Kalsium dan fosfor merupakan unsur makromineral esensial yang sangat dibutuhkan untuk fisiologis ternak. Penelitian ini bertujuan untuk mengevaluasi status kalsium dan fosfor pada sapi potong laktasi di wilayah Nglipar, Gunungkidul. Sepuluh (10) ekor sapi potong digunakan dalam penelitian ini yang terdiri dari kelompok sapi non-laktasi (5 ekor) dan kelompok sapi laktasi (5 ekor). Setiap sapi diambil sampel darah sebanyak 5 mL melalui vena jugularis. Sampel darah yang diperoleh kemudian di sentrifugasi selama 10 menit dengan kecepatan 8000 rpm. Kalsium dan fosfor dianalisis di laboratorium komersial menggunakan Cobas ® c 501, Roche Diagnostics Ltd., Switzerland. Hasil pemeriksaan kadar kalsium pada sapi non-laktasi dan sapi laktasi yaitu 10,22 + 0,28 mg/dl dan 10,20 + 1,02 mg/dl. Kadar fosfor sapi non-laktasi dan sapi laktasi yaitu 3,54 + 0,74 mg/dl dan 6,06 + 1,06 mg/dl. Secara statistik kadar kalsium tidak terdapat perbedaan signifikan (P>0,05), sedangkan kadar fosfor terdapat perbedaan yang signifikan (P<0,05). Berdasarkan hasil penelitian ini disimpulkan bahwa kelompok sapi non-laktasi mengalami hipofosfatemia dengan imbangan Ca : P (2,4-2,8) : 1.

Calcium and phosphorus are essential macrominerals and hold such an important role in physiological processes in animals. This study was conducted to evaluate calcium and phosphorus on lactation beef cattle in Nglipar, Gunungkidul. Ten beef cattles were involved in this study, which divided into 5 non-lactating and 5 lactating cows. As much as 5 mL blood were taken from jugular vein as the sample. All blood samples were centrifuged at 8000 rpm for 10 min. Calcium and phosphorus serum were analyzed using Cobas ® c 501, Roche Diagnostics Ltd., Switzerland. Result from serum calcium analyzed on non-lactating and lactating cows were normal 10,22 + 0,28 mg/dl and 10,20 + 1,02 mg/dl. Phorsporus serum level in non-lactating cows 3,54 + 0,74 mg/dl and lactating cows was 6,06 + 1,06 mg/dl. There was no significant difference on serum calcium of non-lactating and lactating cows (P<0,05), meanwhile serum phosphorus there was significant difference between non-lactating cow and lactating cow. Based on the result of this study, it was concluded that non-lactating cows occur hypofosfatemia with ratio Ca : P (2,4-2,8 : 1).
