Accurately quantifying activated immune system energy requirements in vivo is difficult, but a
better understanding may advance strategies to maximize animal productivity. Study …

During the transition period, dairy cows undergo large metabolic adaptations in glucose,
fatty acid, and mineral metabolism to support lactation and avoid metabolic dysfunction. The …

Dairy cows undergo tremendous metabolic and physiological adaptations around parturition
to support lactation. The liver is central to many of these processes, including …

Four multiparous lactating cows (175 to 220 d in milk [DIM]) were used in a 4× 4 Latin
square design to assess the effects of four doses (0.0, 0.5, 1.0, and 1.5 μg/kg of body weight) …

The dry-off of dairy cows represents an important phase of the lactation cycle, influencing the
outcome of the next lactation. Among the physiological changes, the severity of the …
