Problems solved by technology

Domestic salmon feed manufacturers have always paid attention to reducing feed production costs by substituting cheap plant grains or some of their products for fish meal, while ignoring the impact of anti-nutritional factors in plant grains on salmon growth and metabolism; they only focus on shortening the production cycle of salmon, but not on the production of salmon. Less attention has been paid to improving the nutritional quality of commercial fish

Embodiment 1

[0040] (1) Preparation of germinating camelina: soaking: soaking camelina seeds in soaking solution for 3 hours, the dosage ratio of camelina seeds to soaking solution is 1g:5ml; germination culture: put soaked camelina seeds in germination equipment, Germinate at 28°C for 1-2 days until the bud length is 1-5 mm; the germinated Camelina A is obtained. The sprouting camelina A is removed from impurities, shelled, and then pressed at low temperature; the pressing process requires that the inner temperature of the oil press is lower than 88°C, the residual oil rate of the cake is lower than 8%, and the sedimentation needs to stand for 5-10 hours; Get sprouted camelina oil A and sprouted camelina meal A.

[0041] (2) Preparation of germinating camelina: soaking: soaking camelina seeds in soaking solution for 3 hours, the soaking solution contains calcium lactate at a concentration of 1-10 mmol / L, and the dosage ratio of camelina seeds to soaking solution is 1g:5ml; germination cul...

Abstract

The invention relates to an expanded sinking feed capable of improving the contents of ALA (Alanine), EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) of salmons and belongs to the technical field of processing of fish feed. The feed provided by the invention contains 15 percent to 39.45 percent of germinated camelina sativa; the germinated camelina sativa is cultured through germinating camelina sativa seeds and the length of buds is 1mm to 5mm. According to the expanded sinking feed provided by the invention, compared with feed which is not added with the germinated camelina sativa, the feeding coefficient is remarkably reduced (the absorption utilization rate is improved), and the contents of the ALA, the EPA and the DHA in the fed salmons are significantly improved. Furthermore the cost of raw materials for preparing the feed is low; no antibiotic or chemical drug are added; the expanded sinking feed has no pollution to the environment; no harmful components are remained in the salmons, the physiological functions of the salmons can be effectively improved, the physical properties of the salmons are enhanced, and the meat yield and the quality of the salmons are improved, so that the expanded sinking feed is applicable to various scales and various types of salmon production.

Description

technical field [0001] The invention relates to an extruded sinking feed capable of increasing the contents of salmon ALA, EPA and DHA, and belongs to the technical field of fish feed processing. Background technique [0002] Modern food nutrition research shows that the content of polyunsaturated fatty acids in the diet is closely related to the health of the human body, and the role of n-3 polyunsaturated fatty acids is particularly prominent. Increase the intake of n-3 polyunsaturated fatty acids in the diet It helps to maintain the physiological functions of cells, reduce blood lipids and cholesterol levels in blood, reduce blood viscosity, increase the activity of brain cells, thereby reducing the incidence of cardiovascular and cerebrovascular diseases. In particular, EPA and DHA in n-3 polyunsaturated fatty acids have important physiological effects on the human body. EPA has good functional effects on promoting the metabolism of saturated fatty acids in the body, pr...
