Nowadays organ explant cultures of mammary tissue are used to study the hormonal control of mammary development in non-ruminants. We have extended this technique to the culture of goat mammary gland.

Nulliparous pure-bred Czech-white female goats with no obvious udder growth before pregnancy were used. They were killed by exsanguination and both mammary glands were removed and put in cold, sterile 0·85% NaCl. Batches of 20 expiants, selected at random, were put into Petri dishes containing 4 ml medium (Waymouth, 1959) and the required hormones. The Petri dishes were incubated at 37 °C under 95% O₂ : 5% CO₂. The secretory status of the expiants was studied histologically and graded according to Barnawell (1965).

The mammary tissue of our goats at weeks 9 and 10 of pregnancy contained collections of
