Rates of production of volatile fatty acids in the rumen of grazing sheep and their relation to ruminal concentrations.


I . The rates of production, or entry rates, of acetic, propionic and butyric acids in the rumen of grazing sheep have been measured by a radioisotope technique previously used on penned animals. 2. Regression equations were derived relating entry rates to ruminal concentrations. The equations from penned and grazing sheep did not differ significantly. 3… (More)
