Inspection on Three Plant Spices as an Animal Forage Source in Mazandran Wetland

G. Heydari, A. Teimouri Yansari and H. Zali
In order to evaluation of wetland plant spices as a forage source in animal nutrition, three species, Paspalum distichum, Sparganium erectum and Aeloropus litoralis that has vast cover in Mazandaran wetland was chosen. At the 30% of flowering, randomly, 3 kg of feed samples were taken and kept on -20oC, until that defreeze before chemical analysis. Chemical composition including crud protein (CP), crud fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), total digestible nutrients (TDN), digestible dry matter (DDM), predicted dry matter intake, relative forage value (RFV) and relative forage quality (RFQ) of feeds were calculated. Using two ruminal fistulated mature Zel sheep, NDF digestibility (% of NDF) were measured via in situ techniques. Dry matter, CP, CF, NDF, ADF, and ash content of three spices were significantly different. Aeloropus litoralis had the highest dry matter, CP, ADF, and ash, but Sparganium erectum had the highest CF, NDF. There were not significant different between NFC and ether extract content of three plant spices. Digestibility of NDF after 48-h ruminal incubation was significantly different and the values were 0.65, 0.63, and 0.66 % of NDF in Paspalum distichum, Sparganium erectum, and Aeloropus litoralis, respectively. However, digestible NDF (NDFD; % of NDF) had no difference in Paspalumdistichum, Sparganium erectum, and Aeloropus litoralis (45.68, 45.51 and 44.10% of NDF, respectively). TDN, DDM content of three spices and predicted DMI (% of BW) had not significant differences. The values of RFV and RFQ were significantly different in Paspalumdistichum, Sparganium erectum, and Aeloropus litoralis (118.08, 114.73 and 124.23; 143.26,116.32 and 136.27, respectively. It can be concluded that wetland grasses are high in NDF, but that fiber typically is highly digestible; therefore, wetland grasses may be evaluated more accurately when tested for RFQ instead of RFV.
