Economic evaluation of estrous synchronization programs on Northern Range cow-calf operations

TL;DRAbstract

Estrous synchronization protocols are used to manipulate the estrous cycles of beef cows in order to make artificial insemination easier to apply.Several studies have characterized protocols with respect to pregnancy rate, cost, and labor demand; however, few reports have studied the effects of estrous synchronization programs on enterprise profitability.Therefore, the objectives of this research were to: 1) evaluate the effects of estrous synchronization programs on enterprise profitability in Northern Range cow-calf operations and 2) identify optimum protocols and specific management decisions, if any exist.Also, because a computer model of range beef production capable of simulating the numerous variables related to estrous synchronization programs, a third objective was to develop a simulation model with these capabilities.The model accounted for a variety physiological and economic parameters.Special variables to mimic the effects of estrous synchronization were probability of res
