PSXIII-21 Formulations of Vitamin K, Organic Acids, Essential Oils and Plant Hydroalcoholic Extracts Prevent Coccidiosis Impact on Growth Performances in Broilers

Abstract The aim of this study was to evaluate the effect formulations vitamin K, organic acids, essential oils and plant hydroalcoholic extracts as anticoccidial alternatives in broilers. A 34-day cage trial with 10 replicates 12 birds/cage conducted. Male broilers (Ross 308) were randomly assigned to: 1) non-infected (NI); 2) Eimeria-infected (EI); 3) EI+decoquinate/zoalene shuttle program (DZ); 4) EI+2 kg/t Nutri-Gro® feed additive; 5) 3 L/1000 L Technocok® drinking water from d14 d20. made by Synergie Eurobec International Ltd contain 7.0 7.5 g/kg K. Eimeria infection induced an oral administration at 2x105 sporulated oocysts mixed species field isolates. Data analyzed a model including treatment barn section fixed random effects, respectively, Kruskal-Wallis tests. As expected, coccidian challenge (EI) reduced growth performances, increased total excreted oocyst counts (6.0 vs 3.0 log10, P < 0.0001) E. acervulina (0.79 0.21, P=0.0022) tenella (2.04 0.17, intestinal lesion scores (ILS) 6 days post (dpi, d20), compared NI, whereas DZ palliated these impacts. two formulation treatments d20 body weight (BW), EI (0.980 0.939 0.908 kg, 0.01), without improving conversion ratio (FCR). 2 (2.69 2.61 P=0.0486) showed trend improve (2.68 P=0.1015) d34 BW, birds.
