Embodiment 1
[0018] A selenium-rich ornamental crab feed additive. The additive includes the following components in parts by weight: yeast selenium: 10 parts, compound bacteria: 25 parts, folic acid: 0.4 parts, and glucose: 6 parts.
[0019] Furthermore, the yeast selenium is obtained by culturing yeast in a selenium-enriched medium.
[0020] Moreover, the selenium compound added in the selenium-enriched medium is calcium selenite.
[0021] In addition, the organic selenium content in the yeast selenium is 95%.
[0024] A selenium-enriched ornamental crab feed additive, which comprises the following components by weight: yeast selenium: 5 parts, compound bacteria: 22 parts, folic acid: 0.5 parts, and glucose: 3 parts.
[0025] Furthermore, the yeast selenium is obtained by culturing yeast in a selenium-enriched medium.
[0026] Moreover, the selenium compound added in the selenium-enriched medium is calcium selenite.
[0027] In addition, the organic selenium content in the yeast selenium is 93%.

Abstract
The invention provides a selenium-enriched ornamental crab feed additive which is characterized by being prepared from the following components in parts by weight: 5-15 parts of seleniumyeast, 20-30 parts of compound bacteria, 0.2-0.5 part of folic acid and 3-10 parts of glucose. The selenium-enriched ornamental crab feed additive is added into feed for breeding ornamental crabs, selenium is added into the feed, and other medicinal materials are not required, so that the disease resistance and survival rate of ornamental crabs can be improved, and the breeding benefit of the ornamental crabs is greatly improved. Furthermore, yeast selenium serving as a high-quality organic selenium source has a high absorption rate and can be saved in an ornamental crab body after the physiological needs of the ornamental crabs for selenium are met, selenium deficiency is prevented from happening once again in a short period, and durability is achieved.
Description
technical field [0001] The invention relates to the technical field of feed, in particular to a feed additive for selenium-enriched ornamental crabs. Background technique [0002] With the improvement of people's living standards, ornamental crabs have become the object of more and more households. Due to the limitation of natural food sources, artificial feed has become an essential tool for raising ornamental crabs. The advantage of artificial feed is that its source is relatively stable, not restricted by seasons, and the feed formula can be adjusted at any time according to the different nutritional needs of crabs in different stages of growth and development. It not only meets the nutritional needs of crabs, but also reduces the cost of breeding. At present, with the continuous expansion of the scale of ornamental crab breeding, the requirements for artificial feed are getting higher and higher, and the market urgently needs a high-quality ornamental crab feed that is ...
