The effects of inbreeding on hatchability. Rapports du Congres du Petit Elevage. Anvers 4–5 Octobre 1930. Prof. A. G. Dumon, Lecturer at Louvain University, Director of the Experimental Station at the Boerenbond Belge.

Conclusions.

(a) Since the crossing of strains from different families eliminated the disastrous effects of inbreeding, it is possible, without incurring any very great hazards, to practice more or less close inbreeding to as pure a hereditary formula as possible.
