Measuring DM and NDF Digestibility and Defining Their Importance

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

In Vitro and In Situ Techniques for Estimating Digestibility - Digital CSIC

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

A comparison between in vitro digestibility in situ

digestibility of grass and maize silages The strength of the CP-based relationships may be ascribed to the wide range in CP contents resulting from the application of urea to some forages The in vitro digestibility-based relationships were poorer than for grass and maize silages (Givens et al 1989 and 1995)

Determining the preference in vitro digestibility in situ

A preliminary in vitro digestibility experiment was conducted to determine the DM digestibility of algae meal (Table 1) compared with hay and soyhulls Three cannulated beef steers (998 ± 103 kg) were tran-sitioned to a concentrate-based diet through a series of 4 step-up diets where corn gradually replaced hay

Forage NDF digestibility can be measured in one of two ways In situ NDF digestibility With the in situ method forages are placed in small dacron bags and then inserted into the rumen of a cow through a ruminal cannula The amount of NDF prior to ruminal incubation is compared to the amount of NDF remaining after ruminal incubation

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.

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).

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.

Why is digestibility important?

• Digestibility is important because feces represent the greatest loss of ingested energy – Feces = 20-50% loss of energy (DE) – Gasses + Urine = 15-25% loss of energy (ME) – Heat = 5-15% loss of energy (NE) • Uses (value) of measuring digestibility
