ABSTRACT
The main objective of the present study was to evaluate the effectsof the dietary addition of different levels of rosemary powder (RP) andvitamin E (VitE) on broiler performance and gut gross morphometry.A total of 270 one-day-old Ross 308 male chicks were randomlyassigned to nine dietary treatments with three replicates of10 birdseach. Treatments consisted of diets were supplemented with 0, 0.5or 1.0% RP and 0, 100 or 200 mg/kg VitE (alpha-tocopherol acetate).Feed intake and weight gain were recorded weekly. On day 42, onebird per replicate was euthanized after blood sampling. Gastrointestinaltract segments were measured and/or weighed. Means were comparedby least significant difference. Overall, broilers fed1.0% RP presentedlower (p< 0.05) feed intake, weight gain, and final weight body thanthose fed 0.5% RP. Broilers fed the 0.5% RP plus 200 mg/kg VitE dietpresented higher weight gain (p<0.05) in than those in the controlgroup (0% RP and 0 mg VitE). Jejunum length and weight, colonlength and width, and right cecum weight were also negatively affected(p<0.05) by the 1.0% RP diet when compared with the 0.5% RP diet.We suggest that the dietary supplementation of 0.5% RP plus 200mg/kg of vitE improves broiler performance and does not have significantadverse effects on gross gut morphometry. Dietary VitE may play apotential protective role against the negative effects of high levels of RP.
