A cause of Bovine Spongiform Encephalopathy (BSE) related to the feeding of meat and bone meal (MBM) to British cows can be ruled out based on known circumstances Hlásný, J. Private veterinary surgeon, retired Abstract Research into the development of bovine spongiform encephalopathy (BSE) in Britain was not led from the outset by a nutritionist bu...

Purpose From the literature it is known that in British cows at 80s a higher incidence of subclinical (chronic), hypomagnesaemia was found and a new BSE disease appeared. After 1993 began to significantly reduce the incidence of the BSE. The aim of this study was to determine what changes in the period about 1985- 1995 (magnesium content in feed co...

Purpose Epidemiological incidence of neurodegenerative diseases in a certain period, was detected only in cattle in the UK, as the BSE. The official statement about the ca 5-years incubation period of the BSE is based on the feed ban (1988) of meat and bone meal (MBM) in the UK cattle, and the BSE incidence significantly decreased(after 1993). Mat...

Prion diseases, also called transmissible spongiform encephalopathies (TSEs), are a group of fatal neurodegenerative disorders affecting animals (BSE, scrapie…) and humans (CJD…). Until recently, TSEs encapsulated a distinct category of neurodegenerative disorder, exclusive in their defining characteristic of infectivity (prion diseases). It now ap...

In Britain, perennial ryegrass mostly fed (1980s); protein content reached to over 300 g /kg dry matter in young, heavily with nitrogen fertilized grasses (high protein, potassium content); conditions for chronic hypomagnesemia (see; England - Wales; highest BSE incidence; rainy, cool weather and ryegrass - low magnesium content- feeding in high pr...

Epidemiological incidence of neurodegenerative diseases in a certain period, was only detected in cattle in the UK (BSE). This happened at a time, after significant increase of crude protein, in dairy rations (ARC, 1980) in the mid of 1980s, without equality of dietary Mg-supplementation. Feeding readily fermentable young grass (there especially mo...

Neurodegenerative diseases, including BSE, Alzheimer's disease etc. are caused by different mechanisms but may share a final common pathway to neuronal injury due to the overstimulation of glutamate receptors, especially of the N-methyl-D-aspartate (NMDA) receptor subtype. It is generally accepted that the influx of Ca2+ as a result of excessive ac...

A total of 260 tons of a new mineral feed supplement [MKP-C(P)] was used on farms in the Písek district. In the period from January to April, 1988, the mortality of calves decreased by 2.9% in comparison with the same period of 1987 when the Polymin Z or MKP-C supplements had been used. The MKP-C(P) supplement, containing 8 to 10% calcium, 3 to 4%...
