Comparison of banana flower powder and sodium bicarbonate supplementation on rumen fermentation and milk production in dairy cows

摘要: Four Holstein-Friesian crossbred dairy cows were randomly assigned according to a 2 × factorial arrangement in 4 Latin square design study the effect of banana flower powder (BAFLOP) and sodium bicarbonate (NaHCO3) supplementation as rumen-buffering agents on rumen fermentation milk production. The first factor was two ratios roughage concentrate (R : C) at 60 : 40 40 : 60, whereas second sources buffering agent (BAFLOP NaHCO3) supplemented 20 g/kg dry matter intake. All fed total intake 25 bodyweight untreated rice straw used source. Feeding R : C 40 : 60 increased nutrient digestibilities, nitrogen absorption, allantoin excretion microbial synthesis, crude protein efficiency synthesis both BAFLOP- NaHCO3-supplemented groups. BAFLOP could maintain ruminal pH NaHCO3. Blood urea nitrogen, volatile fatty acid propionate, yield NaHCO3 supplementation, acetate relatively high consuming 60 : 40. However, microorganisms similar among treatments compositions unchanged by dietary treatments, except fat solids highest cow consumed results suggested that feeding resulted improvement digestibility, production, showed capacity Therefore, be efficiently promisingly deserves replacement for lactating diet.
