Trophoblast cells from bovine somatic cell nuclear transfer (SCNT) conceptuses express major histocompatibility complex class I (MHC-I) proteins early in gestation, and this may be one cause of the significant first-trimester embryonic mortality observed in these pregnancies. MHC-I homozygous-compatible (n = 9), homozygous-incompatible (n = 8), and heterozygous-incompatible (n = 5) SCNT pregnancies were established. The control group consisted of eight pregnancies produced by artificial insemination. Uterine and placental samples were collected on Day 35 ± 1 of pregnancy, and expression of MHC-I, leukocyte markers, and cytokines were examined by immunohistochemistry. Trophoblast cells from all SCNT pregnancies expressed MHC-I, while …

Historically, the most significant losses from halogeton poisoning have been reported in sheep, with multiple catastrophic deaths documented. While recorded death losses in cattle from halogeton poisoning are less common than in sheep, recent cases, including 2 reported here, and anecdotal reports from other ranchers suggest that the impact of halogeton losses in cattle herds in the western United States is much more widespread than originally thought. Halogeton may accumulate up to 30% oxalates; a small amount of the plant (300 g) is enough to cause death in sheep. Oxalates precipitate calcium from the blood, resulting in hypocalcemia, formation of …
