Abstract
INTRODUCTION Five cases of ovarian tumors (granulosa cell tumors) in cattle are presented from the patient load of the Vetsuisse University of Zurich and Bern. The aim of this work was to demonstrate the variable development of the illness and to indicate diagnostic and therapeutic possibilities to the practicing veterinarians. Case 1 shows bilateral appearance and the development of malignancy and metastases. The main symptoms in case 2 were the development of the mammary gland in a juvenile animal and the behavior modification due to a hormonal imbalance. The cases 3, 4 and 5 underwent surgery, case 4 restarted reproductive activity resulting in five subsequent pregnancies. The initial presumption is a result of a gynecological including ultrasonographic examination and can be verified by the analysis of Müllerian Inhibiting Hormone in serum. The decision to perform surgery should be done rapidly, as normal fertility can be achieved if the tumor is located unilaterally. Tumor growth and potential malignancy can provoke fatal health issues and also make it impossible to use meat of these animals for consumption.

Abstract
INTRODUCTION The goal of this study was to investigate the hair cortisol concentration (HCC) in healthy and ill cows and their newborn calves. A total of 40 cows and their 42 newborn calves were divided into two groups: group 1 consisted of 19 clinically healthy cows and their 20 newborn calves, and group 2 comprised 21 cows that had had a chronic illness in the third trimester of gestation and their 22 newborn calves. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) system was used to measure the HCC in hair samples that were collected from the cows and calves on the day the calves were born. In both groups, the mean HCCs of the calves was significantly higher than that of the cows (group 1, 31,0 vs. 0,6 pg/mg; group 2, 19,4 vs. 0,8 pg/mg; P.

Abstract
INTRODUCTION Mandibular fractures are among the most common fractures in cattle. The medical records of 108 cattle with a mandibular fracture, that were referred to the University of Zurich Veterinary Hospital from 2005 to 2019, were analysed to document the types of treatment, complications and long-term outcomes. Cattle, still alive at the time of retrospective analysis, underwent clinical and radiographic examinations. A fall was the single most common cause of a mandibular fracture (48,1 %), and a third of all cattle had a concomitant disease at the time of referral. Seventy-five cattle (69,4 %) had a single fracture, 26 (24,1 %) had two fractures and seven (6,5 %) had three fractures of the mandible. The molar part of the mandibular body was most commonly (40,7 %) fractured followed by the diastema (23,6 %), the pars incisiva (13,4 %), the ramus (12,1 %) and the symphysis (10,2 %) of the mandible. The majority of cattle (84/108, 77,8 %) had open fractures. Treatment was instituted in 63/108 animals (58,3 %) with 77/148 fractures. Of these fractures, 28 were treated with plate osteosynthesis, 25 with an external fixator, 8 with cerclage wire, 7 using mixed techniques, 4 with fragment excision, 4 underwent conservative treatment and one a mucosal suture. In total, 45/108 animals (41,7 %) were culled because of multiple fractures, concomitant diseases and because of economic reasons. Complications occurred in 34 (54,0 %) treated cattle; 22 had abnormal wound healing of which 18 developed osteomyelitis complicated by a sequestrum (14). Of the treated 63 cattle, 56 (88,9 %) were discharged. The mean postoperative productive life was 46 ± 29,2 months for animals that were deceased at the time of the study. Thirteen of the cattle with a sequestrum remained in the herd for 15 to 92 months (mean, 47 months) and one for 2 months. The life expectancy after treatment did not differ significantly from that of the Brown Swiss and Swiss Holstein dairy cattle populations, where the cattle of this study mainly came from. Eleven cattle were available for long-term follow-up; all had a good general health status but nine had dental abnormalities including missing teeth, steps or enamel points, which did not noticeably affect the body condition of the animals. Surgical treatment of selected mandibular fractures had a favourable prognosis (52/63 healed, 82,5 %) in cattle.

Abstract
INTRODUCTION Eating and rumination variables were recorded using a pressure sensor integrated into the noseband of a halter in 60 cows with left displaced abomasum (LDA) before and after postoperative administration of flunixin meglumine (FM). Group 1 comprised 9 healthy control cows that were used to establish reference intervals. Group 2 included 60 cows with LDA that received one of the following three treatments: intravenous saline solution (2A, n=20), 1.1 mg/kg FM (2B, n=20) or 2.2 mg/kg FM (2C, n=20) once daily for 3 days after right-flank omentopexy. Median eating times on the day before surgery were 93 (2A), 80 (2B) and 114 (2C) min, which were below the reference interval (246 to 381 min). On the day after surgery, eating times had increased significantly to 201 (2A), 172 (2B) and 216 (2C) min, after which time they continued to increase. Eating and rumination times, numbers of regurgitated feed boluses per day and chewing cycles per bolus did not differ among treated groups. Postoperative administration of FM did not affect eating and rumination variables in this study, and normalisation of these variables was attributable to surgical correction of LDA.

Abstract
During dry season of 2014, some ticks were collected on cattle (Bos taurus and Bos indicus) and grasscutters (Thryonomys swinderianus) in sugar complex areas of Savanna District of Côte-d'Ivoire. Two localities were concerned; SUCAF 1 in Ferkessédougou and SUCAF 2 in Komborodougou. The main objective was to inventory tick species that parasite cattle and grasscutters in this region, then, to identify the shared species between these two groups of animals. To this end, ticks were collected from 70 cattle (35 females and 35 males) and 50 grasscutters (30 females and 20 males). Four tick species were found on cattle: Amblyomma variegatum, Hyalomma truncatum, Rhipicephalus annulatus and Rhipicephalus microplus. On grasscutters, three species of ticks were found: A. variegatum, Ixodes aulacodi and Rhipicephalus simpsoni. The species A. variegatum dominated cattle infestation and was the only tick present in the two groups of animals. But, only immature forms were found on grasscutters. This later specie was mainly infested by adults R. simpsoni.

Abstract
In North Africa, the parasite Echinococcus granulosus is transmitted in a synanthropic cycle evolving mainly between dogs (DH) and sheep (IH), but other animals like cattle are most often found to be more infested with hydatid cysts but their potential role in human contamination via dogs is unknown. The purpose of this study is to assess the prevalence and fertility rates of hydatid cysts in ruminants (cattle and sheep) in two slaughterhouses in central and eastern Algeria. Determining the frequency and fertility of cysts in cattle will assess the degree of involvement of this species, alongside sheep, in the epidemiological cycle of E. granulosus in Algeria. In the present study, prevalence rates were estimated at 4.9% and 10% in slaughtered ruminants, all species combined at the slaughterhouses of El Harrach and Souk Ahras, respectively. The distribution of the prevalence by species indicates higher infestation rates in cattle compared to sheep: 6% vs 3.9% and 37% vs 4.7% in the slaughterhouses of El Harrach and Souk Ahras, respectively. The survey results showed relatively low cyst fertility rates in cattle compared to sheep: 13.8% vs 43.7% and 33.3% vs 71.4% in the two slaughterhouses, El Harrach and Souk Ahras, respectively. The low fertility rate of cysts in cattle can be explained by a poor adaptation of the species, E. granulosus sensu stricto, previously identified by molecular analysis in all samples of hydatid cysts collected from cattle in Algeria. In conclusion, cattle infested with E. granulosus sensu stricto, with low fertility rates, play a minor role in the epidemiology of cystic echinococcosis in Algeria. It is rather an indicator of the persistence of cystic echinococcosis infection in endemic regions.

Abstract
INTRODUCTION Diarrhea in calves is one of the most important cattle diseases in Switzerland. The diagnosis and treatment of calf diarrhea represent a major challenge. Single-celled Cryptosporidium parasites are the most prevalent causative agents of calf diarrhea besides rotavirus in the first weeks of life, and are responsible for about 50% of diarrheal cases. Cryptosporidium parvum has been described as a cause of diarrhea in one to three weeks old calves since the 1970s. Oral ingestion of persistent environmental oocysts results in severe diarrhea lasting four to six days and shedding of large numbers of infectious oocysts. A tiny amount of 10 oocysts is already sufficient to cause disease. Detailed knowledge about the epidemiology and virulence of the different C. parvum strains is still lacking. In addition, current diagnostic tests cannot reliably distinguish between non-pathogenic (e.g. C. bovis) and pathogenic Cryptosporidium species. Until now, no effective therapeutic drug or vaccine against calf cryptosporidiosis has been found. Water-borne epidemics and the zoonotic potential of Cryptosporidium in immunodeficient patients are of great medical importance. The increasing number of cryptosporidiosis cases associated with high infant mortality in less industrialized and impoverished regions (including South-East Asia and sub-Saharan Africa) has intensified the research in recent years. The recent discoveries of new therapeutics against C. parvum may benefit calf medicine in the near future. This review article reports on these new developments, highlights calf cryptosporidiosis in Switzerland and draws attention to a new research project.
