Effect of the racial group and body condition score at calving on production performance and metabolic profile of buffaloes during the transition period

This study evaluated the body condition score (BCS) at calving and breed (B) effects on milk composition, yield, performance, physiological parameters, hemogram, blood metabolites, and urinary metabolites in the transition and early lactation periods of Mediterranean (MED) and Murrah (MUR) buffaloes. Twenty MED and fifteen MUR buffaloes were distributed into four experimental treatments, in a completely randomized design, considering their racial groups and BCS (LBCS  = low; HBCS = high): LBCS MED (N = 9); HBCS MED (N = 11); LBCS MUR (N = 8); HBCS MUR (N = 7). Animals were monitored during the last 21 days of gestation and first 56 days postpartum and kept under the same management and feeding conditions. During data collection, milk composition, yield, performance, physiological parameters, hemogram, blood metabolites, and urinary metabolite s were evaluated. Higher milk production and fat-corrected milk were observed in MED than MUR buffaloes. Breed effects were observed on body weight, rectal temperature, glucose, urea, calcium (Ca) concentrations, and BCS effects on total protein, albumin, urea, and Ca. There were BCS effects on hema tocrit, neutrophils, eosinophils, and interactions between B × BCS for lymphocytes and platelets. There were breed effects on urinary concentrations of chlorine, uric acid, and interactions between weight (W) × B on chlorine and urea. The MED buffaloes can be considered the most prepared t o undergo physiol...
