between 20,400 and 37,000. The birds were weighed per house on day 0, 14, 21 28 and at slaughter. Further, antibiotic use for gut health issues was assessed in days and dose. Gut health was evaluated macroscopically in five to six randomly chosen animals per house. Presence of coccidiosis was as- sessed according to a scale ranging from zero (no coccidiosis) to four (severe lesions)9


level, ten intestinal parameters were assessed10


. For an estimation of dysbacteriosis . All assessed


parameters show statistically significant differences (P < 0.05) when using the product. An improvement in average end weight of 60gr and a reduction in feed conversion ratio (FCR) of four points was obtained in birds in the trial group. The bacterial enteritis score improved with 11.2%.


Good alternative for broilers These data support the previous observations on the benefi- cial effect of esterified fatty acid based products on the in- testinal health of poultry. A possible explanation for the syn- ergistic action of esters with different chain length might be that short chain esters improve epithelium regeneration, therefore reducing the leakage of plasma proteins in the lumen and making the attachment to the epithelial barrier


more difficult to bacteria, which, in turn, leads to the reduc- tion of inflammation11,12


medium and long chain acids has been previously docu- mented13


, which helps the reduction of inflammation by


killing or inhibiting the growth of Clostridium perfringens. In vivo experiments on necrotic enteritis in broilers have shown that lauric acid is capable of reducing necrotic lesions in the gut14


. The improvement in production parameters


such as average end weight and FCR could be possibly due to the overall increased nutrient digestibility because of the delayed gastric emptying, stimulation of pancreatic and intestinal enzymes, better development of intestinal villi, increase of the activity of brush border enzymes and adsorp- tion of nutrients15 numerous trials16,17,18


, which was previously documented in . In conclusion, the product reviewed


in this article has been demonstrated to be effective in re- ducing bacterial enteritis lesions and overall improving pro- duction parameters in field conditions in broilers as an alter- native to antibiotic prevention and treatment of bacterial enteritis in broilers.
