Antioxidant Status of Quails with the Complex Use of Probiotic and Zeolite
摘要
The study was conducted to determine the effect of the combined use of Enterococcus faecium RCAM05160 culture and synthetic zeolite NaX on the antioxidant status of Phoenix quail. In addition to the main diet, the experimental group of birds were given daily, from the age of 1 day, a suspension of E. faecium RCAM05160 culture with a cell concentration of 1 × 109 in 1 mL at a rate of 0.1 mL per 1 kg of live weight and synthetic zeolite NaX in an amount of 3% of the feed weight together with the main diet. The duration of the experiment was 42 days. The antioxidant status of the quail body was assessed by the following parameters: activity of superoxide dismutase, catalase, and ceruloplasmin; concentration of malonic dialdehyde; and antioxidant activity of blood plasma. In the experimental group, the activity of superoxide dismutase at the end of the observation period was statistically significantly higher than in the control group by 7.0%, catalase by 30.2%, and ceruloplasmin by 33.5%. The concentration of malondialdehyde, one of the main products of lipid peroxidation, was lower in the experimental group by 13.6% on the 42nd day of the experiment and the total antioxidant activity was higher by 20.7%. Throughout the experiment, the greatest increase in live weight was observed in quails of the experimental group. The yield of semieviscerated and eviscerated carcasses in the experimental group was higher by 6.67 and 9.49%, respectively. The combined use of E. faecium RCAM05160 culture and synthetic NaX-type zeolite in quail cultivation has a positive effect on the antioxidant status of quails, live weight dynamics, and meat productivity indicators.
