Abstract
Statistics for reproduction and lactation traits were estimated from 51,826 records of Alpine, La Mancha, Nubian, Saanen and Toggenburg does. Means and standard deviations varied little across breed or lactation number. Relationships among reproduction and lactation traits were estimated from a subset of 42,618 records with 125 days or more in milk. Correlations also were stable across breed and lactation number. Regression analysis indicated a curvilinear relationship between lactation traits and reproduction traits.
