Development, validation and application of a three-step in vitro procedure for estimating intestinal digestion of protein in ruminants
Keyword(s):
The total amount of dietary protein available for absorption is dependent on the flow of dietary nitrogen (N) to the duodenum and its intestinal digestibility. Variation in intestinal digestion among protein supplements has been reported in vivo (Stern et al., 1985) and in situ (Hvelplund, 1985). Obtaining estimates of protein digestion in the small intestine is expensive, labour intensive and requires the use of surgically prepared animals. The objective of this study was to develop a reliable in vitro technique to estimate intestinal digestion of proteins in ruminants.
