Association between the prion protein genotype and animal performance traits in a large multibreed sheep population

Animal, 2022
Genetic susceptibility to scrapie, a fatal disease of sheep and goats, is modulated by polymorphisms in the prion protein (PrP). Neither the frequency of the PrP genotypes nor their association with animal performance has been investigated in a large ...

Caffeine supplementation of ewes during lambing may increase lamb survival

Animal, 2018
Perinatal mortality of lambs is on average 20% of lambs born in extensive Australian grazing systems, constituting a substantial production loss and welfare concern. Hypoxia resulting from prolonged or difficult births contributes to lower rates of lamb survival, and caffeine may reduce the effects of hypoxia.

What does coexistence mean? Insight from place‐based trajectories of pastoralists and bears encounters in the Pyrenees

People and Nature, EarlyView.
Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

The effects of birth rank (single or twin) and dam age on the lifetime productive performance of female dual purpose sheep (Ovis aries) offspring in New Zealand.

PLoS ONE, 2019
Greater rates of genetic gain can be achieved by selecting animals born to younger parents. However, little is known about the lifetime performance of dual purpose ewes (Ovis aries) that are born to primiparous ewe lambs (8 to 9 months old at breeding ...

The use of feed blocks as supplementation for the upland hill flock: (2) Cost effective lamb production [PDF]

, 2002
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).Under EU organic livestock regulations introduced in 2000, new restrictions were placed on the use of bought-in feedstuffs in hill systems.

Using participatory scenario planning to explore the synergies and trade‐offs from upland treescape expansion

People and Nature, EarlyView.
Abstract The future of land use in the UK uplands is highly debated, with growing interest in increasing tree cover and other land use changes, alongside a desire to maintain traditional land use patterns and practices. Treescape expansion is likely to result in synergies and trade‐offs between different outcomes, so integrating stakeholder preferences

Udder skin temperature is related to the ewes’ and lambs’ behaviors at birth in autumn lambing ewes

Frontiers in Ethology
The survival of lambs depends on various factors, including the behavioral traits of both mother and newborn lambs at birth, as well as the ewe’s colostrum production and quality.

Influence of body weight on reproductive activity in Sarda female lambs

Italian Journal of Animal Science, 2010
One way to improve reproductive performance of ewes is through extending its lifetime productivity. Breeding ewe lambs is one method of improving the reproductive performance in the sheep.

Welfare implications of artificial rearing and early weaning in sheep

, 2008
In the present review the formation and resolution of the ewe–lamb bond under natural conditions are described . Thereafter, the effects of premature dam–lamb separation, performed through artificial rearing or early weaning on behavioural, endocrine and
