Keep pre-weaned dairy calves healthy and warm
The pre-weaning period is when calves are highly susceptible to cold stress with a lower critical temperature of 50°F for newborn calves and 32°F for older calves. In other words, calves are very easily stressed right now. Those that experience cold stress will have compromised immune systems, affecting them for life. Tracey Erickson with South Dakota State University … [Read more...]
Study suggests more than half of lameness goes undetected
“Producers are aware of lameness as an issue in dairy herds and almost all monitor lameness as part of their daily routine. However, producers underestimate lameness prevalence, which highlights that lameness detection continues to be difficult in in all housing systems, especially in tie stall herds,” according to researchers who studied dairy farms.
