Toxicological and histopathological investigations of tissues of commercially slaughtered chickens were carried out to provide a preliminary evaluation of the incidence of occurrence of ochratoxin A (OTA) in chicken sold in Serbian retail market. In addition, the etiology of nephropathies of these chickens was elucidated. The majority of these tissue samples were not found to contain measurable amounts of OTA. Moreover, the OTA levels found in analyzed tissues were generally low and there was no positive correlation between the presence of OTA and the frequency of histopathological changes. Histopathological changes such as degenerative changes in the kidneys and liver differed from the classical description of the mycotoxic nephropathy, indicating that the chicken nephropathy observed in Serbia may have a multitoxic etiology with possible synergistic effect between microorganisms and natural toxins, usually present in low concentrations. The low OTA results also suggested that chicken meat available in the retail market in Serbia are unlikely to pose any significant adverse health risk to the consumers with respect to OTA toxicity.

Species of the genus Fusarium are characterised by the exceptional intraspecies and interspecies variability in respect to morphological, physiological and genetic properties. Intraspecies and interspecies diversity of Fusarium verticillioides and Fusarium proliferatum isolates in the production of fumonisin B1 according to their origin from maize and wheat grains was studied. Fumonisin B1 production potential of investigated 42 isolates was assessed by HPTLC and ELISA method. All 22 and 20 investigated F. verticillioides and F. proliferatum isolates, respectively, had the ability to produce fumonisin B1 toxin. Fumonisin B1 production potential of F. verticillioides and F. proliferatum varied from 88.60 ppm to 1,300.60 ppm and from 2.37 ppm to 1,246.00 ppm, respectively. According to Mann-Whitnev U test, there were no significant differences between the fumonisin B1 production mean values of isolates of F. verticillioides originated from maize and wheat (628.13 ppm and 696.38 ppm, respectively), as well as, fumonisin B1 production mean values of F. proliferatum isolates (212.32 ppm and 158.07 ppm, respectively). Variability coefficient values indicated that fumonisin B1 production potential variability was more expressed in maize than wheat originated isolates for both species.

Poultry production is an important livestock sector in Serbia. It accounts for about 12% of the total value of country's livestock production. Providing relatively cheap food of high quality it is nowadays of particular importance due to economic transition problems and the consequent economic crisis that the country has faced since the beginning of the 1990s. However, despite the sector's importance, poultry production has actually had no institutional support for many years, and the poultry population, as well as broiler meat and table eggs production, has significantly declined over the last two decades. The sector is characterized by insufficient level of concentration, specialization, vertical integration and efficiency. It is estimated that small-scale farms and backyard poultry production in Serbia account for more than half of poultry meat production and two thirds of egg production, with a significant seasonal impact on local markets. The following paper gives an overview of both commercial and small-scale poultry production in Serbia and examine the major economic constrains to and opportunities for poultry sector improvement needed in view of Serbia's prospective EU integration. © World's Poultry Science Association 2010.

Proteins and lipids of muscle tissue are important meat quality parameters. They contribute substantially to the nutritional characteristics of meat. A number of studies has been conducted on the effect of different factors on the protein and lipid content of broiler meat. Given the above, the subject matter of the present paper was to provide a review of latest research results on the said quality traits as affected by the most commonly tested factors. The results were grouped and presented in terms of the effect of nutrition, genotype, sex, age and rearing system. The objective of the paper was to review major previous studies on the subject in an attempt to define a future research pathway and facilitate the promotion of scientific findings towards wider practical implementation. © 2010 Academic Journals.

The frequency and incidence of fungi, as well as their interdependence, on rachis and grain of 14 wheat cultivars grown under 19 different agroecological conditions in Serbia, were studied. Out of the 23 identified fungal genera, a significantly higher number of species was isolated and identified from rachides (22) than from kernels of wheat (9). Fusarium and Alternaria species were the most frequent (up to 100 %) species on both, rachides and kernels, but the incidence of these fungi were higher on rachides than on kernels. The most frequent of the 14 Fusarium species were F. graminearum (96. 8 % on both, rachides and kernels) and F. poae (93. 8 % on rachides and 51. 6 % on kernels). The frequency of F. verticillioides was significantly higher on rachides (64. 5 %) than on kernels (19. 4 %). A positive correlation (r = 0. 5356 **) was established between the frequency of F. graminearum on rachides and on kernels. Furthermore, the frequency of Alternaria spp. was also statistically higher on rachides than on kernels, but the correlation was not statistically significant (r = 0. 1729). The incidence of F. graminearum was negatively correlated with the incidence of Alternaria species in both, rachides (r = -0. 3783 *) and kernels (r = -0. 4863 **). These are the first data on the frequency and incidence of fungi on wheat rachides in Serbia, and they support the few data presented in the world literature. Results of this research could be useful for better understanding of pathways in a fungal infection and the improvement of wheat breeding for resistance, as well as, a proper application of fungicides in the wheat head protection. © 2012 KNPV.
