Dairy Cattle Nutrition

Evaluating and balancing dairy rations requires computer models. CPM- Dairy (Cornell-Penn-Miner) is used to evaluate and formulate dairy rations based on standards and equations found in the Dairy Cattle NRC (National Research Council) and CNCPS (Cornell Net Carbohydrate and Protein System). CPM-Dairy in a spreadsheet version will be used to describe nutrient requirements, utilization of nutrients for maintenance and milk production, considering environmental impacts and imbalances of carbohydrate and protein fractions in the rumen will be demonstrated. The dynamics of rumen fermentation and the end products of VFA’s and microbial protein will be illustrated in terms of how they affect energy and protein supply to the cow. "Hands on Computer Sessions" will lead participants through the ration formulation process using farm examples. 4 Credit Hours
