|
Non-obstructive egg retention is quite common in captive bred turtles and may result from several different factors, including poor husbandry and poor physical condition. Oxytocin, 1 to 40 IU/kg, can be used to stimulate oviductal contraction and induce egg deposition. The purpose of this study was to investigate the efficacy of low dose intravenous (IV) and intramuscular (IM) oxytocin for managing turtles with non-obstructive egg retention. Physical examination and radiographic and computed tomographic evaluations were performed in 39 female red-eared sliders (Trachemys scripta elegans) that were showing overt clinical signs of egg retention. After being placed for 7 days in a suitable environment without laying their eggs, a diagnosis of non-obstructive egg retention was made in 30 of the turtles. These 30 turtles were then randomly divided in two groups. Group OXY-IM (n=15) received 2 IU/Kg oxytocin IM, while group OXY-IV (n=15) received the same dose IV. If animals did not lay all of their eggs within 60 minutes, a second dose (2 IU/Kg) was administered. Follow up doses were given every 120 minutes until all eggs were laid. The mean time for animals in OXY-IM to start laying and complete egg deposition was 97 ± 22.4 minutes and 246.1± 27.37 minutes, respectively. All animals required a second dose, 10 turtles (66.6%) required a third dose, and 5 turtles (33.3%) required a fourth dose. The animals in OXY-IV started laying eggs on average 61.26±13.9 minutes post- treatment and completed laying eggs 147.2± 25.5 minutes post-treatment. Six animals (40%) required a second dose of oxytocin and 4 (26.6%) required a third dose. There were significant differences (p<0.0001) in the elapsed time between the first injection and the start of egg deposition and total egg deposition between the two treatment groups. In conclusion, oxytocin administered IV provided faster results than IM dosing for the treatment of non-obstructive egg retention in red-eared sliders. No side effects were observed in either treatment group.
