The Effect of Aspergillus oryzae on Performance of Swine
Keywords:Aspergillus oryzae, Amaferm, Monogastric Probiotic, feed additive, average daily gain
Abstractn experiment was conducted focusing on the effects of Aspergillius oryzae (Amaferm®) on maternal and growth traits of swine. In stage one, sixty-one sows were assigned to either a group receiving 0.046 oz/d of Aspergillius oryzae top dress on the sow feed daily or to a control group which did not receive Aspergillius oryzae. Feed intake, body condition, return to estrus, piglet weaning weight, piglet gain, and piglet average daily gain were observed. Treatment showed no significant effect on feed intake, body condition, piglet weaning weight, or return to estrus of sows. There was a significant negative effect on piglet gain (P<0.01). Stage two utilized piglets (N=412) from stage one. Piglets reared from treatment sows received Amaferm®, and piglets reared from control sows received the control diet. Treatment and control were fed ad libitum, and treatment received Aspergillus oryzae at the rate of 0.024 oz/lbs of feed. Weight gain, average daily gain, feed intake, and feed-to-gain ratio were measured. Treatment had no significant effect on all observations. Amaferm® had no positive effect on maternal or growth factors in swine.
