Drought Information: Calculators

BCS Change

This calculator will help producers understand how much weight cows need to gain or lose to move from their current body condition score (BCS) to a desired BCS. Typically, producers will want to calve their cows in a BCS of 5.5 or higher.

Boom Sprayer Calibration

This calculator determines gallons per acre applied by boom sprayer. These sprayers are suitable for pre-plant, pre-emergence or post-emergence applications in cropland, pastures and rangeland.

Boomless Sprayer Calibration

This calculator determines the gallons per acre applied by a broadcast sprayer equipped boomless or brush type nozzles.

Carrying Capacity

This calculator will allow you to estimate the proper carrying capacity for a desired period of grazing.

Feed Intake

This tool calculates the dry matter intake of an animal. It also calculates the actual amount to feed if you know the desired dry matter intake and content of the feed.

Feed Library

The feed library was created to assist livestock producers in finding and researching feed ingredient options for use in their operations.

Grazing Cycle

This calculator will allow you to estimate the number of days to graze a pasture for a desired grazing cycle. It is simply a measure of forage supply relative to the entire grazing unit. To be used if you are attempting to estimate the grazing period of a known grazing cycle.

Hay Days Available

This calculator allows cooperators to inventory hay supplies on hand and predict the number of days available for either limit feeding or full feeding hay. The cooperator can also use this to back calculate hay demand.

Hay Hauling

The hay hauling calculator allows you to estimate the total cost of purchasing and transporting hay. Users have the flexibility to calculate total cost per bale or total cost per ton. Users can also specify the number of bales able to be hauled per load.

Hay Ring Waste Calculator

This calculator will allow you to determine the amount of hay that is wasted cattle from various hay ring feeder types on a per bale, monthly and annual basis. Additionally, by including the cost of a bale of hay and how many bales are typically fed in a month, the calculator will determine the total cost of the wasted hay to evaluate if the purchase of a more efficient feeder is plausible.

Pearson Square

This calculator is used to balance rations. Two ingredients of known nutrient content, crude protein for example, are input. The desired nutrient content of the blend is entered, and the percentage of each ingredient (on a dry matter basis) needed to create the desired blend is calculated.

Planter Calibration

This tool calculates the approximate number of seeds per acre and number of pounds per acre that a planter is set to deliver.

Protein Supplement

Many times cows will need a protein supplement during the winter feeding period. The most important thing to do, the producer must determine the price per pound of available crude protein for each option. The producer should then select the most economical supplement. Labor considerations can also be factored.

Reserve Herd Days

This calculator will allow you to estimate the days available for grazing in a pasture.

Value of Gain

This tool calculates the value of the gain of an animal. Supplement conversion calculates the cost on a per lb of additional gain basis of using a feed supplement.

Value of Weathered Hay

This calculator enables the producer to determine the actual value of hay in a round bale after taking into account the depth of weathered hay that is low quality and inedible. An additional use of this tool is to determine the additional amount of hay that is required by the cow herd to meet intake requirements, accounting for weathered hay.
