Differences in receptivity to gastrointestinal infections with nematodes in dairy ewes: Influence of age and of the level of milk production [PDF]

, 2005
Resistance to anthelmintics in populations of gastrointestinal nematodes is a major concern in small ruminants. One solution to limit the spread of anthelmintic resistance is to apply treatments selectively by targeting the most susceptible animals ...

Modification and expansion of existing body condition scoring scales for rabbits (Oryctolagus cuniculus) improves inter‐rater reliability when used by experienced raters

Veterinary Record, EarlyView.
Abstract Background Reliable body condition scoring in rabbits is essential in managing healthy bodyweight. The commonly used Rabbit size‐o‐meter (RSOM) has shown poor inter‐rater reliability, particularly among inexperienced raters. This study aimed to develop a reliable, reproducible body condition scoring scale for companion rabbits across breeds ...

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

Veterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.

Strategies for rapid rebreeding of lactating ewes in the spring

Animal, 2014
Rapid rebreeding of winter- and spring-lambing ewes is essential if ewes are to lamb more than once per year, but fertility of lactating ewes is often low and early weaning of lambs may be undesirable in forage-based production systems.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, EarlyView.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...
