The experiment was carried out to evaluate the increasing levels of anatto extract (AE) oil in sorghum-based diets as the main energy source. A total of 280 laying hens in the second production cycle, 140 Lohmann Selected Leghorn (LSL) and 140 Isa Brown (IB), was allotted to a density two birds/pen and full fed seven diets. The treatments consisted of a positive control corn based diet, as principal energy source, and a basal sorghum diet, as principal energy source, supplemented […]
