note = {Pangola grass (Digitaria eriantha Steud., synonym D. decumbens) is a high quality tropical grass and widely grown as pastures. It is utilized extensively for grazing, hay or silage making. The purpose of this study was to evaluate pangola grass in fresh, hay and silage form compared with fresh Napier grass (Pennisetum purpureum) and Ruzi grass (Brachiaria ruziziensis) as forage for ruminants. The first part of the study was to review pangola grass as forage for ruminant animals. According to the review, pangola grass has the potential to provide high quality feed for ruminant animals in tropical countries. Results obtained when pangola grass (in fresh, hay or silage form) was fed to ruminant animals as sole feed or supplement showed better performances in body weight gain, feed conversion ratio, carcass yield, meat quality, milk yield and composition compared with other forage or tropical grasses. The second part of the study was to assess its nutritive value and investigate nutrient digestibility, metabolisable energy and in vitro rumen fermentation kinetics in cross-bred native × Merino sheep (n = 16) fed pangola grass. Results showed that pangola silage (with addition of 5% molasses) was superior in terms of crude protein, crude fat, nutrient digestibility and metabolisable energy. In vitro gas production was highest (P<0.05) in pangola silage followed by – in that order – fresh pangola, pangola hay and Napier grass. The third part of the study was carried out to estimate in vitro gas production and dry matter intake, apparent digestibility, metabolisable energy and average daily gain in Thai indigenous cattle fed pangola grass. It was shown that pangola grass in different forms (fresh, hay and silage) can serve as the main component in the diets of growing White Lamphun native bulls (n = 16). Bulls fed pangola silage (with addition of 5% sugarcane molasses) diets had higher average daily weight gain compared to other treatments (P<0.05). In vitro gas production was highest (P<0.05) in pangola silage followed by – in that order – fresh pangola, pangola hay and Ruzi grass. Overall, results from these studies demonstrated that pangola grass is a feasible alternative as a good forage source and is regarded as high quality tropical grass and expected to be a valuable feed for ruminant animals. It can also be fed in conserved form as hay or silage to overcome feed shortage during dry season. The outcome of this study can be used as baseline data to introduce and promote pangola grass to smallholder farmers in order to improve animal productivity in Thailand and other tropical countries having similar environmental conditions and farming systems.},
