Abstract:
... The present review discusses interactions and focuses in the direct effects of parasites in production of milk and development of mastitis in ewes. In most relevant published studies, a clear reduction in milk yield of ewes affected with parasites has been recorded. This reduction in milk yield has been quantified to average 22% among the relevant studies. Nematode parasitism can also cause shorte ...

Subject:
defense mechanisms; lambs; mixed infection; pathogens
Abstract:
... The ovine respiratory complex is an etiologically complex disease, occurring as a result of an interaction of the infectious agents with the host defence mechanisms, which are often compromised by environmental and management factors. There may be several combinations of contributors that are sufficient to produce disease, with variable importance of an individual factor with the presence of other ...

Abstract:
... The effects of subclinical intramammary infection (SCIMI) in sheep are ignored in most cases by both the farmers and the industry. Due to the high prevalence of coagulase negative staphylococci (CNS) and the lack of feasibility to treat the infection during lactation, prominent actions must concentrate on its prevention. On the sheep level, SCIMI caused by CNS clearly reduces milk yield and change ...

Abstract:
... Sheep milk contains a large number of antioxidant molecules, such as whey proteins, vitamins, fatty acids and others. In sheep milk the oxidation process is naturally balanced by the presence of constitutive antioxidant agents, however, the abundance of this antioxidant compounds depends also by the stressor conditions to which animal can be exposed. The stage of lactation together with particular ...

Implementing a vaccination plan against ORC requires: involvement of all farm staff, recording data, a positive cost:benefit analysis and continuous monitoring over time. Licensed vaccines for sheep are on ...
