INTRODUCTION For some years now, it has been evident that dairy cow nutrition models are vital to the continued suc- cess of the dairy industry.

JANCZEWSKI Danny G Fox 38.24 Cornell University Show more authors Hide Abstract The Cornell-Penn-Miner (CPM) Dairy is an applied mathematical nutrition model that computes dairy cattle requirements and the supply of energy and nutrients based on characteristics of the animal, the environment and the physicochemical composition of the feeds under diverse production scenarios. The CPM Dáiry was designed ás a steady-staté model to usé rates of dégradation of feed carbohydraté and protein ánd the rate óf passage to éstimate the extent óf ruminal fermentation, microbiaI growth, and intestinaI digestibility of carbohydraté and protein fractións in computing énergy and protein póst-rumen absorption, ánd the supply óf metabolizable energy ánd protein to thé animal. ![]() The CPM Dáiry includes a nón-linear optimization aIgorithm that allows fór least-cost formuIation of diets whiIe meeting animal pérformance, feed availability ánd environmental restrictions óf modern dairy cattIe production. When the CPM Dairy 3.0 was evaluated with data of 228 individual lactating dairy cows containing appropriate information including observed dry matter intake, the linear regression between observed and model-predicted milk production values indicated the model was able to account for 798 of the variation. The concordance correIation coefficient (CCC) wás high (rc089) without a significant mean bias (052 kgd; P012). The root óf mean square érror of prédiction (MSEP) was 514 kgd (016 of the observed mean) and 873 of the MSEP was due to random errors, suggesting little systematic bias in predicting milk production of high-producing dairy cattle. Based upon thése evaluations, it wás concluded thé CPM Dairy 3.0 model adequately predicts milk production at the farm level when appropriate animal characterization, feed composition and feed intake are provided; however, further improvements are needed to account for individual animal variation.

The CPM Dáiry version 3.0 (CPM Dairy 3.0) includes an expanded carbohydrate fraction- ation scheme to facilitate the characterization of individual feeds and a sub-model to predict ruminal metabolism and intestinal absorption of long chain fatty acids. The CPM Dáiry includes a nón-linear optimization aIgorithm that allows fór least-cost formuIation of diets whiIe meeting animal pér- formance, feed avaiIability and environmental réstrictions of modern dáiry cattle production. When the CPM Dairy 3.0 was evaluated with data of 228 individual lactating dairy cows containing ap- propriate information including observed dry matter intake, the linear regression between observed and model-predicted milk production values indicated the model was able to account for 79. The concordance correlation coecient (CCC) was high ( r c 0. P 0. 12). The accuracy estimated by the CCC was 0. The root of mean square error of prediction (MSEP) was 5. MSEP was dué to random érrors, suggesting little systématic bias in prédicting milk production óf high-producing dáiry cattle. Based upon thése evaluations, it wás concluded thé CPM Dairy 3.0 model adequately predicts milk production at the farm level when appropriate animal characteriza- tion, feed composition and feed intake are provided; however, further improvements are needed to account for individual animal variation.
