FERMENTATION IN THE RUMEN OF THE SHEEP

III. INTERMEDIATE STAGES IN THE FERMENTATION OF WHEATEN

HAY IN VITRO BY MICRO-ORGANISMS FROM THE RUMEN

pdf (With One Text-figure)

A previous communication in this series of papers (Gray, Pilgrim & Weller, 1951) gave an account of the fermentation of wheaten hay and lucerne hay by organisms from the rumen of the sheep, in which the overall production of each of the main volatile fatty acids was determined. In view of the complex nature of both the substrate and the mixed population of organisms involved, it was decided to investigate the intermediate stages of the fermentation to determine whether any

important changes take place in the composition or in the rate of production of the mixture of acids.

Rumen Microbiology

Method for Measuring Gas Production Kinetics

D.R. Mertens and P.J. Weimer

Introduction (pdf)

Methodology can play a critical role in the measurement of digestion kinetics, especially when the objective is to define kinetic parameters for feeds when formulating rations or modeling animal responses. Measurement of gas production kinetics provides the opportunity to evaluate the rate of digestion of the soluble, more rapidly fermenting fractions of feeds. However, differences among procedures that have little impact on digestion of dry matter after 48 h of incubation may have dramatic effects on fermentation of soluble matter during the first 20 h. Our objective was to develop a method for measuring the kinetics of gas production that would minimize any detrimental effects associated with the in vitro system and provide estimates of digestion kinetics that can be used to both describe feeds for ration formulation systems and provide parameters for models of ruminal digestion.

1. Introduction

Rumen liquor has been widely used as inoculum in some in vitro techniques of feed evaluation. This liquor has been firstly used by Tilley and Terry (1963) for their two-step technique of feed evaluation. It was then also applied in the rumen simulation technique (Czerkawski and Breckenridge, 1977) and in the gas producton technique (Menke, et al, 1979 and Theodorou et a, 1994) all over the world. Until now rumen liquor is still the only inoculum used in in vitro technique. (Bahasa Indonesia)
