Abstract

The technique employed a bovine pituitary preparation ("NIH-P-B 2") as antigen. There were occasional cross-reactions with sheep prolactin, but not with other pituitary hormones. The prolactin level in the blood was more closely related to season of the year than to stage of lactation or milk...

Abstract

In the male pig the values varied from 0.94 to 1.61 µg per 100 ml plasma and were 7 and 11 times higher, respectively, than in castrated and female animals. Values increased with age. The concentration measured in a bull was 0.59 µg per 100 ml plasma.

Abstract

A biological assay technique using the rabbit uterus, sensitive to less than 10 µg per litre of milk, showed residues of 12 μg/litre in the first two milkings after i/v injection of cows with 50 mg chlormadinone acetate, but subsequent milkings were negative. No residues were detected after i/m...

Abstract

Radio-immunological methods were found suitable for the detection of ICSH and prolactin in male animals. In young bulls levels of 1 ng/ml ICSH and 10-200 ng/ml prolactin were recorded in plasma Levels of these hormones in steers were higher than in bulls. The physiological significance of prolactin ...

Abstract

The techniques of radio-immunological assay described by Kwa & Verhofstad (1967) for the rat and by Bryant & Greenwood (1968) for ruminants are based on the binding of serum prolactin by anti-serum against prolactin, labelled with radio-iodine. In this preliminary report the results of...

Abstract

Observation of the eosinophile leukocytes of the circulating blood is suitable for detecting the reaction of the host to certain acute "shocks" which act on the pituitary-adrenal system. A suitable method for cattle and pigs is described. Taking account of day-to-day variations, the results are...
