Effects of Spent Oyster Mushroom (Pleurotus ostreatus) Substrates (SOMS) Supplementation in Broiler Diets on Apparent Nutrient Digestibility, Cecal Microbiology, Small Intestinal Histomorphology, Productive Performance, Carcass Characteristic, Quality and Fatty Acid Composition of Meat

Abstract

            This experiment was carried out to investigate the effects of spent oyster mushroom (Pleurotus ostreatus) substrate (SOMS) supplementation in broiler chicken diets on apparent nutrient digestibility, cecal microbiota, small intestinal morphology, productive performance, carcass quality and fatty acid composition in meat. Four hundred and eighty (240 male and 240 female), day-old, Ross 308^®. Chicks were raised under ambient temperature and assigned to complete randomized design (CRD) with four dietary treatments and three replications per treatment. Dietary treatment were, corn-soy basal diet supplemented with 0 (control), 1, 2, 3, 4 และ 5 % of SOMS. Experiment diets and drinking water were offered ad libitum to the bird. Result show that the inclusion of the SOMS decrease apparent digestibility of dry matter, ether extract, gross energy and crud protein (P<0.05). Dietary SOMS supplementation decrease villous height, cryptal depth and villous height to crypt depth ratio in duodenum of broiler (P>0.05). In addition, Experiment diet increase Lactic acid and Enterococcus sp. (P<0.05) and decreased Salmonella sp. And Escherichia coli in cecum of broiler (P<0.05). Dietary supplementation of SOMS in broiler diets may be a feasible means of producing meat with lower cholesterol contents for health conscious consumers. In conclusion, the result of the present study showed that supplemented 1-3 % of SOMS can be used and has the potential as feedstuff enhanced intestinal histomorphology and microbiology of broilers.
