| Abstract: | Effect of urease inhibitors acetohydroxamic acid (AHA), catechol, hydroquinone (HQ) and borax on rumen microbial urease of sheep and soybean urease were studied in this trial. At concentration of 0.0001, 0.001, 0.01and (0.1) mmol/L of the urease inhibitors, soybean urease activity was inhibited by AHA by 6%, 6.2%, 9.66% and (29.79)%, HQ by 8.4%, 13.03%, 19.79% and 44.75%, catechol by 20.34%, 19.12%, 83.16% and 93.78%, and borax by 16.55%, 17.18%, 18.95% and 35.5%. At the same concentration as above, rumen microbial urease was inhibited by AHA by 9.58%, 14.04%, 41.3% and 72.73%, HQ by 12.21%, 39.99%, 64.62% and (78.87)%, catechol by 6.07%, 9.36%, 31.29% and 50.44%, and borax by 4.97%, 8.63%, 21.78% and 32.02%. |
