Blood collections were taken every 20 min over 12 h on 6 occasions within 1 month before and after gonadectomy of 5 cyclic and 5 post-partum dairy cows and again on one occasion 3--5 months thereafter. By 4 days after ovariectomy of the cyclic cows (i.e. 4 days after oestrus) average plasma LH values and the frequency and amplitude of pulsatile LH release had increased about 3-fold. In the cows...
objective: the possible toxicity of drugs in pregnancy should be tested before their use in pregnant patients. in the present study, we aimed to evaluate the safety of phytovagex, a pessary formulation of nigella sativa (n. sativa), which is already in clinical use for vaginal fungal infection. materials and methods: the pregnant rats were treated intravaginal with physiological saline (vehicle...

The objective of this study was to determine the pattern of nutrient flux across portal-drained viscera (PDV) and liver in ewes with varying numbers of fetuses. Catheters were placed in the hepatic portal vein, a branch of the hepatic vein, a mesenteric vein, and the abdominal aorta of each ewe. Plasma flow and net cholesterol, nonesterified fatty acids (NEFA), and glycerol release across the P...

Ultrasonographic fetal eye measures have been used to estimate gestational age of the fetus in light horse mares. However, fetal eye measures have not been published for smaller pony breeds. This study was conducted to develop reference ranges for ultrasonographic measures of fetal eyes in small ponies for the purpose of predicting days before parturition (DBP) when breeding or ovulation dates ...
24 Holstein cows and 16 Holstein heifers in close-up period were used to evaluate the effects of ground wheat grain in prepartum diets on health and performance of dairy cows. Cows were blocked based on parity (three groups) and then randomly assigned to two experimental diets. Study rations included a treatment containing wheat with 1.62Mcal/kg NEL, 14.8%CP, 42.1%NFC, and –64meq/Kg DCAD and an...
and Implications Antibody against porcine relaxin (antipRLX540; 1:950,000) was produced in sheep and used to determine the effect on relaxin and progesterone secretion, and on parturition in late-pregnant pigs. In group 1, Yorkshire gilts with normal estrous cycles were bred on the second observed estrus and fitted with an indwelling jugular cannula and an intraperitoneal cannula on day 100 of ...
It is generally accepted that hormones and tissue growth factors are supplied from mother to neonate via mammary secretion. Among the protein hormones, insulin and prolactin are considered as the most important milk components for neonates. The significance of the thyroid hormones, namely triiodothyronine (T3) generated locally by 5'-monodeiodinase (5'-MD) in the mammary tissues, for the mammar...
