![]() ![]() While these changes are difficult to accurately include in a computer program, top-notch nutritionists who understand and pay attention to cows can use qualitative knowledge to optimize nutrition.Īllen recommends three rations-fresh, high and maintenance. In addition, cows’ metabolic priorities change throughout lactation. Stage of lactation, parity, milk yield, DMI, body condition and genetic potential all affect cow response. Not all cows respond the same to a ration. Routine feed testing, monitoring variation in feeds, making sure feed mixing is accurate and uniform, ensuring that cows have access to feed most of the day and communicating with managers, feeders and cropping personnel are all important. ![]() Test forages and byproduct feeds for macro and micro minerals to better formulate mineral supplements.Īllen encourages nutritionists and producers to spend more time on activities that can help achieve their goals. Silages and wet feeds should be tested for dry matter content at least twice weekly and for CP and NDF twice monthly until the extent of variation is understood. Each lot of purchased or harvested feed that might be variable should be tested for crude protein (CP) and neutral detergent fiber (NDF). Forages and some byproduct feeds have great variation in nutrient composition while other feeds such as dry corn and high protein soybean meal are more consistent. Strive to increase the consistency of rations by reducing variation in feeds. ![]()
