Continuous in vitro rumen systems.
I n vitro rumen experiments have been conducted for at least 40 years, and many research problems have been examined successfully by this approach. The simplest sub-division of in vitro rumen systems is into batchand continuous-culture types. The batch-culture approach involves the provision of an initial supply only of substrate, which results in a culture in which the concentration of substra...
متن کاملMaintenance of a certain rumen protozoal population in a continuous in vitro fermentation system.
A continuous culture system suitable for maintaining certain rumen protozoa was developed by modifying the procedure of Walter and Pilgrim (R.A. Weller and A.F. Pilgrim, Br. J. Nutr. 32:341-351, 1974) to include a dialyzing system. The concentration of ciliate protozoa, the pH value, and concentrations of volatile fatty acid and ammonia-N could be maintained within normal rumen limits for more ...
متن کاملEffects of the antibiotic monensin and an inhibitor of methanogenesis on in vitro continuous rumen fermentations.
1. The effects of a methane inhibitor, ICI 111075, and a propionate enhancer, monensin, were studied using in vitro continuous fermenters. 2. Both compounds increased the yield of substrate energy, carbon and hydrogen in volatile fatty acids (VFA). This was mainly due to an increase in the molar proportion of propionic acid. 3. Improved yields of VFA were accompanied by reductions in methane pr...
متن کاملIn Vitro Rumen Fermentation of Alfalfa
A L T H O U G H in vitro and in vivo rumen studies of cellulose digestion and volatile fatty acid production are numerous (Johnson, 1966), a paucity of information is available on the bioenergetics of tureen digestion. From four in vitro fermentations, in which the heat of combustion of substrate and the products was determined, Marston (1948) concluded that the heat of rumen fermentation of pu...
متن کاملSIMULATING CONTINUOUS FUZZY SYSTEMS: I
In previous studies we first concentrated on utilizing crisp simulationto produce discrete event fuzzy systems simulations. Then we extendedthis research to the simulation of continuous fuzzy systems models. In this paperwe continue our study of continuous fuzzy systems using crisp continuoussimulation. Consider a crisp continuous system whose evolution depends ondifferential equations. Such a ...
