This experiment was conducted to compare the effect of probiotic thepax® in diets with different quantities of protein on the performance of Cobb-500 broiler chickens and their serum antibody level against Newcastle disease vaccine (NDV). Two basal diets were formulated based on NRC (1994) recommendations which had NRC (sufficient protein diet) and 90% NRC (low protein diet) for protein. The ba...

‏ This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the tr...
