Hemorrhagic bowel syndrome (HBS), also known as jejunal hematoma or jejunal hemorrhage syndrome, is a sudden death disease primarily of adult dairy cows.

The transition period is a tumultuous period for a cow and those of us trying to manage them. During this time cows are particularly prone to mineral and metabolic imbalances that can leave them more susceptible to diseases as well as lower milk production and poorer reproductive performance.

Selective dry cow therapy (SDCT) is an effective way to use antimicrobials judiciously on dairy farms while decreasing treatment costs and maintaining herd health. In the Netherlands it has been enforced since 2014 and the national somatic cell count (SCC) has decreased.

Since pre-industrial times, global surface temperatures have risen considerably and most of the warming occurred in the past 40 years.

Subclinical hypocalcemia (SCH) is an invisible threat to both the dairy cow and producer. As nearly 45 percent of multiparous cows experience SCH during the early lactation period, producers can implement dietary strategies such as feeding negative dietary cation anion difference (DCAD) rations in the late dry period or administering prophylactic calcium treatments to fresh cows to minimize the risk of SCH.
