| Popis: | ABSTRACT: A promising strategy to improve newborn calf survival could be the administration of nonsteroidal antiinflammatory drugs (NSAID) especially in cases of low vitality calves born from difficult calvings. The objective of this clinical trial was to determine the effect of a single-dose meloxicam treatment [target dosage = 0.5 mg/kg ad usum veterinarium (A.U.V.) injection] on parameters of lying behavior of Holstein-Friesian dairy calves (n = 180) born to eutocic (n = 98) compared with dystocic dams (n = 82). Animal-based measures included newborn calf vitality (low, 1–6 scores; normal, 7–12 scores, scored immediately after birth), calf sex and birth weight, parity of the dam, and early maternal behavior (the time spent licking the calf). Parameters of the complex lying behavior were recorded during the first 48 h after delivery and included (1) the time spent standing, (2) lying down frequency, (3) the longest standing bout, (4) the average duration of standing bouts, (5) the first successful standing, and (6) the first attempt to stand. None of the parameters related to lying behavior were influenced by the parity of the dam, calf sex, or birth weight and maternal grooming behavior. The latency and the first attempt to stand were not influenced by the NSAID treatment; however, the time spent standing, the longest standing bout, and the average duration of standing indicated increased standing ability of meloxicam-treated calves with low vitality, but not in normal-vitality calves. The latency to stand and first attempt to stand were both increased by dystocia. Based on the present findings, sensory measurement of parameters of lying behavior during the immediate neonatal period might be useful to evaluate the efficiency of NSAID protocols. A single-dose meloxicam treatment showed considerable promise for improving standing ability of low-vitality calves. |
