Ruminant 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 ...
متن کاملFermentation of methanol in the sheep rumen.
Sheep fed a hay-concentrate diet were adapted to pectin administration and ruminal infusion of methanol. Both treatments resulted in a strong increase in the rate of methanogenesis from methanol. Quantitative data show that methanol was exclusively converted into methane. Treatments did not influence ruminal volatile fatty acid percentages.
متن کاملNatural Products as Manipulators of Rumen Fermentation
There is increasing interest in exploiting natural products as feed additives to solve problems in animal nutrition and livestock production. Essential oils and saponins are two types of plant secondary compounds that hold promise as natural feed additives for ruminants. This paper describes recent advances in research into these additives. The research has generally concentrated on protein met...

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...
