Fig. 3From: Effects of parity order on performance, metabolic, and hormonal parameters of grazing beef cows during pre-calving and lactation periodsNon-esterified fatty acids (NEFA; a) and β-hydroxybutyrate (βHB; b) serum concentrations in Nellore cows with different parity order under grazing according to the days relative to calving. Means with different superscripts differ from each other (P < 0.05). Days with asterisks (*) are significantly different between parities (P < 0.05)Back to article page
