Abstract

The purpose of this study was to evaluate the effect of using ruminal fluid on the conversion of some agricultural waste to the concentration of its evapotral fatty acids. Experimental treatments were 100 g of wheat straw, rapeseed straw, corn stalk wheat straw, incubated at constant level of 2 liters of rumen fluid for 24 hours, two 12-hour and 4 hours incubation. After the incubation time was completed, the concentration of ruminal fluid escaping fatty acids processed with food samples was determined. The results showed that the processing of oral samples with ruminal fluid significantly increased the amount of acetic acid (P <0.05). The amount of propionic acid in different food samples significantly decreased with increasing processing time (P <0.05). The processing of oral samples with ruminal fluid significantly increased the amount of butyric acid (P <0.05). Overall, the results of this study indicate that ruminal microorganisms have the ability to convert lignocellulosic waste to a higher degree of digestibility and a combination of activated charcoal and therefore have the ability to use in the processing of agricultural waste.
