The high value of milk protein, increasing feed costs, and growing concerns for the environment have made nitrogen (N) utilization a central component in balancing dairy cow rations. The objectives of this thesis were to evaluate field usable tools to predict N utilization and excretion and help develop protocols to improve N utilization on commercial farms. Specifically this included (1) an assessment of the daily variation in bulk tank milk urea nitrogen (MUN), (2) a computer-based evaluation of the Cornell Net Carbohydrate and Protein System's (CNCPS) ability to predict N excretion, and (3) a farm level evaluation of the ability of the updated CNCPS (v6.1) to develop rations with less environmental impact. In the first study, two data sets (Set A and Set B) containing daily bulk tank (BT) MUN concentrations from commercial farms were obtained from a local cooperative. Milk urea N values were analyzed by source (Set A and B) and by farm (n = 787 and 601 for Set A and B, respectively) across three months (Jan, Feb and March). Mean MUN values from Set A and B followed a normal distribution with the greatest proportion of farms (45% and 42%, respectively) falling within the 11-13 mg/dl range. The majority of variation in both data sets was explained by variability among farms. However, ~10% was attributed to the effect of month while ~20% was unexplained. The unexplained variation could be due to differences in sampling time or technique at the BT, number of milkings, total milk in the BT and/or laboratory error. Significant differences (P

We can only control what we can measure. In the case of dairy farming, nitrogen utilisation requires a higher level of control to reduce environmental pollution and improve farm economics. Nitrogen metabolism in the ruminant animal is a complicated system and accurate evaluation of protein utilisation by dairy cows is limited by current methods. This dissertation assesses various methods of analysing ruminal crude protein degradation and introduces a new method of assessing protein value of forages i.e. the protein available to the ruminant for absorption at the duodenum. The following procedures are included: in situ incubation, Cornell Net Carbohydrate and Protein System, in vitro enzymatic degradation and the modified Hohenheim gas test. The third section of this dissertation applies these methods to a controlled experiment investigating the effect of wilting on the protein value, protein characteristics and amino acid profile of grass silage. Conclusively, the results of this study aid in estimating protein supply from forages to dairy cows.

The need to reduce nitrogen (N) and phosphorus (P) losses as well as the (direct and indirect) use of fossil energy on intensive dairy farms in Europe to ecologically acceptable levels requires radical changes of the management of these farms. The objective of the project, (started in 1993) was to develop sustainable dairy farming systems with minimum inputs and losses of nitrogen phosphorus and energy.
