Effect of yeast and multi vitamin-minerals mix in diet to stimulate the growth performance of ducks and suppress pathogenic bacteria

Abstract

The research aims to examine the effect of a mixture probiotic yeast Saccharomyces spp. and multi-vitaminmineral
complex (Provinal) to stimulate the growth of ducks and bio-control pathogenic bacteria in the intestine
of ducks. Two hundred and forty one-day-old male ducks (Anas sp.) were used in a completely randomized
design experiment allocated into 4 treatments, namely: P0) rations without Provinal; ration with the addition of
0.1%; 0.2%; and 0.30% Provinal, as treatment P1; P2; and P3, respectively. All treatment diets were in the form
of mash containing 16% protein and 2900 kcal/kg metabolized energy. This study showed that administration of
0.10-0.30% Provinal increased average daily gains, feed efficiency, and feed digestibility (P<0.05). The
concentration of cholesterol in serum, fecal N-NH3, the number of Choliform and E.coli bacteria in the
intestines in treatments P1, P2, and P3, were lower (P<0.05) compared to P0. Conclusion that 0.10-0.30%
Provinal supplemented in rations of ducks were increased daily weught gains, feed efficiencies, and nutrient
digestibility but decreased serum cholesterol, N-NH3 in excreta, total population of Choliform bacteria and E.
coli in ducks.
