1. In goats provided with innervated pouches of the abomasum, the intramuscular injection of insulin was followed by a depression of volume‐rate and of the free and total acidity of the secretion. 2. No relation was observed between the degree of hypoglycæmia and the depression of gastric secretion, or between the degree of hypoglycæmia produced by a given dose of insulin and the previous duration of fasting.

“…As the estimated total daily output of acid gastric juice is 5-0 1. (Masson & Phillipson, 1952;Hill, 1960), the pyloric secretion appears to be of little significance in so far as neutralization of the abomasal content is concerned.…”

“…It is known, however, that the herbivores, especially those with ruminant stomachs, secrete considerable amounts of gastric juice daily (Kuznetsova 1950;Masson & Phillipson 1952)-even more than in the non-herbivores-and since the cephalic phase of gastric secretion is either absent or unimportant in the herbivores (Popov 1932 ;Espe & Canon 1937), the voluminous secretion of juice in these species would necessarily require a large production of gastrin. In herbivores too, the concentration of hydrochloric acid in the gastric juice appears to be less than is found in the non-herbivores (Grosser 1905 ;Masson & Phillipson 1952;Duke 1955), suggesting that the acid inhibition of gastrin production described by Dragstedt (1957), Posey, Smith, Turner & Aldridge (1965) and recently reiterated by Grossman (1968) would be less in the herbivores than in the non-herbivores. If, therefore, the herbivores could be viewed as producing more gastrin, it is not improbable that more gastrin would be stored in their gastric antra, particularly if the rate of release of the hormone relative to synthesis is lower in the herbivores than in the non-herbivores.…”

Summary1. The amounts of crude gastrin extract and the gastrin activities of extracts from antral mucosa of several mammalian species have been determined. 2. The yield of crude gastrin powder per gramme wet weight of antral mucosa was greater in goats and rabbits than in cat, dog, man or pig. 3. Statistical differences do not appear to exist between the potencies of gastrin from the various species. The potencies of the powders were within the ranges 1X2-1 8 ,ug porcine gastrin 1I/mg with the exception of the extract from frozen dog antra (08 ug/mg). 4. During prolonged freezing of animal antra and consequent thawing before extraction, significant losses in gastrin activity occurred in the dog. 5. The amounts of gastrin activity per gramme wet weight of antral mucosa from herbivores (goat, rabbit and cattle) were greater than those from nonherbivores (cat, dog, man and pig). IntroductionThe isolation of the hormone gastrin, the elucidation of its structure and the more comprehensive characterization of its activities have now placed the endocrine function of some cells of the gastric antrum beyond doubt. The work in the Pavlovian School reported by Babkin (1928) and investigations of other workers have shown that meat extracts and some other constituents of food, stimulate the release of the antral hormone, thus the gastrin content of the antral mucosa may reflect the dietary habit of the animal. The present paper is concerned with a comparative study of the gastrin activity extracted from the antral mucosa of various mammals including carnivores (dog and cat), herbivores (cattle, rabbit and goat) and omnivores (hog and man).
