| Contributor(s):: Oliveira, D. de, Barth, K., Haskell, M. J., Hillmann, E., Jensen, M. B., Johnsen, J. F., Mejdell, C., Waiblinger, S., Ferneborg, S.
In this Research Reflection we describe a common standpoint on suitable methodology for controlled and observational studies in cow-calf contact systems in dairy production. Different methods to assess behaviour, health and production in cow-calf contact systems are outlined. Knowledge and...

A Survey of Italian Dairy Farmers' Propensity for Precision Livestock Farming Tools
| Contributor(s):: Fabio Abeni, Francesca Petrera, Andrea Galli
A targeted survey was designed with the aim of describing the diffusion of precision livestock farming (PLF) tools in one of the most intensive dairy farming provinces in Italy. Technicians at the Provincial Breeder Association of Cremona interviewed 490 dairy farmers and obtained data...
Human-Animal Relationship in Dairy Farming: Evaluation of measures for on-farm application and investigation of influences on cows´ behaviour towards humans
| Contributor(s):: Asja Ebinghaus
The objective of the present thesis was (1) to evaluate measures of the human-animal relationship (HAR) in dairy cows regarding their reliability, validity and practical applicability in animal welfare science and breeding. (2) Moreover, important human and farm influences on the cows´...

Effects of access to hay on cognition of pre-weaned dairy calves and behavior upon social grouping after weaning
| Contributor(s):: Horvath, Kelsey C., Gingerich, Katie N., Hixson, Catherine L., Miller-Cushon, Emily K.
Individually housed dairy calves typically have restrictive environments which could lead to detrimental effects on cognition. We hypothesized that providing calves with hay prior to weaning, in addition to a standard starter diet and milk, would improve cognitive ability and influence adaptation...
Aplicabilidad del protocolo Welfare Quality® para medir bienestar animal en crianzas de sistemas de producción de bovinos de leche nacionales
| Contributor(s):: Claudia Andrea Bottaro Morosetti
En este trabajo se estudia la aplicabilidad en Chile, del protocolo diseñado por el proyecto Welfare Quality ® para evaluar el bienestar animal en crianzas de bovinos de leche. Para esto, se aplicaron en 13 lecherías del país, cuatro pruebas directas (Distancia de Fuga...
Which measures of acceleration best estimate the duration of locomotor play by dairy calves?
| Contributor(s):: Luu, John, Johnsen, Julie Føske, Passillé, Anne Marie de, Rushen, Jeffrey
Measures of acceleration have been used as automated measures of the locomotor play of calves. We examined which measures of acceleration were best correlated with locomotor play and how the sampling rate of the accelerometer affected the correlations. Accelerometers were attached to 30 6–7...
Suckling, weaning, and the development of oral behaviours in dairy calves
| Contributor(s):: Veissier, Isabelle, Caré, Sara, Pomiès, Dominique
Dairy calves are generally separated from their dam at birth. They express non-nutritive oral activities such as licking or sucking other calves or objects, nibbling, or tongue-playing, which have been related to the absence of sucking a teat and ingestive chewing. We hypothesized that the dam,...
Play behavior as an indicator of animal welfare: Disbudding in dairy calves
| Contributor(s):: Mintline, Erin M., Stewart, Mairi, Rogers, Andrea R., Cox, Neil R., Verkerk, Gwyneth A., Stookey, Joseph M., Webster, James R., Tucker, Cassandra B.
Play behavior may be reduced during negative experiences (e.g. pain) and serve as an indicator of animal welfare. To test this, the effects of a non-steroidal anti-inflammatory drug (NSAID) and a local anesthetic (LA) on dairy calf play behavior and wound sensitivity of calves after hot-iron...
Dairy calves’ adaptation to group housing with automated feeders
| Contributor(s):: Fujiwara, Mayumi, Rushen, Jeffrey, de Passillé, Anne Marie
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...
The level of social contact affects social behaviour in pre-weaned dairy calves
| Contributor(s):: Duve, Linda Rosager, Jensen, Margit Bak
The present study investigated the effects of the level of social contact in the home environment on the social preference, bonding and social behaviour of pre-weaned dairy calves. Twenty-seven pairs of calves were reared from birth until 6 weeks either individually (with limited social contact...
Cross-sucking by dairy calves may become a habit or reflect characteristics of individual calves more than milk allowance or weaning
| Contributor(s):: de Passillé, Anne Marie, Borderas, Fernando, Rushen, Jeffrey
To examine the effects of milk allowance and weaning age on cross-sucking, 45 dairy calves were housed in groups of nine and fed milk and grain-based starter feed from automated feeders and allocated to three treatment groups: (A) Low-Milk Early-Weaned (fed 6L/d of milk until weaned at 47 d of...
Automated measurement of acceleration can detect effects of age, dehorning and weaning on locomotor play of calves
| Contributor(s):: Rushen, Jeffrey, de Passillé, Anne Marie
Play may be a behavioural indicator of positive emotions in young animals, but in calves spontaneous play is time consuming to record. We examined whether measures of acceleration of calves in a large enclosure could detect effects on play running of age, dehorning and weaning off milk. Holstein...

Contact with cows during the young age increases social competence and lowers the cardiac stress reaction in dairy calves
| Contributor(s):: Buchli, Cornelia, Raselli, Alice, Bruckmaier, Rupert, Hillmann, Edna
Separating calf and cow within 24h after birth is common practice in dairy farms. Some dairy farmers, however, practice a rearing system in which the calves are nursed by their dam or by foster cows. We investigated if dairy calves reared in such a system (calves with cow-contact) differ in their...
The effect of feeding enrichment in the milk-feeding stage on the cognition of dairy calves in a T-maze
| Contributor(s):: Horvath, Kelsey, Fernandez, Mariana, Miller-Cushon, Emily K.
In many species, environmental complexity is known to affect cognitive development, yet it is common to house dairy calves individually in restrictive environments. The hypothesis of this study was that providing calves with simple nutritional enrichments would improve their success in a...
Is rearing calves with the dam a feasible option for dairy farms?—Current and future research
| Contributor(s):: Johnsen, Julie Føske, Zipp, Katharina A., Kälber, Tasja, Passillé, Anne Marie de, Knierim, Ute, Barth, Kerstin, Mejdell, Cecilie Marie
In the dairy industry it is common practice to separate cow and calf shortly after birth but this practice is disputed because of animal welfare concerns. Some producers, in many countries, milk cows that also nurse dairy calves. These cow–calf systems allow nursing as well as affiliative and...
