Serum 25-Hydroxyvitamin-D Concentrations in Beef Cattle Herds in Which Ruptures of the Achilles Tendon Had Occurred
Serumkoncentrationen av 25-hydroxyvitamin-D hos köttdjur i besättningar där rupturer av achillessenan förekommit
Acta Veterinaria Scandinavica volume 26, pages 169–178 (1985)
Abstract
The frequency of skeletal disorders including ruptures of the Achilles tendon has increased during the last years in Swedish beef cattle herds, especially in intensively raised calves. The serum concentrations of 25-hydroxyvitamin-D, calcium and inorganic phosphorus were analysed in 7 affected and 3 control herds. None of the animals in affected herds had detectable amounts of serum-25-OH-D3 (≤ 2 ng/ml) while the control animals had a concentration of 36.1 ng/ml (least squares mean). Calcium and inorganic phosphorus were also significantly lower in the affected herds (P ≤ 0.001). In 1 herd the animals were randomly divided into 4 groups and treated in one of the following ways: Orally with vitamin AD3E or D3, intramuscularly with D2 or D3. The effect of treatment on serum Ca and Pi was measured 1 month later and was found to be equally high in the 4 groups.
Sammanfattning
Frekvensen skelettskador, inkluderande achillessenerupturer, har under de senaste åren ökat i köttdjursbesättningar speciellt hos intensivt uppfödda kalvar. Serumkoncentrationen av 25-hydroxyvitamin-D, kalcium och oorganiskt fosfor mättes i 7 drabbade besättningar och i 3 besättningar utan kliniska symptom. Inte något av djuren i drabbade besättningar hade detekterbara nivåer av serum-25-OH-D3 (≤ 2 ng/ ml) medan kontrolldjuren hade en koncentration på 36.1 ng/ml (least-squares mean). Även kalcium och oorganiskt fosfor var signifikant lägre i de drabbade besättningarna (P ≤ 0.001). I 1 besättning gjordes försök med 4 olika former av D-vitamintillförsel (oral tillförsel av AD3E eller D3, intramuskulär tillförsel av D2 eller D3). Behandlingseffekten på Ga och Pi i serum mätt en månad senare, var densamma i de 4 grupperna, innebärande normaliserade nivåer.
