| الوصف: | The article presents the results of studies of morphological and biochemical blood parameters of carp juveniles when adding the extract Quercus cortex (1, 2, 3 mg/kg of feed), probiotic preparation of Soya-bifidum (0.7 ml/kg of feed), antibiotics Ciprofloxacin hydrochloride in the composition of the drug Antibak 250 (100 mg/kg of feed). Analysis of hematological parameters of carp juveniles showed that adding Quercus cortex extract to the diet at a dosage of 2 mg/kg of feed contributed to increasing SGE by 66%, the average concentration of hemoglobin in the red blood cell by 20% compared to the control group. An increase in the level of leukocytes compared to the control was recorded only in the IV experimental group and made 13% (P≤0.05). An increase in glucose in the groups receiving Quercus cortex extract has been stated: in the I experimental group- by 4.2 times (P≤0.001), in II – by 3.4 (P≤0.001) and in III – by 3.3 (P≤0.001) compared to the control. Increasing glucose concentration indicates active metabolic processes and better stress resistance in the fish body. Iron content in carp blood was higher only in the first experimental group (by 3 times) compared to the control. Increasing activity of alanine aminotransferase was observed in all experimental groups, the highest rate of this enzyme being recorded in the IV experimental group (feed with probiotic additive Soya-bifidum) with a significant excess of control by 48%. Lactate dehydrogenase enzyme activity exceeded the control in all experimental groups, maximum increase (by 67%) was observed in the IV experimental group. Alkaline phosphatase was below the control in all experimental groups, minimum values being registered in the IV experimental group- by 37% less than the control. Indicators of p-amylase in the IV group exceeded the control by 2.6 times, in the V group – by 1.5 times. In the II group p-amylase was lower than the control by 44%, and in the III – by 1.9 times. According to the obtained hematological data, it has been established that including Quercus cortex extract into the diet of carp juveniles is promising due to the positive effect on the fish physiological status, immune status, metabolic processes, hematopoiesis and digestibility of feed. |
