The paper presents the results of the research realised upon 20 samples of feed/food, from which: 12 TMR destined for different morpho-productive categories of poultry (meat chicken, layer hens, reproduction hens); 2 - TMR for feeding pigs; 1 - concentrated feeding stuff for dairy cows; 7 - simple feed/food (wheat flour, maize meal, carrots, beet). The majority of the analysis were made at the request of some farmers from the area of Transylvania, as a result of the occurrence of some health disturbances in animals, being doubted that in their etiology was implicated the feed quality. The working procedures foresaw: the epizootic investigation in the farms from which the samples were taken, the macroscopic and stereo-microscopic examination of the feed, the raw chemical composition (after Weende methodology), the estimation of the nutritive value based on the raw chemical composition data and expressed through feed units oat, the mycological examination (cultivation on solid Sabouraud medium, counting of the colonies from the medium surface after 3 days and from the profoundness after 6 days of incubations at the temperature of 24 °C) and the identifications of the dominant mycets species by the examination of the cultural and morphological characters in slide preparations coloured with cotton bleu. Simultaneously there were determined the fats freshness (acidity value) in 13 samples and the proteins freshness (free ammonia content) in 3 samples. The obtained results emphasised the followings: the water content was between 13.45 % and 17.28 % in 14 of the total 17 samples of feed/concentrated food. The nutritive value was variable, being dependently of the dry matter content and of the structure of the feed. The myco-bacteriological Charge was increased, being in the 17 samples upon the limits foreseen by the quality norms. The dominant mycets species belonged to Fusarium, Aspergillus, Penicillium, Mucorales (known as potentially mycotoxigenic). .....
