ABSTRAKPenelitian ini dilakukan untuk mengidentifikasi ukuran-ukuran tubuh entok di Kabupaten (Magelang, Demak dan Pekalongan), Provinsi Jawa Tengah. Materi yang digunakan yaitu 210 ekorentok yang telah dewasa tubuh dengan rerata umur 7 bulan (70 ekor/kabupaten, 35 ekor jantan dan 35 ekor betina) pada masing-masing kabupaten. Variabel ukuran tubuh yang diamati meliputi bobot badan, panjang paruh, lebar paruh,panjang kepala, lingkar kepala, tinggi kepala, panjang leher, lingkar leher, panjang sayap, panjang badan, lingkar badan, tinggi badan, panjang dada, panjang femur, panjang tibia, lingkar tibia, panjang maxilla, dan panjang jari kaki ketiga. Data yang diperoleh dianalisis univariate dan multivariate dengan bantuan software SAS. Jarak Mahalanobis dianalisis menggunakan MEGA 5 (UPGMA) untuk membentuk pohon filogeni. Hasil penelitian menunjukkan bahwa entok jantan dan betina pada masing-masing kabupaten menunjukkan perbedaan (P<0,05) pada semua variabel yang diamati. Ukuran panjang sayap dan lingkar badan menjadi variabel pembeda pada entok antar kabupaten. Berdasarkan matrik jarak genetik, entok Magelang memiliki kedekatan dengan entok Pekalongan, tetapi berjauhan dengan entok Demak. Kata kunci: karakteristik fenotipik, ukuran tubuh, entok Body Measurement of Muscovy Duckin Three Regency of Central Java ABSTRACTThe study was conducted to identify the body measurements of Muscovy duck among three regency (Pekalongan, Magelang dan Demak)
The study was conducted to identify the body measurements of Muscovy duck among three<br />regency (Pekalongan, Magelang dan Demak) in Central Java. Material of the experiment was 210 muscovy ducks at 7 months of age (70 birds/regency, 35 males and 35 females). Parameters observed were body weight, bill length, bill width, head length, head circumference, high head, neck length, neck circumference, wing length, body length, breast circumference, body height, breast length, femur length, tibia length, tibia circumference, maxilla length, and length of third toe. Data of body measurement were analyzed through univariate and multivariate using SAS.Whereas the Mahalanobis distance were analyzed using MEGA 5 (UPGMA) to construct the phylogeny tree. Result showed that there were some differences (P<0,05) between male and female of muscovy duck in each regency at all variables. Wing length and breast circumference were the distinguishing variable between regencys. Muscovy duck from Magelang had a closer genetic distance to Pekalongan than Demak.<br />Keywords: body measurement, muscovy duck
