| Judul Artikel | HUBUNGAN LINGKAR DADA, PANJANG BADAN, JENIS KELAMIN DENGAN BOBOT BADAN DAN PERTAMBAHAN BOBOT BADAN HARIAN DOMBA BATUR |
| Abstrak | Tujuan dari penelitian adalah untuk mengetahui hubungan lingkar dada dan panjang badan dengan bobot badan dan pertambahan bobot badan harian pada Domba Batur. Menggunakan sampel Domba Batur jantan 12 ekor dan Domba Batur betina 8 ekor, umur 5 – 12 bulan, bobot rata-rata 23,97 kg. Menggunakan metode survey dan metode random sampling. Peubah yang diukur yaitu lingkar dada, panjang badan, jenis kelamin, bobot badan serta pertambahan bobot badan harian. Hasil penelitian menunjukkan: (1) persamaan regresi pada lingkar dada terhadap bobot badan Y = -50,47 + 1,02 LD (r = 0,91 dan R2 = 0,82), (2) persamaan regresi panjang badan terhadap bobot badan Y = -64,19 + 1,58 PB (r = 0,88 dan R2 = 0,78), (3) persamaan regresi berganda lingkar dada serta panjang badan terhadap bobot badan Y = -62,08 + 0,65 LD + 0,69 PB (r = 0,93 dan R2 = 0,85). Koefisien korelasi (r) yang mendekati +1,0 menunjukkan bahwa hubungan kedua variabel sangat kuat dan positif. Disimpulkan lingkar dada dan panjang badan terdapat hubungan positif yang sangat kuat dengan berat badan. Bobot badan domba Batur dapat diprediksi secara akurat melalui ukuran lingkar dada dan panjang badan. Namun pertambahan berat badan harian domba Batur tidak dapat diperkirakan dengan menggunakan lingkar dada serta panjang badan disebankan oleh koefisien determinasi yang rendah. |
| Abstrak (Inggris) | The aim of this research were determine the relationship between chest circumference and body length and body weight and daily body growth of Batur lamb. The samples used were 12 male Batur lamb and 8 female Batur lamb, aged 5 – 12 months with an average weight of 23.97 kg. The survey study was conducted using anrandom sampling method. The variables measured were chest circumference, body length, sexs, body weight and daily body weight gain. The results of the study shows that: (1) the regression equation for chest circumference on body weight is Y = -50.47 + 1.02 LD (r = 0.91 and R2 = 0.82), (2) regression equation for body length on body weight is Y = -64.19 + 1.58 PB (r = 0.88 and R2 = 0.78), (3) multiple regressionnequation of chest circumference and body length on body weight is Y = -62.08 + 0.65 LD + 0.69 PB (r = 0.93 and R2 = 0.85). The correlation coefficient (r) is close to +1.0 indicating that the relationship between the variables is positive and very strong. It was concluded that the chest circumference and body length have a very strong positive relationship with body weight. The body weight of Batur lamb can be accurately predicted using the size of the chest circumference and body length. However, daily body weight gain of Batur lamb cannot be estimated using chest circumference and body length due to its low coefficient of determination. |
