Latar Belakang. Sebagian besar peternak domba skala kecil menghadapi kendala dalam hal ketersediaan alat timbangan yang memadai untuk mengukur bobot badan ternaknya secara tepat dan akurat. Pengukuran bobot badan ternak tidak hanya dapat dilakukan dengan alat timbangan secara langsung, melainkan juga dapat diperkirakan melalui beberapa parameter ukuran tubuh ternak. Tujuan dilaksanakannya penelitian ini yaitu untuk mengetahui hubungan antara ukuran-ukuran tubuh dengan bobot badan ternak domba ekor gemuk. Materi dan Metode. Ternak domba yang digunakan pada penelitian ini yaitu 100 ekor domba ekor gemuk jantan yang berumur 1- 1,5 tahun. Alat yang digunakan yaitu timbangan digital gantung, alat tulis, pita ukur (metline) sepanjang 2 meter, dan tali tambang. Metode yang digunakan penelitian yaitu metode purposive random sampling. Variabel penelitian meliputi lingkar dada (LD/X1), panjang badan (PB/X2), tinggi pundak (TP/X3), lingkar pinggul (LP/X4), dan bobot badan ternak (BB/Y). Data yang telah diperoleh dianalisis menggunakan analisis regresi linier berganda dan korelasi. Hasil. Hasil penelitian dapat diketahui persamaan regresi Y= −38,35 + 0,50X1 + 0,32X2 + 0,13X3 + 0,04X4. Nilai koefisien determinasi (R2) sebesar 0,921, atau setara dengan 92,1% menunjukan tingkat akurasi antara variabel ukuran-ukuran tubuh dengan bobot badan domba ekor gemuk. Variabel lingkar dada memiliki korelasi sangat kuat (0,93), variabel panjang badan memiliki korelasi sangat kuat (0,90), sedangkan variabel tinggi pundak memiliki korelasi kuat (0,74), dan variabel lingkar pinggul memiliki korelasi sangat kuat (0,84). Kesimpulan. Berdasarkan hasil analisis dan pembahasan diperoleh kesimpulan bahwa bobot badan domba ekor gemuk dapat diduga dengan ukuran tubuh (lingkar dada, panjang badan, tinggi pundak, dan lingkar pinggul).

Background. Most small-scale sheep farmers face challenges regarding the availability of adequate weighing equipment to measure the body weight of their livestock accurately and precisely. Body weight measurement of livestock is not only conducted directly using scales but can also be estimated through several body measurement parameters. The purpose of this study is to determine the relationship between body measurements and the body weight of fat-tailed sheep. The objective of this study is to determine the relationship between body measurements and body weight in fat-tailed sheep. Materials and Methods. The livestock used in this study consisted of 100 male fat-tailed sheep aged between 1 to 1.5 years. The equipment utilized included a digital hanging scale, writing tools, a 2-meter measuring tape (metline), and a rope. The research employed a purposive random sampling method. The variables observed in this study comprised chest girth (CG/X1), body length (BL/X2), withers height (WH/X3), hip circumference (HC/X4), and body weight (BW/Y). The collected data were analyzed using multiple linear regression and correlation analysis.. Results. The results of the study indicated that the regression equation was Y = −38.35 + 0.50X1 + 0.32X2 + 0.13X3 + 0.04X4. The coefficient of determination (R²) was 0.921, or 92.1%, indicating a high level of accuracy between the body measurement variables and the body weight of fat-tailed sheep. The chest girth variable exhibited a very strong correlation (0.93), body length showed a very strong correlation (0.90), withers height showed a strong correlation (0.74), and hip circumference demonstrated a very strong correlation (0.84). Conclusion. Based on the analysis and discussion, it can be concluded that he body weight of fat-tailed sheep can be estimated using body measurements, specifically chest girth, body length, withers height, and hip circumference.
