This photo shows a Holstein heifer calf receiving a double dose of CalfPerk, an oral caffeine treatment, by a research technician this past month. This study is being held at Walker Farms in Aylmer, Ont and focuses on calf health and vigour for up to 4 weeks of age. The calf is happy to receive its dose, as this oral treatment is a 'sweet' smelling cinnamon paste (CalfPerk is seen on the tubes).
