Relationships between Mineral Metabolism and Rumen Fermentation in Sheep

Fermentation 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.

Dynamic Changes of Main Rumen Microflora and Ruminal Fermentation in Sheep Supplemented with Molasses-Urea

The digestion and utilization of roughage by sheep depends on rumen digestion. The aim of this study was to evaluate the microbe quantity and fermentative efficiency of rumen supplement with molasses-urea. This experiment was conducted in 2014, eight sheep were selected and divided into two groups (a control group and a treatment group), and only the treatment group animals were supplied with m...

The fermentation of carbohydrates in the rumen of the sheep.

The majority of workers are agreed that the digestion of carbohydrate in the rumen is brought about by the micro-organisms living there, and furthermore, that the microflora plays a much larger part in these processes than the microfauna, for if the Protozoa are removed by drenching with dilute copper sulphate, the digestive processes continued unhampered (see Van der Wath, 1942). The precise r...
