Four adult ostriches developed sudden onset paresis and were unable to stand up when disturbed. After treatment with selenium and vitamin E, one of the birds could stand and move normally. The others died and post mortem examination revealed pale patches in the thigh muscles. Histopathological examination showed degeneration of skeletal muscles as seen in nutritional myopathy. Serum selenium and vitamin E levels were low whereas aspartate aminotransferase and creatine kinase levels were very high. All remaining birds on the farm were given multimineral and vitamin E supplement and no more cases were seen.

The following case report describes a selenium toxicosis in a pig-fattening farm of two finisher groups. The diseased animals partly showed ataxia and paresis or intense lameness in connection with band-like ablation of the epidermis at the coronary band. Some of them suffered from alopecia. Foot-and-mouth disease and swine vesicular disease were excluded by serological tests. Dissection revealed a multifocal bilateral symmetric poliomyelomalacia. Histological changes in the claws ranged from severe cell-decay in the germinative layer to distinctive decay of the stratum corneum. Due to damage of the claw epidermis the corium was partly exposed. Feed analysis revealed 100-fold increased selenium content in the finishing premix from the feed mill and as a result 20- to 60-fold increased selenium values in feed samples from the farm-made finisher mixture. Selenium concentration in the blood of diseased animals was 4- to 10-fold higher than normal values, which confirmed the tentative diagnosis of a selenium toxicosis.

Perioperative complications and deaths occurred while developing a novel surgical model of pediatric kyphosis in 10 to 12 kg male farm-raised Yorkshire piglets. All piglets appeared clinically normal preoperatively. Intraoperative complications included tachycardia, respiratory acidosis, and death. Postoperatively, clinical signs included posterior paresis, head pressing, prolonged anesthetic recovery, difficulty rising, and sudden death. Necropsies were performed on all piglets. Some morbidity and mortality were accurately attributed to the spinal surgery. However, the index piglet for this report died suddenly approximately 16 to 18 h after surgery. Necropsy of this animal revealed clear, serosanguineous pleural and pericardial effusions along with myocardial hemorrhage and hepatic lesions, consistent with mulberry heart disease and hepatosis dietetica, respectively. Serum vitamin E and selenium levels from this animal were below age-specific lab reference ranges. Clinical signs of vitamin E and selenium deficiency are most common in fast-growing weaner piglets. The added stress of major surgery may exacerbate the condition in young piglets. Resolution of morbidity and mortality in both juvenile and adult pigs occurred upon the use of an alternate vendor able to provide feed analyses meeting industry standards, although serum levels of vitamin E and selenium in similar ages and breed of swine were still occasionally slightly below reference ranges.
