Effects of a premolt calcium and low-energy molt program on laying hen behavior and heterophil-to-lymphocyte ratios.
The objectives of this study were to compare the behaviors, postures, and heterophil-to-lymphocyte ratios (H:L) of laying hens housed in a cage system when offered a Ca premolt treatment and low-energy molt diets vs. a traditional feed withdrawal (FW) treatment during and after molt. A total of 144 Hy-Line W-36 hens (85 wk of age), housed 3 hens/cage (413 cm(2)/hen), were used. Hens were allott...

An experiment was conducted using 504 Hy-Line W-36 hens (69 wk of age) to evaluate two low-energy non-feed withdrawal molt diets, each fed at three different rates. Treatment 1 consisted of feed withdrawal for 10 d (10-d fast) followed by feeding a 16% CP corn-soybean meal diet for 18 d. Treatment 2 consumed a 47% corn and 47% wheat middlings (C:WM) diet fed ad libitum for 28 d. Treatment 3 rec...
