An online survey of llama and alpaca owners was used to collect data on the population, husbandry, feeding, management measures and health problems. A total of 255 questionnaires were evaluated. In total, 55.1% of the owners had started keeping South American camelids within the last six years. The majority managed small farms with fewer than 15 animals (66.4% of 250 farms). More than half of the participants stated that they kept the camelids as hobby animals (64.3%), although they used them for wool production (55.7%) and/or for breeding (51.8%). Vaccination and deworming were carried out on more than 80% of the farms. The most common diseases occurring on the farms were endo- and ectoparasites. A total of 55.3% of the owners estimated their own knowledge of South American camelids as good, 14.5% as very good. In contrast, more than half of the owners agreed little or not at all with the statement that veterinarians generally have sufficient knowledge about South American camelids. Further research is needed to include veterinarians’ perspectives and thus optimise animal husbandry.

South American camelids (SAC) are being more and more presented at the veterinary Clinics in Germany. A bad nutritional condition, which can be easily categorized using a body condition score (BCS) of the animals, is often not noticed by the owners. Further anaemia is also often only detected in an advanced stage in SAC. Clinical detection of anaemia can be performed by assessing the FAMACHA©-score (FS), that is adapted from small ruminants. So far, there is only little information available about BCS and FS in SAC. In this study, both clinical scores were assessed in alpacas and llamas presented at the veterinary clinic and compared with the haematological parameters from the animals. The data were extracted retrospectively from the animals’ medical records and compared statistically. More than half of the alpacas (60%) and llamas (70%) had a BCS < 3, while 12% of the alpacas and 21% of the llamas had a FS > 2. A decreased BCS was associated with a decrease in haematocrit, haemoglobin, lymphocytes, and eosinophils, as well as an increase in FS and neutrophils. BCS and FS should be assessed regularly in SAC to detect emaciation and anaemia in time.

Gastric ulcers are a common finding in post-mortem examinations of South American camelids (SAC), but diagnosis in living animals is often difficult. The aim of this study was to provide an overview of the incidence of gastric ulcers in alpacas, common concomitant diseases, and clinical as well as laboratory findings to facilitate diagnosis for veterinarians. For this purpose, a total of 187 necropsy reports of alpacas were evaluated, including clinical and laboratory findings on the living animal. A total of 23.5% of the animals (n = 44) were found to have gastric ulcers, nine were perforated. Compartment 3 was most frequently affected by gastric ulcers. No sex predilection could be detected, but animals 1 year of age and older were more frequently affected by gastric ulcers than animals under 1 year of age. Alpacas with gastric ulcers were presented to the clinic due to different non-specific symptoms. In alpacas with gastric ulcers, significantly more organs or organ systems besides the stomach revealed clinical findings than in animals without gastric ulcers. Of the 44 animals with gastric ulcers, a total of 21 alpacas (47.7%) had a poor nutritional status, but cachexia was not significantly more frequent in animals with gastric ulcers than in other dissected animals without ulcers. Hematologic investigations revealed a significantly lower white blood count and significantly lower segmented neutrophils than in deceased animals without ulcers. Compared to animals discharged after treatment, alpacas that died with gastric ulcers had significantly higher levels of band neutrophils and fewer eosinophils and basophils. Occult blood in feces was found in three of 12 animals with gastric ulcers examined for occult blood. In summary, gastric ulcers are a common problem in SAC, which is difficult to diagnose clinically or by laboratory investigations. As these are often chronic processes involving other organ systems, regular monitoring of the animals' nutritional status and early detection of disease symptoms may help to prevent gastric ulcers.

Anaemia is a common finding in South American camelids presented to the veterinary clinic. This report describes the case of a llama presented with general weakness and pale conjunctives, displaying severe anaemia with a Packed Cell Volume (PCV) of 6 per cent and suffering from haemonchosis. The animal was presented in lateral recumbency before being treated with whole blood transfusion. After administering a total volume of 850-ml blood, the clinical condition improved remarkably. Regeneration of the haematological parameters required several weeks, PCV increased from 6 per cent on day 0 to 23 per cent on day 28.

Mastitis is a common economically relevant problem in dairy farming. As the major entry for pathogens is the papillary duct, one of the first defence mechanisms is the teat sphincter. This sphincter shows a rhythmic contractility of yet unknown origin. Searching for possible modulatory pacemaker cells, teat sphincters of eight cows were stained immunohistochemically with antibodies against CD117 and vimentin and evaluated microscopically for the presence of telocytes. CD117- and vimentin-positive telocytes with telopodes were found in close contact with smooth muscle cells. Our findings present a first evidence of telocytes in the teat of bovines.
