Penelitian bertujuan untuk mengetahui nilai pertumbuhan alami (natural increase) sapi potong dan faktor-faktor yang mempengaruhinya di Kecamatan Pangkalan Lada Kabupaten Kotawaringin Barat. Penelitian ini bersifat deskriptif analitik dengan penentuan responden berdasarkan purposive sampling. Jumlah sampel yang digunakan dalam penelitian adalah 178 responden dari 10 desa dengan total populasi sapi potong 713 ekor terdiri atas 3 (tiga) bangsa sapi yaitu sapi Bali (457 ekor), sapi Limosin (151 ekor) dan sapi Simental (105 ekor). Peubah yang diamati meliputi karakteristik peternak dan usaha peternakan, struktur populasi sapi potong, dinamika populasi sapi potong dan natural increase. Hasil penelitian menunjukkan struktur populasi sapi potong berdasarkan umur di Kecamatan Pangkalan Lada sebagai berikut: pedet jantan (6,45%), pedet betina (13,88%), jantan muda (4,07%), betina muda (10,80%), jantan dewasa (22,30%) dan betina dewasa (42,50%). Calf crop sapi potong (65,91%) sedangkan rasio sex sapi potong jantan banding betina adalah (31,72% : 68,28%). Persentase kelahiran sapi potong terhadap induk (65,91%); Persentase kelahiran sapi potong terhadap sampel (21,64%). Persentase kematian sapi potong (1,34%). Persentase natural increase sapi sapi potong di Kecamatan Pangkalan Lada (20,30%). Kesimpulannya struktur populasi sapi potong di Kecamatan Pangkalan Lada didominasi oleh jantan dan betina dewasa. Natural increase sapi potong di Kecamatan Pangkalan Lada tergolong rendah, sedangkan faktor-faktor yang berpengaruh terhadap natural increase adalah tingkat kelahiran rendah, tingkat kematian tinggi dan populasi betina dewasa produktif rendah.
