Foals weaned in the presence of other mares show reduced stress levels and adapt faster to life without their mothers. Weaning methods can significantly impact stress hormone levels in foals, with gradual separation showing less stress than abrupt removal.
Scientists found Asian elephants store thermal reserve by lowering body temperature at night, allowing them to regulate body temperature in hot environments. This mechanism, known as heterothermy, may be more common in mammals than previously thought.
A recent study by Christine Aurich's group at the University of Veterinary Medicine, Vienna found that short-term branding stress levels are comparable to microchip implants in foals. However, branding causes more prolonged tissue damage and alterations in body temperature, leading to increased welfare concerns.
A recent study developed a system to continuously monitor blood glucose levels in diabetic dogs, revealing that none were receiving ideal treatment. The system provided valuable insights for improving treatment plans, including adjusting insulin doses and diets.
A recent study has reclassified cowpox virus into distinct species, challenging the long-held assumption of a single causative agent. The research also found that commercial smallpox vaccines are derived from central or eastern Europe, rather than Jenner's original English strain.
A study of 17 cats with epilepsy revealed that early treatment can lead to improved outcomes and a better quality of life for affected animals. The researchers found changes in the hippocampus similar to those seen in human MTLE-HS, but without structural brain damage.
Researchers found that diarrhoea is closely linked to changes in faecal bacteria, with the majority of foals developing the condition due to colonisation by E. coli and other bacteria. This suggests that horse breeders should not limit suckling time or use supplements to prevent diarrhoea.
Researchers have discovered that subtle genetic changes can significantly impact an organism's size and shape. The study, led by David Stern at Princeton University, found that five specific genetic changes contribute to the evolution of distinct morphologies in fruit flies. These findings provide insight into how individual mutations ...
Researchers discovered c-JUN's ability to prevent methylation of p16INK4a and Cdk6, accelerating tumour formation and stabilizing these genes. This new function reveals a complex role for the protein in cancer development.
A DNA-based test can identify whether a cryptosporidium is of mammalian or snake origin, with prevalence figures revealing widespread infection in popular pets like corn snakes and leopard geckos. Reptile owners must be aware of the risk of cross-species infection and the importance of regular testing to prevent the spread of disease.
Researchers found that female birds choose partners based on their genetic compatibility, specifically high MHC gene diversity, rather than physical attractiveness. This study provides the first experimental evidence for MHC-dependent mate preference in birds.
The €820,000 project aims to enhance the competitiveness of Austrian and Hungarian poultry industries by establishing a knowledge centre. The centre will foster industry activities, improve efficiency and ensure safe poultry production.
The Asiatic wild ass is critically endangered due to habitat destruction and hunting. The species' range is limited to areas with low biomass production, forcing it into unproductive habitats. Conservation efforts could benefit not only the wild ass but also other rare mammals by opening up migration corridors.
Researchers studied fruit flies adapting from sub-Saharan Africa to Europe and found that a gene called crm regulates temperature-dependent traits. The study reveals that changes in this gene may have enabled the flies to survive in colder climates.
Researchers found that alpine marmots increase n-6 polyunsaturated fatty acid concentrations in their cell membranes before hibernation, preparing for low temperatures. This seasonal change is reversed upon hibernation termination and appears to be controlled by an endogenous clock.
A recent European study found that dormice in certain habitats live longer due to fewer predators and successful avoidance methods. The animals' ability to accumulate fat reserves helps them survive harsh winters.
Scientists have developed a mouse with individual genes knocked out only in Natural Killer (NK) cells, allowing them to study the functions of these immune cells in intact organisms. The study reveals that NK cells are essential for the correct development and survival of these cells.
Recent research by Farlow and colleagues reveals a fundamental change in understanding the evolution of DNA, suggesting that DNA repair mechanisms may drive intron variation. The study proposes an alternative explanation for the observed range of intron numbers across species, providing a new perspective on the role of junk DNA.
The orangutan genome sequence provides unique insights into human evolution, revealing genetic similarities with a putative ancestral great ape. The study also highlights the importance of conserving genetic diversity in orangutan populations, particularly for the critically endangered Sumatran species.
A study by Christine Aurich's group found that altrenogest treatment reduces the risk of miscarriage in older, pregnant mares. The treatment has no effect on hormone levels but enables foetuses to recover and grow at a normal rate during critical periods of development.
Recent research reveals significant genetic differences between Asiatic and African cheetah populations, highlighting the need for targeted conservation efforts. The few remaining Asiatic cheetahs in Iran require urgent attention to prevent extinction.

However, exercise and proper training can alleviate stress levels over time. Gentle handling from the start is crucial to develop a strong bond between horse and rider.
Researchers have discovered a new function of interferons, which inhibit the production of IL-1beta protein and suppress inflammation. This finding has significant implications for treating autoimmune and inflammatory diseases.
Researchers at Vetmeduni Vienna identified a novel mechanism by which Mycoplasma agalactiae switches its surface protein genes. The so-called phase variation is caused by alterations in short DNA sequences controlled by an enzyme called recombinase. This process enables the organism to avoid host defense mechanisms during infection.
