Serum inorganic phosphate, calcium and magnesium levels of cattle in Botswana

Tropical Animal Health and Production Aims and scope Submit manuscript

Summary

Serum inorganic phosphate levels in Botswanan cattle at the end of the dry season were in the low normal range. Levels varied from one area of the country to another and only in some areas were the levels compatible with those seen in aphosphorosis. Levels were lowest in areas with poor grazing but low serum levels were not necessarily associated with clinical signs of aphosphorosis. Bonemeal supplements increased serum inorganic phosphate levels and its effect was most marked when animals had good grazing available.

Résumé

Les taux de phosphate inorganique dans le sérum du bétail du Botswana sont régulièrement faibles à la fin de la saison sèche. Les taux varient d'une zone à l'autre mais ce n'est que dans quelques régions qu'ils sont compatibles avec ceux qui sont observés dans l'aphosphorose. Its sont les plus bas dans les régions à maigre pâturage mais les faibles taux sériques ne sont pas forcément associés à des signes cliniques d'aphosphorose. Des suppléments de farine d'os augmentent les taux sériques et leur effet est le plus net quand les animaux disposent d'un bon pâturage.

Sumario

Los niveles de fosfato inorganico en el suero de ganado en Botswana al final de la estación seca estuvieron en el limite normal inferior. Los niveles variaron de una area a otra y solo en algunas aresa los niveles eran compatibles con aquellos vistos en afosforosis. Los niveles mas bajos fueron vistos en areas de pastoreo pobre pero niveles reducidos en el suero no estaban necesariamente asociados con síntomas clínicos de afosforosis. Suplementos de harina de hueso incrementaron los niveles de fosfato inorganico en el suero y el efecto era mucho mas marcado cuando los animales tenían buena capacidad para el pastoreo.
