**5.2 Comparison of stretch attend posture frequency (SAPLDT) in the light/dark transition box among the experimental groups**

The mean ± SEM SAP frequency for the control, CdCl2 (14 days), CdCl2 (28 days), CdCl2 + Zinc, and CdCl2 + vitamin E groups were 2.00 ± 0.71, 3.60 ± 0.51, 4.70 ± 0.41, 1.60 ± 0.51, and 1.60 ± 0.51 respectively.


### **Table 1.**

*Comparing the occurrence of Rearing, Stretch Attend Posture (SAP), Transition between Light and Dark (TLD), Dark Duration in Light and Dark (DDLD) Transition Box Test, and Light Duration in Light and Dark (LDLD) Transition Box Test among various groups.*

The results showed that there was no discernible change in the SAP frequency between the CdCl2 group and the control group. Yet when compared to the CdCl2 group, the SAP frequency in the CdCl2 + Zinc and CdCl2 + vitamin E groups was considerably lower (p < 0.05) (see **Table 1**).
