  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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.

  7. 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...

  8. 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,...

  9. 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...

  10. 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...

  11. 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...

  12. Quantitative assessment of bullet fragments in viscera of sheep carcasses as surrogates for white-tailed deer

    Contributor(s):: Cruz-Martinez, Luis, Grund, Marrett D., Redig, Patrick T.

  13. Jaguar and puma attacks on livestock in Costa Rica

    Contributor(s):: Amit, Ronit, Gordillo-Chavez, Elias Jose, Bone, Raquel

  14. Bullet fragmentation and lead deposition in white-tailed deer and domestic sheep

    Contributor(s):: Grund, M. D., Cornicelli, L., Carlson, L. T., Butler, E. A.

  15. 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.

  16. 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...

  17. 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...

  18. 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...

  19. 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...
