title: Effect of energy on the performance of broiler chicks fed various levels of monensin.
abstract: A total of 768 female broiler chicks in two experiments was fed diets containing 0, 100, or 120 mg monensin/kg of diet with and without added animal fat, in a 2 X 3 factorial design. Chicks were grown in electrically heated battery brooders and supplied feed and water ad libitum for 21 days. Animal fat fed at 6.8% of the diet consistently improved body weight, daily feed intake, and feed conversion regardless of monensin level. Monensin at 100 and 120 mg/kg of diet, in general, decreased these performance criteria progressively. Daily monensin intake was related to the concentration of monensin in the diet. Intake per unit of body weight was increased by reducing fat or increasing monensin.
