Dietary supplementation with chitosan oligosaccharide affects serum lipids and nutrient digestibility in broilers

This research was conducted to determine the effects of supplementation chitosan oligosaccharide (COS) on growth performance, blood parameters, carcass traits, fatty acid composition breast meat, and apparent nutrient digestibility in broiler chickens. A total 375 one-day-old Ross 308 male chicks were allocated a control diet (T1) or diets supplemented with 50 ppm (T2) 100 (T3) COS. There five replicates 25 for each treatment. All experimental birds fed starter (days 1 - 4), grower 15 28), finisher 29 42). No differences detected among treatments live weight, gain, feed intake conversion, except that depressed T3 during period. Serum protein albumin levels did not differ treatments. cholesterol, low density lipoproteins (LDL), very (VLDL) triglyceride concentrations reduced significantly by COS, whereas high lipoprotein (HDL) concentration lower only T2 relative T1. The dressing percentage higher than Fatty meat unaffected some its constituents affected graduated manner addition Thus, COS improved yield had hypolipidemic effect improving serum lipid profile
