Impact of Dietary Different Trace Mineral on Performance, Egg Quality, Oxidation Status, and Immune Responses of Female Broiler Breeders

Abstract

Abstract This study aims to compare the effects of different forms of minerals on the performance, egg quality, oxidation status, and immune response of female broiler breeders. A total of 432 healthy Hubbard white feather female broiler breeders were randomly divided into 3 groups (6 replicates of 24 birds each). Group A was fed a basal diet supplemented with inorganic trace elements, Group B with methionine hydroxyl analog chelated trace minerals, and Group C with proteinate trace minerals for a 56-day feeding trial period. There were no significant differences observed in performance and egg quality between the dietary inorganic and organic trace elements (P > 0.05). However, the inclusion of organic trace elements in the diet led to improved activities of total superoxide dismutase (T-SOD) and catalase (CAT), as well as reduced concentrations of malondialdehyde (MDA) in plasma and eggs (P < 0.05). Furthermore, compared to Group A, Groups B and C exhibited enhanced concentrations of E2, PROG, and LSH in plasma, and Group C showed improved levels of IgA and IgM (P < 0.05). In conclusion, the inclusion of dietary organic trace elements, specifically metal methionine hydroxyl chelates and metal proteinate, has been shown to enhance antioxidation and immune function in female broiler breeders. Therefore, the use of proteinate trace elements is recommended in broiler breeder diets.
