“…Esta hiperproteinemia por hiperglobulinemia, com os valores das globulinas variando entre 5,51 ± 2,31 g/dL e 7,6 ± 0,67 g/dL nas avaliações anteriores ao parto, não foi encontrada na literatura consultada, especificamente, para a raça Jersey (KATOH, 2002;GREGORY et al, 2004;SOUZA et al, 2004;HUZZEY et al, 2009; SAUT et al, 2014) e nem para outras raças nessa fase, como a Holandesa (SOUZA et al, 2010;SAUT et al, 2014).…”

“…A redução dos níveis proteicos e de globulinas observadas já no pré-parto, não levou ao quadro transitório de hipoglobulinemia, fato descrito frequentemente nas pesquisas com animais no periparto (GONÇALVES & KOZICKI, 1997;FEITOSA & BIRGEL, 2000;FEITOSA et al, 2000;SAUT et al, 2014) Apesar de os animais aqui referidos apresentarem níveis baixos de cálcio no pós-parto, a não ocorrência de enfermidades puerperais pode ser devido ao fato de os níveis de NEFA não terem sido suficientes para promover tais desordens.…”

Purulent vaginal discharge (PVD) is a prevalent uterine disease of dairy cows during the puerperium that affects the milk production and affects the profitability of farms. The objectives of this study were to evaluate the biochemical profile, the body condition score, the milk production of cows with PVD and the effects PVD on reproductive performance. A total of 338 Holstein dairy cows aged from 3 to 5 years, from three commercial dairy farms, from Brazil, were used. Blood samples were collected within 25 ± 3 days post‐partum from Holstein dairy cows without PVD (control cows, n = 242) and cows with PVD (n = 96), based on scoring of the vaginal discharge. The body condition score and milk production were recorded on the day of sampling. The biochemical profile encompassed albumin, urea, gamma‐glutamyl transferase, calcium, fibrinogen and cholesterol concentrations. The number of services per pregnancy was lower (p < 0.01), and the number of days until first insemination and the median time to pregnancy were higher in cows with PVD (p < 0.01) when compared with control cows. Milk production and body condition score were lower (p < 0.01) in cows with PVD than in control group. Cows with PVD had lower (p < 0.05) serum albumin, urea, calcium and cholesterol concentrations, and higher serum gamma‐glutamyl transferase activity and fibrinogen concentration than cows without PVD. Our results show that cows with PVD have changes in the biochemical profile and negative effects on production and reproduction performance.

During the puerperium phase, physiological modifications occur in the reproductive tract of dairy cows, such as involution of the reduction in uterine size, removal of cellular debris and the resumption of ovarian cyclicity (Cui, Wang, Ding, Li, & Li, 2019; Sheldon, 2004). Around 90% of the cows will have bacterial contamination within the first 14 days after parturition (Sheldon, Cronin, Goetze, Donofrio, & Schuberth, 2009); however, in some cows, these bacteria remain in the uterus and contribute to a higher prevalence of puerperal diseases (Kimura, Goff, Kehrli, & Reinhardt, 2002). One of the main puerperal diseases in cattle is metritis, which is classified as puerperal metritis and characterized by an abnormally enlarged uterus with a fetid watery red-brown uterine discharge, which is associated with signs of systemic illness and fever (≥39.5°C) within 21 days postpartum; and clinical metritis is characterized by an abnormally enlarged uterus, a purulent uterine discharge detectable in the vagina within 21 days postpartum, and no signs of systemic illness (Sheldon, Lewis, LeBlanc, & Gilbert, 2006). In a previous study of 336 cows in Brazil, Paiano, Lahr, et al. (2019) found an incidence of 26.5% with metritis, which could negatively affect the welfare and productivity of the cows (Sheldon et al., 2009). After calving, dairy cows can present nutritional, hormonal and metabolic alterations that contribute to the negative energy balance (NEB) and compromise the immune function (Goff,
