“…This suggests that body weight and body length of Doro Ncanga female buffaloes increases significantly with age and animals ranging from age groups of 0-6 to 13-24 months have more potential to grow physically. However, the observation of present findings is in contrast with that of Bhagat et al (2016) who noted highest correlation coefficient between body weight and height at wither in female Sahiwal calves between 0-6 and 24-36 months of age.…”

“…The highest relationship observed between body weight and heart girth in the present study was in agreement with previous studies in buffalo (Tariq et al 2013), in sheep (Younas et al, 2013, and in cattle (Yan et al, 2009;Lesosky et al 2012;Bhagat et al 2016).…”

“…This study is in accordance with the report of Bhagat et al (2016) who observed highest correlation coefficient between body weight and body length in female Sahiwal calves of 0-6 and 24-36 months of age. This suggests that body weight and body length of Doro Ncanga female buffaloes increases significantly with age and animals ranging from age groups of 0-6 to 13-24 months have more potential to grow physically.…”

“…The correlations reported in the present study are also similar to other studies in male cattle that found a high correlation between body weight (BW) and heart girth (HG) of 0.976 and 0.875 at 0-6 and 6-12 age groups, respectively (Bhagat et al, 2016). Findings of the study were also supported by Paul and Das (2012) who found a high correlation (r=0.908) between BW and HG in Nili-Ravi buffalo male calves aged 6-12 months.…”

“…Table 3 shows the degree of correlation coefficients between body weight and linear body dimensions in different age groups of Doro Ncanga male buffaloes indicate the low and no significant correlation with BL. This is in contrast with that of Bhagat et al (2016) who found the strong correlation between body weight (BW) and body length (BL) in male Sahiwal cattle at 0-6 and 6-12 age groups. The current study also does not support previous research of Paul and Das (2012) who noted high correlation between BW and BL (r=0.722) and BW x HW (r=0.760) in Nili-Ravi male buffalo calves 6-12 months of age (see Table 3).…”

The objectives of the present study were to examine the correlation and regression of body measurements of the Doro Ncanga buffaloes in the savanna of Mount Tambora Dompu Regency, Indonesia. A total of 339 animals were used in this study. In female, body weight (BW) was found to be significantly (p<0.05) correlated with body length (BL), the degree of correlation increased from 0-6 (r=0.319) to 13-24 months (r=0.394), thereafter decreased at >36 months (r=0.160). The BW was not significantly correlated with height at wither (HW) for all 5 age groups. However, BW and heart girth (HG) were highly correlated (p<0.01) between age groups 0-6 (r=0.967) and >36 months (r=0.978). The BL was significantly (p<0.01) correlated with HW from 0-6 to 13-24 months of age, except for 25-36 months of age. The correlation between BL and HG was highly significant (p<0.01) at 0-6 (r=0.427) and 13-24 (0.371) months of age, then decreased with the increase of age. The HW had no strong correlation with HG at all groups. The regression model of BW changes with HG was predictable with R 2 values ranged from 0.896 to 0.957. In male, BW had a strong correlations with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). The BL and HW were not highly correlated with BW in all groups. However, BW was significantly (p<0.01) correlated with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). Their R 2 values were 0.958 and 0.945, respectively. A highly significant (p<0.01) correlations were also observed between BL and HW for age groups 0-6 months (r=0.677) and 7-12 months (0.462). The R 2 values were 0.458 and 0.214 for the two different age groups, respectively. The estimates of the coefficient of determinations and predictive equations show that HG alone could be used to predict BW of female and male Doro Ncanga buffalo at different age groups.
