Abstract

Two dietary protein levels (16.5% and 16.5 +2% urea) were fed to New Zealand White weanling rabbits about 35 days of age, each±250 mg Yucca Plant Extract: YE/Kg diet, with 6 rabbits in each of 4 groups. 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 caeca! ammonia and urea nitrogen, coecal pH and, coecal pH volatile fatty acids. There was an increase in body weight in body weight in 16.5% protein groups with or without Deodorase com­pared to 1 6.5% plant protein+urea. The same trend was observed for total body gain. Also, there was an improvement in feed/gain ratio in plant protein and inclusion of Deodorase. Volatile fatty acids were inco­reased with inclusion of urea or Deodorase. Coecal NH3 and blood urea N were decreased with inclusion of Deodorase especially in 16,5% pro­tein+urea. In general, Deodorase resulted in decrease in blood ammonia, blood urea nitrogen, and decrease in coccal urea nitrogen. Coecaal NH3 was reduced with YE when 2% urea was fed. Thus, Deodorase might im­prove N utilization in rabbits, particularly when diets containing urea are fed.
