Abstract

An experiment was conduct to evaluate the effect of different additives around intestinal integrity and performance from broilers by infectious stress. We used 240 broilers and 4 experimental diets: control diet without additives, probiotic, essential oils and antibiotic. Weight gain (WG),feed intake (FI), feed conversion (FC), as well as height, width and density of villi, crypt depth (CD) and the ratio of villi height by crypt depth (V:C) of the intestinal segments were evaluated. The essential oils diet at 28 days found major (P < 0.05) lesion score. The lowest CD and highest V: C ratio (P<0.05) found in animals received antibiotics at 21 and 28 days. Diets with probiotic and antibiotic provided higher (P <0.05) FI and WG in the 21 day period. However, animals receiving the probiotic diet did not present better (P<0.05) FC. With the exception of FC at 21 days, the diets analyzed did not improve (P<0.05) the performance and the lesion score of the animals in relation to the control diet. [ABSTRACT FROM AUTHOR]
