Some factors affecting fermentation capacity and net growth of rumen microorganisms.
The fermentation rate of rumen microorganisms obtained from a sheep fed on hay was determined at different hours after feeding. The highest rate of fermentation was obtained immediately after feeding whereas the lowest rate was always before feeding. The effect of adding glucose, sucrose, and starch alone or in combination with urea, sodium citrate, or succinic acid on the maximal fermentation ...
متن کاملRuminant Nutrition: Rumen Fermentation Modifiers
The objective of this study was to evaluate the effects of Rumensin and Tylan in feedlot diets containing wet distillers grains plus solubles. Eight hundred beef steers (329 ± 25 kg) were blocked by initial BW and randomly assigned to one of five treatments (20 steers per pen, 8 pens per treatment). Treatments consisted of a corn-based diet with Rumensin and Tylan (CORN+RT) and four treatments ...

The in vitro gas test was conducted to investigate the effects of cellulase (CEL) and xylanase (XYL) on in vitro rumen fermentation and microbial population with r...
متن کاملThe Control and Manipulation of Rumen Fermentation
The loss of energy which occurs in the rumen fermentation can be very appreciable (Czerkawski, 1969) and it is therefore not surprising that efforts are being made to find ways of manipulating the fermentation to minimise this loss. The area has been reviewed by Marty, (1972), Demeyer and Van Nevel (1975) and Czerkawski (1969). In addition to the energy consideration a number of conditions exis...
متن کاملAssimilation of Inorganic Cobalt into Rumen Microorganisms
Assimilation of ionic cobalt by axenic cultures of four species of anaerobic rumen bacteria was measured using 6oCo as cobalt (II) chloride. Uptake could be measured in all four species but may not represent active accumulation in the case of Lactobacillus casei and Propionibacterium acnes. Significant uptake (89.5% of 6oCo present) was demonstrated by Selenomonas ruminantium from media contain...
