Effect of advanced chelate technology based trace minerals on growth performance, mineral digestibility, tibia characteristics, and antioxidant status in broiler chickens

Abstract

Background Compared to the corresponding source of inorganic trace minerals (TM), chelated supplements are characterized by better physical heterogeneity and chemical stability and appear to be better absorbed in the gut due to possibly decreased interaction with other feed components. Methods This study was designed in broiler chickens to determine the effects of replacing inorganic trace minerals (TM) with an advanced chelate technology based supplement (Bonzachicken) on growth performance, mineral digestibility, tibia bone quality, and antioxidant status. A total of 625 male 1-day-old broiler chickens were allocated to 25 pens and assigned to 5 dietary treatments in a completely randomized design. Chelated TM (CTM) supplement was compared at 3 levels to no TM (NTM) or inorganic TM. A corn–soy-based control diet was supplemented with inorganic TM at the commercially recommended levels (ITM), i.e., iron, zinc, manganese, copper, selenium, iodine, and chromium at 80, 92, 100, 16, 0.3, 1.2, and 0.1 mg/kg, respectively, and varying concentration of CTM, i.e., match to 25, 50, and 100% of the ITM (diets CTM25, CTM50, and CTM100, respectively). Results Diets CTM50 and CTM100 increased average daily gain (ADG), European performance index (EPI), and tibia length compared to the NTM diet (P < 0.05). Broilers fed the CTM100 diet had lowest overall FCR and serum malondialdehyde level and highest EPI, tibia ash, zinc, manganese, and copper contents, and serum total antioxidant capacity (P < 0.05). The apparent ileal digestibilities of phosphorus and zinc were lower in the ITM group compared with the CTM25 and CTM50 groups (P < 0.05). Broiler chickens fed any of the diets, except diet CTM25, exhibited higher serum glutathione peroxidase and superoxide dismutase activities than those fed the NTM diet, where the best glutathione peroxidase activity was found for CTM100 treatment (P < 0.05). Conclusions These results indicate that while CTM supplementation to 25 and 50% of the commercially recommended levels could support growth performance, bone mineralization, and antioxidant status, a totally replacing ITM by equivalent levels of CTM could also improve performance index and glutathione peroxidase activity of broiler chickens under the conditions of this study.

Changes in the chemical composition of broiler meat when chelated compounds are added to the diet

“…However, the fat in the meat of broilers treated with chelated compounds was higher in white muscle by 69.59 % and in red -by 41.05 %, compared with the control group (P < 0.05). Fat positively affects the texture and taste of poultry meat (Ghasemi et al, 2020).…”

Effect of replacing inorganic minerals with small peptide chelated minerals on production performance, some biochemical parameters and antioxidant status in broiler chickens

“…Their deficiency can cause specific symptoms such as reduced feed intake, growth retardation and even death ( Liu et al, 2014 ). Copper, zinc, manganese, and selenium are cofactors of metalloenzymes (superoxide dismutase, SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), playing an essential role in the antioxidant system and lipid peroxidation ( Barandier et al, 1999 ; Ghasemi et al, 2020 ). In practice, trace minerals are inexpensive and readily available.…”

“…Organic trace minerals have higher bio-availability for animals than inorganic trace minerals (ITM) due to its better chemical stability and physical heterogeneity of the chelate form ( Ghasemi et al, 2020 ). Organic trace minerals are absorbed through the amino acid or peptide transport system, which is the main reason for the increased bio-availability ( Muszyński et al, 2017 ).…”

Performance, Carcass and Bone Characteristics and Histological Structure of Some Organs of Broilers fed Inorganic or Organic Trace Mineral Premix

“…Organic minerals are chelating agents that help in better feed absorption and utilization in the body tissue. Using organic trace minerals at lower levels for animal diets have been suggested based on the hypothesis that such form of minerals has a higher bioavailability than inorganic form, and hence provides better immunity (Ghasemi et al 2020). Any mineral that is bound to organic compounds is considered an organic mineral, regardless of the type of existing bond between mineral and organic molecules.…”
