Abstract
Penelitian ini dilaksanakan di Wareng Farm Bima Sukses Kabupaten Tuban, dari Desember 2020 sampai Januari 2021. Tujuan dari penelitian ini untuk mengetahui korelasi antara bobot badan dan statistik vital dengan lingkar skrotum Domba Ekor Gemuk di Kabupaten Tuban. Materi yang digunakan untuk penelitian ini sebanyak 70 ekor Domba Ekor Gemuk (DEG) jantan yang berumur 8-12 bulan dengan kriteria yang ternak dalam kondisi sehat dan tidak memiliki kecacatan fisik dan alat reproduksi. Metode penelitian yang digunakan adalah metode survey yang dilakukan di Kabupaten Tuban. Alat yang digunakan dalam penelitian ini yakni pita ukur yang digunakan untuk mengukur panjang badan, lingkar dada, dan lingkar skrotum, tongkat ukur yang digunakan untuk mengukur tinggi badan ternak dan timbangan digital yang digunakan untuk menimbang bobot badan ternak. Data yang diperoleh dianalisis dengan menggunakan korelasi dan regresi linier sederhana. Hasil penelitian ini menunjukkan bahwa korelasi bobot badan dengan lingkar skrotum sangat nyata (P<0,01) yang mana diperoleh Y=16,82 + 0,25X, koefisien korelasi (r) sebesar 0,415 dan koefisien determinasi (R2) 17,19%. Korelasi antara panjang badan dengan lingkar skrotum tidak nyata (P≥0,05) yang mana Y= 21,928 + 0,052X, koefisien korelasi (r) 0,083, dan koefisien determinasi (R2) 0,69%. Korelasi antara lingkar dada dengan lingkar skrotum sangat nyata (P<0,01) dengan yang mana diperoleh Y= 8,762 + 0,210X, koefisien korelasi sebesar (r) 0,313, dan koefisien determinasi (R2) 9,78%. Dan untuk korelasi antara tinggi badan dengan lingkar skrotum adalah nyata (P<0,05) yang mana diperoleh, Y= 12,54 + 0,196X, koefisien korelasi (r) 0,296, koefisien determinasi (R2) 8,75%. Dengan demikian seleksi pejantan pada Domba Ekor Gemuk yang didasarkan pada lingkar skrotum dapat diukur dengan menimbang bobot badan dan pengukuran lingkar dada.
English Abstract
The aim of the research was to determine the relationship between body weight, vital statistics and scrotal circumference. This research was conducted at Wareng Farm Bima Sukses Tuban East Java, from December 2020 to January 2021. The material used for this research was male 70 fat-tailed sheep (DEG) aged 8-12 months with criteria that livestock are in healthy and not have physical disabilities. The method used is survey method. The observed variables in this research were body weight, chest circumference, body length, body height and scrotal circumference. Data obtained were analyzed by correlation and simple linier regression analysis. The result of research showed that there are high significant relationship (P<0.01) and medium correlation between body weight and scrotal circumference. The linier regression equation between body weight and scrotal circumference with indicated Y=16.82 + 0.25X, 0.415 corelation coefficient (r) and 17.19% determination coefficient (R2). While correlation between vital statistics with scrotal circumference is weak, those are correlation between body length and scrotal circumference have not significant relationship (P≥0.05) which is the indicated Y= 21.928 + 0.052X, 0.083 corelation coefficient (r), and 0.69% determination coefficient (R2). Correlation between chest circumference and scrotal circumference have high significant relationship (P<0.01) which is the indicated Y= 8.762 + 0.210X, 0.313 corelation coefficient (r), and 9.78% determination coefficient (R2). And then correlation between body height and scrotal circumference have significant relationship (P<0.05) which is the indicated Y= 12.54 + 0.196X, 0.296 corelation coefficient (r), and 8.75% determination coefficient (R2). It was concluded that correlation between body weight and chest circumference with scrotal circumference have high significant relationship and also they can be used as a predictor for selection male Fat-Tailed Sheep.
