Effect of Polysaccharide Gel Extracted from Durio zibethinus Rind on Immune Responses, Bacteria Counts and Cholesterol Quantities in Chickens

摘要: Polysaccharide gel (PG) from the rind of durian ( Durio zibethinus Murr.) is a soluble powder that gives good results as an excipient in pharmacological and food preparation. The aim present study was to evaluate effects PG feed-supplement diet on body weight gain, immune stimulation, total bacteria Salmonella feces, cholesterol levels broilers. Eighty, one-day-old broiler chicks were divided into 4 groups. Three experimental groups fed commercial coated with 1, 2 3 g/100 g, respectively, control group without PG. performed for 42 days. Chicken gain treatment not significantly different. At six weeks old, hemagglutination inhibition ELISA antibody titers against Newcastle disease (ND) virus infectious bursal (IBD) virus, respectively,were different (p < 0.05). chickens feed g revealed highest ND IBD. There no significant difference heterophil : lymphocyte ratio between group. count chicken feces reduced, 81-97%, compared Moreover, suspected colonies reduced 0.05) detected plasma lower than those Furthermore, content muscles broilers Therefore, polysaccharide benefited health promotion antibacterial activity, immunostimulant reduction.
