    | Contributor(s):: Christopher J. W. McClure, Benjamin P. Pauli, Julie A. Heath

    Despite common use, the efficacy of artificial breeding sites (e.g., nest boxes, bat houses, artificial burrows) as tools for monitoring and managing animals depends on the demography of target populations and availability of natural sites. Yet, the conditions enabling artificial breeding sites...

  3. Artificial rearing affects piglets pre-weaning behaviour, welfare and growth performance

    | Contributor(s):: Schmitt, Océane, O'Driscoll, Keelin, Boyle, Laura A., Baxter, Emma M.

    One strategy adopted on farms to deal with managing large litters involves removing piglets from their mothers at seven days old to be reared in specialised accommodation with milk replacer. Effects on piglet behaviour, growth and some aspects of welfare were evaluated in this study by comparing...

  4. Can body nosing in artificially reared piglets be reduced by sucking and massaging dummies?

    | Contributor(s):: Frei, Daniela, Würbel, Hanno, Wechsler, Beat, Gygax, Lorenz, Burla, Joan-Bryce, Weber, Roland

    Selection for hyper-prolific sows has substantially increased litter size. Consequently, the number of piglets in a litter may exceed the number of functional teats. To solve this problem, surplus piglets may be removed from the sow 2 days after birth and raised artificially. However, these...

  5. Gentling and welfare of lambs

    Full-text: Available

    | Contributor(s):: M Caroprese, L Taibi, V Franco, M Musto, A Muscio

    Gentling e benessere dell’agnello. Al fine di valutare l’effetto delle cure dell’operatore sul benessere dell’agnello allattato artificialmente è stata effettuata una prova della durata di 7 settimane condotta su 64 agnelli di razza Comisana. Gli agnelli in...

  6. Comparison of the behaviour of piglets raised in an artificial rearing system or reared by the sow

    | Contributor(s):: Rzezniczek, M., Gygax, L., Wechsler, B., Weber, R.

    Over the last 15 years, rising sow fertility has led to a considerable increase in litter size. As a consequence, the number of live born piglets may outnumber the number of functional teats, and surplus piglets are removed from the sow at the age of 3-6 days and fed with artificial milk. The...

  7. Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows

    | Contributor(s):: Wagner, K., Seitner, D., Barth, K., Palme, R., Futschik, A., Waiblinger, S.

    We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth...

  8. Filial attachment in sheep: similarities and differences between ewe-lamb and human-lamb relationships

    | Contributor(s):: Nowak, R., Boivin, X.

    Animals develop relationships with intra- and interspecific partners, including humans. In some cases this can lead to strong emotional bonds indicating the existence of attachment. The sheep is well known to develop various forms of social attachment (mothers towards young, lambs towards...

  9. Abnormal behavior in caged birds kept as pets

    | Contributor(s):: Hoek, C. S. van, Cate, C. ten

    There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

  10. The welfare implications of large litter size in the domestic pig II: management factors

    | Contributor(s):: Baxter, E. M., Rutherford, K. M. D., D'Eath, R. B., Arnott, G., Turner, S. P., Sandoe, P., Moustsen, V. A., Thorup, F., Edwards, S. A., Lawrence, A. B.

  11. Effects of early maternal separation of lambs and rearing with minimal and maximal human contact on meat quality

    | Contributor(s):: Napolitano, F., Caroprese, M., Girolami, A., Marino, R., Muscio, A., Sevi, A.

    The present study aims to assess the effect of gentling on behaviour and meat quality of lambs. Thirty-two Comisana lambs were divided into four groups of eight animals: ER (ewe reared), AR (artificially reared) and the corresponding gentled groups ERG and ARG. The provision of human contacts...

  12. Cross-sucking and other oral behaviours in calves, and their relation to cow suckling and food provision

    | Contributor(s):: Margerison, J. K., Preston, T. R., Berry, N., Phillips, C. J. C.

    Abnormal oral behaviour in calves is believed to develop when there is a lack of opportunity to suckle, but it is unclear whether they need access to their mother or whether a multiple suckling system will suffice to prevent this behaviour from developing. Therefore, in an initial experiment, the...

  13. Effect of gradual transition from maternal to reconstituted milk on behavioural, endocrine and immune responses of lambs

    | Contributor(s):: Sevi, A., Napolitano, F., Casamassima, D., Annicchiarico, G., Quarantelli, T., Paola, R. de

    18-24 h after parturition, 20 Comisana lambs were separated from their dams and were subsequently offered a commercial milk substitute (Sub) or were subjected to a gradual transition from maternal to reconstituted milk over 10 days (Mix). Lambs had free access to milk for 3 h a day. A further 10...

  14. Influence of artificial vs. mother-bonded rearing on sucking behaviour, health and weight gain in calves

    | Contributor(s):: Roth, B. A., Barth, K., Gygax, L., Hillmann, E.

    In artificial rearing, calves are often fed via an automatic milk feeder and have no opportunity to perform natural sucking behaviour. The majority of these calves show abnormal oral behaviours (e.g. cross-sucking). Furthermore, diseases are also a main problem in artificial rearing of calves,...

  15. Maternal presence limits the effects of early bottle feeding and petting on lambs' socialisation to the stockperson

    | Contributor(s):: Boivin, X., Boissy, A., Nowak, R., Henry, C., Tournadre, H., Neindre, P. le

    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 (n=48)...

  16. The presence of the dam affects the efficiency of gentling and feeding on the early establishment of the stockperson-lamb relationship

    | Contributor(s):: Boivin, X., Nowak, R., Terrazas Garcia, A.

    This experiment investigates how the maternal presence influences the effect of additional human contact in early age on the reaction of lambs to their stockperson. 40 twin-born lambs were involved in this experiment during their first 4 days of life. 10 pairs of twins were reared artificially...

  17. Imprinting technique, and intensive socialization early in the foal

    | Contributor(s):: Gonzalez del Pino, F., Escalante, F., Wilde, O. R.

    Imprinting is the technique of nursing an animal like an individual of his own species. This includes carrying out natural handling of the foal from the moment of birth and during the subsequent days, modifying its personality. This learning process only happens in a brief sensitive period after...

  18. Hand-feeding and gentling influence early-weaned lambs' attachment responses to their stockperson

    | Contributor(s):: Boivin, X., Tournadre, H., Neindre, P. le

    45 ewe lambs were artificially reared from multinippled buckets in groups of 3. All the lambs were trained by a stockperson (S1) to suck from the bucket (4.4+or-0.3 sessions of 3 min per animal for the first 2 days of life). Subsequently, 15 lambs received no further human contact (T0). 15 other...

  19. Abnormal behaviour of piglets reared in individual incubators

    | Contributor(s):: Hutton, R. C., Wood-Gush, D. G. M.

    Abnormal behaviour patterns were observed in piglets weaned from their mother 1 day after birth and reared artificially in small individual incubators. The incubators were plastic bins, 0.057 m3 in size, with a window at the front through which a nipple-drinker provided feeds of Carnation milk at...

  20. An artificial sow to investigate the behaviour of sucking piglets

    | Contributor(s):: Jeppesen, L. E.

    A dummy sow and feeding system was developed to rear piglets from 24 h of age to at least 3 wk. The dummy sow incorporated particular features associated with the real sow which appeared to stimulate the development of normal feeding behaviour in the form of nuzzling and sucking. Good growth...
