Feed Intake and Nutrient Digestibility, Rumen Fermentation Profiles, Milk Yield and Compositions of Lactating Dairy Cows Supplemented by Flemingia macrophylla Pellet

Feed intake and nutrient digestibility, rumen fermentation profiles, milk yield compositions of lactating dairy cows fed with Flemingia macrophylla pellet (FMP) were evaluated. Four crossbred in early lactation randomly allocated into a 2×2 factorial arrangement 4×4 Latin square design (LSD). The first factor was protein level concentrate mixtures consisted two levels, i.e., 14% 16%. second supplementation levels FMP 0 150 g/cow/d. There no interactions between the on feed composition cows. findings revealed that both factors significantly impacted intakes. They also increased digestibility CP neutral detergent fiber (NDF). Ruminal ammonia nitrogen propionate (C3) concentrations improved (p<0.05), while acetate (C2), ratio C2:C3, estimated methane (CH4) production, protozoal counts subsequently reduced (p<0.05). Crude additionally absorption utilization, as well microbial synthesis. Milk production by feeding. In conclusion, concentrated mixture 16% along at dose g/cow/d could increase end-products, synthesis, mitigated CH4 rice straw.
