The physiological responses in terms of respiration rate (RR) and rectal temperature (RT) of 30 West African Dwarf (WAD) does were monitored after a single im injection of different doses of progestagens meant for synchronising oestrus. The treatments involved im injection of 1) 2 ml of sterile water (Control); 2) 25 mg Medroxy Progesterone Acetate, MPA; 3) 50 mg MPA; 4) 50 mg Progesterone and 5) 100 mg progesterone. The RR and RT of each animal were measured at 9:00, 13:00 and 17:00 h for 21 days after each injection. In all the treatment groups the RT did not change significantly (P> 0.05) during the weeks following treatment. On the contrary the RR was significantly higher (P< 0.05) in the week after injection than in the pre-injection period. Both the RR and the RT were higher at 13:00 h and 17:00 h than at 9:00 h. The RR was more influenced by the animal body size than the RT, while the ambient temperature and humidity affected both the animal's RT and RR. These results indicate that the thermorespiratory function of WAD does under their native humid environment is not negatively affected by injecting ≤ 100 mg progesterone or ≤ 50 mg MPA to synchronize oestrus. |
