Managing large litters: Selected measures of performance in 10 intermediate nurse sows and welfare of foster piglets
Contributor(s):: Kobek-Kjeldager, Cecilie, Moustsen, Vivi A., Theil, Peter K., Pedersen, Lene J.
Selection for increased litter size has led to the use of so-called nurse sows in several European countries. A nurse sow receives new piglets after having weaned her own. Nurse sows are often made in two-steps. In the two-step strategy, new-born piglets are given to a sow 4–7 days into...
Effect of litter size, milk replacer and housing on behaviour and welfare related to sibling competition in litters from hyper-prolific sows
Litter sizes where piglets are supernumerary to teats leads to the practice of fostering to nurse sows or to artificial rearing systems, which is associated with compromised welfare. An alternative strategy is to leave the supernumerary piglets with their own dam and provide milk replacer in the...
Group suckling cohesion as a prelude to the formation of teat order in piglets
Contributor(s):: Skok, Janko, Škorjanc, Dejan
During the lactation period, piglets experience intense social interactions with their littermates until they establish a reliable teat order on the mother's udder. Here, we examined group suckling cohesion in piglet littermates, an order mechanism that refer to the maintenance of significantly...
Formation of teat order and estimation of piglets’ distribution along the mammary complex using mid-domain effect (MDE) model
Domestic piglets (Sus scrofa domesticus) establish relatively stable teat order after the first week postpartum. Formation of teat order is normally accompanied by intense competition between littermates. In this period, piglets’ behaviour and their distribution along the mammary complex is...
Behavioural patterns established during suckling reappear when piglets are forced to form a new dominance hierarchy
Contributor(s):: Skok, Janko, Prevolnik, Maja, Urek, Tina, Mesarec, Nikolina, Škorjanc, Dejan
Early life experiences considerably influence the behavioural development of the animals in which the social environment plays a crucial role. Neonatal piglets experience intense social (including aggressive) interactions when compete with their littermates for the access to teats on the sow's...
Neonatal piglets are able to differentiate more productive from less productive teats
Contributor(s):: Devillers, Nicolas, Giraud, Delphine, Farmer, Chantal
A previously-validated method to induce variation in milk production between teats of the same udder that is not related to the ante-posterior location of the teat was used. In the first lactation, over half of the sows' teats (teats 1, 2, 5, 6, and 7 from 1 side of the udder, and teats 3, 4,...
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...
Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality
Contributor(s):: Muns, R., Manteca, X., Gasa, J.
An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...
Influences of various factors on cows' entrance order into the milking parlour
Contributor(s):: Polikarpus, A., Kaart, T., Mootse, H., Rosa, G. de, Arney, D.
This study investigates the stability of the milking order of cows entering into the milking parlour of a commercial dairy herd, and changes to this order consequent to a change in health status and a change in the membership of the group of cows being milked. In large herds it is difficult for...
Effectiveness of animal health and welfare planning in dairy herds: a review
Contributor(s):: Tremetsberger, L., Winckler, C.
Maintaining and promoting animal health and welfare are important but challenging goals in livestock farming. Animal health and welfare planning aims to contribute to improvements in the herd through interventions in a structured way. This review provides an overview of current scientific...
Supernumerary teat removal can be avoided in dairy sheep
Contributor(s):: Palacios, C., Abecia, J. A.
The aim of this work was to determine whether the removal of supernumerary teats from dairy sheep when they are born is a useful procedure in the farming routine. Ewes were divided into 3 groups according to the number of teats at milking: ewes who were born with 2 teats; ewes who were born with...
Dairy calves' adaptation to group housing with automated feeders
Contributor(s):: Fujiwara, M., Rushen, J., Passille, A. M. de
Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

Stepping and kicking behaviour during milking in relation to response in human-animal interaction test and clinical health in loose housed dairy cows
Contributor(s):: Rousing, T., Bonde, M., Badsberg, J. H., Sorensen, J. T.
Associations between kicking and stepping behaviour during milking and response to humans, getting up behaviour as well as clinical health status in loose housed dairy cows were investigated. During a 12-month period behavioural and clinical data from 10 commercial Danish dairy herds were...
Behaviour, synchrony and welfare of Pekin ducks in relation to water use
Contributor(s):: Waitt, C., Jones, T., Dawkins, M. S.
The method of providing bathing water to commercially farmed ducks presents potential logistic, welfare and health issues. Welfare may be compromised if ducks do not have access to water in which they can at least dip their heads and spread water over their feathers. However maintaining hygiene...
Form but not frequency of beak use by hens is changed by housing system
Contributor(s):: Shimmura, T., Suzuki, T., Azuma, T., Hirahara, S., Eguchi, Y., Uetake, K., Tanaka, T.
In order to verify the hypothesis that hens in different housing systems have the same time budget for different beak-related behaviours, we compared the pecking behaviour of hens in six housing systems: small (SC) and large (LC) conventional cages, small (SF) and large (LF) furnished cages,...
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...
