ABSTRACT

In ten cows ten stenotic teats were endoscopically examined and treated. For this purpose two different methods were performed: Either the endoscopy was performed through the teat canal or through a small incision in the side of the teat. The endoscopy through the teat canal proved to be a simple and practical method. However, the results were not always clear-cut, and a controlled operation was not possible. Endoscopy through a side access is more expensive but has several advantages. It allows a good view on the Fürstenbergsche Rosette, one of the most frequent locations of stenosis. Additionally, controlled operations of the level of the Fürstenbergsche Rosette are possible once a suitable instrument has been introduced through the teat canal. The additional trauma caused by the access hole is a minor problem. All cows examined and treated by this method could be milked without any problems three days after the operation.

ABSTRACT

Blood samples were taken from 58 high-performance cows earmarked as donors for embryo transfer, one day before artificial insemination and following superovulation. An evaluation of 16 major indices showed the yield of transferable embryos to be clearly reduced by hypocholesterolemia, hyperproteinemia, and even more by hypophosphatemia. More than one deviating metabolic findings were obtained only from few animals which had the desired high number of embryos, that is above seven.
