Management usually leads to smaller calves at birth, it can explain some weak calves, research shows.
“ Good feeding management that provides balanced nutrition to the cow can help prevent weak calves,” Hoppe says.
A study at the University of Idaho found fewer cases of weak calf syndrome when the mothers were fed a higher level of protein 60 days before calving.
The researchers reported that cows receiving lategestation rations with more than 10 percent crude protein had offspring with a 0.6 percent incidence of weak calf syndrome, while cows receiving rations with less than 10 percent crude protein had calves with an 8.5 percent incidence of weak calf syndrome.
Cows with a body condition score of 3 or 4 are more likely to have offspring with weak. calf syndrome than cows with more body fat, Hoppe notes. The lack of body fat isn’ t the only issue involved, although it is a good physical indication.
“ When protein content in feeds is low, it indicates other nutrients also may be less than required,” he adds.“ These nutrients include calcium, phosphorus, copper, zinc and selenium.”
