As a well-known protozoan zoonotic giardiasis has manifested itself with various clinical findings in mammal species including human and dogs. Absorption of some essential biochemical elements required to growth has interrupted in giardiasis being tight relationship with malnutrition. Thus, the aim of the present study was to determine the serum trace element levels in dogs infected with giardiasis. For this purpose, totally 16 dogs enrolled in the study and 8 of these had diarrhoea compatible with giardia (infected group) and others were grouped into healthy. Diagnosis of giardia was performed by microscopical evaluation of cysts and supported by rapid test from faecal samples. In the infected group, copper (Cu), magnesium (Mg) and zinc (Zn) levels had significant differences to healthy control. Giardia infected dogs had a significant increase in Cu and significantly reduces in Mg and Zn levels. It was thought that unclear mechanism of decreased Zn levels might be related to elevated Cu involving enzyme systems. And also, malabsorption and diarrhoea were proposed mechanism for altered Mg levels, which could counteract by blocking of intestinal absorption. Consequently, Cu, Mg and Zn levels were affected in giardiasis and the addable of these elements to the treatment should be revealed by further studies.

The objective of this study was to examine the nutritionally-related
blood metabolites; total protein and glucose levels in goats of Kinta and Hilir Perak districts. A total of eight farms were screened, involving a total of 220 animals. Serum samples were collected in plain tubes for total protein determination, while
plasma samples were collected in sodium fluoride tubes for glucose determination. Total protein and glucose determination were carried out using Idexx Vettest 8008 Blood Chemistry Analyzer. Results show
that goats in seven out of eight farms had malnutrition problems and poor body scores. Farmers were given advices based on the laboratory results obtained from this study.

The etiologic agents of mucormycosis are several nonpathogenic fungi of the order Mucorales and are ubiquitous. A total of 82 chickens were infected with the disease and developed anorexia, diarrhea, malnutrition, dyspnea, and paralysis in a chicken farm, Sokcho, Kwangwon. At necropsy there were multiple nodular lesions and hemorrhages in livers, spleens, kidneys, gastro intestinal track, and respiratory system. On histopathological examination it was found that the nodular lesions were consisted of granulomatous inflammation accompanying characteristic hyphae (4-24 micro wide) of the fungi

Belarus is among regions, where the selenium content in soil, hence, in cereal and other cultures considerably below requirements that leads to insufficiency of this microelements in a diet as the person, and animals. Synthesized in the All-Russian Scientific Research Institute of Physiology, Biochemistry and Feeding of Agricultural Animals new organic compound of selenium - selenopyran on variety of criteria has no analogues in the world among considerable quantity selenium of containing preparations and favourably differs from all known forms of microelements. Selenopyran, brought in fats and forages, shows antioxidatic the properties which are not conceding traditionally applied in veterinary science and medicine to antioxidants. Arriving in animal body with forage or in the form of injections, selenopyran is capable to play a role of a metabolic regulator. It activates enzymes of antioxidatic body protection, reduces formation new and will neutralize of earlier formed activeproducts of peroxide lipids oxidations, improves functioning of cellular membranes, normalizes metabolism, makes active cellular, humoral and phagocytal immunity links, raises nonspecific resistance and efficiency of animals. Toxicity of selenopyran more low, than at all known organic connections of selenium, and more than in 100 times is less, than at sodium selenit. The data allow to expand possibilities of application of organic selenium and to use it as a preparation raising resistance and body viability at the expense of the patronage of cellular structures from influence of oxidizers and free radicals, to normalize metabolism and to stimulate thus the big additional body weight at animals. The influence of medicine organic selenium on piglet bodies what are behind a growth and development is shown. The results showing the dynamical changes of haematologicals, physiologicals and biochemicals indices under the influence of selenopyran was given.
