morphology while 5/pen were collected for determination of apparent digestible energy, nitrogen, and mucin content from ileal digesta. The higher (5X) dosage of the coccidial
vaccine resulted in an 11% reduction in crypt depth (P < 0.05), but there was no effect on villius length or number of goblet cells (P > 0.05). The dosage of coccidial vaccine had no effect on the apparent digestibility of energy or nitrogen. At Paracox® 1X dosage, birds fed the phytogenic feed additive had 12% longer villi than the control fed birds (P < 0.05) with 30% more goblet cells, and 23% more goblet cells per 10 microns villius length (P < 0.05). Neither coccidial vaccine dosage nor phytogenic supplementation influenced ileal mucin content (concentration or per unit of feed intake). Birds fed the phytogenic feed additive at a Paracox® 5X dosage had 4% less apparent digestible energy (P < 0.05), however at the Paracox® 1X dosage there was no effect of the phytogenic feed additive (P > 0.05). In conclusion, the dosage of coccidial vaccine can have an influence on the crypt depth and supplementation of the diet with a phytogenic additive increased villi length and goblet cell density.
