A MIXTURE OF PLANT EXTRACTS CAN BE MORE EFFECTIVE THAN A COMMERCIAL ANTIBACTERIAL FEED ADDITIVE IN POULTRY CHALLENGED WITH CLOSTRIDIUM PERFRINGENS

摘要: To reduce costs in the production of poultry many birds are kept close proximity. This leads to infections that productivity and antibiotics given as prophylactics feed. has led development antimicrobial resistance with some evidence may be transferred human bacterial pathogens. The European Union banned use antibiotic feed additives animal production. One solutions this problem is using plant extracts. Many extracts were tested for activity against mechanism also by stimulation immune system bird or reducing inflammation due gut microorganisms. Antioxidant therefore play a role. An extract Combretum woodii leaves had good pathogens excellent anti-oxidant activity. By simple manipulation we could increase antibacterial crude extract. When it was small trial, relatively toxic vivo cellular assays. We then investigated several species have been used herbal medicines From selected two complementary different combinations these grape seed antioxidant trial. No significant differences found between positive controls, negative controls treatments. hygienic conditions under which bids decreased infection. Some gave statistically signicantly better results than Zn-Bacitracin, commercially additive challenged infecting Clostridium perfringens performance parameters. indicate potential productivity.
