Abstract

|
|
An Experiment was conducted to investigate the effects of Natufermen®(Aspergillus oryzae) supplementation on the performance, ammonia gas production, microbial population in manure and serum IgG in pigs. Forty eight cross bred(YLD) weanling pigs(35d old) were assigned to 4 treatments; Control(C), C + Natufermen 0.1%, C + Natufermen 0.2% C+natufermen 0.3% for 6 week feeding trial. Each treatment had 4 replications of 3 pigs each. Natufermen® supplemented treatments tended to increase ADG and ADFI, but there were no significant differences among treatments. Supplementation of Natufermen® at the level of 0.2% improved ADFI/ADG(P<0.05). Ammonia gas production from manure was not significantly affected by treatments. All Natufermen® treatments increased in DM, crude ash and phosphorus digestibility(P<0.05). Serum IgG decreased as supplemention level of Natufermen® increased(P<0.05). Supplemtation of Natufermen® at 0.1% and 0.2% increased fecal Lactobacilli population at 3 wks after feeding treated diets(P<0.05).
It is concluded that supplementation of Aspergillers oryzae product Natufermen® improved feed conversion ratio and digestibility of DM, crud ash and phosphours. Fecal ammonia gas production was not significantly affected but serum IgG level was decreased and CFU of fecal Lactobacilli was increased at 3 wks after feeding Natufermen® supplemented diets.
