Abstract
Several variables associated with the composition and management of bovine waste and various grains (corn, milo, barley) and their level of supplementation (25%, 50%, 75%) in rations were evaluated to determine their effect on initial volatilization of ammonia (NH3), amines, hydrogen sulfide (H2S), and odori-ferious compounds Dry matter (DM) and crude protein (CP) content of feces were not correlated (P>.10) with initial NH3 volatilization. Urea content and specific gravity of urine were positively correlated (P<.10) with the NH3 initial evolution rate. The grain source altered the pH of waste (P<.05) with milo producing the lowest pH and barley the highest. NH3 volatilization showed a positive correlation (P<.05) with pH of waste. Urea from urine was the primary precursor of the initial NH3 volatilized with maximum release of NH3 occurring between the second and fifth day of storage. Volatile amines accounted for approximately .11% of the total nitrogen volatilized and were positively correlated (P<.01) with NH3 evolution. Addition of sagebrush at 1% and 1.5% levels showed no modification (P>.10) of olfactory evaluation of the waste. Peppermint oil at the .25% level in the diet reduced (P<.05) the relative offensiveness associated with the waste. Copyright © 1979. American Society of Animal Science .
