Ruminal dry matter (DM), organic matter (OM) and crude protein (CP) degradabilities of poultry litter containing either rice hulls, peanuts hulls or corn cobs were estimated through in situ nylon bag technique with rumen fistulated heifers fed with corn silage and poultry litter. Statistical design was randomized blocks. The results showed that DM effective degradability of peanuts hulls poultry litter (70.07%) was similar to corn cobs (67.42%) and higher than (p<0.05) rice hulls (60.68%). Similar results were observed for OM (peanuts hulls: 67.66%; corn cobs: 67.43%; rice hulls: 60.74%). CP effective degradability of corn cobs poultry litter (78.39%) was lower than (p<0.05) peanuts hulls (83.23%) or rice hulls (83.97%). Peanuts hulls and corn cobs were better materials than rice hulls
