microscopy as “field based test” was compared with is900 blood pcr for the diagnosis and estimationof prevalence of mycobacterium avium subspecies paratuberculosis (map) in domestic livestock withclinical johne’s disease (jd). of 252 animals screened, 39.3 and 13.1% were positive by faecal microscopyand blood pcr, respectively. proportional agreement between “microscopy” and blood pcr was subst...
In this paper the main epidemiological aspects of the major domestic ruminant trematode infections in Zimbabwe are reviewed and discussed with regard to the available options for control. Seasonal occurrence of amphistomes, Fasciola gigantica and Schistosoma mattheei are considered both in the definitive and intermediate hosts. The regional distribution of the trematodes is reviewed in relation...
Brucella is ┙-Proteobacteria causing an infectious disease in mammals that could be transmitted to humans. Ruminant and swine are prone to be infected by such microorganism all over the world, thus acting as a potential reservoir for domestic livestock and therefore, affecting humans. Brucella species differ in their hosts’ preference, physiological abilities and cell surface structural charact...
ing the integration of multiple feedback signals in the control of feeding behavior (Forbes, 1995, 1996). Because of During the history of ruminant nutrition many factors have been the experimental difficulties in the study of the central proposed as regulators of voluntary feed intake. In some cases, the implicit assumption has been that a factor acted independently and nervous system, the use...
Since the emergence of bovine spongiform encephalopathy (BSE) in the United Kingdom in the late 1980s, the United States has implemented various measures to prevent the disease from entering the country, to prevent its spread if discovered here, and to safeguard human health. Regulatory actions included import restrictions, a ban on certain ruminant tissues in ruminant feed, and a surveillance ...
Wild and domestic ruminants are susceptible to Bluetongue virus (BTV) infection. Three BTV serotypes (BTV-4, BTV-1 and BTV-8) have been detected in Spain in the last decade. Even though control strategies have been applied to livestock, BTV circulation has been frequently detected in wild ruminant populations in Spain. The aim of the present study is to assess the role for wild ruminants in mai...
Helminth infections of the gastrointestinal tract and lungs can lead to devastating economical losses to the pastoral based animal production. Farm animals can suffer from malnutrition, tissue damage, and blood loss resulting in impaired production traits and reproduction parameters. In Austria, pastures grazed by sheep, goats, and cattle overlap with the habitats of several species of wild cer...
Interleukin-4 (IL-4) produced from Th2 cells modulates both innate and adaptive immune responses. It is a common belief that wild animals possess better immunity against diseases than domestic and laboratory animals; however, the immune system of wild animals is not fully explored yet. Therefore, a comparative study was designed to explore the wildlife immunity through characterisation of IL-4 ...
Through natural development the ruminant stomach has achieved an efficient microbial digestion of plant fibre and also of almost all other plant constituents; synthesis of microbial polysaccharide and protein and of certain vitamins also occurs. The products of microbial digestion are utilized by ruminants, but they are not identical with the products of digestion in non-ruminants. I n this Sym...
Abstract With the increased interest in the ‘carbon footprint’ of global economic activities, civil society, governments and the private sector are calling into question the wisdom of transporting food products across continents instead of consuming locally produced food. While the proposition that local consumption will reduce one’s carbon footprint may seem obvious at first glance, this concl...
