Abstract:
... It is generally recognized that sheep are susceptible to Toxoplasma gondii and play a very important role in the transmission of toxoplasmosis to humans. In China, sheep toxoplasmosis has been reported in some regions based on serological investigations. However, little is known about sheep toxoplasmosis in Shandong province, eastern China. Thus, this study was conducted to investigate the prevale ...

Abstract:
... The global population is becoming older, and still, this cohort considers red meat (beef and sheep meat) as an important staple in their diet. It is understood that the requirements from these red meats will vary as a person ages, often because of associated physiological changes; nutrition and health concerns; and reduced sensorial capacities. This creates an imperative to develop red meat produc ...

Abstract:
... Neosporosis is caused by infection with the protozoa Neospora caninum. It manifests as various neurological symptoms and is considered as one of the main causes of abortion in cattle, and induces uncommon congenital infection in sheep. The standard diagnosis is based on indirect immunofluorescence (IFI); however, cross-reactivity with other protozoa proteins is common. Aiming a more specific diagn ...

Since effective treatment and a vaccination procedure are not currently possible, control and eradication of the disease is difficult. It leads to serious economic losses around the world, therefore studies are currently underway ...

Abstract:
... Clostridium perfringens type D epsilon toxin (EXT) causes an important neurologic disorder of sheep, goats and, rarely, cattle. The disease can occur in peracute, acute, subacute, and chronic forms. High circulating levels of ETX produce vasculocentric brain lesions, in which microvascular endothelial injury results in diagnostically useful perivascular and intramural extravasations of plasma prot ...

Abstract:
... Bovine alphaherpesvirus 1 (BoHV-1) as a cusative agent for some diseases in cattle infects sheep and goat; and it is believed that these animals may be reservoir host for this virus. Thus, BoHV-1 infection in sheep and goat should be considerd when there is a program for control and eradication of this virus in cattle. Therefore, the aim of this study was to determine the seroprevalence of BoHV-1 ...

We attend to historical debates over the nature of the breed, whether it is extinct or not, and whether presently living exemplars are faithful copies of those that came before. We argue that there are features to t ...

Abstract:
... Measures of tooth wear have widespread use as proxies in palaeobiological reconstructions. In order to apply these proxies, an understanding of potential influence factors on wear is important. The processes during the digestion in the ruminant organism lead, possibly inadvertently, to a washing of material before it is regurgitated for rumination chewing. Therefore, ruminants might experience les ...

One function of embryonic signaling to the mother is to ensure that the CL is maintained. In ruminants, the secretion of uterine prostaglandin F2alpha (PGF2A) is the signal that initiates luteolysis. Despite many studies to determine if PGF2A secretion fr ...
