摘要：
The invention refers to an alkali granulated additive for animal feed with high concentration of lysine, but especially low ammonium content. More particularly, said alkali granulated additive has pH within the range between 8 and 10, including a lysine concentration between 70% and 85% by weight and having a nearly negligible content of ammonium ions which the molar relation follows the condition below:[NH4+][LLys]<10-2being obtained by a process wherein, during the fermentation step inside fermentation tanks, concentration levels of ammonium ions in the solution are controlled by monitoring the rate of ammoniacal nitrogen (AN) throughout processing and fermenting culture medium, so to keep said content of ammoniacal nitrogen (AN) around 100 mg/l until it is close to the end of the carbon source in the culture medium is detected and, subsequently, promote a controlled reduction of the content of the ammoniacal nitrogen (AN) until it reaches amounts between 50 mg/l and 10 mg/l, which will be controlled and monitored until the end of the carbon source in the culture medium.
