Summary A miniature artificial rumen technique for studying fiber digestion by rumen bacteria and a method for determining fiber was described. The reproducibility, uses, and limitations of the technique were discussed. One example of the use of this technique was a study of the in vitro effect of antibiotics on the digestion of fiber by rumen bacteria. The use of the miniature artificial rumen in field work was described. Other uses of this procedure were suggested.
SUMMARY: Toluene-treated washed suspensions of rumen bacteria break down proteins largely to amino acids; in the absence of toluene bacterial deaminases are active. Unlike the d...
A simple technique for the determination in vitro of the dry‐ or organic‐matter digestibility of small (0·5 g) samples of dried forages is described. It involves incubation firs...
Rates of in vitro cellulose digestion were determined for mature timothy (seed ripe) which had been ball-milled 0, 6, 24, and 72 hr.The total amount of cellulose digested increa...
Tilley et al . (1) have clearly demonstrated that their rumen liquor and pepsin procedure for the determination of digestibility of herbage is useful and precise. The method has...
Published data which allow the comparison of the digestive powers of cattle and sheep were analyzed statistically. Comparisons were made for the digestibility of organic matter,...
