      Abstract
      Penelitian ini bertujuan menganalisis morfometrik dan menentukan penciri utama pada sapi pejantan Peranakan Ongole (PO), Brahman, Angus dan Belgian Blue (BB) di Balai Inseminasi Buatan (BIB) Lembang. Total sampel yang digunakan dalam penelitian ini berjumlah 47 ekor sapi pejantan. Peubah ukuran-ukuran tubuh yang diamati terdiri atas tinggi pundak, panjang badan, tinggi pinggul, lebar pinggul, dalam dada, lingkar dada dan lebar dada. Data pengukuran ukuran-ukuran tubuh dikoleksi di BIB Lembang pada Maret 2021. Data ditabulasi dengan mengoreksi berdasarkan umur dan data dianalisis menggunakan uji t dan analisis komponen utama (AKU). Hasil uji t terhadap ukuran tubuh antara keempat bangsa sapi pejantan sebagian besar menunjukkan perbedaan (P<0.05). Adapun peubah penciri untuk sapi Brahman dan BB tidak memperlihatkan penciri khusus untuk ukuran tubuh. Penciri ukuran tubuh terdapat pada sapi PO, yaitu lebar dada, lebar pinggul, lingkar dada, dalam dada dan panjang badan. Penciri ukuran tubuh dari sapi Angus adalah lebar dada dan lebar pinggul. Hasil penelitian ini diharapkan dapat dijadikan sebagai informasi dasar dalam strategi program pemuliaan ke depan.
       
      This study aims to analyze the morphometrics and determine the main characteristics of Ongole Crossed, Brahman, Angus and Belgian Blue (BB) at the Institute for Artificial Insemination Lembang. The number of samples used in this study found 47 bulls. The variables of body measurements observed consisted of whithers height, body length, hip height, rump width, chest depth, chest girth, and chest width. The measurement data was taken in March 2021. Data were tabulated by correcting by age and data analysis using t-test and principal component analysis (PCA). The results of the t-test on body size between the four breeds of bulls mostly shows differences (P<0.05). Meanwhile, the characterizing variables for Brahman and BB cattle did not show specific characteristics for body size. Characteristics of body size found in PO cattle are chest width, hip width, chest girth, chest depth and body length. While Angus cattle are chest width and hip width. The results of this study are expected to be used as basic information in breeding program strategies.
