Abstract
A method of formulating dairy cow rations based on the amounts of ruminally available protein (RAP) and carbohydrates (RAC) in the total daily ration, which includes both grain and forage components. Quantities necessary for determining RAP and RAC values are obtained from conventional chemical analysis and in situ techniques. Statistical analysis of experimentally obtained data showed optimized lactation response is obtained from a total daily ration containing RAP and RAC in the ranges of about 10.5-12.5% and 35.0-45.0%, respectively. Other important nutritional factors such as microbial synthesis and feed escape protein were also shown to be optimized by total daily rations containing RAP and RAC levels within or near the lactation optimization ranges.
