“…However, both the inorganic Zn chloride hydroxide and the organic Zn methionine dose-dependently increased the Zn concentrations in the mane hair of the horses and ponies of the present investigation. Our previous data could partly demonstrate divergent compound effects of these Zn supplements on the fecal microbiota [28] and the immune system [50] of the animals. These results might indicate a different intestinal absorption and metabolic utilization of Zn chloride hydroxide and Zn methionine in equines [28].…”

Little is known about the animal- and diet-related factors that could interfere with the plasma zinc (Zn) concentrations of equines. Additionally, the adequacy of plasma to reflect changes in the Zn intake is unclear. In the first part of this study, the plasma Zn concentrations of hospitalized horses and ponies (n = 538) were measured and evaluated for the impact of the age, sex, horse type, and internal diseases of the animals. In the second part, the effects of increasing dietary Zn chloride hydroxide and Zn methionine supplementations were assessed on the plasma and mane hair Zn concentrations of healthy horses (n = 2) and ponies (n = 8). Part 1: The age, sex, and horse type did not influence the plasma Zn concentrations. No effect of internal diseases was observed, with the exception of higher plasma Zn concentrations in animals with metabolic disorders compared to the control group (p < 0.05). Part 2: Both Zn supplements dose-dependently increased the Zn concentrations in the mane hair (p = 0.003), but not in the plasma of the horses and ponies. In conclusion, the plasma Zn concentrations were widely unaffected by nutritional and non-nutritional factors in equines, while mane hair samples better reflected the dietary Zn supply.

The liver plays a crucial role in metabolism, detoxification and nutrient storage. The liver's response to insult is often non-specific, with inflammation and subsequent fibrosis being the key pathological consequences. The treatment of liver disease is guided by clinical signs and biopsy findings. The aims of therapy are to support the recovery of the liver, treat the clinical signs (if present) and treat the cause of liver disease (if known). Corticosteroids are recommended first-line anti-inflammatory agents, and treatment is continued until biochemical evidence of improvement of hepatopathy is observed. Hepatic support supplements are commonly used but evidence of efficacy is lacking. This review outlines current treatment methods for hepatic disease and liver failure.
