Summary: The paper is a synthesis of the results obtained in researches over 5 years, made upon feed of different provenience from farms situated in the areas of Cluj and Alba.
Material and method: There were examined a number of 70 samples of feed. These were mostly sampled in farms were problems occurred in the production and health of animal, for which etiology was suspected the feed quality. Following laboratory determinations were made for all the feeds:
- the organoleptic characteristics (macroscopic, with the magnifier and the stereo-magnifier);
- it was also determined the raw chemical composition (using conventional methodology) and there were made quality chemical analysis (proteins freshness - expressed in quantity of free ammonia, fat's freshness - expressed in acid value, urease value in soy press cakes, total and partial acidity in ensilaged corn);
- bacteriological exams (TGN/g) and mycological exam (CFU/g), identification of the fungi with higher frequency. Mycotoxycological tests were made (RIDA QUICK Test) for DON identification.
The obtained result: The analyse of the experimental data emphasised that there occurred modification of organlopetic characteristics and of the raw chemical composition in over one third of the analysed feed samples. To the samples with increased water content there were constantly associated a high bacteriologic and mycotic charges. The dominant mycets were from the species: Fusarium, Aspergillus, Penicillium, Alternaria, Rhizopus, Mucor.
Over one third of the cereals samples, in which DON was determined by a quick test, were positive.
Conclusions and recommendations: The feeds with qualitative modifications were imvolved in the healthy deterioration and the decreasing of the production of the animal which were feed with these. The qualitative alteration of the feeds was caused by technological deficiency of processing, conditioning, as well as storage conditions. There is recommended to respect strictly the conditions and the control on the alimentary chain soilplant, animal-human, according to the principles of the HACCP system.
