A study was conducted to evaluate the effects of dietary inorganic and organic trace minerals in two levels of supplementation regarding performance, diarrhea occurrence, hematological parameters, fecal mineral excretion and mineral retention in metacarpals and liver of weanling pigs. Seventy piglets weaned at 21 days of age with an average initial body weight of 6.70 ± 0.38 kg were allotted in five treatments: control diet (no added trace mineral premix); 50% ITMP (control diet with inorganic trace mineral premix supplying only 50% of trace mineral requirements); 50% OTMP (control diet with organic trace mineral premix supplying only 50% of trace mineral requirements); 100% ITMP (control diet with inorganic trace mineral premix supplying 100% of trace mineral requirements); and 100% OTMP (control diet with organic trace mineral premix supplying 100% of trace mineral requirements). Feed intake and daily weight gain were not affected by treatments, however, piglets supplemented by trace minerals presented better gain:feed ratio. No differences were observed at calcium, phosphorus, potassium, magnesium, sodium and sulfur excreted in feces per kilogram of feed intake. Treatments did not affect calcium, phosphorus, magnesium, sulfur and iron content in metacarpals. Trace mineral supplementation, regardless of level and source, improved the performance of piglets.

Abstract The objective of this experiment was to determine the effects of 4 levels of trace mineral supplementation on feedlot cattle. Two hundred and forty Angus crossbred steers (n = 48, BW = 291 ± 27 kg) were stratified by arrival BW and source and randomly assigned to 1 of 4 experimental treatments in a randomized complete block design (12 pens/ treatment; 5 steers/pen). Cattle went through a 35 d depletion period prior to the administration of treatments where cattle received a supplement that included zero trace minerals and was formulated to meet or exceed other nutrient requirements not met by the ration. Cattle were administered treatments after transition to the finishing ration. The treatments included a negative control (CON) which contained no added trace minerals, a requirement treatment (1X) in which cattle received added trace minerals at requirement levels indicated by NASEM (Co 0.15 mg/kg, Cu 10 mg/kg, Fe 50 mg/kg, I 0.5 mg/kg, Mn 20 mg/kg, Se 0.1 mg/kg, Zn 30 mg/kg; NASEM 2016), a 2 times requirement levels (2X) treatment, and a treatment at four times requirement (4X) levels recommended by the NASEM. Iron was kept constant at 50 mg/kg for 1X, 2X, and 4X treatments. Due to feeding laws, Selenium was included at 0.1, 0.2, and 0.3 mg/kg for 1X, 2X, and 4X respectively. Treatment levels were chosen based on the 2015 Feedlot Consulting Nutritionist Survey. There was no difference in BW, ADG, overall DMI and G:F over the course of the experiment (Linear P ≥ 0.12; Quadratic P ≥ 0.17; CON vs Supplements P ≥ 0.47) There was no difference in marbling score, yield grade, back fat, REA, HCW, or dressing percentage between treatments (Linear P ≥ 0.23; Quadratic P ≥ 0.36; CON vs Supplements P ≥ 0.30). In conclusion, the lack of or addition of supplemented trace minerals at or above indicated requirement levels has no effect on cattle performance or carcass characteristics.
