Fiber osteodystrophy (nutritional secondary hyperthyroidism) is an uncommon and poorly investigated disease of horses, connected with diet mistakes and secondary hormonal disturbances. The aim of this study was to asses selected biochemical parameters before and after the treatment of advanced forms of this illness. Horses from the control (healthy) and experimental groups were at the same age and originated from the same area. The affected horses were fed with fodder rich in phosphorus (oats). The horses of the control group were fed with corn mix, carrots, and sugar beets, and had free access to a saline lick. The clinical signs were big head symptoms, painfulness of cranial bones (especially the jaw bone), breathing problems, and joint pain in the extremities. P concentration in blood was statistically significantly lower, Ca and Mg concentrations were within the lowest physiological norms, and there was a significant increase in AST, AP and GGTP activity. After treatment, P concentration in blood increased statistically significantly, and hepatic indicators were slightly improved. The clinical symptoms remained unchanged.

The study group consisted of 60 Holstein-Friesian cattle from farms situated in the central part of the Lublin region in Poland. The cows were kept in a tethered system and fed a TMR or a PMR. It was found that the animals had reduced concentrations of serum macroelements in the puerperal period. Therefore, the amount of a prophylactic mineral additive was increased by 50%. The study was conducted 6-8 weeks after parturition and directly before the dry period. The aim was to determine the influence of the increased doses of the mineral additive on the contents of calcium, phosphorus, and magnesium in serum, as well on the functions of parenchymal organs, to assess the health status of the herd. The results showed that an increased amount of supplements may lead to elevated values of the above macroelements (even higher than physiological standards) in many cows in the herd, which can be particularly dangerous in the absence of regular monitoring of blood biochemical parameters. Moreover, lower conception rates, problems with the musculoskeletal system, and further disorders in the puerperal period have also been reported.
