Which common EPD relates to the dam's ability to provide nutrition to offspring?

• A. Weaning Weight
• B. Maternal milk
• C. Birth Weight
• D. Yearling Weight

Answer: (B)

In this context, the trait reflects the dam’s genetic ability to provide nutrition to her offspring through lactation. The Maternal Milk EPD estimates how much and how well a dam can feed her calves after birth, which directly influences their growth before weaning. Birth weight is about prenatal size, and yearling weight and weaning weight describe growth outcomes but are not specific measures of the dam’s milk-producing capacity. Calves’ weaning weight is affected by many factors, but the one that isolates the dam’s nutritional contribution during nursing is the maternal milk EPD.
