Genetic architecture of swine inflammation and necrosis syndrome and its genetic correlation with repeated skin damage scores Open
Lesions and injuries to the extremities of the pig’s body parts, like the tail and ears, are often associated with biting. However, lesion signs observed at birth and in 3-d-old piglets suggest that injuries may also result from swine infl…

Phenotypic and genetic relationships among anogenital distance, anti-Müllerian hormone, and in vitro embryo production in Gyr dairy cattle Open
Anti-Müllerian hormone (AMH) concentration and number of recovered oocytes (ROOC) are phenotypic parameters associated with in vitro embryo production (IVEP). More recently, anogenital distance (AGD) has been proposed as a proxy for fertil…
