DEFINING THE BREED STANDARDS AND BREEDING GOALS FOR DOMESTIC MOUNTAIN HORSE

Domestic mountain horse is a transpoundary breed present in many Balkan countries. According to the Low of Animal Production of R. of Macedonia from 2008, for every breed of domestic animal in our state is nessesery to create a separate breeding program. In 2013 in low of animal production the autohtonous breeds of equidaes are added two new varietes - domestic mountain horse and domestic donkey. Facing the obtained results from estimating the main morphological, reproductive and functional traits in 220 domestic mountain horses in central mountain part of Macedonia during 2015 and 2016, the current standards and breeding goals were defined for the next national breeding program of this breed. According to the fact that the domestic mountain horse is a metapopulation and transboundary breed of horse in almost all Balkan countries, it is a good recommendation to create a regional breeding program with flexible standards and breeding goals for this breed of horses for all Balkan countries together

Aspects of harmonisation of individual monitoring for external radiation in Europe: Conclusions of a EURADOS action

Following the publication of the EU Council Directive 96/29, EURADOS coordinated two working groups (WGs) for promoting the process of harmonisation on individual monitoring of occupationally exposed persons in Europe. An overview of the major findings of the second WG is presented. Information on the technical and quality standards and on the accreditation and approval procedures has been compiled. The catalogue of dosimetric services has been updated and extended. An overview of national regulations and standards for protection from radon and other natural sources in workplaces has been made, attempting to combine the results from individual monitoring for external, internal and workplace monitoring. A first status description of the active personal dosemeters, including legislative and technical information, and their implementation has been made. The importance of practical factors on the uncertainty in the dose measurement has been estimated. Even if a big progress has been made towards harmonisation, there is still work to be don

A preliminary case study of the effect of shoe-wearing on the biomechanics of a horse's foot

Horse racing is a multi-billion-dollar industry that has raised welfare concerns due to disabled and euthanized animals. Whilst the cause of musculoskeletal injuries that lead to horse morbidity and mortality is multifactorial, pre-existing pathologies, increased speeds and substrate of the racecourse are likely contributors to foot disease. The hooves of horses have the ability to naturally deform during locomotion and dissipate locomotor stresses, yet farriery approaches are utilised to increase performance and protect hooves from wear. Previous studies have assessed the effect of different shoe designs on locomotor performance; however, no biomechanical study has hitherto measured the effect of horseshoes on the stresses of the foot skeleton in vivo. As there is a need to reduce musculoskeletal injuries in racing and training horses, it is crucial to understand the natural function of the feet of horses and how this is influenced by shoe design. This preliminary study introduces a novel combination of three-dimensional data from biplanar radiography, inverse dynamics, and finite element analysis (FEA) to evaluate the effect of a stainless steel shoe on the function of a Thoroughbred horse's front foot during walking. Our results show that the stainless steel shoe increases craniocaudal, mediolateral and vertical GRFs at mid-stance. We document a similar pattern of flexion-extension in the PIP (pastern) and DIP (coffin) joint between the unshod and shod conditions, yet variation in the degrees of rotations are encountered throughout the stance phase. In particular, in both the shod and unshod conditions, the PIP joint extends between the 10-40% of the stance phase and flexes before mid-stance and until the end of the stance phase. Similarly the DIP joint extends until the 40% of stance and then flexes until the end of the stance phase. Overall at mid-stance the PIP joint extends more at the shod (-2.9o) than the unshod (-1.5o) horse, whilst the DIP joint extends more at the unshod (-3.6o), than the shod (-2.8o) condition. We also document that the DIP joint flexes more than the PIP after mid-stance and until the end of the stance in both conditions. Our FEA results show increased von Mises stresses on the fore foot phalanges in the shod condition at midstance, indicating that the steel shoe increases mechanical loading. Our preliminary study illustrates how the shoe may influence the dynamics and mechanics of a Thoroughbred horse's forefoot during slow walking, but more research is needed to quantify the effect of the shoe on the equine forefoot during the whole stance phase, at faster speeds/gaits and with more individuals as well as with a similar focus on the hind feet. We anticipate that our preliminary analysis using advanced methodological approaches will pave the way for new directions in research on the form/function relationship of the equine foot, with the ultimate goal to minimise foot injuries and improve animal health and welfare.
