Highlights
The supplementation o f feeds w i t h pure or mixed cultures o f live microor ganisms can have benefitial effects o n animal growth and health
The strain 51R was identified as Lactobacillus salivarius, using results o f the A P I test and criteria of Kandler and Weiss (1986)
Lactobacilli represent the major group of microorganisms in the digestive tract o f chickens (Smith, 1965)
Summary
The supplementation o f feeds w i t h pure or mixed cultures o f live microor ganisms (probiotics) can have benefitial effects o n animal growth and health. The effects o f probiotics were attributed to the production o f antibacterial substance antagonistic to harmful bacteria, destruction of antinutritional factors, synthesis of vitamins, and provision of nutrients and digestive enzymes (Fuller, 1986). Beneficial effects o f lactobacilli administration on performance of chickens or laying hens were reported by Krueger et al (1977), Adler and DaMassa (1980) and Arends (1981). The aim o f this work was to administer lactobacilli per os to newly hatched chickens and enumerate lactobacilli and several specific groups o f bacteria in the crop and caeca.
