چکیده
This study evaluated the effects of live yeast (LY, Saccharomyces cerevisiae) on growth performance, nutrient digestibility, immune function, antioxidant status and intestinal morphology broilers. A total 224, 1 day-old broilers were assigned 4 treatments (7 replications, 8 chicks each) fed a basal diet control group (CTR); antibiotic (CTC) diets with chlortetracycline at 75 mg/kg; LY-1 LY-2 groups treated LY 500 1000 mg/kg, respectively. Final body weight was greater (p < 0.05) in compared CTR. Crude protein retention higher both than that After immunization birds Newcastle diseases Infectious bursal disease vaccine, antibody titers CTR or CTC day 35. Super oxide dismutase catalase enzyme values increased those 42. Total cholesterol lower Villus height jejunum ileum Live can be useful as possible alternative to antibiotics

Dietary putrescine effects on performance parameters, nutrient digestibility, intestinal morphology and tissue polyamine content of broilers fed low protein diet
This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...
