We studied game-farm pheasant (Phasianus colchicus Linneaus) chicks implanted with miniature transmitters to determine if surgery and implantation affected growth, behavior, or survival. Transmitters (weighing 1.2 g) were implanted subcutaneously in the interscapular region in day-old chicks. In Experiment 1, biological effects on chicks with transmitters implanted were compared with data from a control group. In Experiment 2, the effects of anesthesia only, anesthesia with an implanted transmitter, and implanted transmitter only were compared with a control. We measured responses of weight gain, survival, and pecking behavior in each experiment. In Experiment 1, we found no significant differences in weight between chicks with implanted with transmitters versus the control group during 23 days after implantation (repeated-measures ANOVA, n = 34, P = 0.34) in Experiment 1. In Experiment 2, we found overall differences in weight of treated chicks and controls (repeated-measures ANOVA, n = 76, P = 0.02). Chicks in the control group were heavier (P < 0.05) at ages 9, 11, 14, and 21 days but there was no significant differences in weight among treatments and control at 28 days (P = 0.07). Surgery and the presence of implants had no effect on survival or on pecking rates of chicks among groups in either experiment. We failed to reject the hypothesis that surgery and implantation had no effect on growth, behavior, or survival of pheasant chicks.
