Effect of advanced chelate technology-based trace minerals on growth performance, mineral digestibility, tibia...

This research aimed to assess the impact of diet supplementation of Advanced Chelate Technology-based Mineral (ACTMS), on the Ross and Arian broilers performance. 520 broilers, of two strains, were allocated to 8 treatments (4 for each strain), 5 replicates, (13 chicks/replicate) and reared for 42 d. The treatments include 0 (CONT), 250 (SBC₂₅₀), 1,000 (SBC₁₀₀₀), and 2,000 (SBC₂₀₀₀) of ACTMS. Feed intake, weight gain, and feed conversion ratio were recorded, and the European Production Efficiency Factor (EPEF) was also calculated. Serum antibody was measured in response to sheep red blood cell (SRBC) to evaluate humoral immune response. Blood sample and tibia were used to measure the bone composition of Ca and P. No significant difference was obtained in feed intake (P > 0.05), however, weight gain, feed conversion ratio, and EPEF showed significant differences (P ˂ 0.05). The results showed that the interaction effect of Ross× SBC₂₅₀ had the highest average daily feed intake during 25 to 42 and 0 to 42 d of age, but Ross×CONT group provided the lowest average daily feed intake (P ˂ 0.05). Furthermore, the Ross×CONT group had the highest average daily gain during 0 to 10, 25 to 42, and 0 to 42 d of age (P < 0.05). The Ross×CONT group also provided the best feed conversion ratio during 0 to 10 d of rearing period compared to other treatments (P < 0.05). Various levels of ACTMS, significantly (P ˂ 0.05) enhanced the antioxidant activity of superoxide dismutase and glutathione peroxidase. No significant differences were obtained in blood parameter (P > 0.05), though, SBC₂₀₀₀ exhibited the greatest numerical phosphorus content. There was no significant impact of strain effects on blood metabolites, however, the Ross strain exhibited higher values. The results indicated that the Arian× SBC₂₅₀ group had the largest tibia diameter which had a significant difference from the Arian×CONT group (P < 0.05). In conclusion, ACTMS inclusion in the ration (either replacement or on top) led to the significant improvement of FCR and ADWG (SBC₂₅₀ as on top) and EPEF (SBC₂₀₀₀ replacement) in the Ross strain and some parameters in Arian strains (mostly numerically).
