ABSTRAK

Penelitian ini bertujuan untuk mengetahui kadar kalsium dan fosfor darah sapi perah FH (Friesian Holstein) pada masa pertumbuhan. Penelitian ini menggunakan sampel serum dari dua puluh lima ekor sapi perah sehat secara klinis yang dibagi menjadi lima kelompok. Masing-masing kelompok terdiri atas lima ekor sapi perah yang dibedakan berdasarkan umur, yaitu satu bulan, tiga bulan, enam bulan, sembilan bulan, dan duabelas bulan. Pengambilan darah dilakukan melalui vena jugularis, kadar kalsium dan fosfor darah diperiksa dari serum menggunakan spektrofotometer. Hasil pemeriksaan memperlihatkan bahwa kadar kalsium berkisar antara 7,5±0,38 sampai 8,7±0,07 mg/dl. Kadar kalsium darah paling tinggi diperoleh dari sapi perah yang berumur tiga bulan. Kadar fosfor darah berkisar antara 3,3±1,15 sampai 6,5±1,75 mg/dl. Kadar fosfor darah paling tinggi diperoleh dari sapi perah yang berumur enam bulan. Kadar kalsium dan fosfor darah yang paling rendah diperoleh dari sapi perah yang berumur sembilan bulan.

Kata kunci: kalsium, fosfor, sapi perah

ABSTRACT

The aim of this study was to know the profile of calcium and phosphorus in blood of FH (Friesian Holstein) dairy cow during growth. Twenty five serum samples were collected from healthy dairy cows that divided into five groups. Each group consisted of five dairy cows are differentiated by age, one month, three months, six months, nine months, and twelve months. Blood sampels were taken from the jugular vein, calcium and phosporus of the serum were examined using spectrophotometry. The results showed levels of calcium in blood of dairy cow ranging from 7,5±0,38 to 8,7±0,07 mg/dl. The highest calcium of blood levels was obtained from dairy cows at age three months. Levels of phosphorus in blood of dairy cow ranging from 3,3±1,15 to 6,5±1,75 mg/dl. The highest of phosphorus blood levels was obtained from dairy cows at age six months. The lowest of calcium and phosphorus blood levels was obtained from dairy cows at age nine months.
