Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 613-624, September 2026.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 658-666, September 2026.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.

VRK1‐Related Motor Neuropathy With Upper Motor Neuron Signs and Selective Muscle Involvement

Journal of the Peripheral Nervous System, Volume 31, Issue 3, September 2026.
ABSTRACT Introduction Hereditary motor neuropathies (HMN) represent a heterogeneous group of disorders with wide clinical and genetic variability. Despite advances in molecular diagnostics, approximately 50% of cases remain genetically unresolved, particularly those where distinguishing length‐dependent motor neuropathy from motor neuron disorder with ...

Divergent Perceptions of Dairy Farmers on the Role of Grazing in Animal Welfare and Production

Rural Sociology, Volume 91, Issue 3, September 2026.
ABSTRACT The modernization of dairy production, characterized by a transition to freestall barns with automatic milking systems and increasing herd sizes, has resulted in a decline in cattle grazing. The once‐traditional practice of summer grazing in Northern Europe has become a contentious topic, with the industry and public holding divergent views ...

Comparative analysis of microRNAs in bovine colostrum and neonatal calf blood

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5799-5809, 15 August 2026.
Abstract BACKGROUND MicroRNAs (miRNAs) are short non‐coding RNAs that participate in a wide range of biological processes. MiRNAs are present in high concentrations in colostrum, and these may be potentially transferred to newborn calves being fed colostrum.
