Influence of dietary acetylsalicylic acid on abdominal fat deposition and performance of broiler chicks fed high and low fat diets

Abstract

One hundred fifty day-old Hybro male broiler chicks were fed from hatching to 3 weeks of age 2 isonitrogenous and isocaloric experimental diets. 75 birds were fed a high fat diet (HF) and the other half was fed a low fat diet (LF). Sixty birds of each treatment were assigned to 4 pens and fed 4 diets (HF, LF, HFA, LFA) from 21 to 42 days. The HFR and LFR diets were formulated to contain 1 g aspirin per kg of diet. All the diets used were isocaloric and isonitrogenous. Chicks fed HF diets had a bodyweight greater than those fed LF diets, but the difference was significant only at 3 weeks of age. Percent abdominal fat was significantly lower for the LF diet at 6 but not 3 weeks of age. A significant decrease in percent abdominal fat and increase in plasma glucose were obtained with aspirin. Growth rate, feed efficiency or feed intake were not significantly depressed in birds fed diet containing aspirin from 21 to 42 days of age
