[Lactational incidences of common diseases in dairy herds in Schleswig-Holstein (Germany): effect of first test-day milk yield, herd milk yield and number of lactation].

It was the aim of this study to record common diseases in dairy cows in Schleswig-Holstein, Germany, and to describe associations between lactation number (LN: 1, 2, > 2), first test-day milk yield (TD1: < 30 kg, ≥ 30 kg) and herd milk yield (HM: ≤ 7500 kg, > 7500 kg), the latter parameter serving as a proxy for herd management (extensive vs. intensive). Data of 98 dairy herds (6439 lactations) were processed on cow level using mixed logistic regression models with LN< TD1, HM and calving season as fixed effects and herd as random effect.

A study of the test of supervisory skills.

Subjects (N=2406), workers and applicants of both sexes, were recruited from multiple sources, tested, and the data analyzed to evaluate the usefulness of the test in human resource management applications.
