    EFFECT OF DIFFERENT SULFATED POLYSACCHARIDES (SEAWEED EXTRACTS) ON GROWTH PERFORMANCE, CARCASS CHARACTERISTICS AND GUT HEALTH IN BROILERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2022) ANITHA SRIRAM, C. R.; MALATHI, V.
    An experiment was conducted to study the effect of supplementing sulfated polysaccharides (Seaweed extracts) on production performance, lipid profile, immune response and gut health in broilers. A total of 360, day-old broiler chicks were randomly allocated to the eight experimental groups each containing 3 replicates with 15 birds in each replicate. Basal diet T1 was prepared using corn-soya diet without antibiotic. T2 was fed with basal diet with 0.03 per cent antibiotic. T3 was fed with basal diet with sulfated polysaccharide from red seaweed Kappaphycus alvarezii @ 250g/ton for 6 weeks. Treatment groups T4 and T5 were fed with control diet along with sulfated polysaccharide from Kappaphycus alvarezii @ 500g/ton for 4 and 6 weeks, respectively. Treatment groups T6, T7 and T8 were fed with control diet with sulfated polysaccharide from red seaweed Eucheuma denticulatum @ 250g/ton for 6 weeks, @500g/ton for 4 and 6 weeks, respectively. The results revealed that feeding sulfated polysaccharides resulted in significant improvement in body weight and feed efficiency. Inclusion of sulfated polysaccharides had no significant improvement on the immune response against Newcastle disease and Infectious bursal disease. Sulfated polysaccharides improved weight of lymphoid organs, significantly (P ≤ 0.05) reduced serum cholesterol, LDL, Triglycerides and increased HDL and total protein levels. There was no significant difference (P > 0.05) in dressing per cent, but significantly reduced (P ≤ 0.05) meat cholesterol levels and increased visceral organ weights and antioxidant status. Histopathology of duodenum, jejenum and ileum revealed higher number of villi per microscopic field, higher villi width and height in supplemented birds. It was concluded that feeding sulfated polysaccharides was beneficial in improving growth performance, gut health, antioxidant profile, lowering the serum cholesterol, LDL and improving serum HDL levels in broiler chicken.
