【 摘 要 】

The study was conducted to evaluate the effect of different dose of yeast probiotics on hematological profile of hemoglobin, erythrocytes, hematocrit, MCV, MCH, MCHC, RDW-CV, leucocyte, eosinophil, basophil, neutrophil, lymphocytes in blood of laying hens before and after received a Newcastle disease (ND) vaccine. Total of 80 laying hens (18-week) were randomly divided into four treatments. Each treatments consisting 4 replicate with 5 hens each. The first treatment was fed a basal feed as a control, and the second, third and fourth treatment were basal feed that supplemented with the yeast that contains 1x 109 CFU/g at the level of 0.5, 1.0 and 1.5 g/per kg of feed during 2 weeks observation. Layers were vaccinated with ND vaccine strain LaSota on 7 days after yeast supplementation treatment. Blood samples were collected on 24 h before and 5 h after vaccination. Results indicated that treated with yeast showed not significant effect on MCV, MCH, MCHC, RDW-CV, leucocyte, basil, neutrophils, lymphocytes. Yeast supplementation had significantly (p
