1. The present experiment was conducted to describe the effects of @entity4745 , @entity7655 and a commercial preparation of essential oil components (CRINA Poultry), in female broilers. Feed and water were provided for ad libitum consumption. 2. Feed intake, weight gain and feed:gain ratio were not different among the treatments. Water intake was significantly lowered by @entity7655 . Relative liver weight (g/100 g of body weight) was highest in birds given @entity4745 , but this was seen only at the age of 21 d and not at 40 d. Patterns of digestive enzymes in pancreatic tissue were similar for the 4 treatments. 3. Amylase activity in intestinal digesta was highest in @entity1573 given CRINA Poultry for 21 d, but the effect had disappeared after 40 d. Ileal digestibility coefficients for starch and protein were high and identical for all treatments. 4. @entity844 composition of diet was reflected in that of adipose tissue. Plasma lipid concentrations were not changed by any dietary treatment. 5. Thus, the present results show no effect of essential oil constituents on growth performance in female broiler @entity1573 , but it cannot be excluded that positive effects would have been observed under less hygienic environmental conditions or when using a less digestible diet.
