The fold changes of these time points varied from 2 to 10 fold compare to -30 d before parturition
but no significant differences were found among time point -30, -15, 1, 15, 60, 120, 180, and 240 d.
Gestation lengths were comparable for all groups; all dams delivered on GD21 or GD22, and no abnormalities in parturition
The purpose of our study was to investigate colonial behavior (arrival at summering grounds, colony size and fluctuations, summer colony breakdown, migration to hibernacula following the summer roosting season) and describe reproduction events (dates of pregnancy and parturition
for adult females, and first flight and weaning of young) for eastern pipistrelles roosting in trees.
5 km a day prior to parturition
to find a place to build a nest (Jensen, 1986).
Proper vaccination of the mother before parturition
gives the newborn a head start on life.
Lopate, a veterinarian, assembles 18 chapters in this small animal neonatology reference for veterinary practitioners, students, technicians, and professional breeders that covers the reproductive physiology of pregnancy and parturition
, normal neonatology, and neonatal disorders in dogs, cats, and small exotic mammals.
We determined date of parturition
to be the mid-point between the first day we observed the female repeatedly returning to or remaining in one location and date of the previous location obtained for the female.
Clinical Q fever in roe deer might occur more frequently in late gestation and around parturition
, as in domestic ruminants (7, 8).
In early 70 and 80 decades, this syndrome was reported around parturition
widely and it was recorded in many countries [3,6].
If dispersal through agricultural fields is a more risky travel option, impending parturition
might force some females to select this travel route.
Moose (Alces alces) calving site studies have typically been conducted by searching for parturition
sites 3-4 days after birth (Leptich and Gilbert 1986, Langley and Pletscher 1994, Bowyer et al.
PCB and mercury concentrations were determined in blood samples obtained at parturition
and at follow-up.
2003) also attributed differences in settling date to time of parturition
because early settlers of Sebastes inermis to seagrass beds in Japan were born earlier than late-settling fish.
Embryos were observed in January, June and July suggesting parturition
occurs in late summer.
If sand tiger sharks had a biennial cycle, it would be necessary for all the "resting" females to leave the southeastern United States waters after parturition
and spend their off year elsewhere, just to reappear the following year at mating time.
