Breed-related differences in the preference for inanimate objects between chicks of laying hens
Contributor(s):: Kasperek, Kornel, Zięba, Grzegorz, Pluta, Adrian, Ziemiańska, Agnieszka, Rozempolska-Rucińska, Iwona
Our previous study showed significant behavioural differences between breeds of laying hens. Birds differed in their excitability, reactivity, decision-making speed, behavioural strategy, and interest in elements of the surroundings. The results of our investigations and studies conducted by...
The effects of a choice test between food rewards and human interaction in a herd of domestic horses of varying breeds and experiences
Contributor(s):: Kieson, Emily, Felix, Crystal, Webb, Summer, Abramson, Charles I.
Humans use food rewards as positive reinforcement for training horses, but there is little evidence to show that human interaction (scratching or patting) has reward value or if domestic horses perceive human touch as social bonding. Most equine training is based on negative reinforcement, but...
Cow in Motion: A review of the impact of housing systems on movement opportunity of dairy cows and implications on locomotor activity
Contributor(s):: Shepley, Elise, Lensink, Joop, Vasseur, Elsa
As humans, we recognize the importance of exercise. We go to the gym, walk our dogs, and ride our horses. Even our hamsters get a wheel to run on. Considering this, it is surprising that, when it comes to the production animals that make up the bulk of domestic animals, the concept of ‘exercise’...
Range use is related to free-range broiler chickens’ behavioral responses during food and social conditioned place preference tests
Contributor(s):: Ferreira, Vitor Hugo Bessa, Germain, Karine, Calandreau, Ludovic, Guesdon, Vanessa
Free-range broiler chickens usually show an uneven spatial utilization of an outdoor range. Due to behavioral and cognitive between-individual differences, some animals may be driven to associate food and conspecifics more strongly to the barn, causing them to be less prone to explore the range....
What Makes a Rabbit Cute? Preference for Rabbit Faces Differs according to Skull Morphology and Demographic Factors
| Contributor(s):: Naomi D. Harvey, James A. Oxley, Giuliana Miguel-Pacheco, Emma M. Gosling, Mark Farnworth
Domesticated rabbits typically exhibit shorter, flatter skulls than their wild counterparts (brachycephalism). However, brachycephaly is associated with considerable health problems, including problems with dentition. The aim of this study was to establish which type of rabbit face people...
US Residents’ Perceptions of Dog Welfare Needs and Canine Welfare Information Sources
| Contributor(s):: Bir, Courtney, Croney, Candace C., Widmar, Nicole J. Olynk
The extent to which welfare needs of breeding dogs are met in commercial dog-breeding kennels is a potential point of controversy. This analysis sought to understand US residents’ perceptions and priorities related to dog welfare : by investigating (a) perceptions of breeding-dog welfare needs...
Individuality matters for substrate-size preference in the Nile tilapia juveniles
| Contributor(s):: Maia, Caroline Marques, Volpato, Gilson Luiz
Preference tests have usually been used to identify nonhuman animal preferences for welfare purposes (environmental enrichment), but they are mostly at the group level—that is, group preferences for resources or environmental conditions. However, a more robust method was developed to analyze...
Evaluating the social structure of captive Rothschild’s giraffes (Giraffa camelopardalis rothschildi): Relevance to animal management and animal welfare
| Contributor(s):: Lewton, Jack, Rose, Paul E.
Social network analysis (SNA) is useful for evaluating management zoo regimes to ensure that any fitness benefits of sociality are preserved in captive-housed groups. This paper explores the association patterns of 13 giraffes housed at Longleat Safari Park, UK. Wild giraffes exhibit a...
Designing Better Water Troughs: Does Trough Color Influence Dairy Cows’ Preference?
| Contributor(s):: Teixeira, Dayane Lemos, Hötzel, Maria José, Filho, Luiz Carlos Pinheiro Machado, Cazale, José Daniel, Enríquez-Hidalgo, Daniel
Eighteen lactating dairy cows were used to elucidate their preference for green, grey, or red troughs. The herd was managed under a rotational grazing system with ad-libitum access to water until 11:30 h. For 9 days, all cows were tested individually following the afternoon milking. Cows drank...
Seeing Dogs: Human Preferences for Dog Physical Attributes
| Contributor(s):: Hecht, Julie, Horowitz, Alexandra
This study systematically investigated peoples' preferences for dog physical attributes in images of real-life dogs. Participants (n = 124) completed an aesthetic-preference test wherein they viewed 80 image pairs of mixed-breed adult dogs and were asked which image they “liked best.” In each...
Preference of beef cattle for feedlot or pasture environments
| Contributor(s):: Lee, Caroline, Fisher, Andrew D., Colditz, Ian G., Lea, Jim M., Ferguson, Drewe M.
Intensive feedlot finishing is perceived to affect welfare because cattle cannot perform normal behaviours evident in pasture environments. The objective of this study was to determine cattle preference for spending time at pasture (5ha) or in a feedlot (25×10m) under pastures with differing feed...
The preference of 0+ and 2+ gilthead seabream Sparus aurata for coloured substrates or no-substrate
| Contributor(s):: Batzina, Alkisti, Sotirakoglou, Kyriaki, Karakatsouli, Nafsika
A major component of animal welfare is to provide for the behavioural and psychological needs of captive animals. A means to estimate these needs is preference tests. However, what an animal chooses may not prove to be beneficial for its long-term health and welfare. The long-term effect (for...
Positive affective state induced by opioid analgesia in laying hens with bone fractures
| Contributor(s):: Nasr, M. A. F., Browne, W. J., Caplen, G., Hothersall, B., Murrell, J. C., Nicol, C. J.
Laying hens with keel fractures (n=35) and control hens with no fractures (n=12) were trained to associate the colour and position of an environment with the effects of either a subcutaneous injection of an opioid analgesic drug (butorphanol) or a subcutaneous injection of saline in a conditioned...
Methods for cross point analysis of double-demand functions in assessing animal preferences
| Contributor(s):: Engel, Bas, Webb, Laura E., Jensen, Margit Bak, van Reenen, Cornelis G., Bokkers, Eddie A. M.
Cross point analysis of double demand functions provides a compelling way to quantify the strength of animal preferences for two simultaneously presented resources. During daily sessions, animals have to work to gain access to (a portion of) either resource, e.g. by pressing one of two panels a...
Does the presence of a human affect the preference of enrichment items in young, isolated pigs?
| Contributor(s):: DeBoer, Shelly P., Garner, Joseph P., Lay, Donald C., Eicher, Susan D., Lucas, Jeffrey R., Marchant-Forde, Jeremy N.
Pigs may be housed individually in both production and research settings. Gregarious by nature, pigs kept in isolation may show behavioural and physiological signs of stress. In this study we investigated the preference of individually housed pigs, for social and non-social enrichments. Three...
Does nest size matter to laying hens?
| Contributor(s):: Ringgenberg, Nadine, Fröhlich, Ernst K. F., Harlander-Matauschek, Alexandra, Würbel, Hanno, Roth, Beatrice A.
Laying hens in loose housing systems have access to group-nests which provide space for several hens at a time to lay their eggs. They are thus rather large and the trend in the industry is to further increase the size of these nests. Though practicality is important for the producer, group-nests...
Do hens have friends?
| Contributor(s):: Abeyesinghe, Siobhan M., Drewe, Julian A., Asher, Lucy, Wathes, Christopher M., Collins, Lisa M.
Recent interest in positive welfare has encouraged consideration of the formation of socio-positive relationships in farmed species which may provide a means by which to manage positive states. We investigated in detail the existence of dyadic preferential associations in small groups of domestic...
