Cows affected by mastitis caused by Klebsiella (K.) pneumoniae often become seriously ill. In some cases herdproblems may occur. Contaminated bedding material is considered to be one of the most common risk factors for klebsiella mastitis. In a recently performed study in USA it was found, however, that more than 80 % of healthy, lactating dairy cows excreted K. pneumoniae in faeces.

The purpose of this study was to examine vitamin A and E in equine nutrition and especially in relation to forages. A literature review was conducted to examine factors that influence the level of vitamins present in forage, the vitamin A and E requirement of horses, and the absorption of vitamin A and E in horses. The influence of DM level on alpha-tocopherol and beta-carotene content in ensiled forage was investigated in a controlled ensiling study using baled silage and haylage. The results from the ensiling study were combined with data of vitamin A and E concentrations collected from literature. Calculations were done to theoretically establish how well the vitamin content in ensiled forage can cover the maintenance requirements of vitamin A and E in horses.

SummaryAt the start of my employment at the Swedish National social insurance office I was a bit confused because there were two categories which I defined as belonging to the same category (working handicapped) but it wasn?t so. The persons I where going to meet was defined as having incapacity to work and therefore, they were defined as not standing to the labour markets conversion.

Q-feber är en endemisk zoonossjukdom som förekommer i hela världen med undantag av Nya Zeeland. Sjukdomen orsakas av den gramnegativa intracellulära bakterien Coxiella burnetii som är mycket motståndskraftig i miljön och kan spridas i aerosoler via vind och damm. Flera olika djurslag kan drabbas av Q-feber men nötkreatur, får och getter samt husdjur som hund och katt är de främsta källorna till humana infektioner. C. burnetii kan hos djur ge upphov till reproduktionsstörningar som t.ex.

At seed-growing the aim is to produce a commodity with high germination capacity, good soundness and purity, and also slight admixture of seeds from other species. The capacity of germination and the vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases, growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can be due to the fact that the seeds are in rest of germination, i.e.
