IMPROVED PERFORMANCE OF LAMBS GIVEN BIOPLUS AND RUMENOX

Abstract

This study was to evaluate how far local probiotics Bioplus and Rurnenox (a
mixture of Saccharomyces cerevisiae yeast and dried colostrum) could improve feed
digestibility and average daily gain (ADG) of young animals. Twenty four of 6 mo
old lambs weighing about 9.5 kgs were divide randomly into 2 groups of l2 (based
on sex and average LW). They were kept in individual pens and consumed 485 g
DM intake consisting of fresh chopped king grass, commercial concentrate and soya
bean waste (57 1 36 :7 DM). Water was available at all time. The grass was otfered
afier bot.h concentrate and soya bean wastes were consumed. Each lamb in either
group was given 50 g Bioplus at the begiruting of the trial and 4 g Rtunenox daily
for 8 weeks. To estimate the ADG, the animals were weighted before and after the
trail. Feed efiiciency was also estimated. The digestibility value was estimated at the
last week of the study. Means were tested statistically by using t-test. Dry matter
digestibility increased significantly from 52 to 60 (P< 0.05) while the ADG
improved from 45 to 77 g/day (P< 0.05). Consequently, feed efliciency increased
from 0.09 to 0.16 (P< 0.05). It was concluded that additional Bioplus and Rumeuox
in the diet were recommended in the diet of the animals.
