In summer 2025, Feedworks Australia’s Dr. Stephanie Sammes shared Calmin heat stress data with us. Now, it’s published: Calmin supported feed intake, gastrointestinal health, and metabolic resilience during and after heat stress. Read about its potential as a rumen-buffering and protective additive under periods of heat stress. In this issue, we also summarize: chitosan-based nanoparticles (CNPs) neutralizing LPS-induced toxicity in rats; whether supplementing beef steers grazing endophyte-infected (E+) tall fescue with isoflavones from red clover hay could improve growth and reduce post-graze recovery from fescue toxicosis; how postpartum changes in calcium (Ca) and other minerals could help identify endometritis early in dairy cows; the effects of broccoli extract supplementation on growth performance, carcass traits, rumen microbiota, blood metabolites, and gene expression in Holstein steers; how prepartum vitamin D₃ supplementation affects placental gene expression related to calcium metabolism, immunity, and reproduction in dairy cows during the early postpartum period; and the effects of supplementing diets of growing calves and heifers with bee pollen (BP). All that and more at the link below.
