[In vitro parameters for the comprehension of the immunocompetence of chickens of different lines. 2. Testing an immunocompetent parameter as a selection criterion in the chicken].
A cytotoxicity test using blood and saccharomyces cells (SCT) was experimentally applied in a sample of pedigreed commercial chickens from different lines over 3 generations to test its usefulness as a parameter for the nonspecific defense capacity. The results clearly show a significant difference between the SC rates in the different lines. Positive heritabilities exist between the SC rates of the 3 generations. The correlations between SC rates of males in the first generation and parameters of layer productivity of their daughters are nonsignificant. The possibility to integrate the parameter SC into the selection index is critically discussed.
