Antibody response in vaccinated pregnant mares to recent G3BP[12] and G14P[12] equine rotaviruses
BACKGROUND Both the G3P[12] and the G14P[12] type of equine group A rotavirus (RVA) have recently become predominant in many countries, including Japan. G3 types are classified further into G3A and G3B. The G3A viruses have been circulating in Europe, Australia, and Argentina, and the G3B viruses have been circulating in Japan. However, only an inactivated vaccine containing a single G3BP[12] s...
متن کاملThe effect of season on the ovulatory response of Merino ewes to serum from pregnant mares.
Groups of 50 ewes were injected with serum from pregnant mares on 5 occasions, 3 months apart, and ovulation rate was estimated at laparoscopy. In Exp. 1, new ewes were used at each time and 3 dose rates (identical to 400, 630 and 1000 i.u. PMSG) were studied. In Exp. 2, the same ewes were used throughout and only 1 dose was given (1000 i.u.). In both experiments the response in ovulation rate ...
متن کاملEffect of single vs multiple ovulations on oestrous behaviour and pregnancy rate in Thoroughbred mares
A relatively high rate of multiple ovulation and resulting multiple pregnancies are one of main problems in Thoroughbred reproduction. The aim of the study was to examine the relationship between the intensity of oestrous behaviour and incidence of multiple (MO) vs single (SO) ovulations in 47 Thoroughbred mares. The frequency of five distinct receptive and 12 non-receptive behavioural traits w...
متن کاملHerniation of the abdominal wall in pregnant mares.
Abdominal wall hernia was detected in 4 pregnant mares. Antemortem diagnosis of the specific abdominal wall lesion was difficult. Ventral deviation of the abdomen, associated abdominal wall edema, and pain indicated rupture of the prepubic tendon. Three mares examined at necropsy did not have a rupture of the prepubic tendon but did have herniation of the abdominal wall. Abdominal pain was seve...
متن کاملDevelopmental aspects of early pregnancy in mares
In mares, the embryo migrates to the uterus between days 5 and 6 postovulation beginning its mobility through all uterine segments, which is essential for the maternal recognition of pregnancy. During the mobility phase, the embryonic vesicle shows a linear growth rate until its fixation between days 15 and 17, when the orientation phenomenon occurs. From fixation to day 28 of pregnancy, the em...
