Brazilian Journal of Poultry Science Revista Brasileira de Ciência Avícola Organic Egg Production, Egg Quality, Calcium ISSN 1516-635X Oct - Dec 2018 / v.20 / n.4 / 717-724 Utilization, and Digestibility in Laying Hens Fed with Mushroom (Flammulina velutipes) Stem Waste http://dx.doi.org/10.1590/1806-9061-2018-0756 Author(s) ABSTRACT Mahfuz SI,II https://orcid.org/0000-0001-8191-3028 The possibility of using mushroom (Flammulina velutipes) stem waste Song HI,III https://orcid.org/0000-0002-4505-9204 (FVW) in layer diets was explored in this study. A total of 180, 40-week- Wei JI Chen MI old ISA Brown laying hens were randomly assigned to 5 groups, with Zhen DI Nahar JIV 6 replications of 6 birds for each group. Layers were fed a standard Liu ZIV basal diet as control; antibiotic (0.05% flavomycin); 2% FVW; 4%FVW; I School of Life Science, Jilin Agricultural University, and 6% FVW. No significant differences (p>0.05) were observed on Changchun-130118, Jilin, China. II Department of Animal Nutrition, Sylhet hen daily egg production, egg weight, egg mass, unmarketable eggs, Agricultural University, Sylhet-3100, Bangladesh. feed intake, feed conversion ratio, and live weight among experimental III Engineering Research Center of Chinese Ministry of Education for Edible and Medicinal Fungi, groups. Haugh unit was found higher (p<0.05) in FVW fed groups than Changchun-130118, Jilin, China. in antibiotic fed groups. Shape index, shell weight, shell thickness, yolk IV College of Chinese Medicine Materials, Jilin Agricultural University, Changchun-130118, Jilin, weight, yolk index, yolk weight and albumen weight were not affected China.
