Abstract The present study assessed the effect of in-feed doses of an exogenous enzymes preparation and/or Saccharomyces cerevisiae on production performance, nutrient utilization, ruminal and blood serum measurements in goats. Sixteen lactating Nubian does (35.1 ± 0.8 kg) were utilized in a quadruplicated 4 × 4 Latin square design over a period of 88 days. Enzymes and/or yeast were included in a basal diet (control treatment) at doses of 4 g exogenous enzymes (EZ treatment), 4 g yeast (SC treatment), or 8 g of their mixture at 1:1 w/w (EZSC treatment). The EZ, SC, and EZSC treatments had greater (P
