Predicting nutrient values of elephant grass (Pennisetum purpureum) using near infrared reflectance spectroscopy (NIRS) at Disney’s Animal Kingdom

From May to December each year, the African elephants (Loxodonta africana africana) at Disney’s Animal Kingdom receive elephant grass (Pennisetum purpureum) as a significant portion of their diet. Near infra-red reflectance spectroscopy (NIRS) is used to quickly predict the nutrient quality of the forage. Samples of elephant grass have been collected since 2003 and used to develop calibration equations. As...

Chemical analysis of elephant grass (Pennisetum purpureum) using near infrared reflectance spectroscopy (NIR)

Samples of Pennisetum purpureum (PP) were collected weekly commencing the summer of 2002 and throughout the year 2003. This grass is used in the feeding enrichment program for the African elephants (Loxodonta africana) at Disney’s Animal Kingdom (DAK). Samples were submitted to a laboratory where analyses of moisture, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), fat...
