Dalam penelitian ini digunakan 74 ekor kambing Peranakan Ettawa (PE) jantan dan di antaranya terdapat tiga ekor pejantan PE juara kontes. Tujuan dari penelitian ini untuk mengetahui hubungan antara lingkar skrotum dengan ukuran tubuh. Data yang diambil meliputi lingkar skrotum, ukuran tubuh (panjang badan, lingkar dada dan tinggi gumba). Data yang diperoleh dianalisis menggunakan análisis korelasi regresi. Hasil penelitian menunjukkan bahwa rata-rata lingkar skrotum, adalah 25,47±2,81 cm, panjang badan, lingkar dada dan tinggi gumba berturutturut adalah 71,69±9,41 cm, 86,01±10,48 cm dan 77,57±10,46 cm. Koefisien korelasi antara lingkar skrotum dengan panjang badan, lingkar dada dan tinggi gumba berturut-turut adalah 0,613, 0,692 dan 0,626. Korelasi lingkar skrotum nyata (P?0,05) terhadap panjang badan, lingkar dada dan tinggi gumba. Persamaan regresi antara lingkar skrotum (Y) dengan panjang badan (X1) adalah: Y= 12,35+0,18X1 ; lingkar skrotum (Y) dengan lingkar dada (X2) adalah: Y= 9,50+0,19X2 ; lingkar skrotum (Y) dengan tinggi gumba (X3) adalah: Y= 12,44+0,17X3. Hasil penelitian menunjukkan bahwa pada panjang badan, lingkar dada, tinggi gumba dan lingkar skrotum kambing PE juara lebih tinggi dibanding kambing sampel yaitu masing-masing sebesar 28,75%, 22,97%, 21,45% dan 12,69%. Kesimpulan dari penelitian ini adalah terdapat hubungan yang nyata antara lingkar skrotum dengan ukuran tubuh pada kambing PE.

h there were three goats contest winner. The aim of the research was to investigate the relationship between scrotal circumference with body measurements. The data included scrotal circumference and body measurements (body length, chest circumference and girth height) were recorded. The data were analysed using regression correlation analyses. The result of the study indicated that means of scrotal circumference were 25.47±2.81 cm, body lenght, chest circumference and girth height were 71.69±9.41 cm, 86.01±10.48 cm and 77.57±10.46 cm. The value of correlation coefficient ( r ) between scrotal circumference with body lenght, chest circumference and girth height were 0.613, 0.692 and 0.626. The result of the study indicated that correlation between scrotal circumference was significant (P?0.05) with body lenght, chest circumference and girth height. The linear regression between scrotal circumference (Y) and body lenght (X1) was: Y= 12.35+0.18X1 ; scrotal circumference (Y) and chest circumference (X2) was: Y= 9.50+0.19X2 ; scrotal circumference (Y) and girth height (X3) was: Y= 12.44+0.17X3. The result of the study indicated that of body length, chest circumference, girth height and scrotal circumference of male Ettawa Grade goats the contest winner than were 28.75%, 22.97%, 21.45% and 12.69% more than those of goat samples. The conclusion of this study was high relationship between scrotal circumference and body measurement there was a Ettawa Grade goats.
