Patent DE-1946661-A1 (DE)
Title: Use of bifidus microorganisms for growing - and fattening animals
Inventor: SCHULER ROLF DR
IPC: A23K10/18
Filed: 1969-09-15
Abstract: Some of the microorganisms of the Bifidus group can settle and multiply in animal intestines, suppressing diseases, reducing mortality (by 50% or more). and promoting the growth and fattening of animals. The bacteria are grown at first in a conventional solid nutrient medium; then transferred in a liquid nutrient medium containing 0.1-5% (pref. 0.1-2%) of a yeast extract or autolysate; the liquid medium is added gradually to the culture, as a high concentration of the bacteria is essential for their multiplication. The culture is added to a compatible fodder in an amount of 5-100g/kg of the animal body. The settlement and multiplication of the bacteria is checked by analysing excrements of the animals.
