point of the dorsal fin to the tip of the snout, and the ventral surface is blunt and slightly curved. The head is medium-sized, the front end is pointed, the eyes are medium-sized, a...

Problems solved by technology

This has also caused the degradation of yellowfin seabream seed resources in recent years, the growth rate has slowed down, the immunity and disease resistance have been weakened, and the disease damage has been serious

At the same time, some farmers do not meet the nutritional needs of yellowfin sea bream and feed them at will, resulting in a dim color of yellowfin sea bream and a sharp drop in commodity value.

This not only caused significant economic losses to the farmers, but also affected the sustainable development of the yellowfin aquaculture industry
