What is the EPD that estimates the milking ability of a bull's daughters?

The estimate that assesses the milking ability of a bull's daughters is known as Maternal Milk EPD (Expected Progeny Difference). This measure evaluates the amount of milk a bull's female offspring are expected to produce, contributing to both the growth and overall health of the calves.

This is particularly important in livestock production as it directly affects the productivity of the herd. A higher Maternal Milk EPD indicates that the daughters are more likely to produce a greater volume of milk, which in turn supports better calf growth rates and overall herd performance.

The other choices pertain to different performance traits: Yearling Weight focuses on the weight of animals at one year of age, Weaning Weight measures the weight of calves at weaning, and Scrotal Circumference helps in assessing fertility in bulls. These traits are valuable in their own right but do not specifically relate to the milking ability of a bull’s daughters.
