Key words : forage crop ,plant introduction ,evaluation ,yield ,nutritional value Introduction ‐ With traditional animal raising system in Northern Ch３i０n％a grassland areas , animals were winter fed with very poor quality‐forage , and had to consume body fat for survival . Up to of body weight loss was not a rare phenomena during winter spring season . The main purpose of this trial is to evaluate several newly introduced forage crops for their roles in supporting the animal production system in the central east Inner Mongolia , in terms of quality and quality . Materials and methods The study site is located in Balin Right Banner in Chifeng Municipality of Northern China . １T５en species ( varieties) of fo１ra５ge crops were evaluated in three locations . Seeds were‐ sown in late May/ early June with kg/ ha of diphosphate and kg / ha of urea as basal fertilizers . Fields were sprinkle irrigated for ensuring seedling emergency . Total fresh yields and main nutrient contents were measured for comparison and evaluatuion among the crops . Results and discussion １ Table summarized the main results of the trial . One forage maize showed superiority in yield in comparison with other crops . Most of Sudangrass X sorghum crops had average yields , but showed obvious high nutritional value , in terms of crude protein and crude fat contents .
