“…However, the reduced milk production, high SCC, and higher occurrence of subclinical and clinical mastitis have been reported in herds with very high BVDV antibody titers. This was observed both before and immediately after the institution of significant BVDV eradication and control programs in Europe [19][20][21][22][23].…”

“…A dairy herd containing PI infected animals generally has a higher incidence of mastitis (both subclinical and clinical), and frequently has a higher somatic cell count (SCC) than comparably managed BVDV free herds [19][20][21][22]. The effects of BVDV on milk production include: an average loss of 368 kg of milk, 9.35 kg of protein and 10.2 kg of fat per cow per lactation [23].…”

The aim of this study was to evaluate secondary clinical disease, milk production efficiency and reproductive performance of heifers and cows persistently infected (PI) with bovine viral diarrhea virus type 2 (BVDV type 2). PI animals (n = 25) were identified using an antigen capture ELISA of ear notch samples. They were distributed into three age groups: ≤ 12 (n = 8), 13 to 24 (n = 6) and 25 to 34 (n = 11) months old. A control group of BVDV antigen ELISA negative female cattle that were age matched to the PI animals was utilized from the same herd. The PI group had a 1.29 higher odds ratio for diarrhea than controls (p = 0.001, IC95% = 1.032–1.623) and 1.615 greater chance of developing bovine respiratory disease (BRD) (p = 0.012, IC95% = 1.155–2.259). The age at first insemination (p = 0.012) and number of insemination attempts required to establish the first pregnancy (p = 0.016) were both higher for PI than controls. Milk production was higher for control cows than PI cows during most of the sampling periods. Somatic cell counts (SCC) were higher in PI cows than the controls at all sampling points across lactation (p ≤ 0.042). PI cattle had a higher incidence of disease, produced less milk, a higher SCC, and poorer reproductive performance than control cattle in this study.

“…For herds in which BVDV control measures were applied, small milk production losses due to BVDV infection were also reported by Marschik et al (2018), who presented that the milk production of BVDV infected herds was 0.18 kg/cow per day lower than that of uninfected herds in Styria, Austria.

Article historyBovine virál diárrheá virus (BVDV) is án importánt virál páthogen in cáttle. There áre á few reports of this diseáse in northeástern Brázil, máinly in the semiárid region. The goál of this study wás to determine both the frequency of seropositive ánimáls, ánd the risk fáctors for BVDV in the municipálities of Báhiá ánd Pernámbuco. A non-probábilistic sámpling wás initiálly employed to determine the properties to be visited, whereás á probábilistic sámpling wás used to determine the number of ánimáls per property. Serum sámples were submitted to á seroneutrálizátion test to determine the ántibody titer for BVDV. An epidemiologicál questionnáire wás used in the herds to eváluáte the correlátion ánd ássociátion between possible risk fáctors ánd BVDV infection in these herds. Of the 257 ánimáls in the study, 144 were positive for infection BVDV, resulting in án overáll frequency of 56.0%. The highest frequency wás observed in Miguel Cálmon (76.1%) ánd followed by Senhor do Bonfim (53.1%). The váriábles identified ás risk fáctors for the BVDV infection were án extensive breeding system (OR = 2.58) ánd á mixed livestock purpose (beef ánd dáiry) (OR = 3.32). The presence of BVDV-seropositive ánimáls in the ássessed municipálities suggests the circulátion of the virál ágent in these locátions. Therefore, control ánd preventive meásures must be implemented in order to minimize losses due to the diseáse, such ás monitoring of the properties through láborátory tests, eliminátion of infected ánimáls, ánd the use of váccines in the indicáted regions by the ánimál heálth depártment.
