Abstract


Data diperoleh melalui pencatatan dan pengamatan dari 170 ekor induk kerbau. Analisis data dilakukan menggunakan analisis regresi yang meliputi selang beranak sebagai variabel terikat dan bobot badan, SKT sebelum beranak dan SKT sesudah beranak sebagai variabel bebas. Ratarata selang beranak, bobot badan , SKT sebelum beranak, SKT sesudah beranak berturut-turut adalah adalah 19, 18 bulan; 440,52 ± 6,26; 3.24 ± 0.55; 2.77±0.04 (rata-rata ± SE). Hasil analisis statistik menunjukkan bahwa koefisien korelasi masing-masing variabel bebas yaitu bobot badan dan SKT sebelum beranak terhadap variabel terikat yaitu selang beranak berturut-turut adalah - 0,51dan -60,75. Koefisien determinasi (R2) yakni kontribusi keragaman bobot badan, SKT sebelum beranak, SKT sesudah beranak adalah 0,49. Variabel bobot badan dan skor kondisi tubuh sebelum beranak yang berpengaruh nyata pada = 5%. Analisis statistik menunjukkan bahwa bobot badan induk dan skor kondisi tubuh sebelum beranak berpengaruh nyata (P<0,01) terhadap selang beranak Berdasarkan hasil penelitian ini dapat disimpulkan bahwa bobot badan dan Skor Kondisi Tubuh (SKT) sebelum beranak mempengaruhi selang beranak. Kata kunci: selang beranak. Bobot badan, skor kondisi tubuh, kerbau
