The F. 1 generation showed good laying capacity (average 189,5 eggs). The laying capacity of the F. 2 hens was not so good (136,6 eggs). In the F. 3 generation the production was 127,8 eggs, accompanied by a great variability of the hens viz. from 32 to 211 in 53 hens.

Harmful Action of Fatty Fishmeal. Deutsche Landwirtschaftliche Geflügelzeitung, April, 1931.

Five groups of chickens were fed for a period of 8 weeks with the same basal ration and fishmeal of varying fat content. The chickens fed with fishmeal of 1,5% fat were the heaviest at the end of the test period and per pound body weight had consumed the least food. Among the birds fed with fishmeal of 18% fat content there was a death rate of 23%. A high percentage of fat also left much to be desired in connection with the colour of the plumage, the development of the body and the formation of yellow pigment in the legs.

This book of Römer and Weinmiller occupies a special place among literature dealing with poultry breeding. Leading experts in poultry breeding research have created it, so that it is not surprising that the first edition was sold out within a very short time. The new edition has been valuably supplemented and revised. All kinds of questions which engage the attention of poultry keepers and breeders are fully and clearly treated and reference is made to the most recent data obtained from practical and scientific research. Housing, feeding, utility breeding, profit making, breed questions, hereditariness, organisation are treated in the same thorough manner. From the development of the chicken in the egg to the attractively composed sales advertisement one can find everything that the breeder or keeper of the present day needs.
