Effects of different mineral supplementationEffects of different mineral supplementationprograms on beef cattle serum Se, Zn, Cu,Mn concentration, health, growth performanceand meat quality

  • Riferimento: Large Animal Review 2020; 26: 57-64
  • Abstract: The effects of different mineral sources (organic vs inorganic) on beef cattle serum Se, Zn, Cu, Mn concentration, health, growth performance and meat quality (hot carcass weight, dressing percentage, conformation score, fattening score and pH) were assessed in 156 intact Charolaise males. The aim of the study was to investigate a possible ameliorative action of the organic sources of those minerals compared to the inorganic ones, essential for animal welfare and productivity. The animals were allotted to three treatment groups, receiving different sources (organic or inorganic) of minerals at different levels. H-In group received a mineral supplementation from an inorganic source according to the average mineral inclusion recommended by the European beef system. The TRT group received an organic source of minerals at the doses recommended by the producer (TRT, Total Replacement Technology, Alltech). The In group received minerals from an inorganic source, but following the same doses employed in the TRT group. Growth performance and health status were monitored throughout the fattening period (186 days). Blood samples were evaluated in relation to mineral serum concentrations, antioxidant status and immunity reactions. After slaughtering, carcass characteristics and meat quality of Longissimus dorsi samples were evaluated. Growth performance and health status were improved in the TRT group (P<0.05). The incidence of Bovine Respiratory Disease was also lower in this group. The animals in the TRT group had a better immune response (P<0.05) due to the higher circulating mineral concentrations which positively affected the immune function. In addition, carcass characteristics were positively affected in the TRT group because of the enhanced myogenesis (P<0.05). Meat quality was improved in the TRT group due to the higher level of antioxidants in the meat (P<0.05). The results suggest that organic sources have a strong impact on animals’ metabolism and immune function, which led to an improvement in growth performance, health and antioxidant status together with carcass and meat quality.
