Comparative Study on the Effect of Lactina® Probiotic on Some Microbiological and Histological Characteristics of the Digestive Tract of Muscovy Ducklings

A study on the infl uence of Lactina probiotics on the content of some microbial species and some histological characteristics in the intestine of Muscovy ducklings has been conducted. The authors proved, that Lactina probiotic had a signifi cant effect on the microfl ora in the large intestines, suppressing the development of the enterococci and pathogenic bacteria of Salmonella species and stimulating the development of the lactic acid bacteria. The structure of the intestinal wall corresponded to an active functional status, no signifi cant differences being established in the histological structure between the experimental and the control groups.
