  <abstract type="Summary">Milchleistung, Fruchtbarkeit der Färsen und Eutergesundheit von F1-Kreuzungen aus Schwedisch Rotbuntem Rind und Deutschen Holsteins (DH) liegen im Bereich von reinrassigen DH, F1-Kreuzungen aus DH mit Montbéliarde, Brown Swiss und Jersey sind dagegen unterlegen. 3-Rassen-Kreuzungen können DH in Fruchtbarkeit und Eutergesundheit ebenbürtig sein, in der Milchleistung liegen sie jedoch deutlich darunter. Fitness und Fruchtbarkeit von Milchrindherden können nur mit F1-Tieren verbessert werden. &lt;ger&gt;</abstract>
  <abstract type="Summary">Milk yield, heifer fertility and udder health of F1 crosses between Swedish Red and German Holsteins (GH) are in the range of purebred GH, whereas F1 crosses between GH and Montbéliarde, Brown Swiss and Jersey are inferior. 3-breed crosses can be equal to GH in fertility and udder health, but they are significantly lower in milk yield. The fitness and fertility of dairy herds can only be improved with F1 animals. &lt;eng&gt;</abstract>
