AB  - We studied the relationship between body morphometric traits, and their 
      underlying association with milk production (MP), lactation length (LL), first 
      calving interval (FCI) and subsequent calving interval (CI) of crossbred progeny 
      of Murrah x Jafarabadi buffalo aiming to assist in selection programs. We carried 
      out principal component analysis (PCA) of the body morphometric traits, which 
      include breast width (BW), thigh width (THW), hip width (HW), rump width (RW), 
      rump length (RL), body depth (BD), body length (BL), height withers (HEW), rear 
      height (RH), shoulder width (SW), thorax width (TW), loin width (LW), distance 
      from the head to ischium (DHI), and thoracic perimeter (TP). We determined the 
      association of morphometric traits with milk/reproduction traits using canonical 
      correlation analysis (CCA). The analysis revealed that the first six PCA 
      accounted for 82.14% of the total observed variation, and the traits THW, HW, TW, 
      LW, RW, HEW, TP, RH, and BW, accounted for almost half (48.00%) of the total 
      variance indicating a higher contribution in body structural conformation. The 
      first canonical function was significant (p<0.05), accounted for 72.46% of the 
      total variance, and the canonical correlation was 0.56, indicating the dependence 
      between both groups of traits. Higher canonical loadings were obtained for LL 
      (0.49), FCI (0.46), BW (-0.71), BL (-0.56), DHI (-0.34), HEW, (-0.38) and TP 
      (-0.50). These traits were most important for the derivation of canonical 
      statistical variables, and presented a higher canonical correlations (r) between 
      the dependent (LL/FCI) and independent (BW, BL, DHI, HEW and TP) groups. The 
      results could suggest that the body morphometric traits THW, HW, TW, LW, RW, HEW, 
      BD, TP, RH, and BW could play important role in body structural composition, 
      indicating a suitable functional type, and aid designing of selection programs 
      for buffalo breeding.
