This research aimed to determine the positive effects of GP supplementation on growth and intestinal function in LPS-challenged broilers. The results showed that GP supplementation improved the weight loss rate, immunity, antioxidant function, and intestinal barrier function in broilers challenged with LPS. GP supplementation could act as a natural alternative to antibiotics to alleviate the negative effects of LPS challenge on broilers by improving their immunity and intestinal function.
Simple Summary This research was performed to determine the positive effects of GP on growth and intestinal function in lipopolysaccharide (LPS) challenged broilers. Results show that LPS challenge enhanced the weight loss rate, decreased the immunity and antioxidant capability, increased the intestinal permeability in broilers. When compared with LPS group, broilers fed with GP exhibited improved weight loss rate and jejunum villus height, enhanced ileum antioxidant function, and ameliorated intestinal barrier function. The LPS-challenged broilers in GP group had higher immunity than that of broilers in antibiotics group. In conclusion, GP supplementation could act as a natural alternative to antibiotic additive to alleviate the LPS-induced weight loss rate, inflammatory responses, and oxidative stress in broilers by improving the immunity and intestinal function. Garlic powder (GP) has the outstanding antibacterial, antifungal, antiviral, anti-parasitic and antioxidant characteristics because of its various contained bioactive components, such as alliin, allicin, and polysaccharide, etc. It has been widely used as a native medicine and shown to prevent a variety of diseases. This research was performed to determine the positive effects of GP on growth and intestinal function in lipopolysaccharide (LPS) challenged broilers. A total of 480 one-day-old male Ross 308 broilers of similar initial body weight were randomly divided into four groups with 8 replicates per treatment and 15 chicks each replicate. LPS challenge enhanced the weight loss rate, decreased the immunity and antioxidant capability, increased the intestinal permeability in broilers. When compared with LPS group, broilers fed with GP exhibited improved weight loss rate and jejunum villus height, enhanced ileum antioxidant function, and ameliorated intestinal barrier function. The LPS-challenged broilers in GP group had higher immunity than that of broilers in antibiotics group. GP supplementation could act as a natural alternative to antibiotic additive to alleviate the LPS-induced weight loss rate, inflammatory responses, and oxidative stress in broilers by improving the immunity and intestinal function.
