Popis: Optimising the feed composition, especially the forage choice, and reducing costs are essential for improving dairy production efficiency. Different forage sources and proportions were used to formulate rations containing equal energy and protein, and their effects on rumen microbiota and milk production performance of dairy cows were evaluated in two experiments. In experiment 1, thirty lactating cows (235 ±13 d postpartum; milk production 29.1 ± 1.0 kg/day) were divided into Pangola and Bermuda groups. In experiment 2, twenty lactating cows (79.9 ± 8.1 d postpartum; milk production 34.7 ± 0.6 kg/day) were divided into Pangola and oat groups. In experiment 1, the Simpson index for rumen microbiota of the Pangola group was significantly higher than in the Bermuda group (P
