چکیده
the aim of this study was to compare the effects of three antibiotic alternatives with a control (antibiotic-free) and an antibiotic diet on performance and gut morphology of broilers reared on litter. 600 day-old ross-308 chicks were assigned to 48 pens in a crd design with 6 × 2 factorial arrangements, in which 2 levels of chick density (5 and 7.5 chicks/m2) and 6 experimental diets (control, virginiamycin, fermacto, bactocell, biostrong and biostrong matrix-value formulated or biostrong-mv) were used. higher chick density increased starter feed intake and decreased grower feed conversion ratio (fcr) significantly (p
