A lot of unanswered questions in that write-up
How many cows have calves?
Calf rate survival?
Range condition ?
Those would be high on my list of top questions . that would give a clue to the base problem . Then figure out how to change the basic problem .
That's what the article was talking about. Pregnancy rates appear to be normal. Winter survival is not. That can indicate poor habitat. Or calves being born too late in the year. Or predators killing calves when they're still neonates.
