Effect of Intermittent Lighting on Production Performance of Laying-Hen Parent Stocks
The objective of this observational field study was to investigate the effect of an alternative intermittent lighting program (13L: 5D: 1L: 5D – Trt) vs. standard lighting program (16L: 8D – Ctrl) on production performance of laying-hen parent flocks. Two houses of 15,000 Hy-Line brown parent-stock hens each were used for the comparative study. Hen-day egg production (HDEP), eggs per hen ho...
