Abstract
The objective of this study was to evaluate the effects of a commercial yeast culture (Saccharomyces cerevisiae) on weight gain and development of buffalo calves from water buffalo herd in north of Colombia. The buffalo calves (age: 71,12 +/- 22 days old) were randomly assigned to one of two treatments, during 45 days. One group (n=13) received 50 gr/day of commercial product of yeast and the other group (n = 13) don’t received yeast. The buffalo calves grazed in same pastures under same milking system. All animals were weighed and measured weekly. During the test the animals gain 11,38 +/- 5,2 Kgr y 13.92 +/- 5,0 Kgr by treated and non treated calves, respectively. The increase of the corporal measures during the test was (cm): Toraxic Circumference 7,0 +/- 5,58 Vs 9,23 +/- 4,02, Height 5,77 +/- 6,81 Vs 5,92 +/- 4,5 and Length 2,92 +/- 8,17 Vrs 0,54 +/- 4,86 by treated and no treated calves, respectively. No statistic difference was found between groups. In conclusion, the feeding with yeast culture didn’t increase significantly the weight gain and development in water buffalo calves.
