Influence of various dosages of probiotic "Cellobacterin-T" on biochemical indicators of chicken blood

Abstract

The article presents data from experimental studies on the effect of various dosages of the Cellobacterin-T probiotic in the diets of laying hens on hematological parameters. It was established that the use of the probiotic additive Cellobacterin-T in the compound feed at the rate of 100 mg/100 g contributed to an increase in the content of hemoglobin and erythrocytes at 30 weeks, respectively, by 2.2 and 13.3%; at 46 weeks - by 2.9 and 3.7%; at 64 weeks - 1.9 and 1.8% compared to the control group. The inclusion of the supplement somewhat changed the content of total protein in the blood serum, the level of protein in the blood was more at 30 weeks by 3.4%; at 46 weeks - by 3.9%; at 64 weeks - by 3.1%. To improve the physiological status of laying hens, it is recommended to include the probiotic feed additive "Cellobacterin-T" in the compound feed at a dosage of 100 mg/100 g of compound feed by stepwise mixing.
