Utilization of rumen filtrate fermented corn-cobs by weaner rabbits

Abstract

A feeding trial was conducted to evaluate the feeding value of rumen-filtrate fermented corn cob (RFFCC) for weaner rabbits. Twenty-five rabbits were divided groups. Each group was further divided into five replicates, housed in individual rabbit hutches. RFFCC was incorporated in the diets at 0, 25, 50, 75 and 100% replacement for yellow maize. Feed intake increase progressively (P<0.05) with increased dietary level of RFFCC. Feed intake and average daily weight gain exhibited an inverse relationship. Feed: Gain ratio value increased with increasing dietary level of RFFCC, an indication of progressive decline in the efficiency of feed utilization Feed: Gain ratio was however not affected up till 25% RFFCC inclusion level (i.e 50% replacement of dietary maize). The result of the experiment showed that RFFCC posses some potential as a feed resource for the rabbit. It was concluded that RFFCC should not constitute more than 25% of total diet as this will result in impairment of performance.
