Evolution of full-thickness and pinch skin allografts evaluation at COBB 500 hybrids after immunotolerance induction in the thirteenth day of embryonic stage.

Abstract

The purpose of this experiment was the macroscopic evaluation of the evolution of the allogenic skin grafts, evolution made through two surgical techniques (full-thickness skin grafts and pinch grafts) on COBB 500 hybrids. There have been used 20 birds aged four weeks and they have been separated in two groups: a control group (n=10) and an experimental group (n=10) to which, on day thirteen of the embrionary development, has been inoculated a concentrate of mature lymphocytes from the donor bird of skin grafts (hybrid Ross), with the aim of offering immunotolerance. The subjects have been monitored daily during the first five days after transplant and then, every two or three days for the full-thickness skin grafts and every two days for the pinch grafts, looking at the macroscopic characteristics of the transplanted tissue, among the most important being: color, aspect and adherence to the bed of the skin graft, as well as the aspect of the sides of the wound.
