Tempo and Mode of Domestication During the Neolithic Revolution: Evidence from Dental Mesowear and Microwear of Sheep
| Contributor(s):: Melissa Zolnierz
The Neolithic Revolution marked a dramatic change in human subsistence practices. In order to explain this change, we must understand the motive forces behind it. Researchers have proposed many different stimuli, with most theories invoking environmental dynamics, human population density...
Identification of QTLs for behavioral reactivity to social separation and humans in sheep using the OvineSNP50 BeadChip
| Contributor(s):: Dominique Hazard, Carole Moreno, Didier Foulquié, Eric Delval, Dominique François, Jacques Bouix, Guillaume Sallé, Alain Boissy
Background Current trends in sheep farming practices rely on animals with a greater level of behavioral autonomy than before, a phenotype that actively contributes to the sustainability of animal production. Social reactivity and reactivity to humans are relevant behavioral traits in sheep,...
Perception of animal sentience by Brazilian and French citizens: The case of sheep welfare and sentience

Addressing the Challenges of Conducting Observational Studies in Sheep Abattoirs
| Contributor(s):: Elyssa Payne, Melissa Starling, Paul McGreevy
The competing needs of maintaining productivity within abattoirs, and maintaining high standards of animal welfare, provide fertile grounds for applied research in animal behavior. However, there are challenges involved in capturing useful behavioral data from the supply chain (from paddock to...
Pregnant Sheep in a Farm Environment Did Not Develop Anaemia
| Contributor(s):: Gabrielle C. Musk, Amanda James, Matthew W. Kemp, Sara Ritchie, Andrew Ritchie, Michael Laurence
The aim of this study was to document the haematological profile of pregnant ewes throughout gestation. Sheep were divided into three groups (n = 8 per group): non-pregnant, singleton, or twin pregnancy. Blood samples were collected every 14 days from day 55 of gestation for haemoglobin...
Understanding Life Skills Gained from and Reasons for Youth Participation in the Tennessee 4-H Sheep Skillathon
| Contributor(s):: Terra Kimes Davis, Christopher T. Stripling, Carrie A. Stephens, H. Dwight Loveday
The high number of U.S. youth exhibiting at-risk behavior points to a lack of life skills development. We determined the effects of participating in one state's 4-H sheep skillathon on youths' life skills development and the youths' reasons for participating. The target population was...
Revealing the History of Sheep Domestication Using Retrovirus Integrations
| Contributor(s):: Bernardo Chessa, Filipe Pereira, Frederick Arnaud, Antonio Amorim, Felix Goyache, Ingrid Mainland
The domestication of livestock represented a crucial step in human history. By using endogenous retroviruses as genetic markers, we found that sheep differentiated on the basis of their "retrotype" and morphological traits dispersed across Eurasia and Africa via separate migratory...
Sheep farmer opinions on the current and future role of veterinarians in flock health management on sheep farms: a qualitative study
| Contributor(s):: Jasmeet Kaler, L.E. Green
A 2009 UK Government report on veterinary expertise in food animal production highlighted that there was insufficient herd health expertise among veterinarians and lack of appropriate business models to deliver veterinary services to the livestock sector. Approximately two thirds of sheep farmers...
Introducing Livestock-Guarding Dogs
| Contributor(s):: Jay R. Lorenz
Livestock-guarding dogs are one of a variety of tools that sheep and goat producers are finding effective for preventing livestock losses to predators. Guarding dogs are used alone or in combination with other controls to keep predators out of flocks and herds.
Farmer and public attitudes toward lamb finishing systems
| Contributor(s):: Coleman, G., Jongman, E., Greenfield, L., Hemsworth, P.
To develop research and policy on the welfare of lambs in intensive finishing systems, it is important to understand public and sheep farmers' attitudes. The aim of this research was to identify and compare farmer and community attitudes relevant to the intensification of lamb finishing. The...
On-farm qualitative behaviour assessment in sheep: repeated measurements across time, and association with physical indicators of flock health and welfare
| Contributor(s):: Phythian, C. J., Michalopoulou, E., Cripps, P. J., Duncan, J. S., Wemelsfelder, F.
Qualitative Behavioural Assessment (QBA) is a 'whole-animal' methodology that assesses the expressive qualities of animal behaviour using terms such as 'tense', 'relaxed', 'anxious', and 'content'. The reliability and validity of QBA as an indicator for on-farm welfare assessment in pigs, cattle,...
Training rams to court and mate female goats
| Contributor(s):: Orihuela, A., Ungerfeld, R.
As Saint-Croix rams (sheep) exhibit low seasonal reproductive changes, they could be effective in inducing a reproductive response during the non-breeding season in anestrous does (goats) of breeds whose bucks show low reproductive activity. Three management practices for training rams to court...
Development of a facial expression scale using footrot and mastitis as models of pain in sheep
| Contributor(s):: McLennan, K. M., Rebelo, C. J. B., Corke, M. J., Holmes, M. A., Leach, M. C., Constantino-Casas, F.
Management of pain in sheep is limited by the challenges of recognising and accurately quantifying pain in this species. The use of facial expression scoring to assess pain is a well-utilised, practical tool in both humans and non-human animals. The objective of this study was to develop a...
Manifestation of neuronal ceroid lipofuscinosis in Australian Merino sheep: observations on altered behaviour and growth
| Contributor(s):: Cronin, G. M., Beganovic, D. F., Sutton, A. L., Palmer, D. J., Thomson, P. C., Tammen, I.
Neuronal ceroid lipofuscinoses (NCL) is an inherited neurodegenerative disorder in children. Presently there is no effective treatment and the disorder is lethal. NCL occur in a variety of non-human species including sheep, which are recognised as valuable large animal models for NCL. This...
