%X Tujuan penelitian adalah untuk mengetahui status reproduksi, nilai NI, NRR dan output bangsa-bangsa sapi pedaging di Desa Sriwedari Kecamatan Tegineneng Kabupaten Pesawaran, Provinsi Lampung.  Penelitian dilakukan selama dua bulan, dimulai Agustus sampai dengan September 2015. Penelitian dilakukan dengan metode survei terhadap seluruh peternak tradisional yang ada di Desa Sriwedari. Hasil penelitian menunjukkan bahwa struktur populasi sapi di Desa Sriwedari terdiri dari 123 unit ternak (UT) sapi Peranakan Ongole (PO), 57,50 UT sapi Peranakan Limousin, 173,50 UT sapi Peranakan Simmental, 9 UT sapi Peranakan Brangus. Sapi-sapi betina dikawinkan secara inseminasi buatan, umur kawin pertama pada sapi PO yaitu 17,25 tahun, sapi Peranakan Limousin pada umur 18,85 bulan, sapi Peranakan Simmental 17,77 bulan, dan sapi Peranakan Brangus umur 15,5 bulan, S/C sapi Peranakan Brangus 2, sapi PO 2,07, sapi Peranakan Limousin 2,14, dan sapi Peranakan Simmental 2,16.  Interval kelahiran pada sapi PO yaitu 14,13 bulan, sapi Peranakan Simmental 13,94 bulan, sapi Peranakan Brangus 13,85 bulan,dan sapi Peranakan Limousin 13,74 bulan.  Batas umur pemeliharaan betina pada sapi PO 7,83 tahun, sapi Peranakan Limousin 6,74 tahun, sapi Peranakan Simmental 6,29 tahun, dan sapi Peranakan Brangus 6,63 tahun.  Natural increase pada sapi Peranakan Simmental 42,62%, sapi PO 17,99%, sapi Peranakan Limousin 9,84%, pada Peranakan Brangus 9,09%.  Net replacement rate pada sapi PO 333,668%, sapi Peranakan Limousin 281,818%, sapi Peranakan Simmental 261,588%, sapi  Peranakan Brangus 228,571%.  Output tertinggi pada sapi Peranakan Simmental 27,07%, sapi PO 20,86%, sapi Peranakan Limousin 14,75%, dan sapi Peranakan Brangus 9,09%.
