Sažetak
Broilers (N=20 in each of 4 groups) kept under standard management conditions, were given various doses of salinomycin over a period of 8 weeks. They showed no clinical signs throughout the study. Those receiving 60 ppm, 120 ppm or 180 ppm salinomycin had significantly lesser body mass (P<0.001) than the control group. There was a significant negative correlation between dose of salinomycin and mass gain in broilers (r=-0.845, P<0.05). Cumulative feed conversion ratio (CFR) during this period was 2.21 in the control group compared with 3.251, 3.859 and 4.161 in broilers, respectively, receiving 60 ppm, 120 ppm and 180 ppm salinomycin in feed. There was a positive correlation between FCR and the dose of salinomycin (r=0.973, P<0.001). Organ index of liver, proventriculus, intestines and caeca in salinomycin at 60 ppm and 120 ppm had a non-significant influence on gizzard, kidneys and heart, but at 180 ppm there were significantly reduced gizzard and kidney indices compared with the control (P<0.001). On the other hand, heart index was significantly higher in 180 ppm fed broilers compared with the control (P<0.001). Grossly and histologically visceral organs of broilers receiving various doses of salinomycin appeared normal.
