Principal Component Analysis of Biometric Traits Explain the Body Weight of HF Crossbred Cattle

The present research was carried out to define the biometric traits of HF Crossbred Cattle from Livestock Research Station, AAU, Anand; Sarsa Heifer Farm - Amul Dairy, Ode Semen Station Anand. recorded on 506 and those are body length (BL), height at wither (HW), hip (HH), heart girth (HG), chest depth (CD) width (WH), live weight (BW) age. All data were grouped sex-wise. Principal component analyses revealed that six components, two principal components extracted in female male group. identified group could explain 95.88% cumulative variance. First accounted for 69.20 % variation. It represented by significant positive high loading BL (0.893), HW (0.911), HH (0.908), HG (0.879), CD (0.867) WH (0.842). second explained 26.68 total variance with age (0.915). Out one (PC1) provided a means reduction number be crossbred female. In group, 97.57% 60.58 (0.836), (0.865), (0.901), (0.768), (0.804) (0.737). 36.99 (0.888). seemed explaining maximum general conformation male. result suggests analysis (PCA) used breeding programs drastic selection elite animals.
