The objective of the present study was to determine the phenotypic correlations among the physical indicators, blood metabolites and 6% FCM yield in high yielding Murrah Buffaloes. During the dry period, Body weight (BW) showed a significant positive correlation with Body Condition Score (BCS) (P<0.01) and Serum Glucose (SG) concentration (P<0.05), and negative correlation with serum non esterified fatty acids (SNEFA) (P<0.01) concentration. The same correlation pattern continued up to calving, except for SNEFA concentration which did not show any relation with BW and BCS. Later, 6% Fat corrected milk yield (FCMY) negatively correlated (P<0.05) with BCS at 30d postpartum, followed by a strong positive (P<0.01) correlation with BCS, BW, and SG levels at 60 d postpartum. Although non significant, SG showed a negative correlation with 6% FCMY at calving, followed by a positive (P<0.01) and negative (P<0.01) correlation at 60 and 90 d postpartum, respectively. Further, a trend of decreased 6% FCMY and increased SG concentration is observed at 90 d postpartum owing to a negatively correlated SG levels with 6% FCMY. The strong correlations observed among the serum metabolites and physical indicators evidence the potentiality of BCS, BW, SNEFA, SG levels and 6% FCMY in anticipating the total milk yield and metabolic diseases induced by negative energy balance in high yielding Murrah Buffaloes.
