Determination of the effects of cation-anion difference on rumen fermentation and feed digestion by in vitro method (DaisyII)

This study was carried out in vitro using DaisyII incubator to determine the effects of cation-anion exchange on feed digestion and rumen fluid. For this purpose, barley, vetch and barley straw, vetch hay were used. CaCl2 was used to decrease the CAD values of the rumen fluid and feed, and rock salt was used to increase the CAD values. In the study conducted in two trials, treatment groups were formed by changing the CAD values of rumen fluids in the first trial and feedstuffs in the second trial. The effects of rumen fluid and feeds on digestive properties were determined for each group. At the end of the study, IVTD and IVDMD values were highest in CaCl2 groups (P˂0.05). In the first experiment, the control group values were the lowest for all digestion values (P˂0.05). As a result, it was found that especially the changes in CAD in rumen fluid affect the digestion of feeds and the final products formed in rumen.
