“…, 2004b). Experiment 1 showed that the motivation of the lamb to explore its mother’s body increased after the tube‐feeding procedure, exposing the neonate to maternal olfactory cues, especially while searching for the teat (Vince, 1984; Vince et al. , 1987), and also to vocal cues (Sebe et al.…”

“…In addition, inactivation of the CoA and the MeA in sheep via local infusion of lidocaine impairs maternal bonding (Keller et al, 2004b). Experiment 1 showed that the motivation of the lamb to explore its mother's body increased after the tube-feeding procedure, exposing the neonate to maternal olfactory cues, especially while searching for the teat (Vince, 1984;Vince et al, 1987), and also to vocal cues (Sebe et al, 2007). The amount of time exploring the mother's body and being groomed did not differ between lambs from the three experimental groups, giving them similar opportunities to be in contact with proximal cues.…”

In sheep, the onset of filial bonding relies on early intake of colostrum. The aim of our work was to describe in the newborn lamb housed with its mother the immediate post-ingestive effects of colostrum intake, in terms of behaviour and brain activity. In Experiment 1, lambs received five nasogastric infusions of colostrum, or saline, or sham intubations during the first 6 h after birth. Mother-young interactions were recorded before and after the first, third and fifth infusions. The activity of the dam and of the young, which diminished over time in all groups, was temporarily increased in both partners just after each intubation procedure. The number of high-pitched bleats was significantly lower in lambs that received colostrum than in the sham group, suggesting soothing or satiating properties of colostrum. In Experiment 2, newborn lambs received a single nasogastric infusion of colostrum or saline 4.5 h after birth, or were sham intubated. Neuronal activation was investigated 1.5 h later for maximum c-Fos activity. Infusion of colostrum and saline induced different patterns of c-Fos-like immunoreactivity in the paraventricular and supraoptic nuclei of the hypothalamus as compared with the sham group. A specific oxytocinergic/vasopressinergic (OT/VSP) cell population in the paraventricular nucleus was activated following colostrum and saline infusion, but not sham intubation. Only colostrum induced the activation of the cortical amygdala and insular cortex, two structures involved in learning, associative processes, reward and emotion. We hypothesize that filial bonding may be triggered through colostrum-rewarded learning/calming processes and that the OT/VSP system may play a role.

“…They may have experienced a functional impairment of their visual or olfactory perception, as Vince et al (1987) found vision to be important in the initial 'teat-seeking' activity and reduced olfactory sensitivity lengthened the time it took for a lamb to suck. Failure of a lamb to suck can either be attributed to the lamb itself or poor ewe maternal behaviour.…”

Relationship between lamb vigour and ewe behaviour at parturition

Maternal behaviour and lamb vigour are both considered major variables affecting lamb survival, but there are few data to describe their relative importance. To investigate the relationship between lamb vigour and maternal behaviour this study compared the behaviour of pure Scottish Blackface lambs with Mule (Bluefaced Leicester O" X Scottish Blackface $ ) lambs, all born indoors. Anecdotal accounts suggested a significant reduction in lamb vigour in Mule lambs, a matter also of significant practical importance given the current increase in Mule numbers. Observations on the grooming behaviour of 32 single or twin-bearing ewes, and on the general activity and udder-seeking behaviour of their lambs were made at parturition. In this study, neither ewe grooming behaviour nor general lamb activity were directly related to lamb sucking success. It was shown that, although Mule lambs had high birth weights and stood as quickly as Blackface lambs, they showed significantly fewer sucking attempts (P < 0-01) and took longer to suck successfully (28 min for Blackface v. 55 min for Mules). The inability of Mule lambs to suck successfully was due to their failure to show proper udder-directed behaviour. These results indicate the importance of considering the behaviour of both ewes and lambs as it would seem that it is not 'poor' maternal behaviour but inappropriate lamb behaviour that is a limiting factor in lamb survival in the Mule breed.

“…Three strategies have been followed to reveal the impact of odour cues in the nursing context: i) the deletion of the offspring's olfactory system and assessment of ensuing consequences (e.g., Kovach and Kling, 1967;Singh and Tobach, 1975;Vince et al, 1987;Hongo et al, 2000), ii) the evaluation of the effects of suppression/restitution of meaningful odorants on the ability to locate and grasp nipples (e.g., Teicher and Blass, 1977;Morrow-Tesch and McGlone, 1990;Varendi et al, 1994), and iii) the demonstration of a link existing between the level of emission of a maternal signal and the rate of offspring response to it (Leon, 1992).…”

Convergent changes in the maternal emission and pup reception of the rabbit mammary pheromone

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
