Vaccine use in organic cattle and sheep systems: Development of a decision support tool based on risk assessment [PDF]

open access: yes, 2003
This project’s aim was to support a consistent approach to decision making on vaccine use among organic dairy, beef and sheep farmers and their advisers, including their veterinarians, by developing a decision support tool on vaccine use in order: a) to

Nairobi Sheep Disease

open access: yesParasitology, 1931
In 1917 Montgomery described a tick-borne gastro-enteritis of sheep and goats for which the name Nairobi sheep disease has passed into general use. In a comprehensive paper dealing with his work at Kabete he was able to show that the causal agent was a filtrable virus, transmitted by Rhipicephalus appendiculatus, the ordinary brown tick and common ...

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

open access: yesAdvanced Science, EarlyView.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Resilience of Small Beef Packers and the USDA Meat Supply Chain Initiative

open access: yesAgribusiness, EarlyView.
ABSTRACT We focus on the plant‐size resilience relationship among small beef packers during COVID‐19. Defining resilience as the ability to maintain or increase slaughter and non‐resilience as otherwise, we use survey and secondary data to estimate a logit model where resilience is a function of a plant's capacity and age in addition to labor condition

Bio‐to‐Robot Transfer of Fish Sensorimotor Dynamics via Interpretable Model

open access: yesAdvanced Intelligent Systems, EarlyView.
This study demonstrates how a biologically interpretable model trained on real‐fish muscle activity can accurately predict the motion of a robotic fish. By linking real‐fish sensorimotor dynamics with robotic fish, the work offers a transparent, data‐efficient framework for transferring biological intelligence to bioinspired robotic systems.

An in vitro study of the replication, morphology and DNA base composition of Mycoplasma ovipneumoniae : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University, New Zealand [PDF]

open access: yes, 1977
Mycoplasma ovipneumoniae can almost invariably be isolated from the lungs of sheep with chronic pneumonia, which is a prevalent disease in New Zealand hoggets.

Modeling chronic periodontitis in rats: Persistent alveolar bone loss mediated by periodontal pathogens

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

Heart rate variability analysis in sheep affected by transmissible spongiform encephalopathies

open access: yesBMC Research Notes, 2011
Background The function of the autonomic nervous system can be assessed by determining heart rate variability (HRV), which is impaired in some brainstem diseases in humans.

Prevalence of Anaplasma phagocytophilum infection and effect on lamb growth [PDF]

open access: yes, 2011
Background: A major challenge in sheep farming during the grazing season along the coast of south-western Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum that is transmitted by the tick Ixodes ricinus.
