The energetic status of high‐yielding Holstein‐Friesian dairy cattle was studied during peripartum under field conditions using body condition score (BCS), glycemia, seric ß–hydroxybutyrate and adipose tissue cellularity. This last method was tested as a complementary tool for energetic status assessment. Biopsies of pericaudal subcutaneous adipose tissue were obtained from 25 multiparous animals at 28 days before and 21 days after parturition. Samples were routinely processed for histological examination and stained with haematoxylin and eosin (H&E). The mean diameter of adipocytes (MDA) was measured with the aid of a digital image processor. During the same period, blood samples were collected weekly for metabolite determinations. The MDA at 28 days pre‐partum and 21 days post‐partum were 72.1 vs. 66.2 μm respectively (p = 0.055), and the corresponding BCS at these moments was 3.32 vs. 3.19 (p = 0.068). At ?28 days pre‐partum, the BCS was positively correlated with MDA (Pearson’s r = 0.521, p = 0.016) and with glycemia (Pearson’s r = 0.404, p = 0.056). Correlations between BCS and MDA, and between BCS and glycemia, with ß–hydroxybutyrate although not significant, suggest that routine histological preparations of biopsies from subcutaneous adipose tissue could be included as an easy and valuable tool for research purposes to evaluate metabolic adaptation of dairy cows to peripartum, as well as the incidence of metabolic disorders and productive performance. 相似文献
