Embodiment 1
[0041] 1. Preparation of Bioactive Selenium
[0042] Add 0.3g of Candida utilis yeast extract, 5g of sodium acetate, 1g of ammonium oxide, 1g of potassium dihydrogen phosphate, 0.5g of magnesium oxide, and 3g of sodium bicarbonate into 1000ml of distilled water, stir to dissolve, boil to sterilize, and cool down to 32°C Afterwards, Rhodopseudomonas sanguinus (Rhodopseudomonas palustris Rps.Rutila) was inoculated at a ratio of 5 wt%. After cultivating in a solar greenhouse at 25°C-26°C for 3 days, add sodium selenite in an amount such that the selenium content of the feed additive made is 800mg / kg (calculated as Se), and continue to cultivate for 5 days, and the material gradually turns dark red. , indicating that it has matured. Sampling and testing showed that the number of live bacteria was 1.0-1.1 billion / ml. Absorbed with bran and dried to make selenium-containing microbial feed additive. Stir into lactating cow feed and feed directly to cows. When the selenium content...
Embodiment 2
[0044] Add 1g of yeast extract (brewer's yeast Brewer'Sreast), 3g of sodium acetate, 5g of ammonium oxide, 3g of potassium dihydrogen phosphate, 0.1g of magnesium oxide, and 1g of sodium bicarbonate into 1000ml of distilled water, stir to dissolve, boil to sterilize, and dehumidify After reaching 32 DEG C, it is 0192 (Rhodospirilium1 total 1 strain) that inserts Rhodospirilium bacterial classification by the ratio of 10wt%; Cobalt, its amount is 1200mg / kg for making the selenium-containing feed additive of making (in terms of Se), continue to cultivate 3 days, and material turns into crimson gradually, shows that ripe. Sampling and detection, the number of viable bacteria can generally reach 1.9-2 billion / ml. The selenium-containing microbial feed additive is prepared by absorbing and drying rapeseed meal. Stir into lactating cow feed and feed directly to cows. When the selenium content in the dairy cow feed is 1-1.5mg / kg, the selenium content in the milk (liquid milk) produ...
Embodiment 3
[0046] Add 0.1g of yeast extract (Sphaeromus utilis), 1g of sodium acetate, 0.1g of ammonium oxide, 5g of potassium dihydrogen phosphate, 3g of magnesium oxide, and 10g of sodium bicarbonate into 1000ml of distilled water, stir and dissolve, boil for sterilization, and dehumidify to After 32°C, inoculate Rhodopseudomonas strains (Rhodopseudomonas globosa Rps.Globiformis) in a proportion of 8wt%, place in a solar wet room at 28°C-29°C for 2.5 days, and then add calcium selenite or Selenium, its amount is that the selenium-containing feed additive of making is (in terms of Se) 500mg / kg concentration, continues to cultivate 3 days, and material turns dark red gradually, shows that ripe. Sampling and detection, the number of viable bacteria can generally reach 1.3-1.5 billion / ml. Absorbed with bran and dried to make selenium-containing microbial feed additive. Stir into lactating cow feed and feed directly to cows. When the selenium content in the dairy cow feed is 1-1.5mg / kg, t...
