INTISARI
Penelitian ini bertujuan untuk mengetahui pengaruh skor kondisi tubuh (SKT) ternak sapi terhadap keberhasilan inseminasi buatan (IB) induk sapi potong. Pendugaan SKT dilakukan secara langsung dengan observasi ternak. Penilaian menggunakan skala SKT 1-5. Keberhasilan IB dinilai berdasarkan calving interval (CI), calving rate (CR), dan service per conception (S/C). Penelitian dilaksanakan pada bulan Desember 2016 hingga Januari 2017 di Kecamatan Sanden Kabupaten Bantul. Materi yang digunakan dalam penelitian adalah 1) 51 induk sapi potong dengan syarat pernah beranak minimal 2 kali, sedang dalam periode kosong, dan diketahui sejarah reproduksinya, 2) data dari 3 Inseminator, dan 3) 45 peternak pemilik sapi. Metode penelitian yang digunakan adalah studi kasus dengan cara survey langsung ke peternakan dan dinas yang terkait, penyebaran kuisioner untuk peternak, dan wawancara dengan Inseminator. Data yang diperoleh selanjutnya dianalisis secara statistik dengan uji regresi dan korelasi. Sampel penelitian terdiri dari 3 bangsa sapi yaitu Peranakan Ongole sebanyak 37.3%, sapi Peranakan Simmental sebanyak 33.3%, dan sapi Peranakan Limousin sebanyak 29.4%. Dari penelitian diketahui rata-rata SKT sebesar 2.96; CI 14.92 bulan; CR 36.92%; S/C 2.87. Hasil uji statistik SKT tidak berpengaruh terhadap CI dan CR. SKT berpengaruh terhadap S/C dengan persamaan regresi S/C = 1.644 + 0.415 SKT. (r2)=7.9%. (R)=0,281. Kesimpulannya SKT tidak mempengaruhi keberhasilan IB dilihat dari CI dan CR. SKT mempengaruhi keberhasilan IB dilihat dari S/C. Kontribusi SKT terhadap S/C sebesar 7.9% dengan korelasi yang lemah.

THE EFFECT OF BODY CONDITION SCORE ON THE SUCCESS RATE OF ARTIFICIAL INSEMINATION IN BEEF CATTLE
IN SANDEN SUB DISTRICT

ABSTRACT
The aim of this research was to determine the effect of body condition score (BCS) on the success rate of artificial insemination in beef cattle. The estimation of BCS was carried out directly by observing the cattle. It was assesed by using BCS scale 1-5. The success rate of artificial insemination was assessed by calving interval (CI), calving rate (CR), and service per conception (S/C). The reaserch was conducted from December 2016 to January 2017 in Sanden District, Bantul Regency. The research used some materials, namely 1) 51 beef cattle that have been calving at least 2 times, it was in the days open condition, and the reproduction history was recognized, 2) data from 3 Inseminators, and 3) 45 cattle farmers. The method used in this research were case study by directly surveying in the farm and related offices, distributing questionnaires for farmers, and interviewing with Inseminators. The data obtained was analized statistically by regression and correlation test. The research sample consisted of 3 cows namely Ongole cross cow 37.3%, Simmental cross cow 33.3%, and Limousin cross cow 29.4%. It was known from the research that the average of BCS was 2.96; CI was 14.92 months; CR was 36.92%; S/C was 2.87. The result of the statistic shown that BCS has no effect on CI and CR but BCS effect on S/C with regression equation S/C = 1,644 + 0,415BCS. (r2)=7.9%. (R)=0.281. In conclusion, BCS did not affect the success of artificial insemination on CI and CR. BCS affects on the success of artificial insemination from S/C. The contribution of BCS to S/C was 7.9% with a weak correlation.
