Validation Of The Effects Of Small Differences In Dietary Metabolizable Energy And Feed Restriction In First-Cycle Laying Hens, G. R. Murugesan, M. E. Persia

An experiment was conducted to evaluate energy utilization of laying hens fed diets containing 2 ME concentrations, using response criteria including performance, BW, abdominal fat pad, and energy digestibility. The experiment was a 2 × 2 factorial with 2 feeding regimens (ad libitum and restriction fed), and 2 dietary ME levels [2,880 kcal/kg of ME (CON); and 2,790 kcal/kg of ME (LME)]. A total of 60 Hy-Line W36 first-cycle laying hens were fed experimental diets, resulting in 15 individually caged hens for each of the 4 treatments. Hens in the restriction-fed group were fed 90 g of feed per day. …
