The effects of two GnRH antagonists were tested in order to delay and/or synchronise ovulation in mares. Five mares received Antarelix (0.01 mg.kg(-1)), 5 mares received Cetrorelix (the same dose), 5 mares (control mares) received the vehicle intravenously, twice daily, for 8 days from the day the largest follicle reached 22 mm following prostaglandin administration. Ovulation was postponed in ...

Hedberg Alm, Y. 2006. Oestrus in the mare with emphasis on deviant behaviour and adrenal gland function. Some owners appear to experience problems with their mares due to excessive oestrous signs and/or changes in their mare's behavioural characteristics across the oestrous cycle. Few such mares are examined at equine clinics and, thus, the cause of such behaviour is often unknown. Adrenal sex ...

An inactivated Equine herpes virus-1 vaccine was successfully improved using carbomer as adjuvant inducing high and long immunity in vaccinated mares comparison with the convention one adjuvanted Al-hydra gel saponin. Such purpose established by 0.5% to EHV-1. The applied quality control tests carried out on such revealed that it is free from foreign contaminants, safe pregnant mice potent indu...

Breeding records of 57 Arabian and 66 Thoroughbred mares were analysed to assess their reproductive performance under the subtropical conditions of Pakistan. The Arabian mares showed significantly higher conception rates (p<0.05) in second mated oestrus and foal heat mated oestrus compared to Thoroughbred mares. However, conception rates for first lifetime mated oestrus were similar in both bre...

The objective was to determine differences in follicle and reproductive hormone characteristics in mares with ovulatory and flunixin meglumine (FM)-induced anovulatory cycles. Estrous mares were given 1500 IU hCG when the follicle was ≥ 32 mm (0 h). In Experiment 1, control mares (n = 7) were not treated further. The remaining mares (n = 11) were given 1.7 mg/kg FM i.v. twice daily, from 0 to 3...
