Enzymatic extract of Trametes maxima CU1 on productive parameters and carcass yield of rabbits

The aim of this study was to evaluate the effect of the enzymatic extract (EnzE) of native fungus Trametes maxima CU1 on the productive parameters and carcass yield of rabbits. A total of 36 rabbits, 18 New Zealand and 18 California breeds were distributed randomly into two treatments; control (without EnzE supplementation) and EnzE2.5 (with 2.5% of enzymatic extract added to drinking water). All rabbits were fed with a commercial diet ad libitum. At 49, 71, and 91 d, data for body weight (BW), average daily feed intake (ADFI), feed efficiency (FE), and average daily gain (ADG) were collected. Moreover, dressing out percentage (DoP) and carcass fat yield (%CFY) were estimated. BW and ADFI were not different between treatments (P> 0.05). However rabbits supplemented with EnzE2.5 showed higher values compared to the control. Rabbits EnzE2.5 and New Zealand males showed the best productive efficiency at 49 d (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
