“…Nonetheless, in sheep, the results of Terrazas et al (2002) show that if both the lamb's own mother and an alien mother are anosmic, they do not behave differently. Furthermore, it is well established that anosmic goats display similar acceptance behaviours towards alien kids as intact goats do towards their own kid (Romeyer et al, 1994a;Herná ndez et al, 2004). Therefore, our present results suggest that newborn kids first develop a preference for behaviours indicative of maternal acceptance, before developing the ability to recognise individual characteristics of their dam, as it is the case in lambs.…”

“…It is well documented that in ewes and does, anosmia induced by zinc sulphate during pregnancy prevents the establishment of olfactory recognition of the neonate by its mother and the development of selective maternal care. As a consequence, in both species, anosmic mothers display maternal acceptance towards an alien young as well as towards their own young (Romeyer et al, 1994a;Herná ndez et al, 2004;Lé vy et al, 2004). The goats had been rendered peripherally anosmic by irrigation of the olfactory mucosa with a 1.5% zinc sulphate solution 1 year before this study, according to the method of Romeyer et al (1994a).…”

“…Therefore, we investigated whether 8-, 12-and 24-h-old kids displayed a preference for their mother in a two-choice test and, if so, whether this initial preference depended on differences in maternal selective behaviour between the own and the alien dam, as reported in sheep . To assess this question, we studied the response of 12-h-old kids given the choice between two anosmic mother goats, both of which displayed acceptance behaviours, since peripheral anosmia induced before parturition by irrigation of the nostrils with zinc sulphate prevents the development of maternal selectivity (Romeyer et al, 1994a;Herná ndez et al, 2004). Finally, we also investigated whether the size of the testing pen could influence the display of an early preference for the mother; we compared the performances of 8-h-old kids tested in a pen similar to that used for lambs, with that of kids tested in a smaller pen and placed closer to the dams at the beginning of the test.…”

Preference of 12-h-old kids for their mother goat is impaired by pre-partum-induced anosmia in the mother

We investigated whether kids were able to discriminate their own mother from an alien one in a two-choice test on the day of birth when they had access to acoustic, visual and olfactory cues from their mother, and whether this discrimination depended on the selective maternal behaviour of the mother (i.e. exclusive nursing of own kids). When given the choice between their own mother and an alien equivalent dam, 8-h-old kids did not show a significant preference for their dam, whereas 12-and 24-h-old kids did. When given the choice between their own and an alien mother that were both non-selective because they had been rendered peripherally anosmic by irrigation of the nostrils with zinc sulphate, 12-h-old kids did not show a significant preference for their mother. These results are similar to those reported in sheep and may suggest that the contrast of behaviour between their own and an alien mother existing in normosmic does is important for discrimination of dams by kids at this age. Finally, testing 8-h-old kids in a smaller enclosure resulted in some improvement of their performance, although they still failed to display a significant preference for their mother. On the whole, kids are able to discriminate between their own and an alien mother goat as early as previously reported in lambs. The impairment of this ability when mothers are anosmic and not selective suggests that acceptance behaviours displayed by the mother may serve as one of the cues orientating the choice of the kid when given the choice between intact mothers. Finally, the present results do not suggest the existence of fundamental differences in the establishment of a preference for the mother between lambs, which are followers, and kids, which are hiders.

“…To assess the ability of does to recognize their kids, mothers underwent a test of selective nursing for olfactory discrimination (Hernandez et al, 2004) at 4 h post partum and a two-choice test of discrimination excluding olfactory cues (Poindron et al, 2003) at 8 h post partum. These two separate tests were carried out to take into account the fact that like sheep, goats use two separate systems of discrimination, depending on the distance at which recognition operates.…”

We investigated whether undernutrition during the second half of pregnancy impaired the behaviour of does and their kids at parturition and early mutual recognition. Twenty-two control and 22 underfed mixed-breed, multiparous dairy goats were used, together with their respective kids (control,n= 31: nine singles, 16 twins and six triplets; underfed,n= 32: 11 singles, 18 twins and three triplets). Undernutrition involved limiting protein and energy intake at 70% of the nutritional requirements for maintenance and foetal growth from day 70 of pregnancy until birth. The behaviour of mothers and their two first-born kids was observed for 90 min from the birth of each kid. Maternal olfactory recognition of the kid was assessed at 4 hpost partumby testing selective nursing behaviour. Non-olfactory recognition was assessed at 8 h in a two-choice test excluding olfactory cues. In kids, preference for the mother was assessed in a two-choice test at either 12 or 24 hpost partum. Bodyweight of does and kids were lower in the underfed group up to 2 weekspost partum. At parturition, licking, maternal bleating frequency and latency to nursing did not differ between nutritional groups. Control kids were faster than underfed kids to stand, search for and reach the udder, but underfed kids bleated more and tended to spend more time at the udder. Both control and underfed does accepted their own kid and rejected the alien in the selectivity test at 4 h. In contrast, at 8 hpost partum, only control goats showed a significant preference for their own kid in the non-olfactory recognition test. Both control and underfed kids showed a preference for their own mother at 12 and 24 h and undernutrition during pregnancy had little influence on the performance of kids. However, 12 h-old underfed kids tended to be less active than control kids and visited their own mothers less than control kids. There were no significant correlations between the behaviour of the mother or of the kid at parturition and their performance in the discrimination tests. Overall, undernutrition in the second half of pregnancy appears to be more detrimental for the behaviour of the mother than for the kid. Furthermore, it has more impact on the establishment of maternal non-olfactory recognition than on maternal care at parturition or the establishment of maternal selectivity.

“…As in ewes, a main characteristic of mother–young relationships in female goats is the early establishment of a long‐lasting exclusive bond with their litter (Poindron et al, 2007). Females accept only their own goat kids for suckling and actively reject any alien kid that tries to suckle (Hernández et al, 2004). This exclusive mother–young bond also affects maternal peripheral OT release in response to suckling.…”

Milk let‐down in goats can be influenced by the type of stimuli applied or to which goats are exposed during suckling and hand milking

The present experiments on goats were conducted with the aim of verifying (a) whether the identity of the goat kids can affect the characteristics of milk let-down during suckling (Study 1) and (b) whether the presence of the goat kids may improve the milk let-down during hand milking (Study 2). In Study 1, 16 lactating goats with twins and 12 with single kids were used. Dams with single goat kids ejected more milk when suckling their kids at Days 5 and 20 of lactation, than when suckling aliens. Dams with twins ejected more milk when suckling their own kids than aliens only at Day 5 of lactation. Taking into account all the dams, they ejected more milk with more fat, protein, and lactose during suckling their own litter than when suckling aliens. In Study 2, when dams (n = 13) were hand milked in the presence of their own litter or in its absence, they ejected more milk with more fat, protein, and lactose than when milked in the presence of alien kids. We conclude that milk let-down in goats can be influenced by the type of stimuli applied or to which they are exposed to during suckling and milking.
