FIG. 1.

Effect of caprylic acid on cecal C. jejuni counts in 15-day-old chickens. Values (means ± standard errors of the means) per treatment (n = 10 birds/treatment per trial) represent the population of C. jejuni in the cecal content of 15-day-old broiler chickens. In each trial, chicks (except for negative controls) were orally challenged 3 days posthatch with a mixture of five C. jejuni isolates (n = 10 chicks/treatment per trial; average dose of 2 × 10⁶ CFU/ml). Caprylic acid was added to the feed at 72 h prior to necropsy. Columns within the same trial (1 to 3) with different letters (a, b, c, and d) denote significant differences between doses (P < 0.05). All Campylobacter data were log₁₀ transformed for statistical analysis (5).
