Fungal contamination of 92 feed samples used for milking cows feeding during one research year (in all seasons) in Vojvodina was examined. A special attention was paid to the frequency of A. fumigatus, a fungal species harmful to human and animals. As it was found out all feed samples in summer and spring were contaminated with fungi and about 95% in autumn and winter period. Aspergilli occurred as contaminants in all seasons. About 63% of feed samples in summer, 67% in autumn, 89% in winter and 48% in spring were contaminated with them. A. fumigatus was constantly present in feeds. It was isolated from 19% of feed samples investigated in summer, 33% in autumn, even 61% in winter and from 4% in spring

This research aimed to investigate the influence of different age of Podolian grey steppe and Holstein Friesian cows, as well as the effects of different breeds on their hematological and biochemical blood profile. A total of 128 adult cows aged from 3 to 12 years were used in the study. Gained results show statistically significant differences (P < 0.05) regarding all hematological parameters. The concentration of NE was recorded in the optimal range for Podolian grey steppe cows, while for Holstein Friesian breed was elevated.Values for LY was in the optimal range, while the values for MO, EO, and BA were slightly higher for both breeds of cow in all groups, with recorded significant differences (P < 0.05).Count of RBC in the Podolian grey steppe breed ranged between 5.83 and 11.21×1012/L, with significant influence (P < 0.05) of cows age in obtained values. In contrast, Holstein Friesian cows breed recorded RBC values lover then optimal, without any significant difference (P > 0.05) related to the age of cows. Total protein has ranged between 7.10 and 8.50 g/dl (Podolian grey steppe), and 8.13 to 8.48 g/dl (Holstein Friesian), without recorded statistically significant differences (P > 0.05) between the age, breed as well as the interaction of age and breed. Asimilar tendency can be seen regarding the otherbiochemical values (P>0.05), respectively.Gain results have mainly shown a significant influence of breed on the parameters above, while the significant influence of age of cows was not present as well the interaction between age and breed.

The paper presents the investigation of slaughter results, i.e. meat production and correlation between slaughter traits of kids of Balkan goat breed. Results of the study of slaughter properties are presented in this paper, also correlation between certain measures on carcass established in 96 kids of Domestic Balkan breed (gender ratio 50:50), slaughtered at the age of 90 days. Average dressing percentage of warm carcass with head and offal of investigated kid population was 58.19%, whereas the value of the dressing percentage of cold carcass with head and offal was 45.19%. Male kids had statistically significantly (P
