Abstract
The invention relates to Atlantic salmon broodstock culture feed. Each kilogram of feed includes 430 to 450 grams of Arctic Ocean fish meal, 30 to 55 grams of expanded blood meal, 340 to 360 grams of expanded soybean, 60 to 80 grams of imported refined fish oil, 60 to 95 grams of special-grade flour, 2.5 to 6.5 grams of Vb, 4.7 to 7.5 grams of Vc, 20 to 40 grams of Ve, 1 to 3 grams of Vd, 8 to 15 grams of choline chloride and 8 to 12 grams of adhesive. The invention has the advantages that the invention can meet the nutrition requirements of the broodstock in the Atlantic salmon broodstock culture period, and promote the gonadal maturation of the Atlantic salmon brood stock, thereby reaching the breed standard.
Description
technical field [0001] The invention belongs to an animal feed, in particular to a breeding feed for Atlantic salmon broodstock. Background technique [0002] Atlantic salmon, also known as "salmon", belongs to Salmoniformes, Salmonoidea, Salmonidae, and is divided into two types: migratory and land-sealing. Native to the Pacific coast of North America, it is a cold-water fish. Under natural conditions, it mostly grows in water bodies where the water temperature does not exceed 20°C and the water quality is oligotrophic. It is a ferocious fish and feeds on small fish and shrimps under natural conditions. . The nutritional requirements of Atlantic salmon are different in each growth period. During the breeding period of Atlantic salmon broodstock, on the one hand, it is necessary to control the amount of unsaturated fat in the feed of the broodstock, and on the other hand, it is necessary to add additives that promote the maturation of the gonads of the broodstock to the fee...
