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

Launch the Feed Library
Aeuromycin 50 Aeuromycin 50
This calculator helps producers figure the amount of Aeuromycin 50 to add to a ration to achieve a desired intake rate, or evaluate a pre-mixed feed to determine intake of CTC.

Launch calculator
BCS Change 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.

Launch calculator
Boom Sprayer Calibration 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.

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

Launch calculator
Bovatec 68 Bovatec 68
This calculator helps producers figure the amount of Bovatec 68 to add to a ration to achieve a desired intake rate, or evaluate a pre-mixed feed to determine intake of lasalocid.

Launch calculator
Breeding Season Breeding Season
4 ratings:
This tool is useful if you know when you will turn out bulls and want to know when to expect calving.

Launch calculator
Calving Season Calving Season
This tool calculates the variables of calving season, such as when to turn the bulls in and out; gestation length is customizable.

Launch calculator
Carrying Capacity Carrying Capacity
3 ratings:
This calculator will allow you to estimate the proper carrying capacity for a desired period of grazing.

Launch calculator
Deer Spotlight Survey Calculator Deer Spotlight Survey Calculator
A tool to interpret data from a deer spotlight survey such as sex ratio, population composition and deer density.

Launch calculator
Drug Withdrawal Drug Withdrawal
This tool calculates when animals are clear for slaughter.

Launch calculator
Dry Fertilizer Dry Fertilizer
5 ratings:
This calculator is for use with soil test results that will allow you to compare prices and furnish spread rates. Enter the price of fertilizer in your area, your acreage and N-P-K needed (from your soil test recommendation).

Launch calculator
Feed Intake 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.

Launch calculator
Fertigation Injection Schedule Fertigation Injection Schedule
This interactive schedule enables a grower to determine the amount of a soluble fertilizer to apply to a selected vegetable crop via the drip irrigation system for any total length of bed (row) at any given week of the growing season.

Launch calculator
Frame Score Frame Score
This calculator helps producers determine the frame score of beef cattle. From frame score, mature weight as well as equivalent steer finished or slaughter weight can be estimated. Frame score and final weight dramatically affect the efficiency of beef production.

Launch calculator
Grazing Cycle 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.

Launch calculator
Hay Days Available 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.

Launch calculator
Heifer Development Heifer Development
This calculator helps determine the ADG required to achieve goals when developing replacement heifers for breeding. Achieving adequate weight at breeding is critical to achieving high conception rates in yearling heifers.

Launch calculator
Lime Calculator Lime Calculator
This calculator figures the amount of lime needed based on soil test report values.

Launch calculator
Net Energy Conversion Net Energy Conversion
This calculator estimates the metabolizable energy, net energy for maintenance, and net energy for gain of a feed if you know the feed's TDN value.

Launch calculator
Orchard Sprayer Calibration Orchard Sprayer Calibration
This calculator determines the gallons per acre applied by an air blast or fan sprayer.

Launch calculator
Payment Calculator Payment Calculator
This tool calculates payments based on the number of pay periods and the total payment of a loan and generates a payment schedule via email.

Launch calculator
Pearson Square 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.

Launch calculator
Pecan Tree Evaluation Pecan Tree Evaluation
The productivity of a pecan orchard is based on many factors, but arguably the most important is the cross-sectional square feet of trunk area per acre. Cross-sectional square feet of trunk area per acre is the sum of the trunk sizes of the trees per acre.

Launch calculator
Protein Supplement 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.

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

Launch calculator
Rumensin 80 Rumensin 80
This calculates levels of monensin and Rumensin 80 to include in rations for cattle.

Launch calculator
Value of Gain 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.
