Regulated handlers are required to submit to the Market Administrator the amounts of producer milk, in pounds, that were received in the previous month. Receipts of Producer Milk is the amount of milk received by producers who meet the requirements of qualification as defined by the statute. This milk is also known as eligible milk for market wide pooling. Each order has its own criteria for pool qualification and for regulated handlers. Regulated handlers, under certain circumstances and price relationships, may elect to not include certain quantities of producer milk that is eligible to be pooled on Federal Orders.

The monthly Uniform Milk Price is derived by multiplying the minimum price for each class by the amounts of milk pooled in each class (this is the pool milk value for each class) and then dividing the aggregated combined pool milk value by the total amount of milk pooled each month. For those Orders that do not utilize multiple component pricing, additional data values (Uniform Butter Price & Uniform Skim Milk Price) are published. For the Orders that do utilize multiple component pricing, the Uniform Producer Price Differential (PPD) is also published. The All Markets Combined is a weighted average of all of the Orders but is based on the Order’s total producer milk pounds at the Order’s Uniform price.

Receipts of Producer Milk by Regulated Handlers is the amount of producer milk in pounds that qualifies for pooling on each of the Federal Milk Marketing Orders each month. Each order has its own criteria that determines if a producer's milk is eligible to be pooled. Average Daily Delivery of Milk Per Producer to Regulated Handlers is the amount of producer milk pooled under each Federal Milk Marketing Order divided by the number of producers whose milk is pooled for that month for each Order and then divided by the number of days in the month. Butterfat Test of Producer Milk is the average percentage of butterfat contained in the producer milk pooled each month. Nonfat Solids Test of Producer Milk is the average percentage of nonfat solids (all milk solids other than butterfat) contained in the producer milk pooled each month. Protein (True) Test of Producer Milk is the average percentage of protein (true) contained in the producer milk pooled each month. Other Solids Test of Producer Milk is the average percentage of other solids (other than butterfat and protein (true). Nonfat Solids, Protein and Other Solids Test Data are only reported for those Federal Milk Marketing Orders that utilize multiple component pricing. Somatic Cell Count of Producer Milk is the average number of somatic cells per milliliter contained in the producer milk reported for those orders who utilize somatic cell counts in their milk pricing formulas.

Starting with October 2020, the Total Receipts of Producer Milk by Order report will be split into two separate monthly reports:

• Producer Milk Components by Order
• Producer Receipts by Order

The Utilization of Producer Milk in Class IV Products is the monthly volume of milk used to produce Class IV Fluid Milk products. The Class IV Utilization Percentage of Producer Milk is the monthly volume of Class IV Milk used to produce Class IV products in each individual order divided by the monthly total of all producer milk pooled for that individual order for all classes. The Butterfat Test of Producer Milk Used in Class IV Products is the percentage of butterfat found in Class IV milk for each order for each month. The Nonfat Solids Test of Producer Milk Used in Class IV Products is the percentage of nonfat solids found in Class IV milk for each order for each month.

The Utilization of Producer Milk in Class III Products is the monthly volume of milk used to produce Class III Fluid Milk products. The Class III Utilization Percentage of Producer Milk is the monthly volume of Class III Milk used to produce Class III products in each individual order divided by the monthly total of all producer milk pooled for that individual order for all classes. The Butterfat Test of Producer Milk Used in Class III Products is the percentage of butterfat found in Class III milk for each order for each month. The Protein Test of Producer Milk Used in Class III Products is the percentage of protein found in Class III milk for each order for each month. The Other Solids Test of Producer Milk Used in Class III Products is the percentage of Other Solids found in Class III milk for each order for each month.

Market information and data is collected throughout the course of the live auction, as the reporter will grade the livestock and record the pertinent information in the reporting tool. Information that the reporter must record for each lot includes the official USDA grade, weight, head count, and selling price. To ensure the accuracy of these reports, each Market Reporter is required to take a written test and apply their skills during an official live animal grading correlation with their supervisor every two years.
