Effects of Calving Season on Stocker and Feedlot Performance
Abstract In environments where cool-season forages are the major forage resource, shifting calving season from winter to spring may match up forage nutrient supply with animal nutrient demands and thereby reduce purchased feed cost. However, calf BW at weaning in the fall may be less.

Diagnosis of bacteraemia in neonatal foals using 16S rRNA high‐throughput sequencing
Abstract Background Sepsis is an important cause of morbidity and mortality in foals. Early diagnosis can improve outcome but is complicated by non‐specific clinical signs and delayed confirmation of infection via blood culture. Molecular assays represent a rapid and more sensitive alternative.
