Serum concentrations of selected minerals in Lika pramenka lambs fed by feed suplemeted with white button mushroom (Agaricus bisporus)

The adequate amounts of essential minerals are critical to maximizing the productivity and health of livestock. It is known that mineral deficiencies can lead to impaired growth and reproduction of animals and increases in disease, due to impaired immune function, and serious deficiencies may even cause death. Mushrooms are an excellent source of many nutrients including minerals, e.g. phosphorus, potassium and calcium but have a low sodium content. The objective of this study was to examine whether the intake of the dry and raw fruiting bodies of white button mushrooms does influence minerals serum concentration in lambs of the Lika Pramenka sheep breed. For this study, 60 clinically healthy, three-month-old lambs (32 females and 28 males), were randomly divided into four groups comprised of 15 lambs each. The first group was a control group in which lambs were fed for six weeks with a standard diet, the second group of lambs was fed for six weeks with commercial lamb food supplemented with 15% of raw Agaricus bisporus the third group was fed for six weeks with commercial lamb food supplemented with 1.5% dried Agaricus bisporus, and the forth group was kept extensively on pasture. Blood samples were taken once, and in the obtained sera calcium, potassium, chloride, sodium and phosphorus concentrations were defeminated by using standard commercial kits Beckman Coulter Biomedical Ltd., O’Callaghan’s Mills, Co. Clare, Ireland on an automatic Beckman Coulter AU 680 analyzer Beckman Coulter Biomedical Ltd, Ireland. Results showed that feed supplemented with Agaricus bisporus mushroom did not have a statistically significant effect on the selected blood minerals concentrations in lambs but also did not have any adverse effect on it. This research was funded by the Croatian Science Foundation with the project "Innovative functional lamb products" (IP-2016-06-3685).
