Resumo: |
Active ingredients with antioxidant, anti-inflammatory, antimicrobial functions, among others, obtained from plants have been increasingly studied in search of alternatives that can replace synthetic products that have such effects, used as additives in animal feed. Plants rich in flavonoids stand out in these research, such as the genus Scutellaria baicalensis which is a herb traditionally used in Chinese medicine, which is composed of different flavonoids. The benefits of extracting this species have been observed in many human and animal studies, and specifically for poultry there are studies on broilers and laying hens. However, there is little research using it for Japanese quail. The objective of this study was to evaluate the zootechnical performance, quality of eggs of Japanese quails, receiving additive containing Scutellaria baicalensis extract added to the feed, as well as its antioxidant activity and determination of total flavonoids. 384 42-day-old Japanese quails were used, distributed in four treatments (0; 0.1; 0.2; 0.3% of the product containing Scutellaria in the diet) with six replications of 16 animals each. The design used was completely randomized (DIC). The experimental period was 126 days subdivided into four 21-day cycles. For egg quality analysis, variables such as: average egg weight (g), egg yolk, albumen and shell weight (g), shell thickness (mm), Haugh unit, yolk, albumen and shell index and percentage were evaluated. , specific gravity. The antioxidant activity of the product containing Scutellaria baicalensis was evaluated by FRAP, ABTS, DPPH methods and total flavonoids and total phenols were assayed. The collected data were submitted to ANOVA and Tukey test using the R computational package. The significance level of α = 0.05 was adopted. There were no statistically significant differences in egg performance and quality parameters, showing that the tested levels of the additive containing Scutellaria Baicalensis did not provide improvement or changes in these parameters for Japanese quails. The results of the five laboratory tests performed to evaluate the antioxidant capacity of the additive showed that it has antioxidant potential. |
