Abstract: Study to feed biochemical fulvic acid(BFA) influence milk performance,blood biochemical indicators , somatic ceel count and mastitis resistibility of dairy cows .Selectting 50 lactation cows were divided into test group and control group. Research results showed that milk yield , milk fat percentage and SOD ,GSH-PX content in serum for dairy cow of BFA test group were increased 5.99% , 8.50% 3.6% and 7.72% respectively than the control group.Somatic cell count, LDH content in serum for dairy cow of BFA test group dropped 40.09% and 9.3% respectively than control group. Milk protein percentage , MDA content in serum and WBC of blood for dairy cow of BFA test group did not change significantly. The all test index are not significantly different (p> 0.05). The experiment of feeding BFA for dairy cows showed that BFA enhance the body resistance and milk performance.
Key words: Biochemical fulvic acid; Dairy cows; Somatic cell count; Performance; Biochemical indicators
