German Egg Laying Trials. Anon. Harper Adams Utility Poultry Journal, Vol. 21, 1936, p. 472.

The German Egg-Laying Trials are divided into two types as inEngland: (1) tests in which the individual birds are selected by the competitors themselves for entry, and (2) flock tests, the birds being selected by an officialof the agricultural association. These trials are held separately in five centres for each. A total of 1,974 birds were entered, 76·5 per cent. of the entriesbeing White Leghorns. Details of rations and production are given. Diseases of the reproductive and urinary systems accounted for 31 per cent. of the deaths. Virus diseases, including leucomyelosis (presumably lymphomatosis and Ieucaemias) accounted for 21 per cent. and digestive troubles for 16·4 per cent.
