Megjegyzések:	The aim of this study was to estimate the occurrence of bacterial infection and contamination in two ostrich-producing farms. Compared to other poultry species, the hatchability of ostrich eggs is especially low. In a quest to identify factors that may affect hatchability, we collected faecal samples from adult birds, as well as eggs with dead-in-shell embryos, dead chicks and swab samples from the surface of the eggs and from the environment. The samples were screened for the presence of bacteria by routine bacteriological culture methods. The most prevalent bacteria, detected in the samples, were Escherichia coli, Bacillus spp. and coliform bacteria, whereas Pseudomonas spp. were less frequently found. The intensity and species compositon of the bacterial contamination was comparable in the two farms. Our results revealed that the bacteria, present in the environment, may likely be transmitted to the surface of the eggs. If they are able to penetrate the shell then the embryos and chicks become infected easily. These findings draw the attention to the special importance of enforcing efficient decontamination and disinfection measures to keep the environment and egg surface free from germs. Besides the appropriate egg treatment procedure, the incubation and hatching technology should also be kept under control.

Cím:	Effect of Different Supplementary Diets on Growing Rate, Fat and Protein Contents of Flesh Common Carp (Cyprinus carpio) Fingerlings / Zaheri-Abdehvand Sabouran, Csorvási Éva, Bársony Péter, Komlósi István, Szabó Csaba, Pusztahelyi Tünde

Megjegyzések:	The effect of different supplementary diets containing humic substances and probiotics for common carp, based on growth rate, specific growth rate %, protein and fat content was investigated. Humic acid was mixed with different mineral elements and the gram-positive bacteria combined as probiotics supplementary diets. These supplements were added to the experimental basal diet (control) at a rate of 0.5%, 1% and 2%. Four groups of fingerling with an average mass of 0.5 g were fed on the experimental diets, three times per day for 11 weeks. 30 fish per tank were weighed randomly every week to measure their growth rate and at the end of the experiment, 5 fish from each treatment were weighed and their fat and protein content was analyzed individually. The results showed that 1% and 2% probiotics increased the growth rate while all treatments have less specific growth rate % than control. In relation to fat and protein contents, the results showed that fish fed with probiotics 1% had high fat and protein contents compared to other groups in general. All fish fed with different levels of supplemented diets showed a decrease in fat in compare with control group. However, protein contents in fish fed with HS 0.5% and probiotics 1% were significantly higher than control and other group of fish fed with different level of supplemented diets. These results suggest that humic acid substances cannot improve fish growth rate, but fat and protein contents could be changed slightly, while probiotic supplementary diets can improve growing rates, having a significant effect on protein content of fish meat.
