Article Synopsis
- The study involved 190 non-lactating, pregnant beef cows that were tested on different mineral supplements (sulfate vs. organic-complexed) to evaluate their impact on various health and production metrics.
- While no significant treatment effects were observed on cow body condition scores, differences in body weights and liver mineral concentrations were recorded at various stages during gestation and after calving.
- Notably, cows receiving the organic complex supplement showed higher expression of a specific liver gene related to mineral metabolism compared to those receiving the sulfate supplement.
One hundred and ninety nonlactating, pregnant beef cows (¾ Bos taurus and ¼ Bos indicus; 138 multiparous and 52 primiparous) were assigned to this experiment at 117 ± 2.2 d of gestation (day 0). Cows were ranked by parity, pregnancy type (artificial insemination = 102, natural service = 88), body weight (BW) and body condition score, and assigned to receive a supplement containing: (1) sulfate sources of Cu, Co, Mn, and Zn (INR; n = 95) or (2) an organic complexed source of Cu, Mn, Co, and Zn (AAC; Availa4; Zinpro Corporation, Eden Prairie, MN; n = 95).
