Abstract: (41 Views) |
Niacin (B3) and vitamins in malt extract play an important role in the metabolism and energy production process in cells. 300 Siberian fish with an average initial weight of 50±0.16 grams were treated in 8 experimental groups, each with 3 replicates, in 24 500-liter circular fiberglass tanks containing 10 fish equipped with aerators with central water discharge in a fully controlled manner for 8 weeks. Daily feeding to satiety was performed in the first control group (F) with common food, the second group with malt extract (ME) diet at 1% (M1), the third group with 1.5% (ME) diet (M2), the fourth group with niacin (B3) diet (20 mg kg-1) (B20), the fifth group with B3 diet (30 mg kg-1) (B30), the sixth group with 1% ME diet (B3 ± 120 mg kg-1) (M1+B20), the seventh group with 1.5% ME diet (B3 ± 130 mg kg-1) (M2+B30),, and the eighth group with 96% alcohol(Al96). The results of the study showed a significant difference in the biochemical indices of the blood of Siberian fry in the experimental treatments (p<0.05). In blood indices, the number of red blood cells (RBC) in treatment (B30) reached an average of 10606±850500 (× 103 mm−3 )and the number of white blood cells (WBC) in the same treatment reached 7050±44.97(× 103 mm−3 ), which indicates a significant increase. Also, the percentage of hemoglobin (Hb) in treatment (B30) reached 5.95±0.9 . In biochemical factors, the amount of glucose in treatment 3 with a level of 65±0.1 mg/dl, cortisol in treatments (M2)+(B30) with a level of 2.2±0.861 mg/dl, iron in treatments (M2)+(B30) with a level of 42.03±0.7 mg/dl, and cholesterol in treatment (Al96) with a level of 366±0.2 mg/dl had the highest values and created a significant difference with other treatments. The amount of sodium, potassium, and calcium did not showed significant difference with each other in the studied treatments. The results indicate the positive effects of different treatments on biochemical indices of fish blood. According to the results, the use of B3 1.5%± mg.kg-130 improves blood and biochemical indices.
