Vitamin D for Chicks. The Effects of an insufficient Supply of Vitamin D on Growth of the Skeleton and internal Organs of Chickens. E. J. Sheehy and K. Sheil. Royal Dublin Society, Proceedings Vol. 20, No. 16.

In this paper the importance of supplying Vitamin D to chicks for the purpose of preventing leg weakness, unthriftiness, and crooked breast is emphasised.

Value of Agglutination-Test. - Der Wert der Agglutinations Methode bei der weissen Ruhr. Dr. Sachweh, München. Berliner Tierärztliche Wochenschrift, 1931, p. 845.

A number of chickens were subjected, every three months, to the agglutination test. During this test it appeared that the agglutination titer varied considerably. All animals, of which a great number reacted positively at the beginning of the test, reacted negatively at the end thereof. This made it possible to comprehend the strongly varying results of the different tests. A group of 400 positive reacting hens gave healthy chicks. The wide advertising of the rapid blood test results in the poultry farmers making their own researches, and owing to the varying results obtained, it forces them to attach no value thereto.
