In Situ / In Sacco Digestibility • Is a biological evaluation of a feed • Feed is sealed in a porous bag and suspended in the rumen of fistulated cows • Assume in situ = in vivo – But only measures fermentative digestion • Not adequate for low fiber feeds • Losses from the bag may compensate for the lack of intestinal digestion

digestibility require animals to be surgically modified and measurements of digesta flows and of microbial and endogenous contributions of nutrients may be needed resulting in digestibility and degradability estimates subject to large variability and additional errors associated with use of digesta flow rate markers
The objectives of this study were to determine the chemical composition and dry matter digestibility of Quercus resinosaleaves harvested at different seasons of the year and to assess the
How accurate are in vitro and in situ digestion techniques?
In vitro and in situ techniques are used widely to estimate digestibility and rumendegradability,andtostudyruminal fermentation.Itis difficulttoappraise the accuracy of many of these techniques. Only the in vitro digestibility tech- nique was developed following calibration and validation of the in vitro estima- tions against the in vivo values.
What is the goal of in vitro and in situ methods?
The goal of most in vitro and in situ techniques is to estimate total-tract digestibility or rumen degradability. It is very unlikely that values measured in vitro are identical to the intended in vivo values, and thus mathematical modelling is a useful tool to link the data obtained in vitro or in situ with the processes occurring in vivo.
How do in situ and in vitro gas production profiles compare?
0þ U (4:10) for in vitro gas production profiles. Although ranking of and comparisons between feeds according to their in situ or in vitro E values are similar, the estimates of E values obtained using the in situ technique are numerically greater than those obtained using the in vitro gas production method (Lo´pez et al., 1998, 2000).
How is digestibility estimated in the small intestine?
Methods to Estimate Post-Ruminal Digestibility Some in vitro techniques have been designed to estimate digestibility (mainly of the feed protein) in the small intestine (Calsamiglia et al., 2000). These tech- niques are based on the use of enzymes to simulate abomasal and intestinal digestion (Stern et al., 1997).
