Abstract

A study was conducted to estimate nutritive value of forage sources used in deer diets. Bags containing feedstuffs were incubated four times for periods up to 72 hours in two chemostats filled with ruminal fluid from deer or cattle. Parameters estimated were water-soluble and $65{\mu}m$ filterable plus insoluble digestible fractions(No. = 4) and extent of disappearance(No. = 8) of feed neutral detergent fiber(NDF). Among tested feeds, the ranking of values of these parameters were soybean hulls > alfalfa pellets > corn cobs or rice straw > cottonseed hulls or rice hulls > sawdust, indicating that soybean hulls and alfalfa pellets were more fermentable than other agricultural residues. It is possible to utilize variability among tested feeds of fraction, disappearance rate and (or) extent of DM and NDF when these feeds are used as roughage sources in deer diets.
