Elford notes grain is higher in phosphorus, plus this year producers are feeding more green feed or salvage crops that may have got hailed which then are also typically higher in phosphorus.
He says if producers are feeding alternative feeds make sure you’ve done a feed test so you know what you’re feeding and can bump up nutrients as required.
He says it’s very important for animals in the final trimester and after calving.
“About 75% of the growth of that fetus occurs in the third trimester, so there’s a lot of energy and protein that is required for that. There’s generally speaking about a 15% energy requirement during that third trimester for the animal to meet all the needs of that fetus and the momma cow.”
He notes and with the extremely cold temperatures it’s important to get the newborn calves dried off and warm as quickly as possible to avoid hypothermia and frostbite.
