Bacillary Diarrhea in Fowls by H. Magnusson. Skand. Vet. Tidskrift, Aug. 1928.

In Sweden Bacillary Diarrhea in hens was first observed in 1925, although it probably occurred before that time. The disease should be called „Bird typhoid” and the bacteria which cause it „bacterium gallinarium Klein” after the person who discovered them.

Feeding Standards for Poultry by Eric B. Lomax, B.A., N.D.P. Senior Research Assistant, National Institute of Poultry Husbandry, Newport, Salop. Harper Adams Utility Poultry Journal, 1929, no. 8.

In order that poultry may be fed in an economical manner it is essential that there be standards upon which to calculate the requirements of the bird and that these requirelnents Inay be correctly varied for birds differing in weight and in expected production.

Poultry Breeding and Production by Edward Brown, LL.D., F.L.S. President of the World's Poultry Congresses, 1921, 1924, 1927; Honorary Past-President of the International Association of Poultry Instructors and Investigators; First President of the National Poultry Council (Eng. & Wales). 50s. net two vols. Ernest Benn Limited, Bouverie House, Fleet Street, E.C. 4. Vol. I. Pages 1–408. Plates I–LXVIII. Vol. II. Pages 409–864. Plates LXIX–CIV.

The progress of Poultry Breeding and Production, in every part of the world, during the last half century, has been truly phenomenal. Poultry Breeding was, indeed, practiced on more or less systematic lines even before the Christian era, but as a rather negligible branch of food production. Its importance to-day is world-wide, either as husbandry in connection with agriculture, or on a specialist basis.

The Influence of confinement on the Production of white leghorn pullets by F. C. Bobby. Report from the National Institute of Poultry Husbandry Experimental Farm. The Harper Adams Utility Poultry Journal 1929, p. 471.

1. 1. The experiment confirmed the previous experiment of the winter 1925-1926. Under the conditions of this experiment confined White Leghorn pullets showed a decrease in egg production. The important condition associated with this decrease in eggs was a glass fronted house which prevented any direct rays of sunlight reaching the pullets when confined to the house itself.

2. 2. That the apparent reason for the decrease in egg production is a lack of sunlight or the antirachitic vitamin, which results in a condition resembling rickets among the pullets so confined.

3. 3. This condition in adult stock appears only after the birds have been confined for two-three months. It has occurred in both the experiments of 1925-26 and 1927-28.

4. 4. That the use of an open-fronted house, protected in a suitable way against inclement weather, and at night, is one definite method of obtaining improved results with confined birds.

5. 5. That the use of 2 per cent. Cattle Cod Liver Oil supplies the necessary food accessory, the absence of which appears to result in the decrease of egg production described.

6. 6. That the birds under confinement without a sufficient source of Vitamin „D” are likely to lose body weight, as indicated by the results obtained in this experiment.

7. 7. That the egg weight is not influenced by the differences in management practised in this experiment.
