Merck Animal Health, a division of Merck & Co, agreed to acquire Vence, a virtual fencing company for rotational grazing and livestock management. Financial terms were not disclosed. “The acquisition of Vence will broaden our portfolio with complementary products and technologies to advance animal health and well-being as well as outcomes for our customers. Vence is a natural fit with Merck Animal Health’s growing portfolio of animal intelligence products that include identification, traceability and monitoring products. This new technology will give cow-calf producers the ability to track their cattle and the ability to move them from pasture to pasture,” Rick DeLuca, Merck Animal Health President.
