Evaluation of Lactobacillus Fermented Chicken Feather Meal on Blood Lipoproteins and Lymphocyte Count in Rats

This study investigates the impact of Lactobacillus fermented chicken feather meal on blood lipoproteins and lymphocytes in rats using in vivo techniques, researchers evaluated the effects of fermented feeds on rats, utilizing Lactobacillus acidophilus strain DSN20079 (LADSM) as the fermenter. The study showed significant decreases (P<0.05) in lipid profiles: Cholesterol: 147.50 mg/dL; LDL-C: 28.45 mg/dL; HDL-C: 64.15 mg/dL and triglycerides: 91.75 mg/dL. Blood lymphocyte count analysis revealed that dexamethasone (200 mg/g) significantly reduced lymphocyte count to 113.82 (P<0.05), levamisole (50 mg/g) increased lymphocyte count to 273.15 (P<0.05) and treatment with 100 mg/g of chicken feather meal increased lymphocyte count to 271.86, although this change was non-significant (P>0.05) compared to the levamisole group. The study concludes that Lactobacillus fermented chicken feather meal exhibits pronounced activity in modulating lipoproteins and blood lymphocytes, suggesting potential benefits for cardiovascular health and immune function. These findings highlight the potential of fermented chicken feather meal as a valuable feed supplement.
