Uterine Involution and Reproductive Performance in Dairy Cows with Metabolic Diseases.

The aim of this study was to investigate the effects of metabolic diseases on uterine involution and reproductive performance during the postpartum period. Multiparous Holstein dairy cows (n = 50) were divided into four groups based on whether they were healthy (n = 14), or had lipomobilization (n = 14), hypocalcemia (n = 11), and hyperketonemia (n = 11). Transrectal palpation and transrectal B-Mode sonography were carried out on days 7, 14, 21, 30, 45 and 60 after parturition. Cows with metabolic disease had a greater (p < 0.05) uterine size as assessed transrectally compared with cows without metabolic disease. Sonographic measurements revealed a greater (p < 0.05) horn diameter and endometrial thickness in cows of the metabolic disease groups than in the healthy cows. Metabolic disease affected (p < 0.05) the milk yield, percentage of service per pregnancy, days to first ovulation and days open. In conclusion, metabolic disease affected the uterine involution and fertility during the postpartum period.

Viral DNA sequences in peripheral blood and vertical transmission of the virus: a discussion about BPV-1

This study has detected BPV-1 DNA sequences in wart, blood and plasma samples collected from animals affected by papillomatosis, suggesting viral presence inside the cell. We sellected an animal in which we could detect BPV-1 DNA sequences in wart, blood, placenta and amniotic liquid samples and her offspring which presented BPV-1 DNA sequences in blood sample collected immediately after birth. These results show a possible vertical transmission of BPV-1.

Neste estudo detectou-se DNA de BPV-1 em: verruga, sangue e plasma de animais afetados por papilomatose. Estes resultados trazem evidências sobre possível localização intracelular do BPV-1 no sangue. Avaliamos um animal afetado por papilomatose e positivo para BPV-1 em amostras de verruga, sangue, placenta e líquido amniótico e que teve sua cria recém-nascida também positiva para BPV-1 no sangue. Estes resultados indicam possível transmissão vertical do BPV-1.
