Physicochemical Properties and Feeding Effects of Fermentation Bed Formulated with Varied Amounts of Powdered Coconut Shells and Edible Fungi Waste

Coconut shell powder(CSP) and edible fungi waste(EFW) were used in formulating fermentation bed to produce material for hog feeding.Physicochemical properties including temperature,pH,electrical conductivity,salinity and microbial content of the fermentation bed,as well as the result of the subsequent hog-feeding,were used to optimize the fermentation process and feed formulation.When CSP∶EFW = 2∶1(v/v),the feeding results similar to the control(i.e.,chaff∶sawdust=1∶1) were obtained under otherwise same conditions.It was thus classified with the control in a same category at λ=1.5.As the CSP∶EFW ratio of 1∶1 was applied,it could be classified with the control at λ=8.75.The hog-feeding experiments with the materials showed that better sensory and meat quality were detected in the treatments than the control.And,the most desirable results in raising the pigs were observed when the feed was formulated with a CSP∶EFR ratio of 2∶1,followed by the ratio of 1∶1.
