The sucking behaviour and milk intake of one- to three-week-old triplet lambs during natural and competitive suckling situations
Contributor(s):: Van Welie, L. A., Clews, S. A., Beausoleil, N. J., Hickson, R., Kongara, K., Kenyon, P. R., Morris, S. T.
Within triplet litters, light-born lambs are at greater risk of dying than heavier lambs in the first week of life. However, the implications of within-litter differences in sucking behaviour for milk intake and growth beyond the first week are unclear. We hypothesized that within litter,...
Preference for the mother does not last long after weaning at 3 months of age in sheep
Contributor(s):: Ungerfeld, Rodolfo, Freitas-de-Melo, Aline, Nowak, Raymond, Lévy, Frederic
Ewes develop a strong selective bond with their offspring, which is set immediately after lambing and maintained until weaning, which in domestic sheep occurs when lambs are 4-5 months old. However, in productive systems lambs are weaned earlier, when they are 2-5 months old. The aim of this...
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...
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...
Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy
Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.
This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...
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...
Space allowance during gestation and early maternal separation: effects on the fear response and social motivation of lambs
Contributor(s):: Averos, X., Marchewka, J., Beltran de Heredia, I., Zanella, A. J., Ruiz, R., Estevez, I.
A common prenatal stressor in lambs is early maternal separation, which may be aggravated by spatial restriction of ewes during pregnancy. They may influence lambs' development and coping abilities. The aim of this study was to determine how space allowance provided to ewes during pregnancy and...
Behavior of lambs in rest pens during long-distance transport
Contributor(s):: Krawczel, P. D., Friend, T. H., Archer, G. S.
The aim of this study was to determine how one group of lambs utilized 2 consecutive rest periods in novel environments with access to food and water that occurred during 22 hr of motor transport. The 18.5+or-0.6 kg lambs (n=15) were transported for 8 hr and then unloaded for a 6-hr rest period....
Effect of postweaning handling strategies on welfare and productive traits in lambs
Contributor(s):: Pascual-Alonso, M., Miranda-de Lama, G. C. la, Aguayo-Ulloa, L., Ezquerro, L., Villarroel, M., Marin, R. H., Maria, G. A.
Postweaning management strategies that include an element of social enrichment may reduce weaning stress and improve welfare and productive performance. We analyzed the effect of postweaning handling strategies on welfare and production traits in lambs. After weaning, 36 lambs were assigned to 3...
A comparison of handling methods relevant to the religious slaughter of sheep
Contributor(s):: Bates, L. S. W., Ford, E. A., Brown, S. N., Richards, G. J., Hadley, P. J., Wotton, S. B., Knowles, T. G.
Legislation governing non-stun slaughter of sheep in England requires that they are individually and mechanically restrained for slaughter and not moved for at least 20 s post neck cut, until unconsciousness or insensibility occurs. Complying with the need for individual handling, in what is a...
Attitudes of Nebraska sheep producers toward predators
Contributor(s):: Dale J. Hafer, Scott E. Hygnstrom
The economy of the State of Nebraska is highly dependent on the agricultural industry. When factors arise that complicate and threaten facets of the industry, those involved, particularly producers, often express a high degree of concern toward those threatening factors.The sheep producers of...

Contributor(s):: Caroprese, M., Napolitano, F., Boivin, X., Albenzio, M., Annicchiarico, G., Sevi, A.
The interactions between genetic and environmental factors on the development of lamb affinity to humans was assessed on 48 animals from two breeds (Gentile di Puglia and Comisana) and two treatments (Gentled and Not Gentled) producing 4 groups (GPg, GPng, Cg, Cng, respectively). The Gentile di...
Effects of early maternal separation of lambs and rearing with minimal and maximal human contact on meat quality
Contributor(s):: Napolitano, F., Caroprese, M., Girolami, A., Marino, R., Muscio, A., Sevi, A.
The present study aims to assess the effect of gentling on behaviour and meat quality of lambs. Thirty-two Comisana lambs were divided into four groups of eight animals: ER (ewe reared), AR (artificially reared) and the corresponding gentled groups ERG and ARG. The provision of human contacts...
