| imple technology is not available for quantitatively detecting and measuring ammonia production from livestock bedding. The effect of control (C), boric acid (B), pine oil (PO) and their combination (M) on ammonia production, growth of ureolytic and mastitis causing bacteria was studied in different bedding materials (sand, straw, corncobs, woodshaving, newspaper and sawdust) contaminated with livestock (cow, horse, pig) urine or chicken manure. Kitagawa tubes were proven to be suitable for semi-quantitative detection of ammonia. Urine and beddings are the main sources of ureolytic bacteria. Treatments showed different levels of inhibition depending on bedding used and urine source. In general (PO) did not affect ammonia production (P... |
