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...

Producer Perceptions of Food-Borne and Zoonotic Diseases: Sheep and Goats
Contributor(s):: Paula Menzies
Work with the community and producers to understand perceptions of food-borne and zoonotic disease issues in the industry. Use this research to develop preferred knowledge translation methods to address needs and concerns.
Reactions of sheep towards three sets of emotional stimuli: (in) consistency in respect to stimulus valence and sheep identity
Contributor(s):: Gygax, L., Vogeli, S.
There is an increasing interest in affective states in applied animal behaviour science, because these states are thought to reflect welfare from the perspective of the animals. Also, it can be expected that individuals differ in how they consistently react to emotional challenges. Recently, we...
Etre un ovin malade en Bas-Berry (fin XVIII e - milieu XX e siecle)
Contributor(s):: Baron, N.
The purpose of this article is to make use of the "animal viewpoint", which has been adopted by a growing number of researchers, to reconstruct the experience of Indre sheep affected by the disease from the late eighteenth to the mid-twentieth centuries. To this end, we rely on local archives and...
Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs
Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.
The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...
Animal exploitation during the Old Kingdom in Egypt: contribution from Ayn Asil (Dakhla Oasis)Exploitation animale a l'Ancien Empire en Egypte: les apports d'Ayn Asil (oasis de Dakhla)
Contributor(s):: Lesur, J.
At the end of the Old Kingdom in Egypt, food production relies on a dense agriculture in the Delta and the Nile valley as well as on livestock herding and fishing. The situation is however different in the Western Desert which undergoes a strong aridification. Archaeozoological remains coming...

A pilot study to develop an assessment tool for sheep welfare after long journey transport
Contributor(s):: Messori, S., Sossidou, E., Buonanno, M., Mounaix, B., Barnard, S., Vousdouka, V., Villa, P. dalla, Roest, K. de, Spoolder, H.
Sheep transport within Europe involves 9.5 million animals yearly, 63% of which travel over long journeys (>8 h). Livestock transport, particularly over long journeys, gives rise to concern about the welfare of transported animals. The European Commission stimulates the development of...
Validating the use of qualitative behavioral assessment as a measure of the welfare of sheep during transport
Contributor(s):: Wickham, S. L., Collins, T., Barnes, A. L., Miller, D. W., Beatty, D. T., Stockman, C. A., Blache, D., Wemelsfelder, F., Fleming, P. A.
We tested the application of qualitative behavioral assessment (QBA) as a welfare assessment tool. Sheep were exposed to road transport treatments, and behavioral expressions were compared between experimental treatments and validated by correlation with physiological measures. We compared...

Contributor(s):: Schilling, A. K., Reese, S., Palme, R., Erhard, M., Wohr, A. C.
Sheep and goats are frequently used in nonhuman animal-assisted activities on city farms. There are few data available on this type of usage of small ruminants. Health evaluations, behavioral observations (feeding, resting, comfort, explorative and social behaviors), behavioral tests (human...
New insights into the Early Neolithic economy and management of animals in Southern and Central Europe revealed using lipid residue analyses of pottery vessels
Contributor(s):: Salque, M., Radi, G., Tagliacozzo, A., Uria, B. P., Wolfram, S., Hohle, I., Stauble, H., Whittle, A., Hofmann, D., Pechtl, J., Schade-Lindig, S., Eisenhauer, U., Evershed, R. P.
Analyses of organic residues preserved in ceramic potsherds enable the identification of foodstuffs processed in archaeological vessels. Differences in the isotopic composition of fatty acids allow differentiation of non-ruminant and ruminant fats, as well as adipose and dairy fats. This paper...
Behavioural reactivity of ewes and lambs during partial and total social isolation
Contributor(s):: Barnard, S., Matthews, L. R., Messori, S., Vulpiani, M. P., Ferri, N.
This work investigated the differences in the reactivity of Sarda (primiparous n=18, multiparous n=17) and Dorset (multiparous n=8) breeds of sheep and their singleton lambs to two challenging test situations involving a mother-lamb partial separation test and an isolation test. Non-parametric...
Filial attachment in sheep: similarities and differences between ewe-lamb and human-lamb relationships
Contributor(s):: Nowak, R., Boivin, X.
Animals develop relationships with intra- and interspecific partners, including humans. In some cases this can lead to strong emotional bonds indicating the existence of attachment. The sheep is well known to develop various forms of social attachment (mothers towards young, lambs towards...
