Effect of Dietary Choline Chloride Supplementation on Growth Performance and Carcass Characteristics of Broiler Chickens Reared to 32 Days of Age

Research on the impact of supplementing additional dietary choline to modern, large-frame broiler chickens is limited, and current recommendations are outdated. The objective this study was determine effect chloride supplementation growth performance carcass characteristics modern broilers reared 32 days age. Corn soybean meal-based diets were formulated contain an 0, 400, 800, 1200, 1600, or 2000 mg per kg feed above present in basal diet ingredients. As-hatched Ross 708 × Yield Plus chicks (n = 2160; 30 birds pen; 44 ± 0.2 g initial BW) randomly allotted experimental diets, for 31 days, processed at day 32. Growth performance, yield, breast myopathy incidence not impacted by supplemental choline. However, abdominal fat pad weight tended diminish with increasing choline, drumstick yield reduced fed over 800 feed. These results indicate feeding does but may result changes high-yielding days.
