Prophylactic administration of a 0.1% mixture containing ascorbic acid (AA) and a solid dispersion of curcumin with polyvinylpyrrolidone (CUR/PVP, ratio 1:9) and boric acid (BA) (AA-CUR/PVP-BA) on crop and cecal tonsils (CT) colonization of Salmonella Enteritidis (S. Enteritidis) 1 in broiler chickens (Experiment 1).

Data are presented in Log cfu/g of tissue. Mean ± SE from 12 chickens. 1 Chickens were orally gavaged with 107 cfu of S. Enteritidis per chicken at six-day old, samples were collected 24 h later. a,b Values within treatment columns for each treatment with different superscripts differ significantly (p < 0.05). For S. Enteritidis incidence, data are presented as positive/total chickens (percentage). * p < 0.05; ** p < 0.01.
