Abstrakt: Manganese (Mn) is an essential trace element for broiler chickens; its deficiency causes tibial dyschondroplasia (TD) characterized by lameness and growth retardation. Inorganic and organic manganese sources are used in global poultry production, but there is a lack of systematic investigations to compare the bioavailability among them. In this study, 120 1-day-old Arbor Acres (AA) broilers were randomly divided into four groups (n = 30), i.e., control group (Mn sulfate, 60 mg/kg), Mn-D group (Mn deficiency, 22 mg/kg), Mn-Gly group (Mn glycinate, 60 mg/kg), and Mn-Pro group (Mn proteinate, 60 mg/kg). During the 42-day experiment, growth performance, tibial bone parameters, pathological index changes, serum biochemical changes, and oxidative stress indicators were evaluated. These results not only suggested that Mn plays a crucial role in the normal development of tibia and the maintenance of redox homeostasis in broilers, but also proved that organic Mn supplementation, especially Mn proteinate, improved the tibia development and the absorption efficiency, as well as overall oxidative stress status of broilers, suggesting that it had greater bioavailability than inorganic Mn. Thus, application of organic Mn source may be an effective way to reduce economic losses and resolve animal welfare concerns due to TD in commercial poultry farming.
