nything that compromises sow milk yield would be expected to have a negative impact on piglet performance. Periparturient hypogalactia syndrome has been associated with endometritis.1 Most sow herds have some incidence of endometritis, with reported incidences ranging from 1.1%–37.2% for different herds.2 Recent interest has focused on the postpartum administration of prostaglandin F2α (PGF2α) ...

This study evaluated the effect of a prostaglandin F2? (PGF) analogue as an ovulatory stimulus in dairy cows and buffaloes raised Amazon biome. To this end, three experiments were performed state Rondônia, located In Experiment 1, 22 lactating received 2 mg intramuscular (I.M.) estradiol benzoate (EB) on day 0 intravaginal progesterone-releasing device (CIDR) from to 9 protocol. On days 8 9, al...

An FP prostaglandin (PG) receptor on the A7r5 rat aorta smooth muscle cell line has been characterized by assays of phosphoinositide (PI) turnover and intracellular calcium mobilization stimulated by structurally diverse PGs. In the PI turnover assay, cloprostenol was the most potent PG tested, with a potency (EC50) of 0.84 +/- 0.06 nM (mean +/- S.E.M., n = 34), and was a full agonist. Other kn...

AIM The aim of this study was to evaluate the efficacy of three different treatment protocols for estrus induction and conception rate in postpartum anestrus buffaloes during breeding season under field conditions. MATERIALS AND METHODS The 47 postpartum anestrus buffaloes of the 2nd to 6th parity were divided into three groups. Group 1 (n=16): Buffaloes received cosynch treatment, that is, b...

Background and Objective: Ineffective estrus detection is the foremost limiting factor in the fertility of farmed cattle worldwide. Therefore, this study investigates the effect of three synchronization protocols with Fixed Time Artificial Insemination (FTAI) on the pregnancy rate of crossbred dairy cows. Methodology: Ninety one cows were assigned to four groups where the Body Condition Score (...

A detailed pharmacological characterization of the prostaglandin (PG) receptor coupled to phosphoinositide (PI) turnover and intracellular calcium mobilization in Swiss 3T3 mouse fibroblast cells was undertaken. The pharmacological profile of this functional receptor was compared with the pharmacological profile of specific [3H]PGF2 alpha binding to bovine corpus luteum membranes, which are kno...
