  1. Behaviour of calves at introduction to nurse cows after the colostrum period

    Contributor(s):: Vaarst, M., Jensen, M. B., Sandager, A. M.

    In traditional housing systems for dairy herds, calves are very often placed in single boxes and fed milk from a bucket, which may lead to abnormal behaviour. In organic herds, for whom the aim is optimal animal welfare, there is interest in using suckling systems, where the calves have the...

  2. Birth weight variation in the domestic pig: effects on offspring survival, weight gain and suckling behaviour

    Contributor(s):: Milligan, B. N., Fraser, D., Kramer, D. L.

    In domestic pigs, litter-mates often vary considerably in birth weight. To examine whether this size variation influences piglet survival, weight gain and suckling behaviour, we experimentally manipulated the number and size distribution of litter-mates in 51 litters. Litters were small (eight or...

  3. 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...

  4. Cross-suckling and nursing synchronisation in group housed lactating sows

    Contributor(s):: Maletinska, J., Spinka, M.

    Group housing systems for lactating sows with piglets enable the animals to behave more naturally than traditional restrictive systems. However, piglets may occasionally suckle from other sows than their mother. The influence of litter size, age of the litter, mother parity, piglet gender and, in...

  5. Dimensions of maternal behaviour characteristics in domestic and wild x domestic crossbred sows

    Contributor(s):: Spinka, M., Illmann, G., Jonge, F. de, Andersson, M., Schuurman, T., Jensen, P.

    We examined the maternal behaviour of seven domestic and seven wildxdomestic primiparous sows during 10 days post partum at the Wageningen Agricultural University, Neatherlands during April-June 1997 to investigate two questions: (1) Did maternal behaviour change during domestication? (2) Can the...

  6. Effect of milkflow rate and presence of a floating nipple on abnormal sucking between dairy calves. (Special issue: Suckling)

    Contributor(s):: Loberg, J., Lidfors, L.

    The aim of this study was to investigate if access to an artificial teat, compared with an open bucket, would decrease abnormal sucking in calves held in pairs, and if the calves would perform less abnormal sucking if they spent more time drinking or sucking milk. Sixteen calves of Swedish Red...

  7. Effects of amount of milk, milk flow and access to a rubber teat on cross-sucking and non-nutritive sucking in dairy calves. (Special issue: Suckling)

    Contributor(s):: Jung, J., Lidfors, L.

    The aim of this study was to test the effects of different amounts of milk, rate of milk flow, and access to a teat after milk intake on non-nutritive sucking on an empty teat and on cross-sucking on other calves in Bos taurus dairy calves. An additional aim was to test if calves prefer to...

  8. Effects of different suckling systems on milk production, udder health, reproduction, calf growth and some behavioural aspects in high producing dairy cows - a review. (Special issue: Suckling)

    Contributor(s):: Krohn, C. C.

    This article discusses the consequences of different suckling systems in industrial countries on milk production, udder health, reproduction and behaviour of high-producing dairy cows, and the effects on the gain, health and behaviour of the calves. The suckling systems are divided into three...

  9. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  10. Effects of grouping piglets and changing sow location on suckling behaviour and performance

    Contributor(s):: Wattanakul, W., Stewart, A. H., Edwards, S. A., English, P. R.

    36 sows and litters were used to study how suckling behaviour was influenced by grouping of piglets and changing sow location under controlled conditions. Control sows (C) remained in farrowing pens with crates until weaning at 28 days. In treatment 1 (T1), piglets from 3 litters were grouped in...

  11. Experience of moderate bedding affects behaviour of growing pigs

    Contributor(s):: Munsterhjelm, C., Peltoniemi, O. A. T., Heinonen, M., Halli, O., Karhapaa, M., Valros, A.

    Effects of early substrate-enrichment on behaviour and productivity of pigs were evaluated in a trial with four siblings as the experimental unit. Pens either were (=E) or were not (=0) moderately bedded with wood shavings and chopped straw during suckling (0-4 weeks of age), nursery (5-9 weeks)...

  12. Individual differences in behaviour and in adrenocortical activity in beef-suckler cows

    Contributor(s):: Mulleder, C., Palme, R., Menke, C., Waiblinger, S.

    The aims of this study were to investigate the existence of individual behavioural strategies in beef-suckler cows in a stable herd, whether these strategies are related to basic activities and to adrenocortical activity, and whether they are consistent in a situation of social competition....

  13. Individual differences in responses of piglets to weaning at different ages

    Contributor(s):: Mason, S. P., Jarvis, S., Lawrence, A. B.

    Several studies indicate each piglet within a litter is affected differently by weaning and that these individual responses may be altered by the age of the litter at weaning. In the present study, eight litters of individually marked piglets (n=79) were randomly assigned to be weaned at 21 or 35...

  14. Intersucking in dairy cattle - review and questionnaire. (Special Issue: Behaviour and welfare of cattle)

    Contributor(s):: Lidfors, L., Isberg, L.

    Intersucking is an abnormal behaviour in dairy heifers and cows, and it is defined by one animal sucking the teat of another animal with the intention of sucking milk. The aim of this paper is to review earlier studies on intersucking in dairy cattle and to present results from a questionnaire...

  15. Lithium residue in milk from doses used to condition taste aversions and effects on nursing calves

    Contributor(s):: Ralphs, M. H.

    In the 1st trial, 3 lactating Hereford cows with calves 4-7 months of age were gavaged with lithium chloride at 100, 150 and 200 mg/kg liveweight. Milk yield and lithium concentration in blood serum and milk were measured at intervals up to 96 h after treatment. Milk yield decreased by 20% the...

  16. Mother-young relationships in Belgian Blue cattle after a Caesarean section: characterisation and effects of parity. (Special issue: Suckling)

    Contributor(s):: Vandenheede, M., Nicks, B., Desiron, A., Canart, B.

    The systematic use of Caesarean section in "double muscled" Belgian Blue cattle can induce ethical concerns. The aims of the following study was to characterise mother-young relationships in such a situation and to assess the effect of parity. Fifteen heifers and 15 cows of the Belgian Blue breed...

  17. Motivational and physiological analysis of the causes and consequences of non-nutritive sucking by calves

    Contributor(s):: Passille, A. M. de, Rushen, J.

    Non-nutritive sucking by calves of an artificial, dry teat was examined. Most non-nutritive sucking occurred directly after a meal and was elicited by the taste of milk. Increasing the volume of milk drunk did not reduce the amount of non-nutritive sucking, suggesting that the consumption of milk...

  18. Naloxone cannot abolish the lack of oxytocin release during unexperienced suckling of dairy cows. (Special issue: Suckling)

    Contributor(s):: Kraetzl, W. D., Tancin, V., Schams, D., Bruckmaier, R. M.

    To evaluate the role of opioids for the regulation of oxytocin release in response to teat stimulation, 10 brown-Swiss dairy cows in mid-lactation were randomized to two experiments. In the first experiment, four cows without previous suckling experience were suckled by an alien calf between two...

  19. Nursing behaviour of sows during 5 weeks lactation and effects on piglet growth

    Contributor(s):: Valros, A. E., Rundgren, M., Spinka, M., Saloniemi, H., Rydhmer, L., Algers, B.

    The main goal of this study was to investigate the effect of sow nursing behaviour on piglet liveweight gain and within-litter variation (WLV) in piglet liveweight gain under as naturalistic conditions as possible. In order to achieve this, patterns of sow nursing behaviour and piglet liveweight...

  20. Oxytocin facilitates behavioural, metabolic and physiological adaptations during lactation. (Special issue: Suckling)

    Contributor(s):: Uvnas-Moberg, K., Johansson, B., Lupoli, B., Svennersten-Sjaunja, K.

    This article aims to propose that oxytocin not only stimulates milk letdown, but also adapts behaviour and physiology to facilitate lactation in mammals, including dairy cattle. Circulating oxytocin as well as neurogenic oxytocin participates in these regulatory processes. In short, oxytocin...
