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...
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....
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...
Assessment of unconsciousness during slaughter without stunning in lambs

Development of affinity to the stockperson in lambs from two breeds
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...
New Zealand farmer narratives of the benefits of reduced human intervention during lambing in extensive farming systems
Contributor(s):: Fisher, M.
Easy-care or natural lambing pertains to those sheep able to successfully lamb and rear at least one lamb without human assistance in a difficult environment. Such sheep may have a higher survival rate, lower lamb mortality, and require less shepherding at lambing than other sheep breeds or...
Temporal association between food distribution and human caregiver presence and the development of affinity to humans in lambs
Contributor(s):: Tallet, C., Veissier, I., Boivin, X.
The presence of the caregiver around feeding favors the development of a human-animal relationship. To understand the underlying mechanism, we tested various temporal associations between food distribution and human presence: from an early age, a person was repeatedly present for 2 min just...
A note on behavioural laterality in neonatal lambs
Contributor(s):: Lane, A., Phillips, C.
In some mammals behavioural laterality is influenced by the perinatal environment, through stress effects on brain lateralisation, and by gender through variation in testosterone secretion. Therefore, a study was conducted on 54 neonatal lambs to determine whether laterality existed at birth and...
A note on sheltering behaviour by ewes before and after lambing
Contributor(s):: Pollard, J. C., Shaw, K. J., Littlejohn, R. P.
The effects of lambing and lamb rearing on sheltering behaviour was investigated in multiparous Romney x Perendale crossbred ewes with either 9 (5 ewes) or 3 months (5) of wool growth during daylight hours for 6 weeks over the lambing period, in a pasture with little vegetative shelter but with a...
A note on the use of odor manipulation to facilitate the adoption of alien lambs by ewes bearing twins
Contributor(s):: Price, E. O., Dally, M. R., Hernandez, L.
Adoption of alien lambs by ewes bearing single natural offspring has been facilitated by the use of artificial odorants such as neatsfoot oil to establish a common odour for own and alien young and by the use of cloth stockinette jackets to exchange natural odours between lambs. The objective of...
