Scientific knowledge about the predispositions of Bosnian native breeds of sheep (Dubska) for the production of milk and milk products until recently were quite sparse and very scarce. Therefore, the aim of this study was to investigate the biochemical indicators and serum minerals, for monitoring the nutritional status. Until now subject research did not include testing of the effect of biochemical parameters and hormonal status of the blood of sheep on the quality of milk and milk products. Persistence of this connection is justified by the fact that most of the ingredients of milk just derived from the blood. The main objective of this research was to explore metabolic parameters of sheep’s blood, and their relative importance on the quality and quantity of milk components. The study included a total of 127 sheep blood samples from two different areas (Livno and Travnik) in summer feeding period (July, August and September). The animals were marked with the appropriate number of ear tags on the basis of which we always took samples from the same animals through different periods. In sheep blood serum, the concentration of biochemical parameters (glucose, cholesterol, triglycerides, total protein, albumin, urea, AST, ALT, AP, GGT, LDH, calcium, phosphorus and magnesium) and metabolic hormones (triiodothyronine, thyroxine, and insulin cortisol), and samples of milk: milk parameters (milk fat, lactose and protein) as well as fatty acid composition of the milk. The concentrations of blood biochemical parameters were determined by spectrophotometry with automated analysis with ready-made package of slides. Concentrations of metabolic hormones (T3, T4, cortisol and insulin) in the serum were determined by ELISA method. The percentages of fat, protein and lactose in milk were determined by infrared spectrophotometry. Fatty acids in milk were determined by gas chromatography (GC). Our research showed hypoglicemia, mild hypoproteinemia and hypoalbuminemia probably due to nutritional deificiencies during lactation period. Negative energy balance could be responsabile for changes found in the cholesterol concentration as well as in the activity of ALT, AST, GGT, LDH. Significant differences in milk fat and milk protein, as well as fatty acids composition were determined between localities and season sampling. In general, our results showed varriation of blood biochemistry and milk quality. Due to differencies in climate, botanical differences of soil and pasture these variations are considered to be acceptable. Statistical analysis was performed using the software package SPSS 15.00 (for biochemical paramters and parameters of milk) and 21.00 (for metabolic hormones and fatty acid composition of the milk).

Iodine is an essential element to humans and animals. It is a constituent of the thyroid hormones and its deficiency causes goitre and may increase the risk for intellectual deficiency in affected populations. Iodine deficiency disorders represent a significant public health problem in 118 countries worldwide (Vitti et al., 2001). Among them, thirty-two European countries were still affected by mild to Abstract

Croatian scholarship is poorly acquainted with the life of the well-known Berlin architect, designer and professor, Selman Selmanagic. The enviable and lengthy career of this successful Bosniak and his exciting and dynamic life, intersecting with different cultures, certainly warrants attention, especially considering the contemporary research into the legacy of the Bauhaus tradition and the modes of its reception in Eastern Europe. Selman Selmanagic was the only Yugoslav who did his entire degree in architecture at Bauhaus. For twenty years he led the Department of Architecture at the Kunsthochschule in Berlin, and through his work influenced not only the education of students of architecture but of all other fields. Through his long professorial career, Selman Selmanagic marked many generations of his students and colleagues equally by promoting the idea of a single curriculum which encapsulated architecture, design, applied and decorative arts, technology and science – “totalen Architektur.” It is interesting that in the 1930s he spent some time in the Near East and that he collaborated with, among others, the studio of Richard Kauffmann in Jerusalem precisely when a significant number of his Bauhaus colleagues emigrated to the then Palestine, and when a specific variety of European architectural modernism, and through that the Bauhaus tradition, was being interpreted creatively in this region. Of particular significance was his participation in the Planungskollektiv team (the planning team), together with a number of distinguished architects, many of whom attended Bauhaus and were his colleagues in the anti-Nazi movement, from 1945 to 1950 which, led by Hans Scharoun, planned the post-war rebuilding of Berlin, where Selmanagic was at the head of the Department for the Planning of Building and Renovation of Cultural and Sports Structures, and for the Protection of Monuments (Leiter des Referats fur Kultur- und Erholungsstatten-plannung). As well as working as a professor and architect, he was an urbanist, a set designer and a very successful and established designer. Some of his designs have secured him a place as one of the classic figures of twentieth-century architecture. He extensively advocated the Bauhaus ideas and aesthetics in furniture design and interior decoration. It is of particular interest that he actively took part as a main consultant in the renovation project of the Bauhaus building in Dessau in 1975.

Modern breeds of dairy animals are able to produce huge amount of milk. In attempt to consume, digest and metabolize enough nutrients to satisfy lactation needs, those animals are exposed to serious stress conditions that can affect their health. Health problems which arise from those conditions are mainly related to impaired ability to metabolize enough nutrients to compensate for those lost in milk. They are known as metabolic or production diseases and may be of great economic importance in milk production systems.
