EVALUATING EXTENSIVE SHEEP FARMING SYSTEMS [PDF]
Data from each of 5 commercial, extensive sheep farms in Cumbria, UK were used as parameters in a linear program (LP) representing labour and grazing management in such farming systems.

Advanced Science, EarlyView.Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Endogenous betaretroviruses of sheep: teaching new lessons in retroviral interference and adaptation [PDF]
, 2004 The endogenous betaretroviruses of small ruminants offer an excellent model to investigate the biological relevance of endogenous retroviruses (ERVs). Approximately twenty copies of endogenous betaretroviruses (enJSRVs) are present in the genome of sheep

Labour Management for Profit and Welfare in Extensive Sheep Farming [PDF]
Sheep welfare is an emerging topic in research and food marketing, and recent studies suggest that farm labour is a key factor for both animal welfare and productivity in extensive sheep farming systems, although little research has been done into labour

Associations between worm egg count and production in Dorper sheep [PDF]
, 2008 With changes to the Australian sheep industry, breeds that have a meat emphasis are becoming increasingly adopted by farmers. One such breed is the Dorper sheep, which was used in this study to investigate the relationship between worm egg count and ...

Prion protein in the cerebrospinal fluid of healthy and naturally scrapie-affected sheep [PDF]
, 2006 The aim of this study was to characterize the cerebrospinal fluid (CSF) prion protein (PrP) of healthy and naturally scrapie-affected sheep. The soluble form of CSF PrPC immunoblotted with an anti-octarepeat and an anti-C terminus mAb showed two isoforms

Advanced Science, EarlyView.SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Effects of prenatal undernutrition on emotional reactivity and cognitive flexibility in adult sheep
, 2004 The experiment reported was designed to test two hypotheses: that prenatal undernutrition (a) increases emotional reactivity and (b) impairs cognitive flexibility in sheep. The mothers of one group were fed live weight maintenance requirements throughout

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue
Advanced Science, EarlyView.This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...
