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 molasses-urea for ad libitum consumption. Rumen fluid was collected every 2 h and rumen fermentation parameters were measured. The populations of majority bacteria were investigated by real-time PCR. The results showed that the populations of majority bacteria increased in the rumens of treatment group animals (P
