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.

The statistical results of two experiments are in rather close agreement.

Are Oats harmful to Fowls? Dangers of its Anti-vitamin questioned. Norman D. Kay. Poultry, Aug. 30, 1930.

In „The Science of Life”, recently published Huxley and Wells discuss the dangers of a diet lacking in vitamin D. On page 710 they say: „It appears that in some cereals there is an „antivitamin”, which in some way neutralises vitamin D. Oatmeal contains such a substance and if the staple carbohydrate is oatmeal, more vitamin D will be neaded than if it is wheatflour or rice”.

Breeding as Affecting Egg Production.

The work under this project this year is a continuation of that carried on the previous year. The progeny of Cocks 113, 114, 115, and 116, were trapnested during the year. Cock No. 116 is the outstanding breeder, none of his pullets laying less than 100 eggs up to October 1, and 58 per cent of them laying over 180 eggs. Pullets hatched in the spring of 1927, are being trap-nested this year, but their records are not complete. Other pullets which were hatched in the spring of 1928 are being held and will be trap-nested the coming year. In addition to breeding White Leghorns for increased egg production, breeding work is being done using White Rocks and Barred Rocks in an endeavor to establish a White Rock high-egg producing strain.
