Environmental pollution with heavy metals (HMs) is of serious ecological and public health concern worldwide. Mining is one of the main sources of HMs and can impact the environment, species diversity, and human health. This study assessed the value of Spilopelia senegalensis as a biomonitor of environmental contamination with metal(loid)s caused by mining activities. S. senegalensis was collected from a gold mining site and a reference site, and metal(loid)s and biochemical parameters were determined. Lead, cadmium, mercury, vanadium, arsenic, copper, zinc, and iron were significantly increased in the liver, kidney, and lung of S. senegalensis from the mining site. Serum transaminases, alkaline phosphatase, creatinine, and urea were significantly elevated in S. senegalensis from the mining site. Lipid peroxidation and nitric oxide were increased, whereas glutathione and antioxidant enzymes were diminished in the liver and kidney of S. senegalensis from the mining site. In addition, multiple histological alterations were observed in the liver, kidney, and lung of S. senegalensis. In conclusion, mining activities provoke the accumulation of metal(loid)s, oxidative stress, and tissue injury in S. senegalensis. Therefore, S. senegalensis is a valuable biomonitor of environmental pollution caused by mining activities and could be utilized in epidemiological avian studies of human health.

ABSTRACTIn muscle and livers of steers given a diet with sodium monensinate a significant decrease in cadmium content was observed. The concentration of manganese, copper, zinc, lead and iron in the analysed organs varied inconsistently. It seems from the results that, in tissues, monensinate influences the metabolism not only of monovalent cations but of polyvalent cations as well.

Leptin, the product of the ob gene, is secreted mainly in adipose tissue. Due to the associations between plasma leptin concentrations and body fat, leptin could be used as an indicator for the in vivo evaluation of carcass composition in breeding programs. Previous studies showed relation between leptin concentrations and some trace elements, suggesting that they might be mediators of leptin production. The present study was designed to evaluate the effect of single nucleotide polymorphism of the leptin gene on concentration of trace elements in the serum of 58 Czech Pied bulls. Three experimental groups of bulls were formed depending on different leptin genotypes: group CC (n = 28), group CT (n = 21) and group TT (n = 9). In all groups, the age (at a mean age of 240 days) and the body weight (mean 291 ± 11 kg) difference among the chosen animals was non-significant. Blood samples of all bulls in experimental groups were collected from vena jugularis externa between 8.00 and 9.30 h. Concentrations of copper, zinc and iron in the serum of animals were measured. Significantly lower (P < 0.05) zinc concentrations were recorded in bulls of TT group (13.21 ± 1.81 µmol·l-1) compared to CC (20.09 ± 1.11 µmol·l-1) and CT group (19.67 ± 1.45 µmol·l-1). In case of copper and iron concentrations in serum of animals, no differences were recorded between the tested groups. This is the first study of its kind in Czech Pied cattle. Based on our results, we may assume that zinc plays some role in the metabolism of adipose tissue, havings an effect on beef quality.

Trace mineral supplementation of feed rations is commonly achieved by the addition of simple inorganic salts. The bioavailability and hence the performance enhancement achieved by trace mineral supplementation is significantly improved if the metal is added in the form of a peptide complex or chelate. Extracts from the Yucca shidigera plant bind ammonia in-vivo and thus may alter rumen fermentation and in turn milk synthesis. The aim was to determine the effects of a supplement (All-Plex, Alltech Ireland) included at 10g/day, on milk yield, milk composition, somatic cell counts (SCC), reproduction parameters and blood copper, zinc selenium and haemoglobin. The supplement contained proteinated minerals (100mg copper, 300mg zinc, 300mg manganese, 2mg selenium) and a yucca extract (1g Dc-Odorase, Alltech Ireland).
