Genomic DNA extracted from bovine mummified tissue is valuable material for detection of some genes that may contribute to fetal abnormalities. In this study bovine genomic DNA was extracted from the hardened tissue samples of ten bovine mummified fetuses. The amount of genomic DNA extracted from 2 g of the mummified tissues by the phenol/chloroform-ethanol method was low (less than 4 microg/ml...
Although acceptable rates of blastocyst formation are achieved with in vitro production of bovine embryos, several problems still compromise the subsequent development of the fetus and newborn, especially in embryos originating from somatic cell nuclear transfer. Routinely, the potential development of a bovine conceptus is predicted either on blastocyst quality or on various parameters related...
Bovine viral diarrhea virus (BVDV) isolation and antibody survey were performed using 2,758 fetal bovine sera (FBS) collected from slaughterhouses in New Zealand, Australia and the Dominican Republic, and then sent to Japan to manufacture commercial serum for cell culture use. FBS in the Dominican Republic were pooled for each several individuals, and those collected in other countries were sep...
and peninsulae corresponding to preserved cortex. There was variable preservation of the cerebrum, total liquefaction of occipital lobes, and irregular preservation of the outer layers of some parts of the temporal and frontal lobes. Altogether, the picture was compatible with severe porencephaly or hydranencephaly. The spine showed no sign of scoliosis, and movement of the limb joints was not ...
Several sheep fetuses were thymectomized, and their tails were removed at 58 to 65 days of gestation for tissue culture. Bovine leukemia virus (BLV) antigens were detected in serial culture of tissues from fetuses whose dams and sires were both BLV positive. However, no BLV antigens were detected in serial cultures of tissues from fetuses whose dams were negative but whose sire was positive. Pr...
This study demonstrated that the modified-live bovine viral diarrhea virus (BVDV) type 1 and 2 fractions of a multivalent vaccine protected pregnant heifers and their fetuses against virulent BVDV types 1 and 2 challenge exposures at 370 days after vaccination. All BVDV vaccinated heifers inoculated with either BVDV type 1 or 2 at approximately 62 to 94 days of gestation delivered fetuses or ca...
BACKGROUND In order to establish a reliable non-invasive method for sex determination in a bovine fetus in a routine setting, the possibility of identifying specific sequence in the fetal X and Y-chromosomes has been evaluated in maternal plasma using conventional multiplex polymerase chain reaction (PCR) analysis. The aim of this study was to provide a rapid and reliable method for sexing bovi...
