“…The observed variation in NEFA and BHB values over time in Gyr cows agrees with previous reports on Holstein cows [44,54,61] and crossbred Holstein × Gyr cows [15][16][17]62]. However, lower NEFA and higher BHB values after calving were reported in Jersey cows [63].…”

“…The elevated serum cholesterol levels found at 21 and 42 DIM were similar to those reported in Holstein [66,67], Holstein × Gyr [15,17,62,65], and low-yielding Gyr cows [18,19]. Higher cholesterol levels reflect a positive energy balance that is directly related to increased dry matter intake [66,67].…”

“…According to a previous report [76], P is expected to decrease at the day of calving. The same variation was found in Holstein × Gyr cows [15,17,71], and in Jersey cows [63]. In addition to the levels of Ca, the levels of P decrease on the day of parturition, owing to the loss of large amounts of this mineral in the colostrum [74].…”

“…Information on this subject in Zebu dairy cows is scarce. Some studies conducted by Brazilian researchers on crossbred Holstein × Gyr cows have shown that high-producing cows have metabolic imbalances similar to those present in Holstein cows [14][15][16][17]. Specifically, for Gyr cows, information on the metabolic aspects during the transition period is limited to two studies that included cows with low milk production (6 to 9 kg/day) and measured a smaller number of metabolites [18,19].…”

This study aimed to evaluate the effects of parity, body condition score (BCS) at calving, and milk yield on the metabolic profile of Gyr (Zebu) cows. Healthy cows in late pregnancy were grouped according to parity (primiparous, biparous, and multiparous); to BCS scale at calving (high—HBCS and normal—NBCS); and to milk yield (high—HP and moderate—MP production). BCS was assessed, and blood samples were collected on −21, −7, 0, 7, 21, and 42 days relative to parturition. The concentrations of non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), cholesterol, glucose, total protein (TP), albumin, total calcium (Ca), phosphorus (P), and magnesium (Mg); and activities of aspartate aminotransferase and gamma-glutamyltransferase were measured. Data were analyzed by two-way repeated measures ANOVA. The frequencies of high lipomobilization, subclinical ketosis, subclinical hypocalcemia (SCH), and the occurrence of diseases during early lactation were established. Regardless of grouping, NEFA, BHB, and cholesterol increased during early lactation; glucose showed higher values at calving; TP and albumin were higher at 21 and 42 DIM; and Ca, P, and Mg were lower at calving. Parity had little effect on the metabolic profile, HBCS did not differ from NBCS cows, and HP did not differ from MP cows in most metabolites. High lipomobilization in early lactation and SCH at calving were the most common imbalances but were not related to postpartum diseases. High-yielding Gyr cows have a balanced metabolic profile during the transition period, with few biologically relevant effects of parity, BCS at parturition, or milk yielded.
