“…The goat hiding phase is more variable, but generally, they are known to have an especially short hiding phase among hider species (Lent 1974;Lickliter 1984). During hiding in the first week, Bungo et al (1998) reported 5.64 nursing bouts per hour. Thus, goat mothers and kids should interact vocally more often than fallow deer, resulting in a more advanced level of mutual vocal recognition.…”

Parent-offspring recognition can be essential for offspring survival and important to avoid misdirected parental care when progeny mingle in large social groups. In ungulates, offspring antipredator strategies (hiding vs. following) result in differences in mother-offspring interactions, and thus different selection pressures acting on the recognition process during the first weeks of life. Hider offspring are isolated and relatively stationary and silent to avoid detection by predators, whereas follower offspring are mobile and rapidly mix in large social groups. For these reasons, hiders have been suggested to show low offspring call individuality leading to unidirectional recognition of mothers by offspring and followers high offspring call individuality and mutual recognition. We hypothesised that similar differences would exist in hider species between the hiding phase (i.e. unidirectional recognition) and the phase when offspring join social groups (i.e. mutual recognition). We tested these predictions with goats (Capra hircus), a hider species characterised by strong mother-offspring attachment. We compared the individuality of kid and mother calls, and the vocal recognition ability, during the early phase of life when kids are usually hidden and later when kids have typically joined social groups. Contrary to our predictions, we found that both kids and mothers had individualised contact calls and that mutual recognition existed even during the hiding phase. The large differences in the duration of the hiding phase and in the rate of mother-offspring interactions (possibly partially driven by domestication in some species) probably cause variations among hider species in the mother-offspring recognition process.

“…On commercial farms, calves can be weaned as early as 3 months of age (Guinness et al 1979) or as late as 12 months. Ideally, the optimum weaning age of farmed ruminant animals should take into account the suckling, nursing, and foraging behaviour of the offspring and their respective dams (Bungo et al 1998).…”

Red deer (Cervus elaphus scoticus) hinds were confined before parturition in 20 × 30 m earth-floored pens and offered freshly cut legumegrass mixed pasture (Experiment 1) or lucerne hay (Experiment 2). In Experiment 1, four hinds were placed in a single pen; all parturitions took place within 24 h. Animals were monitored by a single observer for 24-h periods twice weekly for 10 weeks. Number of daily suckling episodes increased with age while their duration decreased. Consumption of forage started around the fourth week and, by weaning, calves had spent an average of 105.5 min eating forage and 44.2 min ruminating daily, compared with hinds, which consumed forage for 6.05 h and ruminated for 1.77 h per day. In Experiment 2, 24 hinds and their calves were confined in four pens for 12 weeks. Four observers each monitored the activities of a randomly chosen calf from 0800 to 1330 h and from 1430 to 2000 h. Activities were analysed as proportions of total activity using linear and quadratic regressions. Time spent suckling increased until Day 26 (110 seconds, in a total of three bouts), decreasing to 13 seconds (in a total of eight bouts) by Day 73. Most of the hinds (70%) allonursed (nursing a calf other than its own), some as soon as 2 days post-partum. Forage consumption by the calves decreased from 37.1 s at 8 days to 12.6 and 17.1 s at 59 and 73 days, respectively. The regression equation for time spent suckling (proportion of total activity) against calf age (days) showed a quadratic effect: y = 0.76 -0.026 day + 0.00023 day 2 (R 2 = 0.797), whilst time spent eating forage showed an opposite quadratic trend: y = -0.17 + 0.28 day -0.0002 day 2 (R 2 = 0.761).

“…For example, in pigs and sheep, species in which females are frequent nursers, neonatal inability to gain colostrum in the first days is linked to an increased mortality [1,8,10,11]. However, in such species, the young may compensate for initial failure to suck by taking advantage of nursing episodes soon after (for example, the average frequency of suckling/hour during the first week after birth: pig, 1/h [24]; sheep, 1.2/h [13]; foal, 4/h [7]; kids, 5.6/h [4]). …”

Immediate postnatal sucking in the rabbit: Its influence on pup survival and growth

-This study was aimed at characterising the impact of immediate postnatal sucking on pup survival and development. The interactive effects of postnatal success with the day 0 weight of pups, the nest-access regimen (controlled or free) or parity of females was investigated. Pups (n = 900) were categorised according to their initial ingestion of colostrum. In primiparous does: (1) pup mortality between d0-d10 was higher for unsuccessful than for successful early suckers; (2) lighter d0-weight reduced survival for unsuccessful but not for successful pups; (3) free nest-access of females annihilated the survival advantage fostered by the initial sucking success. In secondiparous does, these impacts waned. Finally, whatever the does' parity, only d0-weight influenced pup weightgain between d0-21. Thus, pup survival seemed to depend (at least in primiparae) on their ability to suck right after birth, and to display a pattern of energy saving without being disturbed by the females' nest entries. rabbit (Oryctolagus cuniculus) / newborn / sucking / colostrum / survival / growthRésumé -La tétée initiale du lapereau : influence sur la survie et la croissance.
