The Metabolizable Energy Content and Effect of Grape Pomace with or without Tannase Enzyme Treatment in Broiler Chickens
Two experiments were conducted to determine the chemical composition, metabolizable energy content and effect of grape pomace (GP) with or without tannase enzyme treatment on growth performance of broiler chickens. In experiment 1, the apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen (AMEn) of GP were determined as 2642.19 and 2641.08 kcal/kg, respect...

This study was carried out to investigate the effect of Natuzyme plus enzyme on energy and protein efficiency for weight gain and metabolizable energy and protein digestibility of diets containing wheat and canola meal in broiler chickens. Seventy two day- old Arbor acres broiler were used in completely randomized design with 6 treatments and three replicates for starting (1-21 d) and grower (2...

متن کاملModeling metabolizable energy utilization in broiler breeder pullets.
The objective of this study was to determine models for ME requirements for broiler breeder pullets using the factorial method. The influence of the temperature on maintenance ME requirements was determined by experiments conducted in three environmental rooms with temperature kept constant at 15,22, and 30 degrees C, using the comparative slaughter technique. The energy requirements for weight...
متن کاملApparent metabolizable energy of crude glycerin originating from different sources in broiler chickens.
An energy balance experiment was conducted to determine the AME(n) of various crude glycerin samples, and to generate an equation to predict AME(n) of crude glycerin based on its chemical composition. Dietary treatments consisted of a corn-soybean meal basal diet with no added glycerin and a basal diet supplemented with 6% glycerin. Crude glycerin samples were obtained from biodiesel production...
