Annual Report on State Laying Tests 1929/30 in Germany. Jahresbericht über die Staatlichen Wettlegen des Legejahrs 1929/1930. Dr. Otto Bartsch. Editor: Fritz Pfenningstorff, Berlin.
The writer has compiled an inclusive report on all German laying tests during the last laying period. Dr. Bartsch has revised this report, not from a point of view of reporting what hens laid the most eggs, but also with a view to arriving at further conclusions from observations of individual laying tests. He treats moulting, broodiness, causes of death, feeding in connection with laying capacity, winter laying capacity, climatic influences and everything that, in his opinion, could be of influence on the results. Especially interesting is his data concerning the performance of individual birds in flocks and in individual breeds, the results of laying tests in general, according to race and breeds, and the weight of eggs in connection with the laying capacity, a problem which is at present claiming much attention. The reports on duck laying tests in East Prussia will be interesting for many readers. These tests have definitely proved, as did a report from England, that at present the laying performance of ducks is in general 30 per cent. higher than that of hens.
