was very sensible when the degradation rate of fiber (B2 carbohydrate fraction) was changed. Table 4. Level of urea nitrogen found in milk (MUN) and MUN levels predicted by the CNCPS model for the various trials conducted in Quilichao, Colombia. Trial Intermediate stocking rate (3 AU/ha) MUN observed MUN predicted + Sugarcane 10 3 + 75% sugarcane + 25% legume 11 3 + 50% sugarcane + 50% legume 14 7 + 25% sugarcane + 75% legume 17 11 Low stocking rate (2 AU/ha) + Sugarcane 8 0 + Sugarcane + legume 12 0 High stocking rate (4 AU/ha) + Sugarcane 6 0 + Sugarcane + legume 12 1 To better understand why the model is not adequately predicting the results of intermediate stocking rate trials, we should have the following additional information: (1) chemical analysis of feed refused (sugarcane + Cratylia) during trials to better predict nutrient pool sizes consumed; (2) body weights at weekly intervals for all trials and treatments to adjust for average tissue mobilized or deposited; (3) biomass availability of B. decumbens after grazing (it was only measured at the beginning of grazing) to estimate growth; (4) estimate of pasture growth by taking forage samples at 2-week intervals, thus simulating cow grazing; (5) weekly milk yield and composition; and (6) body condition of animals. 82
Usefulness of the CNCPS Model The Tropileche Consortium can benefit from a close collaboration with the University of Cornell by developing a broad database on tropical forages and by calibrating the model for tropical conditions. Potential benefits of the CNCPS for Tropileche include: • This tool may help joint efforts to identify alternatives with potential to increase animal productivity by identifying nutritional constraints, for example alternative diets. • It is the basis to evaluate on-farm production systems and propose alternatives to select diets. • It compliments the CIAT farm-level model developed by R.D. Estrada to conduct ex-ante and ex-post analysis at the farm and watershed levels. • It increases Tropileche's menu of options to support and complement the activities of partners and producer organizations, which could finance forage research. • High return on investment because Tropileche will invest marginally to complement more than 10 years of research to develop the CNCPS at its current state. 83
