In vitro effect of pH on resistance of ruminal bacteria to intracellular potassium depletion, and effect of pH and ionophores on ammonia and microbial protein production Efeito do pH in vitro sobre a resistência de bactérias do rúmen à perda de potássio intracelular e efeito do pH e de ionóforos sobre a produção de amônia e proteína microbiana

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2005
Ruminal fluid from steers fed on pasture was incubated with artificial media at pH 5.5 and 7.0 in two experiments. In the first, the effect of monensin level on resistance of ruminal bacteria to potassium depletion was evaluated; in the second, effects ...
