The critical period for developing a preference for the maternal pheromone in rat feces occurs at 14 to 16 days of age (Leon and Behse, 1977). Non-rat odors such as pure mint or peppermint can be made as attractive as maternal feces to rat pups under the age of 21 days. At that age, simple exposure suffices. A preference is acquired whether the odor is simply presented or pasted on the mother. But the older the pup, the more important the maternal context becomes, and pups up to 33 days old can acquire peppermint preference only if it is presented on the mother. The waning of the response is also much slower for the odor experienced on the mother. After 20 days of age, the rats acquire preferences less easily (Galef, 1982 Galef and Kaner, 1980). Postnatal conditioning to odors is facilitated not...

Between 14 and 21 days of lactation female mice excrete a pheromone in their feces which strongly attracts the young. When the young cease to respond to the emission of pheromone at age 27 days, the female stops releasing it. Males injected with bile from females which have been lactating for 21 days also release maternal pheromone (577). High circulating levels of prolactin are necessary for the pheromone emission (575).
