Comparisons of Two Strains of Lactobacillus acidophilus as Dietary Adjuncts for Young Calves¹

Oklahoma State University, Stillwater 74074

ABSTRACT

Numbers of facultative lactobacilli increased in fecal flora of neonatal dairy calves during 2 wk following birth. This was accompanied by reductions in numbers of coliforms in feces. Calves that were fed pasteurized whole milk containing cells of Lactobacillus acidophilus exhibited greater increases in numbers of lactobacilli and greater reductions in numbers of coliforms. More lactobacilli and fewer coliforms were found in small intestines of calves which received L. acidophilus than in control calves. The strain of L. acidophilus isolated from the intestine of a young calf produced greater changes than did a strain of human origin. The incidence or frequency of L. acidophilus among lactobacilli isolated from fecal samples of calves was higher in animals that consumed L. acidophilus of calf origin than in the other groups. Thus, the strain of L. acidophilus of calf origin was more effective as a dietary adjunct in the calf than was the strain of human origin.
