Effects of dietary oil source in pre-starter diets on growth performance, nutrient utilization, and organ weights in broiler chickens.

ABSTRACT: After hatching, broiler chicks transition from relying on yolk lipids to dietary nutrients. Providing dietary oils with a fatty acid profile similar to that of the yolk, particularly rich in oleic acid, may facilitate this metabolic shift. This study evaluated the effects of different oil sources in the pre-starter diet on growth performance, nutrient digestibility, and organ development in broiler chickens. A total of 2,016 one-day-old male Ross-308 broilers were allocated to three pre-starter diets (0-4 d) containing 30 g/kg of soybean oil, safflower oil, or sunflower oil (12 replicates of 56 birds). Pancreas, liver, and residual yolk weights were assessed at 3 d. Ileal digesta were collected at 4 d to determine DM, CP, ash, ether extract digestibility, and ileal digestible energy. After
