Bull Expense Calculator
Farm Business Management Update, May 2007
By Bill Whittle of the Department of Agricultural and Applied Economics, Virginia Tech
The purpose of the calculator is to assist beef producers in determining actual or expected costs associated with keeping a herd bull for differing numbers of cows. This information will provide a farmer with the basis for comparing the cost/benefit of a purchasing herd bulls at different prices or for comparing the cost/benefit of natural service versus artificial insemination for all or a portion of the cow herd.
The Bull Expense Calculator consists of three sheets: 1) Introduction, 2) Bull Expense Calculator (includes Input Form and Expense/Result Form), and 3) Ration Cost Calculator. The Result Form on the Bull Expense Calculator reports the costs of keeping one bull in three formats:
Inputs are
The input for feed cost per year is determined by using the Ration Cost Calculator. The Ration Cost Calculator allows you to put in the bull’s specific ration, costs of feed stuffs, percent feed wastage, and the length of the feeding period. We recommend that you develop a balanced ration for your herd bulls based on NRC requirements for weight, frame, age, and farm environmental conditions. You can use the Ration Cost Calculator to change
The following example shows the cost for a $1,850 bull with an example set of inputs. The spreadsheet may be obtained by downloading the attachment by selecting this link, Bull Expense Calculator, or by contacting the author.
