Abstract: Ayam IPB-D1 merupakan ayam silangan dengan komposisi darah 25% ayam pelung, 25% ayam sentul, 25% ayam kampung dan 25% ayam pedaging unggul cobb. Ayam IPB-D2 merupakan hasil seleksi ayam IPB-D1 terhadap sifat ketahanan penyakit. Ayam IPB-D3 merupakan ayam hasil seleksi ayam IPB-D1 terhadap sifat pertumbuhan cepat. Penelitian bertujuan mengkaji perbedaan ukuran dan bentuk tubuh ayam IPB-D1, ayam IPB-D2 dan ayam IPB-D3 dewasa (umur 20‒68 minggu) melalui Analisis Komponen Utama (AKU). Penelitian dilakukan dengan mengukur permukaan tubuh linear ayam yang meliputi panjang femur (X1), panjang tibia (X2), panjang tarsometatarsus (X3), lingkar tarsometatarsus (X4), panjang jari ketiga (X5), panjang sayap (X6), panjang maxilla (X7) dan tinggi jengger (X8). Persamaan ukuran tubuh yang diperoleh pada penelitian ini: Y1= 0,25X1 +0,43X2 +0,35X3 +0,12X4 +0,18X5 +0,69X6 +0,06X7 +0,32X8 dan persamaan bentuk tubuh: Y2= ‒0,32X1 +0,48X2 +0,02X3 ‒0,12X4 +0,07X5 ‒0,49X6 +0,01X7 +0,63X8. Penciri utama ukuran (size) dari persamaan tersebut adalah panjang sayap. Penciri bentuk (shape) dari persamaan tersebut adalah tinggi jengger. Kata kunci: ayam IPB-D1, ayam IPB-D2, ayam IPB-D3, bentuk tubuh, ukuran tubuh
IPB-D1 chicken is a crossbred chicken with a blood composition og 25% pelung chicken 25% sentul chicken 25% kampong chicken and 25% cobb superior broiler. IPB-D2 chicken is the result of the selection of IPB-D1 chicken for disease resistance traits. IPB-D3 chicken is the result of IPB-D1 chicken selection for fast growth traits. The study aimed to assess differences in body size and shape of IPB-D1 chicken, IPB-D2 chicken and IPB-D3 chicken in the adult period (aged 20-68 weeks) through Principal Component Analysis (PCA). The study was conducted by measuring the linear body surface of chickens including femur length (X1), tibia length (X2), tarsometatarsus length (X3), tarsometatarsus circumference (X4), third finger length (X5), wing length (X6), maxilla length (X7) and cockscomb height (X8). The body size equation obtained in this study: Y1 = 0.25X1 +0.43X2 +0.35X3 +0.12X4 +0.18X5 +0.69X6 +0.06X7 +0.32X8 and body shape equation: Y2= ‒0.32X1 +0.48X2 +0.02X3 ‒0.12X4 +0.07X5 ‒0.49X6 +0.01X7 +0.63X8. The main characteristic size is the length of the wings. The main characteristic shape is comb height. Keywords: body shape, body size, IPB-D1 chicken, IPB-D2 chicken, IPB-D3 chicken
