Classifying the posture and activity of ewes and lambs using accelerometers and machine learning on a commercial flock
Contributor(s):: Price, Emily, Langford, Joss, Fawcett, Tim W., Wilson, Alastair J., Croft, Darren P.
Early decision making in commercial livestock systems is key to maximising animal welfare and production. Detailed information on an animal’s phenotype is needed to facilitate this, but can be difficult to obtain in a commercial setting. Research into the use of bio-logging on sheep to...

Assessment of meat-type sheep welfare using animal-based measures
| Contributor(s):: M'Hamdi, N., Darej, C., Attia, K., Guesmi, H., Znaidi, I. E. A., Bouraoui, R., M'Hamdi, H., Marzouki, L., Ayadi, M.
This study aimed to assess the welfare of Tunisian sheep in extensive sheep production systems using animal-based measures of ewe welfare. This study encompasses the first national survey of sheep welfare in which animal-based outcomes were tested. Animal-based welfare measures were derived from...

Duration of phase II of labour negatively affects maternal behaviour and lamb viability in wool-type primiparous ewes under extensive rearing
| Contributor(s):: Regueiro, Mariel, López-Mazz, Carlos, Jorge-Smeding, Ezequiel, Baldi, Fernando, Banchero, Georgget
This study determined to what extent the duration of labour phase II under extensive rearing would affect lamb viability and maternal behaviour in primiparous (P) single-bearing Corriedale ewes (n = 63). Multiparous (M) ewes (n = 116) were used as control category, reared under the same...

Compared to grouped lambing, isolation favorize calmer animals and faster mother-lamb recognition but not lambs’ survival in tropical hair sheep farms
| Contributor(s):: Escobedo-Canul, Juan A., González-Pech, Pedro G., Sandoval-Castro, Carlos A., Cámara-Sarmiento, Ramón, Sarmiento-Franco, Luis
The aim of this study was to compare the mother-lamb bonding and lamb mortality observed on Pelibuey ewes lambing in isolation (IL) or group (GL) under tropical farm conditions. Each treatment was conformed with 16 adults multiparous Pelibuey ewes of similar weight (39.8 ± 8.01 kg) and body...

Sheep Farmers' Perception of Welfare and Pain Associated with Routine Husbandry Practices in Chile
| Contributor(s):: Cristian Larrondo, Hedie Bustamante, Carmen Gallo
Considering the public concern about the welfare of farm animals during routine husbandry practices, this study aimed to determine how husbandry practices are carried out in Chilean farms, sheep farmers’ perceptions of animal welfare and pain, and factors that affect them, as well as the...

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...

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....
