ABSTRACT

Costs of drugs for pneumoenteritis and plasmosis treatment were evaluated in 614 bucket reared female calves of six Holstein-Friesian (HF) x Guzera crossbred groups (1/4 to > 31/32 HF gene fraction). Important heterosis effects resulted in lowest health costs for F₁ (US$ 4.33 per calf) and highest costs for > 31/32 HF calves (US$ 8.01).

Keywords: comparative; performance; Holstein-Friesian; Guzera; health costs; calves.
