A Comparison of the Effects of Skin Implants and Skin Grafts on the Cellular Constituents of Chicken Blood

Estimation of Genetic Diversity Among Strains and Breeds of Chickens by Lymphocyte Increases Following Skin Grafting ,

“…2 cytes, measured on the fifth postoperative day, and the relationship coefficient between host and donor. Berry et al (1958) obtained an average correlation coefficient of -0.49 (P < .05) in a similar set of experiments, using postoperative lymphocyte increases on the third day. Craig and Hirsch (1957), using two breeds, also found that grafts from one breed to the other gave a significantly greater response than grafts exchanged within the breed.…”

“…These results are further illustrated in Table 5 where the three-day postoperative lymphocyte percentages are grouped according to whether the donors and hosts were of the same strain, of different strains of the same breed, or of different breeds. In the work of Craig and Hirsch (1957) and of Berry et al (1958) significant regressions were established for increases in the relative lymphocyte percentage following skin grafting, with known genetic relationship coefficients of donors and hosts. In the work of Craig and Hirsch (1957) and of Berry et al (1958) significant regressions were established for increases in the relative lymphocyte percentage following skin grafting, with known genetic relationship coefficients of donors and hosts.…”

“…Craig and Hirsch (1957), using two breeds, also found that grafts from one breed to the other gave a significantly greater response than grafts exchanged within the breed. This study was carried out to determine whether a technique utilizing three-day postoperative lymphocyte percentages following skin grafting would adequately measure genetic The surgical techniques used in this study were the same as those described by Berry et al (1958). The estimation of genetic diversity of strains and breeds used in crossing would be of value to the extent that heterosis is associated with such diversity.…”
