| Response rates are one indicator of a survey's data quality, as a great deal of importance has been placed on the mail survey's response rate. However, a telephone survey's response rate usually is not reported. Even if one is reported, the numbers used in the calculation are rarely defined making the response rate interpretation unclear. Using a recent telephone survey of Pennsylvania dairy managers, this paper demonstrates how telephone survey data should be reported. Essentially, every research report should include a discussion of how the survey was conducted, a disposition table, and well-defined formulas used to calculate response rates. |

| In 1989, The Cornell Program on Dairy Markets and Policy collaborated with the Texas A&M Agricultural and Food Policy Center to form a National Institute for Livestock and Dairy Policy (NILDP). The Institute is a focal point for a neutral and objective analyses of the consequences of alternative government policies on the livestock, dairy, and poultry industries and the broader economics of livestock and dairy markets. Based on their respective strengths and emphases, Texas A&M is the lead institution on livestock and poultry sector analysis, and Cornell is the lead institution on dairy sector analysis. The Institute has been supported by a special research grant through the U. S. Department of Agriculture since 1989. The Dairy Farm Analysis... |

| This study evaluated the impacts of bST on the profitability of representative Pennsylvania dairy farms using a stochastic simulation model under two initial milk yield-per-cow levels, three levels of milk response to bST, and three milk price forecast scenarios. Results showed that farm profitability was improved with bST, but the magnitude of the benefits from bST depended on the farm's initial milk output per cow and the level of milk response to bST, both of which are related to quality of management. However, modest price declines due to bST-induced increases in the milk supply would have an offsetting effect on farm profitability. |
