Abstract

Mothered herbivores are more fearful towards humans than those reared artificially, However, in previous studies, both human contact and maternal environment factors have been confounded. This paper investigates the influence of early human contact (petting, bottle feeding) given to lambs reared artificially in the presence or absence of the dam, on their socialisation to the stockperson. Forty-eight lambs were studied. From day 1 of age until 7 weeks of age (weaning), half the lambs (M1) were individually reared in the presence of their dam and one twin lamb behind a grid. At weaning the dams were removed. The rest of the lambs (M0) were reared only in the presence of their twin lamb behind the grid. In each M0 or M1 group, half the animals received human contact until 6 days of age (H1), and the other half were not handled (H0). Later, they had no visual contact with humans during husbandry. Response to the stockperson was measured during the initial sessions of human contact. during tests in the rearing pen (at 4 and 9 weeks of age) and in a test pen at 5 and 10 weeks of age. In addition, responses to a novel object in the rearing pen at 3 and 8 weeks of age, and preference for the stockperson or their familiar conspecific(s) (no dam after weaning) at 6 and 11 weeks of age were also measured. During the sessions of human contact, lambs stayed in contact to the stockperson whatever their maternal environment. Later, whatever the age, H1 lambs approached the stockperson more quickly (P < 0.01) and interacted for longer (P < 0.05) in the different tests than H0. However, M0H1 lambs approached the stockperson (P < 0.05) more than the other lambs, even in the choice test (P < 0.01). In addition, M0 animals approached the novel object more than M1 lambs at 3 weeks of age (P < 0.05), but not after weaning, and tried less to rush out into the conspecific(s)'s pen at any age (P < 0.01). The results clearly show the effect of the maternal environment on lambs' socialisa

Abstract

We assessed the influence of mother ewes (Ovis aries) on the development of their lambs' discriminative social interactions. Experiment 1: twin lambs in one condition were housed with their mother in small groups (M lambs), while twins in a second condition were separated from their dam after birth and artificially reared together (AR lambs). Lambs' preference for their twin (T) versus a familiar penmate (F) was investigated at 4 weeks of age, using a simultaneous two-choice test. Experiment 2: 4-week-old mothered and artificially reared lambs were exposed repeatedly to a contact partner for long sessions over a 5-day period (the dam was absent during these contact sessions). Discrimination between the encountered partner (E) versus an unfamiliar individual (U) was assessed in a series of two-choice tests and pair distress tests. In the first experiment, mothered lambs responded discriminatively to T versus F individuals whereas artificially reared lambs did not display a preference. This suggests that the presence of the mother is necessary for the establishment of discriminative interactions between twins. Ewes may directly or indirectly foster proximal contact and thus mutual familiarisation between their twins. In the second experiment, lambs displayed no preference when given the choice between E and U individuals. Nevertheless, when paired with an E partner in a small cage, AR lambs, but not M lambs, bleated less than when tested with a U partner, which suggests that the former partner was recognised. Lack of discrimination of the E partner by M lambs may result from significantly lower investigation of the contact partner during their encounters, compared to AR lambs. Thus the dams affected their offspring's socialisation with peers even though they were not physically present during the encounters. Overall, these results show that the dam plays a prominent role in the development or her offspring's social relationships with siblings as well as with ot

Abstract

This book presents cross-discipline studies covering aspects ranging from animal science to social/consumer sciences and psychology, with the aim to collect and disseminate information promoting the continuous enhancement of animal welfare by improving stakeholders’ perception of animal welfare. Although animal welfare is about how the animals perceive the surrounding environment, the actual welfare of the animals is dependent on how the stakeholders perceive and weigh animal welfare. The stakeholders can, either directly (i.e., through stock-people interaction with the animals) or indirectly (e.g., when retailers and consumers are willing to pay more for high welfare animal-based products), affect the way animals are kept and handled.
