Our objective for this study was to determine the pattern of nutrient flux across the 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 ewes. Blood flow and net nutrient release across the PDV and liver were determined before exposure to ram...

OBJECTIVE Our purpose was to examine the hypothesis that corticosteroids, when administered extraamniotically, can enhance the labor process and reduce the induction-to-delivery interval. STUDY DESIGN A double-blind, randomized study was conducted on 98 women with a gestational age of 36 to 42 weeks, an unfavorable cervix, and medical indications for delivery, who were assigned to receive eit...

Background: Interaction between nutrition and reproduction has been established to play an important role in reproductive performance of animals. Zinc is considered be essential element required for reproduction. The present study was conducted evaluate the efficiency nano zinc (NZn) as feed supplementation on Assam Hill goats. Methods: A total twenty-four numbers 7 days post kidding doe mainta...

Parturition – control • Parturition requires myometrial contractions and cervical softening. • The myometrium is a functional syncytium (coupled by gap junctions) so contractions are coordinated. Contractions occur because action potentials cause Ca influx; oestrogen-primed myometrium shows pacemaker potentials, which initiate APs if they are large enough. Prostaglandins liberate Ca from intrac...

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...

Relationships between hormonal and metabolic changes around parturition and colostrum yield and composition were investigated in 16 Landrace x Large White primiparous sows. Blood samples were taken daily from d 105 of pregnancy to d 2 postpartum (with d 0 being the day of parturition). Colostrum samples were taken at the onset of parturition (T0), and then 3, 6, and 24 h later (T3, T6, and T24,...
