| Abstract: | Objective： Determination of content of varies nutrients in hybrid giant napeir （Ponnisetum hydridum） · Methods： Determination of crude protein content by the Kjeldahl method; according to GB/T 6433 - 2006/ISO 6492：1999 ＂feed fat determination＂ be fat measurement; Determination of crude fiber using GB/T6434 -94 methods; measure the ash according to GB6438 -92; nitrogen -free extract% = 100% - （moisture ＋ ash ＋ crude protein ＋ fat ＋ crude fiber） %. By flame atomic absorption spectrophotometer content of the sample in sodium, potassium, calcium, magnesium and other elements. Restflts： Measured containing 17.96% crude protein, crude fat containing 2. 74%, with 23.26% crude fiber, nitrogen - free extract containing 45. 19%, accounting for 5.25% ash. Conclusions： Pennisetum have high nutrient content, so it＇s valuable in use as feed. |
