The purposes of the present study were to establish a noninvasive monitoring assay of fecal progestagen measurement to detect pregnancy and to identify the components of fecal progestagens in early, middle and late pregnancy in cheetahs. Feces were collected from 7 female cheetahs and analyzed from 30 days before the last copulation to parturition in 9 pregnancies. Blood was collected from one ...
The diagnosis of pregnancy in the domestic dog (Canis familiaris) often employs specialized equipment, experienced staff, and the cooperation of the bitch. These procedures can be challenging when the subject is a wild canid, particularly in a field setting. In addition, reproductive hormone assays are unreliable as a diagnostic tool because the estrous profiles of pregnant and pseudopregnant c...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
Background: Propolis (bee glue) is a resinous substance obtained from bee hives living on various plant sources. The purpose of this study was to evaluate the effects of ethanol extract of propolis (EEP) on the experimentally induced Candidial keratitis in rabbits. Methods: The alcoholic extract of propolis was prepared by 80% ethyl alcohol. After suppressing the immune system of 24 male rabb...
Dietary fiber given during pregnancy may influence sow endocrinology and increase piglet BW gain during early lactation. The aim of the current study was to determine whether dietary fiber given to sows during late pregnancy induces endocrine changes that could modulate sow colostrum production and, thus, piglet performance. From d 106 of pregnancy until parturition, 29 Landrace×Large White nul...

Negative dietary cation-anion difference (DCAD) diets fed prepartum induce a compensated metabolic acidosis, which stimulates Ca flux before calving and decreases clinical subclinical hypocalcemia after calving. Effects of low or high in these are unclear. Our objective was to determine the effects inducing acidosis amount on urinary mineral excretion serum concentrations during transition peri...
This study investigated the correlation between the body surface temperature (BST) and core body temperature of ewes and changes in BST during the prepartum stage in pregnant ewes. Four non-pregnant adult ewes were used in the first experiment. The BST of the upper neck, vaginal temperature (VT), and ambient temperature (AT) were measured every 10 min for seven days and analyzed for correlation...
The mare exhibits nocturnal uterine contractions in the last 6 days of gestation. It is hypothesized that estradiol 17beta (O17beta) may be associated with the nightly increase in uterine contractions. The 24-h secretion pattern of plasma O17beta was measured in 3 pony mares in late gestation to identify changes in release as the mare neared parturition. Blood was collected weekly at 08:00 hour...
