Effect of dietary supplementation of enzyme-treated Scutellaria baicalensis on the growth performance, apparent ileal digestibility, intestinal morphology, and cecal microbiota in broiler chicks
Provisionally accepted- Linyi University, Linyi, China
The aim of this study was to assess the impact of dietary supplementation with β-glucuronidase-treated Scutellaria baicalensis extract (GTSB) on the growth performance, nutrient digestibility, intestinal morphology, and cecal bacteria of broiler chicks. A total of 432 broiler chicks (41.92 ± 0.19g) were used for this study. The birds were divided into three groups, each consisting of eight replicate cages. The experimental period was 35 days, during which the birds were fed a basal diet supplemented with 0%, 0.05%, or 0.10% GTSB. Following the 35-day feeding trial, it was observed that body weight gain and gain to feed ratio exhibited a linear increase with the dosage of GTSB in the diet. Furthermore, graded levels of GTSB supplementation positively influenced nutrient digestibility, as evidenced by a linear improvement in the digestibility of dry matter and crude protein. Additionally, GTSB supplementation resulted in an increase in cecal lactic acid bacteria and an enhancement of intestinal morphology. Therefore, the dietary supplementation of 0.10% GTSB was found to be an effective strategy for enhancing the growth performance of broilers by regulating intestinal morphology and increasing the population of beneficial bacteria.
