| Popis: | The purpose of this experiment is the evaluation of biochemical composition of Nile tilapia meat by administrating several phytobiotics in feed. Oreochromis niloticus, with an initial average weight of 125.41±34.33 g/exemplar, were reared, during six weeks in a recirculating aquaculture system. The phytobiotics from this experiment were administered in feed in a concentration of 1%/kg feed and consist in: thyme (Thymus vulgaris), fenugreek (Trigonela foenum graecum), neem (Azadirachta indica). Thus, the experimental variants were: V1-control, V2-thyme, V3-fenugreek and V4-neem. Fish were fed with SOPROFISH pelleted feed with 38% crude protein and 7% crude fat. During the experiment, the physico-chemical parameters of technological water were situated in normal range for optimal growth. At the end of the experiment, significant differences (p0.05; p=0.68). The highest value of moisture (87.25%) was registered in V2; the lowest value of fat content (0.05%) was recorded in V4 and the lowest protein content (10.79%) in V2. In conclusion, thyme, fenugreek and neem administration, in concentration of 1%/kg feed, influenced significantly the biochemical composition of Oreochromis niloticus. |
