Ovarian function and estrus in dairy cows during early lactation.
The onset of ovarian function and occurrence of estms were monitored in two groups of Holstein cows over the first 90 days postpartum. Group 1 consisted of 36 animals housed in a free stall area and observed continuously for estrus with closed circuit television and a time lapse videorecorder. Group 2 consisted of 33 cows housed in tie stalls with estrus detected by the herdsmen. Blood samples ...
متن کاملFollicular cysts in dairy cows
Follicular cysts are the most critical reproductive disorder in dairy cows and disturb normal ovarian cycle, resulting in the prolonged interval from calving to conception. Therefore, this condition causes significant economic losses to the dairy industry. Two direct causal factors of cyst are suggested in this review; the disorder of ovulation and the delay of regression. The disorder of ovula...
متن کاملChanges of Adipose Tissue Morphology and Composition during Late Pregnancy and Early Lactation in Dairy Cows
Dairy cows mobilize large amounts of body fat during early lactation to overcome negative energy balance which typically arises in this period. As an adaptation process, adipose tissues of cows undergo extensive remodeling during late pregnancy and early lactation. The objective of the present study was to characterize this remodeling to get a better understanding of adaptation processes in adi...
متن کاملInterferon-τ increases BoLA-I for implantation during early pregnancy in dairy cows
Interferon-τ (IFN-τ) signals pregnancy recognition in ruminants. We investigated the effects of IFN-τ produced by embryo trophoblastic cells (ETCs) on expression of bovine leukocyte antigen-I (BoLA-I), a bovine analogue of human MHC-I, in endometrial luminal epithelial cells (EECs) during early pregnancy in dairy cows. Expression of IFN-τ and BoLA-I was increased in endometrial tissues during e...
متن کاملA comparison of adrenal gland function in lactating dairy cows with or without ovarian follicular cysts.
Two experiments were conducted to determine if adrenal secretion of steroids differed between cows that formed ovarian follicular cysts and normal cycling cows. In experiment 1, lactating Jersey and Holstein cows were diagnosed as having ovarian follicular cysts (follicle diameter >or=20 mm) by rectal palpation. Following diagnosis, ovaries were examined by transrectal ultrasonography three tim...
