The use of weekly pasture cover measurements have been shown useful in New Zealand dairies to estimate daily growth rates, determine grazing rotation, calculate feed inventories and they have been used for feed budgeting. The objectives of this study were to take weekly pasture growth measurements to estimate growth and utilization and to learn how to use this information to make management decisions on Oregon dairies. Additionally, all conserved feed fed was recorded daily and milk solids shipped were recorded and these data were used to estimate the percentage of milk produced from pasture. This study was done on one dairy for a 3-year period. Pastures were measured and mapped and total standing DM was estimated weekly in 22 pastures using a calibrated rising plate meter. Paddocks grazed and residual pasture covers were recorded daily and forage cover measurements were entered into management software. Paddock grazing and residual heights were also included in the electronic recordkeeping. Measurements started in March and continued until the end of November for all 3 years. Weekly grazing wedges were developed and were used to make grazing decisions that week. Estimated dry matter yields for all paddocks each year averaged 18695 ± 3451, 17848 ± 3966 and 17306 ± 5058 kg/ha for each consecutive year. Daily pasture DM growth averaged 47, 49 and 56 kg/ha per day for each of the growing seasons. During year 1 the dairy averaged 1219 kg of milk solids per hectare from grass, 888 kg milk solids for year 2 and 962 kg of milk solids per hectare in year 3. Pasture accounted for 85, 72, and 80% of the total DM consumed on the dairy during the 9 mo grazing season for year 1, 2, and 3, respectively.
