Effects of Dietary Fat on Feed Efficiency, Reproductive Performance, and In Vitro Lipogenesis by the Turkey Hen

Abstract Two 16-week feeding trials were conducted with Large White turkey hens to determine the effect of graded energy levels (as fat – 6, 18, 30, and 42% substituted isocalorically for corn meal) on energy efficiency, reproductive performance, lipogenic enzyme activity, and in vitro lipogenesis. A constant calorie:gram-protein ratio (17:1) was maintained for all dietary treatments. Also, other components of the diets were adjusted to maintain constant energy-to-nutrient ratios. Additional fat increased (P
