Winter Nutrition For Your Cattle Herd
Carter: “In general a cow’s nutrient requirements will increase 1 percent for every degree below 20 degrees Fahrenheit as the temperature declines. So if the temperature is 15 degrees than the cow’s nutrient needs increase by 5 percent.”
There are several factors to taken into consideration. Carter continues
Carter: “Temperature at that cattle are comfortable and not expending extra energy really depends on wind speed, whether their skin is wet, whether there is mud on the skin, and the humidity that the cattle live in. So as winter upon us, and we hit strings of cold weather — period of two weeks below zero or down in the teens — you really need to think about how that will affect a cow’s need for nutrient and for protein.”
So that translate to feeding a good quality alfalfa hay — for every six degree below 20 colder — each cow will need an additional pound of hay. Also need to take into account if it is wet or if there is wind as well.
