Abstract
INTRODUCTION Clinical symptoms are mostly unspecific in hepatic diseases, thus most clinical examinations are of limited benefit in the diagnosis of hepatic diseases and often only general statements can be made about parenchymal damage or loss of function. In contrast, sonography of the liver can provide information about the type of lesion and thus also about the prognosis for the animal. A systematic assessment of organ size, parenchymal, vascular and bile duct system structures can facilitate to make possible findings. Sonography is also used in further diagnostics such as liver biopsy or chole-cystocentesis. This review describes the basic procedure for the sonographic examination in ruminants and camelids on the basis of selected findings relevant to the clinical veterinarian. In addition, potential and limits of additional diagnostics are discussed.

Abstract
INTRODUCTION One of the varied tasks of the Large Animal Rescue Service Switzerland and Liechtenstein (GTRD CH/FL)® is the recovery of animals from manure and cesspools. The aim of the present retrospective study was the evaluation of the rescue protocols of the GTRD CH/FL from such operations and the documentation of a rescue procedure. In the past 25 years, a total of 176 animals have been rescued from manure and cesspools. These included 113 cattle, 51 horses and 12 pigs. All animals could be safely rescued with the animal rescue and transport net (TBTN) or the large animal vertical rescue set (GTVBS). The TBTN is used when the opening of the cesspool is large enough to recover the animal in a horizontal position. The GTVBS is particularly suitable for narrow openings, as the recovery in a -vertical position does not require any constructional modification or the enlargement of the cesspool opening. Both rescue harnesses are characterized by reliable handling and allow gentle recovery.

Abstract
INTRODUCTION Introduction The impact of lameness on milk yield in dairy cows has been investigated already in many countries by several authors, taking into consideration almost exclusively locomotion scores ≥ 3. The aim of this study was to evaluate the impact of lameness and of the various lameness scores (2-5) on milk yield and milk solids in cows of the three most important dairy cattle breeds (Fleckvieh, Braunvieh, Holstein-Friesian) in Austria within one lactation period. Material and methods Locomotion scoring of dairy cows was performed by trained personnel every 30-40 days in 2014 during the course of routine performance testing. From the recorded locomotion scores (1-5) and the number of lameness episodes, the cows were classified into five lactation-locomotion-score-groups (LLS-G1-5). In total, data sets of 4005 cows from 144 dairy farms across Austria could be evaluated. Using two statistical models the fixed effects on LLS group, breed (evaluation across all breeds in model 1), farm, year and season of calving, parity and the «continuous effect» number of milking days were included in the analyses of milk, fat and protein yield. Results The mean, cumulative lameness prevalence during the observation period was 51.0%, and 8.1% were cows from the LLS-G5 group showing repeated and severe locomotion scores. During the first 100 days in milk 34.7% of all cows were lame. In model 1, all effects considered had a significant impact (P .

Abstract
INTRODUCTION The modern technique of cattle hoof care was founded by E. Toussaint Raven in 1977. Environmental risk factors on cattle claws altered in the past 43 years. The change from free ranging to indoor housing, the intensified feeding and the breeding towards traits of high performance have significantly increased the mechanical and chemical stress on the claws. In modern free-stalls, dairy cows are required to walk on hard flooring to feed, drink and get milked. Good hoof health is a basic requirement for cattle welfare. Professional and regular hoof trimming is still considered the most effective measure to promote hoof health in dairy cattle. In order to meet today's requirements and to promote claw health, the Swiss Hoof Trimmers Association (SKV), in collaboration with the Vetsuisse faculties, Universities of Berne and Zurich, and the Bovine Health Service (RGD, Bern) developed and described the Swiss technique of functional claw trimming. The aim was to establish a consistent method, which takes into account the size and bodyweight of the modern cow, the anatomical and physiological characteristics of their claws and includes adaptations counteracting very relevant diseases such as digital dermatitis. The result is a workflow described and illustrated with coloured pictures and consisting of five individual steps based on the technique of E. Toussaint Raven, Additionally, the upcoming Swiss national resource project on long-term improvement of claw health is presented in some detail. The key point of this project is the electronic documentation of clinical findings by the trained professional claw trimmers. This data will later (i) be used to assess the foot health of Swiss cows, (ii) allow to determine the prevalence of foot diseases of cattle in Switzerland and (iii) to monitor the effect of the implementation of foot health concepts. The aim of this work is to combine the findings from science and the practical experience of hoof trimmers in one method, to standardize the applied hoof care in Switzerland and to adapt it to today's hoof health requirements.

Abstract
INTRODUCTION This study included 94 cows aged 2.1 to 12.0 years (5.2 ± 2.05 years) that were examined at a referral clinic because of type-1 abomasal ulcer. The most common clinical findings were poor general health status (94%), partial or complete anorexia (93%), congested scleral vessels (89%), decreased skin surface temperature (76%), decreased or absent faecal output (72%), abdominal guarding (59%), tachypnoea (56%), rumen atony (53%) and positive percussion and simultaneous auscultation and/or ballottement and simultaneous auscultation on the right side (53%). The most common laboratory findings were hypokalaemia (68%), positive base excess (60%) and azotaemia (51%). The chloride concentration of rumen fluid was increased in 48% of the cows. The diagnosis of type-1 ulcer was made during laparotomy and/or postmortem examination. One or more concurrent diseases were diagnosed in 97% of the cows. Seventy-eight (83%) cows were euthanased immediately after the initial examination, during laparotomy or after unsuccessful treatment, and eight (8.5%) cows died, and all were examined postmortem. Eight (8.5%) cows were discharged and six of these made a complete recovery.

Abstract
INTRODUCTION The aim of this study was to evaluate the duration of estrus suppression after a double administration of the anti-GnRH vaccine Improvac® (Zoetis Schweiz GmbH, 2800 Delémont) in cows. Furthermore, it should be investigated, if a third administration could prolong the effect of the cycle suppression. A total of 21 cows (more than four weeks post partum) were vaccinated twice, at least 35 days apart, with 2 ml Improvac® (0.4 mg of a GnRH-analogon) subcutaneously on one side of the neck. Over a period of 368 days and in the course of 18 farm visits these cows were examined gynecologically and re-vaccinated if they showed signs of estrus behaviour or ovarian activity. After the second vaccination the cycle of the cows was suppressed for an average period of 114 days (59-175 days) and the effect could be prolonged by a booster of the vaccine for another 127 days in three cows. Estrus behaviour was absent for a longer period than ovarian activity was. The vaccine was tolerated well: apart from slight swelling at the injection site, no side effects were observed. Our results demonstrate that two immunizations with Improvac® are an easily applicable method for the suppression of cyclic activity in cows for a mean period of 114 days. The duration of cycle suppression was prolonged by a booster of the vaccination.

Abstract
INTRODUCTION A manuscript from 1748 in Rhaeto-Romanic language is discussed. It's an unfinished translation of a publication in German language from 1715 which contains elements from the standard work on household and agriculture by Johannes Coler, 1645. By comparing the manuscript with 15 contemporary publications and manuscripts from Switzerland, textual similarities were found in three publications. The manuscript contains 62 therapy instructions for cattle diseases and 7 for pig diseases. Remedies of plant origin, food of animal origin and faeces are applied. Various interventions lead to painful injuries of the animals. Most therapies have to be considered as irrational.

Abstract
INTRODUCTION Good quality colostrum intake is essential for passive immunity in neonatal calf and foals. The quality of colostrum depends on its IgG content. Since in practice the possibilities for a direct determination of these parameter are limited, an estimation of colostrum quality is often based on its biophysical properties. The simple methodology allows to perform measurements directly on site and immediately after birth. The biophysical properties included in the current review are density, refractive index, relative density, viscosity, pH, and color. The determination of the density of bovine colostrum is a common method for the evaluation of the IgG content in practice since it correlates with IgG. Density of bovine colostrum should be 1047 g/l. Different colostrometers are available for the measurement. This method is also used in the horses. Density of equine colostrum should be 1060 g/l. Refractive index or the relative density by refractometer has been proven to correlate with the IgG and is an established method in cattle and horses. Good bovine colostrum should have an index of 22% brix and equine colostrum 23% brix. Although not yet established in practice an additional methodology would be the determination viscosity of bovine colostrum. Viscosity could be measured with an outlet cup. A relationship between viscosity and IgG has demonstrated. Sufficient data for this method is missing for equine colostrum. Color and pH are not suitable for estimating the IgG content.

Abstract
INTRODUCTION The objective of the present study was to investigate reliability of transrectal three-dimensional ultrasound (3D-S) for antral follicle count (AFC) in dairy cows. Furthermore individual differences of AFC between cows and the fluctuation of AFC within and between different cycles were evaluated. To test the reliability of 3D-S, AFC was determined on the ovaries of 10 cows in vivo and compared with counts obtained after slaughter using computer tomography. To evaluate cyclic follicle dynamics, six cows were repeatedly examined with 3D-S over a period of two cycles. Using 3D-S, follicles with a mean diameter greater than 2 mm could be recorded. AFC determined with 3D-S and computer tomography showed a significant correlation (r ≥ 0.86, p < 0.05) and values were similar (p ≥ 0.05). AFC differed between individuals (p < 0.0001) and a moderate fluctuation within and between two cycles within the same cow was apparent (p < 0.05). In conclusion, 3D-S is a suitable method for determination of AFC in cattle. AFC differs between cows and cyclic fluctuations are apparent in a lesser extent.
