The influence of the Covid-19 pandemic on municipal meeting places arranging group exercise for older persons.

Purpose: Many municipalities today, together with other stakeholders, offer group exercises for the older population via municipal meeting places, focusing on promoting good health. During the Covid-19 pandemic, these group exercises either continued in a modified form or ceased. The aim of this study was to explore involved stakeholders' experiences of group exercises for older persons arranged via municipal meeting places during the Covid-19 pandemic.

Colostrum and milk selenium, antioxidative capacity and immune status of dairy cows fed sodium selenite or selenium yeast.

Dietary selenium (Se) can be supplemented from organic or inorganic sources and this may affect Se metabolism and functional outcome such as antioxidative status and immune functions in dairy cows. A feeding trial was performed with 16 Holstein-Friesian dairy cows fed with a total mixed ration (0.18 mg Se/kg dry matter (DM)) either without Se supplement (Control, n = 5), or with Se from sodium selenite (Group SeS, n = 5) or Se yeast (Group SeY, n = 6).

The role of dietary selenium in bovine mammary gland health and immune function.

Mastitis is not only a major cause of economic losses to the dairy industry but also a major problem in ensuring the quality and safety of the milk, associated with high somatic cell counts and residues of antibiotics used for treatment. One innovative approach to protection against mastitis is to stimulate the animal's natural defense mechanisms. Technological advances in immunological research have increased our ability to exploit the immunity of the bovine mammary gland during periods of high susceptibility to disease.
