Abstract
Associations among six primipara type traits and first and second lactation milk yield, yield persistency, and culling rates were estimated by means of 100 progeny groups with first and 76 with second lactations. Correlations of second lactation culling rate with dairy character and with rear udder were approximately −.4. Persistency, measured in either first or second lactation, was negatively associated with all type traits.
