Performance of rats orogastrically dosed with faecal strains of <i>Lactobacillus acidophilus</i> and challenged with <i>Escherichia coli</i>

VO Oyetayo


Albino rats (Rattus norvegicus) were orogastrically dosed with faecal strains of Lactobacillus acidophilus and simultaneously infected with Escherichia coli, while the control was challenged with E. coli alone. The treatment was repeated the second day and post ingestion period of 18 days follow. It was observed that rats dosed with L. acidophilus and simultaneously challenged with E. coli treatments have better performances when compared with the control for daily weight gain, total weight gain and feed conversion rate. Faecal materials of rats dosed and challenged do not show sign of diarrhoea which was observed in the E. coli only treated rats.

Key Words: Rats, orogastric, Lactobacillus acidophilus.
