Abstract


Growth stimulators on basic of probiotics are preparations biological character with correctly defined strains live micro organisms. Most important signification their used consisted in positive stimulation natural micro flora of digestive tract therefore fortified mechanisms of autoimmunity system of organism, what very narrowly relate with achieved utility animal parameters. Healthy and vital individuals marking better nutrient utilisation, equally growth intensity consistent higher slaughter yield. Propoul is two - elemental probiotic preparate designated for poultry, which include special selected strain of genus Lactobacillus. Results their affect is improve of immunity, metabolism and also favourable effect on utility.In 42- days experiment we tested effect of probiotic preparate Propoul on basic fattening parameters of hybrid Hubbard JV. We divided broiler chickens into three groups - control (C) without probiotic, experimental 1(E1) with decreased probiotic amount during fattening period and experimental 2 (E2) with constant concentration of testing preparate). Propoul in fluid form we was applicating in drinking water. Effect of probiotic positive manifested in all observed parameters. With exception organic growth and growth index, where we founded favourable effect his application especially in first two weeks in all other both experimentals by expressive rate dominated in achieved values in compared with control. Mostly, from aspect average live weight, where we recorded from 2. week to end of fattening period statistically high significant (P<0.01) and statistically very high significant difference (P<0.001) in benefit of E1 and E2 groups.
