Abstract
Twenty-Four New-Zealand White rabits rabbits about 35 days of age were assigned to four groups. Treatment consisted of two levels of crude protein: high and medium. Each treatment was tested with and without Deodorase (Yucca Plant Extract: YE) at 250 mg/kg diet. Body weight and feed intake were recorded weekly. At the end of the experimental period, six animals from each group were sacrificed to measure blood and cecal ammonia and urea nitrogen, cecal pH and cecal volatile fatty acids. There was an increase in body weight due to protein level and Deodorase. The same trend was observed for total body gain. There was an improvement in the feed/gain ratio due to the high levels of protein and inclusion of Deodorase. There was a decrease in cecai pH due to Deodorase, but this was not significant. Cecal pH was affected by protein level. Volatile fatty acids were increased with high levels protein groups. The Deodorase groups showed decreases, although non­significant, in blood ammonia and urea nitrogen. The high protein groups showed a significant (P<0.0001) and non-significant increase in blood urea nitrogen and blood ammonia, respectively, compared with medium protein groups. It can be concluded that, dietary YE with high levels of protein or concentrates reduced the susceptibility to diarrhoea or enteri­tis problems and gave a good performance.
