bacteria, somatic cells, treatments
Under the current component pricing system dairy producers are paid by the amount of components (protein, butterfat, other solids) that end up in their milk tanks every day. On top of these, premiums increase their gross revenue, which include over-order premiums, quality premiums, and volume premiums. Quality premiums are paid to encourage producers to supply high quality milk and vary depending on the individual processor. Although quality premiums might sometimes seem small, we usually fail to understand that high somatic cell counts (SCC) are closely associated with milk production loss and thus milk volume premiums. Concentration of components, total milk shipped, and milk quality as represented by SCC and bacteria counts are among the things producers can control.
