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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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

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.
