The environment the cow is in during the transition period is tremendously impactful.
What happens to calves in the last three months before they are born can influence their own lifetime outcomes, and even those of their offspring.
Use of these unique genetic bulls could reintroduce lost genetic variation.
Just because a heifer can get pregnant to calve at 21 months doesn’t necessarily mean she should be bred that early.
Extending the lactation period of high-yielding cows can improve main reproductive measurements, such as fertility.
Veterinarians have at least eight options for doing a cesarean section (c-section) in cattle, but most rely on only one.
Each culling decision should be a bit individualized, based on a heifer's genetic background and health history.
