Gastroschisis‐Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives
Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.A gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.

Journal of Animal Breeding and Genetics, Volume 143, Issue 6, Page 774-783, November 2026.ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...
