Penelitian dilaksanakan mulai bulan April sampai Juni 2016. Penelitian dilakukan dengan metode survei meliputi 3 desa yaitu Balecatur, Ambarketawang, dan Nogotirto, mencakup 337 peternak sebagai responden. Variabel yang diamati meliputi identitas responden, kepemilikan ternak, struktur populasi, kinerja reproduksi ternak, kematian dan mutasi sapi potong. Data hasil penelitian ditabulasi dengan menggunakan program computer Microsoft Excel kemudian dianalisis untuk menghitung rata-rata dan standar deviasi. Hasil penelitian didapatkan bahwa komposisi sapi potong di Kecamatan Gamping terdiri dari sapi PO 28,71%, SimPO 50,84% dan LimPO 20,45%. Persentase induk terhadap populasi rata-rata 50,95% (PO 39,86%, SimPO 58,69%, LimPO 49,00%). Induk pertama kali beranak rata-rata 30,49±1,23 bulan (PO 29,11 bulan, SimPO 31,48 bulan, LimPO 30,89 bulan), service per conception rata-rata 1,86±0,22 kali (PO 1,61 kali, SimPO 1,93 kali, LimPO 2,03 kali). Tingkat kelahiran terhadap seluruh populasi rata-rata sapi potong diperoleh rata-rata 25,15% (sapi PO 20,28%, SimPO 30,86% dan LimPO 19,00%). Angka kematian terhadap seluruh populasi sapi potong diperoleh rata-rata 0,21% (sapi PO 0,70%, SimPO 0,00% dan LimPO 0,00%).
