Fig 2. Performance data of piglets treated with two different doses of yeast or water.

Piglets were treated by oral gavage with either 5 x 10⁹ cfu (Low) dose or 2.5 x 10¹⁰ cfu (High) dose of live yeast or sterile water (Control) every other day starting from day one of age until weaning. Body weight was recorded at regular intervals and presented either as average piglet weight in kilograms (A) or average daily weight gain in grams (B). Error bars represent SEM. Pooled data for low dose and high dose yeast groups were also compared against control piglets (C, D). Error bars represent SEM; bars with different letters are significantly different at P < 0.05.
