Transrectal ultrasound examination was performed once in 1159 German Mutton Merino ewes in a standing position using a 5.0 MHz linear array transducer (group 1), 505 German Mutton Merino ewes were restrained in dorsal recumbency while scanned transrectally using a 7.5 MHz probe (group 2). Referring to actual number of lambs born the prepartal prediction of fetal number was correct in 71.8% (group 1) and 78.6% (group 2) of the ewes from days 17 to 69 p.c. The highest accuracy for determining fetal number (89.1%) was in group 1 at days 35 to 46 of gestation. In group 2 the accuracy was more consistent over the whole period of examinations and reached over 80% from as early as 29 days p.c. As litter size increased, examinations in both groups became increasingly inaccurate in determining correct litter size. A subdivision of living, underdeveloped and dead embryos or foetuses was possible by the presence or the absence of a heartbeat and the crown-rump-length of the embryos or foetuses. The percentage of ewes with embryonic or fetal loss is given.

652 bitches suffering from the pyometra-endometritis complex were divided into three groups. General condition and the haemogramm were examined. The bitches of group III (n = 220) had greatest disturbances, and the mortality rate was high, especially in bitches with uterine rupture (50%). The healing rate of 63.7% in this group is the result of a special treatment schedule that is also possible under practical conditions.

This paper reports on a case of hepatozoonosis of a dog imported from Italy to Germany being additionally infected with Ehrlichia canis and Babesia canis. Furthermore, a survey of the epidemiology of the Hepatozoon canis infection is presented.

More and more veterinarians are going to perform laparoscopic diagnosis and surgery those days. But the technique using capnoperitoneum implicates several alterations of different physiological parameters, which, without proper monitoring, are often realized to late. Pathophysiology under CO2 insufflated abdomen as well as counter measures to keep or reestablish physiological situations are described. Within experimental studies, 27 pigs received partial colon resection using the laparoscopic technique, another six after laparotomy. They were compared concerning controlled ventilation, cardiovascular and blood gas parameters as well as the body temperature. Monitoring of the end-exspiratory CO2-gas tension as well as controlled ventilation seems to be essential. Blood gas analyses are proposed additionally. Under the described laparoscopic conditions blood circulation and body temperature seem to be influenced positively.

The topographic-anatomical situation of the conus medullaris and the cauda equina in cats is shown: in about two thirds of the cases the conus medullaris at least reaches the level of the first sacral vertebra. As far as the site of the epidural injection is concerned the sacrococcygeal space or the first intercoccygeal space are proposed in order to avoid damage to the spinal cord. When seeking the site of injection it is advantageous to orientate oneself by following the sacral processus spinosi in caudal direction beginning with the lumbosacral space. In case of adipose animals the first intercoccygeal space can be palpated by moving the tail up and down. Both sites are equivalent. The volume to be injected varies between 0.3 and 0.9 ml solution per cat depending on the needs.

41 heifers of 260-440 kg body weight used in an experiment were polyovulated with PGF2 alpha and PMSG (1000 IU). Animals were slaughtered during luteal phase of ovarian cycle (day 12-15). Shortly before slaughter ovarian structures were defined by rectal palpation und ultrasonographical examination. Post mortem ovaries were collected to compare their structures with previously performed in vivo diagnosis. More follicular structures were detected sonographically (109%) than could be found by morphologic examination (100%). Concerning corpora lutea a right diagnosis was made by palpation in 94% of cases, whereas the rate was only 85% for ultrasonographical examination. Main reasons for false diagnoses of ultrasonographical examination are as follows: multiple ovarian structures, corpora lutea with holes inside, atypical shape of ovaries, atypical ultrasonographical pictures and irregular shape of follicles.

Unlike the situation in humans, it is illegal to administer doping drugs to animals. The Doping Commission of the European Council has defined the term doping. According to this definition, the therapeutic use of drugs is not doping. The treatment of pain is also therapeutic. However, governing bodies of sport can apply stricter regulations (doping lists). It is possible for veterinarians to infringe paragraph 3 (11) of the German animal welfare act if they act recklessly or without due care, and a prosecution may result. It is therefore obligatory for the veterinarian to advise of the possible consequences of administering a drug which has a doping effect, or is included on a doping list.

The study involved 120 cats, of which 60 were treated with Baypamun HK and 60 cats received a preparation of virus free cell culture medium. Therapeutic efficacy was determined by monitoring the general status of health, body weight, skin, lymph nodes, oral cavity, the presence of the p27 antigen and the FeLV p27 antigen concentration in serum. No statistically significant differences between both groups could be demonstrated neither for clinical nor for virologic parameters. Remission of the viremia occurred in 11.7% of the cats treated with Baypamun HK and in 6.7% of the cats treated with placebo. The FeLV p27 antigen level decreased by an average of 7.2% with Baypamun HK and by an average of 5.1% with placebo.
