Abstract

Objective: To compare the effect of strains and levels of YEAST on FATTENING CALVES.Design: 2x3 factorial arrangements.Animals: Thirty five male Holstain calves (average live weight 296.8 kg).Procedure: Animal were divded into five experimental groups each receiving a diet supplemented with one of the two strains of YEAST SACCHAROMYCES CEREVISIAE including ScA7 (Biosaf) and (Iran mayeh) at tow different leves (expressed as x and 2x) or controldiet (noyeast).The amount of x were 2.5 and 5 g 1/100kg LW/d for Biosaf and Iran mayeh, respectively. The diet containd forages and concentrate (70:30 ratio). Average daily gain and feed intake of each calf were measured during 135 days of the experimental period. At the end of the fattening period rumen liqure were obtained at 0,3 and 6 hours post -feeding. Blood samples were also taken at 0 and 3 hours post -feeding and subjected for the blood metabolites analysis.Statistical analysis: The completely randomized desigin and the randomly complete block design with analysis of covariance. Result: Growth rate was improved (p>0.05) in the animals using Biosaf at the level of x compared with those of control group (1457 vs1351g/day). Despite that feed intake did not differed between the animals, the addition of Biosaf made cause a better feed conversion rate and higher rumen pH than the of other treatment. The total number of RUMEN BACTERIA was also increased numerically. No changes on blood serum metabolites were observed. Conclusion: The use of YEAST Biosaf may result in a better stability of rumen pH and so increase RUMEN BACTERIAl population which in turn can improve ruminal fermentation and growth rate in calves.
