“…In the European rabbit, all these ways have been used to examine pup responses to odour cues emitted by the female: i) the alteration of the pup olfactory system severely disturbs nipple localization and oral seizing (Schley, 1976;Distel and Hudson, 1985;Hudson and Distel, 1986), ii) the washing or selective covering of mammary areas inhibit the attraction and/or sucking behaviour of pups (Schley, 1976;Müller, 1978;Hudson and Distel, 1983;Coureaud et al, 2001), and iii) variations in the female's physiological state, due to postpartum physiological changes or seasonal factors, induce modifications in odour emission and pup behaviour Distel, 1984, 1990;GonzalezMariscal et al, 1994;Coureaud and Schaal, 2000).…”

“…Regarding the emission side, one may recall first that the attractive factors released from the abdomen by lactating females seem tightly related to lactational physiology (Hudson and Distel, 1984;Gonzalez-Mariscal et al, 1994;Coureaud and Schaal, 2000). Thus, the drop of the MP in late lactation-milk may co-vary with the alterations in maternal physiology.…”

Lactating rabbit females emit volatile odour cues that trigger specialized motor actions leading to sucking. But the activity of these cues may change with advancing lactation. Here, we tested this possibility in three experiments. In Exp. 1, we assessed whether 2-day-old pups respond differently to the odour of milk from females in early (day 2) as compared to late (day 23) lactation. In Exp. 2, a compound bearing pheromonal properties, the Mammary Pheromone (MP), was dosed in these milks to assess whether its concentration is correlated with behavioural activity. In Exp. 3, the responsiveness to a constant level of MP was compared in d2 versus d23-pups. Run on 240 pups, the assays showed that a) the milk activity declines between d2 and d23 of lactation; b) during this same period, the concentration of the MP decreases in milk; c) the MP itself becomes less active to elicit oral grasping in pre-weaning pups than in newborns. These results indicate that the MP is active during the period when pups are exclusively dependent on milk. The convergent changes in emission and reception of this pheromone may sequentially warrant that pups are first attracted to the mammae, and then that they progressively disinvest the mother as they begin to eat solid food and to be attracted by other conspecific

“…A possible role for odor cues has often been found, even in human infants [26,65,84,108,113]. It has been proposed that the dam's manipulations of pups during normal mother/infant interactions may be how rat pups form an attraction to the maternal odor and an attachment to the dam [30].…”

INTRODUCTIONSocial bonds are made up of numerous subsystems mediating the overall social relationships that develop between infants and caretakers. The effects of an infant's formation of early life relationships and its social interactions with caretakers are known to last well in to adulthood with both beneficial and harmful effects [28,35,70]. In our laboratory, we study the development of social relationships between infant rats and their dams, sires, and littermates using an isolation, reunion, and re-isolation test paradigm.Infant rats emit ultrasonic vocalizations (USV) in a variety of situations, including as a response to isolation, physical manipulation, and thermal and olfactory challenge [1][2][3]6,19,25,46,79,80,82,97]. Many researchers have used the presence and absence of these sounds to make inferences about the internal state of the rodents, e.g., isolation-induced USV's have often been called "distress vocalizations" [29,76,78].The isolation-induced vocalization of a rat pup is modulated both by current social interactions and by the pup's rearing experience. This modulation of USV by social interactions provides a paradigm for investigating the neurobehavioral mechanisms underlying acquisition and expression of infant attachment. What is maternal potentiation of isolation-induced vocalizations of infant rats?Maternal potentiation of ultrasonic vocalization occurs when, after a brief contact with the dam, isolated infant rats produce USV at a rate significantly higher than they would during an isolation not preceded by dam contact. Although the definition may seem of narrow interest, there is a growing belief that the potentiation phenomenon has broad applicability for the study of early life social relationships in many species. But before going further, the reader needs to understand the usual test paradigm in our laboratory.Developmental Psychobiology, Unit 40, New York State Psychiatric Institute, 1051 Riverside Dr. NY, NY 100032, Tele 212-543-5695, Fax 212-543-5467, hns1@columbia.edu Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

The litter is allowed to adapt to her removal for ~15-20min in the home cage on a thermoregulated heating pad. Then, each pup is tested in turn. The pup is picked up and placed alone in a clean polycarbonate rectangular box (18 × 21 × 20 cm) at room temperature. The test consists of three periods, which can range from 1-5min in length (3mi...

“…In rodents, there is indeed a reciprocal regulation of responsiveness to stress between mother and offspring (Walker et al, 2004). For example, dietary influences are critical in the modulation of the stress response and it was shown that olfactory signals were essential in the orientation to the nipples in several species of rodents (Blass & Teicher, 1980; Coureaud & Schaal, 2000; Gerling & Yahr, 1982). By reducing olfactory abilities, early bilareral naris occlusion could thus have important functional repercussions on mother–pup interaction and notably on the offspring's suckling behavior.…”

The effects of short-term bilateral naris occlusion (inducing olfactory deprivation) on mother-pup interactions, suckling behavior and hormonal status during post-natal development in Wistar rats were studied. Bilateral naris occlusion was performed on 8-day-old rat pups and its effects were evaluated at Day 9 and at Day 15. The narins opened spontaneously between Day 12 and 14. Olfactory-deprived pups exhibited a greater level of corticosterone at both ages versus untreated or sham animals. Olfactory deprivation via naris occlusion, in young rats, alters mother-pup interactions with a decrease in the duration of mother-pup retrieving and an increase in pup licking. Olfactory-deprived pups showed also a lower mean duration of nursing and a decrease in nipple attachment, which appeared related to difficulties in finding the nipple. Olfactory-deprived pups had difficulty recognizing their nest. These behavioral alterations were accompanied by a diminution in milk ingested and growth retardation associated with a reduced level of thyroxin at both 9 and 15 days of age.
