| Summary: | <p>A 30-day broiler cage trial was conducted to evaluate the effect of dietary mannan oligosaccharide (MOS) from one commercial product (SAF-Mannan) on growth parameters, gut health and control pathogen colonization of broilers<sup> </sup>under C<em>lostridium perfringens</em> (<em>C. perfringens</em>) challenge. One hundred, 0-day old male Ross 308 broilers were allocated in 4 experimental<sup> </sup>treatments for 30 days. The four dietary treatments were T1, standard broiler basal diets without any medication as a control (+CONT); T2, basal diets as in T1 plus <em>C. perfringens</em> challenge (-CONT); T3, enramycin 0.1 g/kg of feed plus <em>C. perfringens</em> challenge (ENRA); T4, SAF-Mannan at 0.5 g/kg in starter and finisher diets plus <em>C. perfringens</em> challenge (SAF). Overall, feed conversion ratio (FCR) and body weight gain (BWG) in treatments ENRA and SAF were significantly better (P<0.01) than the –CONT treatment, whereas treatment +CONT was intermediate and not different from SAF. Feed intake (FI) was not influenced by treatment. SAF-Mannan supplementation was able to lower the ileal <em>C. perfringens</em> count as compared to all other treatments (P<0.05). The changes in <em>C. perfringens</em> count appear in parallel to observed improvement in the cumulative FCR. The results from this study clearly indicated that SAF-Mannan could act as a replacement for antimicrobial growth promoters in broilers (AGPs). SAF-Mannan level of 0.05% was enough to achieve a response competitive with that of the antibiotic.</p> |
