an experiment was carried out to study the influence of the body condition score at birth on blood metabolites of goats in early lactation. sixty-eight goats were placed in three groups according to the body condition score (bcs) at parturition: from 1.00 to 2.75 (thin animals); 2.75 and 3.50 (intermediate body condition) and from 3.50 to 5.00 (fat animals). the experimental was carried out in the first sixty days of lactation and blood sampling started after parturition at weekly intervals up to the eighth week of lactation. analyses were made of the non-esterified fat acids (nefa), beta-hydroxibutirate (bhba), glucose, total cholesterol and high density lipoprotein (hdl). the plasma concentrations of the metabolites did not differ among the groups. the nefa concentrations in the animals in the three groups at birth and in the first eight weeks of lactation were 658.46 and 232.90 mg/dl, respectively and the values of bhba at birth were 10.31 ± 3.0 mg/dl for the thin animals, 6.88 ± 0.9 mg/dl for the intermediate animals and 4.21 ± 0.8 mg/dl for the fat animals. the glucose values at birth were 112.54 ± 15.4 mg/dl for the thin animals, 90.93 ± 13.5 mg/dl for the intermediate animals and 132.47 ± 26.7 mg/dl for the fat animals. the average of total cholesterol and hdl in the first eight weeks after birth were 109.01 ± 2.5; and 54.9 ± 1.39 mg/dl for the thin animals, 83.0 ± 21.7 and 56.0 ± 1.30 mg/dl for the intermediate animals and 84.3 ± 23.9 and 54.5 ± 1.93 mg/dl for the fat animals. the changes in the energy metabolism of dairy goats with medium production decreased, regardless of the body condition at birth, when supplied with high quality feed with high energy levels.
