Abstract

The objective of the experiment was to evaluate the efficacy of Marine Sulfated Polysaccharide enhanced by a blend of
organic acids (AseaD) as an alternative to colistin in the diet of broilers. A total of two hundred and sixteen one-day-old male chicks (Ross 308, initial body weight: 42.25 ± 0.42 g/bird) were randomly assigned to 1 of 2 treatments each represented with 12 replicate cages of 9 birds. The dietary treatments included (1) basal diet with antibiotic (Control, basal diet + 20 ppm colistin) and (2) basal diet without antibiotic + 0.3% AseaD (AseaD). Birds in the control were fed a basal diet containing colistin from 1 to 28 days of age only. There were no differences in ADG and ADFI between the 2 treatments at any phases or for the overall period (P > 0.05). Similarly, no differences in FCR were found during d 1-28 or the overall period (P > 0.05). Nevertheless, the FCR of broilers fed AseaD (1.893) was lower than that of broilers fed the control diet (1.991) from 29 to 42 days of age (P = 0.016). No differences in the survival rate of birds were found between the 2 treatments (P > 0.05). These results confirm the potency of AseaD in broiler diets as a potential alternative to colistin used at a concentration of 20 ppm, with significant benefits and interest during the finishing period when colistin is withdrawn from a diet.
