Embodiment 1
[0036] An abalone breeding base uses organic selenium-rich abalone feed to feed abalones. The abalone feed is composed of the following raw materials by weight: 2 parts of the aforementioned high-selenium corn flour, 1 part of high-selenium wheat flour, 1 part of high-selenium soybean flour, 20 parts of degummed kelp powder; 9 parts of kelp glue; 20 parts of white fish meal; 10 parts of soybean meal; 18 parts of flour; 5 parts of yeast; 10 parts of puffed soybean powder; 5 parts of spirulina; 1 part of calcium hydrogen phosphate; Total selenium content and organic selenium ratio, no adverse reactions were found in abalone during the breeding process. The specific breeding data of this example are shown in the table below.
[0037] Detection Indicator Feed of the present invention common feed Total selenium content (μg / kg) 356.3 89.2 organic selenium ratio 95% 72% mortality rate(%) 3.8 8.1 Growth rate (shell length cm) Initial 0.85, en...
