Pre-ovulatory follicular characteristics and ovulation rates in different breed crosses, carriers or non-carriers of the Booroola or Cambridge fecundity gene.
Terminal follicular dynamics and ovulation rates (OR) were compared in different local breeds after introducing fecundity genes of different origin. Crossbred ewes which were carriers (F+) or non-carriers (++) of Booroola (BFec) or Cambridge genes (CFec) were included: CambridgexCambridge (CC), CambridgexSuffolk (CS), CambridgexTexel (CT), BooroolaxTexel (BT) and BooroolaxGerman Mutton Merino (...
متن کاملIndividual differences in LH and FSH responses to orchidectomy and testosterone replacement therapy in rams.
Profiles of LH and FSH levels and pituitary LH responses to exogenous luteinizing hormone releasing hormone (LHRH) have been characterized in rams, castrated rams (wethers), and wethers implanted with testosterone. Rams were castrated when adult, and, at the time of castration, two groups of wethers were implanted with either four or eight testosterone capsules. Rams showed random pulses of LH ...
متن کاملThe Effects of Trifluralin on LH, FSH and Testosterone Hormone Levels and Testis Histological Changes in Adult Rats
Background Trifluralin is a herbicide and used in agriculture widely. It enters plants through developing roots and stops plant cells from division and elongation (meristemic inhibitor). Extensive application of trifluralin to control annual grasses and broadleaf weeds in agriculture, horticulture and horn garden, leads to environmental pollution and its entrance into the food chain could have ...
متن کاملP-39: Effect of L-Carnitine on Serum FSH, LH and Testosterone Levels in Adult Male Rats
Background: The benefit effect of L-carnitine is proposed for treatment of obesity as long time periods. So, in the present study, effect of L-carnitine on serum FSH, LH and testosterone levels in adult male rats is evaluated. Materials and Methods: Rats were treated different doses of L-carnitine tartarate daily for 16 days, peritoneally. The control group was treated saline as vehicle. After ...
متن کاملEffect of naloxone on the plasma levels of LH, FSH, prolactin and testosterone in Beetal bucks.
Ten adult male Beetal goats were used for the study to elucidate the modulation of gonadotrophin, prolactin and testosterone secretion by endogenous opioid peptides. An indwelling catheter was placed in the jugular vein of each buck 20h before the onset of the experiment. Bucks were divided randomly into two groups: Group I (n=5) received naloxone at a dose rate of 1mg/kg body weight (BW) and G...
