    SYNERGISTIC EFFECT OF DIETARY LIVE YEAST AND OLIGOSACCHARIDE ON GROWTH PERFORMANCE OF BROILER CHICKEN
    (DEPARTMENT OF ANIMAL NUTRITION, GENETICS AND BREEDING, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA -1207, 2019-12) AKHTER, SHARMIN
    This study was conducted to evaluate the effect of feeding graded levels of live yeast (Saccharomyces cerevisiae) and oligosaccharide on broiler performance. One-day old of Cobb-500 broiler chicks (n=150) were randomly allocated into five treatments. Each dietary treatment consisted of 3 replicates having 10 broilers in each of the replication. The dietary treatment contained no live yeast and oligosaccharide considered as control (T 0 ) and the other four treatments were T (2g yeast and 0.5g oligosaccharide/kg feed), T 1 (1g yeast and 0.5g oligosaccharide/kg feed), T (1g yeast and 1g oligosaccharide/kg feed) and T 4 3 (2g yeast and 1g oligosaccharide/kg feed). During the experimental periods of 4 weeks, feed intake, body weight gain, feed conversion ratio (FCR), survivability, flock uniformity values were calculated. Growth performance parameters were significantly (P<0.05) affected by experimental diets. Birds fed 1g yeast and 1g oligosaccharide/kg feed gained superior body weights (1765.90±4.89g) compared to control (l469.43±18.29g), and other dietary treatment. The mean body weight gains (g) at the 1 , 2 nd , 3 rd and 4 th week of different treatment groups were significantly higher (P<0.05) than control group. The feed intake of T (1g yeast and 1g oligosaccharide/kg feed) group was lower (2307.30±3.66g) compared to control (2421.07±25.99g). The groups fed diets containing 1g yeast and 1g oligosaccharide had lower FCR (1.33±0.00) compared to control (1.69±0.03). The inclusion of different dietary treatments had no significant (P>0.05) effects on survivability and flock uniformity. It is concluded that live yeast and oligosaccharide can be included in broiler diet at the rate of 1g yeast and 1g oligosaccharide/kg feed for better performance and higher economical return. 3 st 2
