บทคัดย่อ (EN): Four crossbred (75% Holstein Friesian) lactating dairy cows with average live weight of 503±40 kg and 120±12 Days in milk (initial milk production of 12±2 kg/cow/d) were randomly assigned according to a 2×2 factorial arrangement in a 4×4 Latin square design to receive four dietary treatments. The four treatments were T1) 16% CP of concentrate(conc.) without mago-pel; T2) 16% CP of conc. with mago-pel 300 g/hd/d; T3) 19% CP of conc. without mago-pel; T4) 19% CP of conc. With mago-pel 300 g/hd/d. All cows received concentrate at proportion of 1 kg concentrate per 2 kg milk yield, and urea-treated rice straw (UTRS) was given ad libitum. The results were found that total dry matter intake and nutrient digestibility were similar among treatments (P>0.05). Rumen fermentation parameters such as pH, and NH3-N concentration were not affected by neither protein levels nor Mago-pel supplementation (P>0.05), however concentration of blood urea nitrogen (BUN) was significantly different between protein levels (P<0.05). Bacterial and fungal populations were not different among treatments (P>0.05) while population of protozoa was decreased when cows received Mago-pel supplementation (P<0.05). There were no interactions between protein levels and Mago-pel supplementation on any parameters. Therefore, 16% CP of concentrate was sufficient for the cows and Mago-pel 300 g/hd/d could reduce rumen protozoa.
