Effect of Butyrate on Clostridium and Chronic Enteritis 1) Direct inhibition at “intestinal” pH of ALL pathogenic strains from 5 animal species (broilers, pigs, rabbits, calves, horses) • Improving mucosa integrity offering less substrate (nutrients) to Clostridium perfringens (needs 13-14 Ess. AA’s). • Better digestion & absorption less undigested nutrients 3) Anti inflammatory effect on G.I.T. (Enteritis = Inflammation) 4) Selective stimulation and inhibiton of various clusters of Clostridiaceae : Inhibition of Cluster I (pathogenics) Stimulation of Cluster IV and IVX (butyrogenic)

GREENCAB 70 COATED RESULTS IN ANIMAL PRODUCTION
Greencab 75 P versus ABGP - CONFIDENTIALExperimental Station of European Industrial Company • Large experiment set up by European Feedmill to evaluate two commercial alternatives (Provimi, Nutreco) versus Avilamycin (CTR+) • Calcium butyrate at 4 levels was taken as other positive control : 60, 180, 300 and 420 grams per ton. • Outcome : * All calciumbutyrate groups performed better than the two commercial products. * All calciumbutyrate groups gave similar performance as 10 ppm avilamycin and better litter scores. * The lower dosages, 60 and 180 grams gave the better economy : 1.1-1.2% lower cost per kg of meat produced. Feedcost (%) 100 98.9 98.8 99.8 99.6
