Effect of diet composition and incubation time on feed indigestible neutral detergent fiber concentration in dairy cows [PDF]

Journal of Dairy Science, 2013
Indigestible neutral detergent fiber (NDF) predicts forage digestibility accurately and precisely when determined by a 288-h ruminal in situ incubation, and it is an important parameter in mechanistic rumen models. The long incubation time required is a disadvantage. Further, intrinsic cell wall characteristics of feeds should be determined under ideal

Comparison of in situ versus in vitro methods of fiber digestion at 120 and 288 hours to quantify the indigestible neutral detergent fiber fraction of corn silage samples [PDF]

Journal of Dairy Science, 2016
Ruminal digestion of neutral detergent fiber (NDF) is affected in part by the proportion of NDF that is indigestible (iNDF), and the rate at which the potentially digestible NDF (pdNDF) is digested. Indigestible NDF in forages is commonly determined as the NDF residue remaining after long-term in situ or in vitro incubations.

Short communication: Evaluation of acid-insoluble ash and indigestible neutral detergent fiber as total-tract digestibility markers in dairy cows fed corn silage-based diets [PDF]

Journal of Dairy Science, 2013
The objective of this experiment was to evaluate acid-insoluble ash (AIA) and indigestible NDF (iNDF) as intrinsic digestibility markers in comparison with total fecal collection (TC) in dairy cows fed corn silage- and alfalfa haylage-based diets. The experiment was part of a larger experiment, which involved 8 Holstein cows [102±28.4 d in milk, 26.4±0.

Hot topic: Apparent total-tract nutrient digestibilities measured commercially using 120-hour in vitro indigestible neutral detergent fiber as a marker are related to commercial dairy cattle performance [PDF]

Journal of Dairy Science, 2012
Measuring individual feed nutrient concentration is common practice for field dairy nutritionists. However, accurately measuring nutrient digestibility and using digestion values in total digestible nutrients models is more challenging. Our objective was to determine if in vivo apparent total-tract nutrient digestibility measured with a practical ...

Comparison of two in situ reference methods to estimate indigestible NDF by near infrared reflectance spectroscopy in alfalfa

Heliyon, 2021
Undigested forage neutral detergent fiber (uNDF) from long-term ruminal in situ incubations are used to estimate indigestible neutral detergent fiber (iNDF).

Nutritional and morpho-anatomical characterization of Phyllostachys aurea (Poaceae, Bambusoideae, Bambuseae) foliage for Argentine livestock systems

Revista de la Facultad de Ciencias Agrarias
Bamboo cultivation in Argentina could represent a major economic activity if its various applications were revealed. This study characterized the anatomy and micromorphology of leaf blades by optical and scanning electron microscopes.

In situ estimation of indigestible compounds contents in cattle feed and feces using bags made from different textiles Estimação in situ dos componentes indigestíveis em alimentos e fezes de bovinos com sacos de diferentes tecidos

Revista Brasileira de Zootecnia, 2011
The objective of this experiment was to evaluate estimates of concentration of indigestible dry matter (iDM), indigestible neutral detergent fiber (iNDF) and indigestible acid detergent fiber (iADF) in samples of cattle feed and feces processed at ...

Effects of neutral detergent fiber digestibility estimation method on calculated energy concentration of canola meals from twelve Canadian processing plants.

Journal of Animal Science, 2021
Our aim was to determine whether the method used to estimate truly digestible neutral detergent fiber (tdNDF) affects calculated concentrations of total digestible nutrients (TDN1x) and net energy of lactation (NEL3x) of canola meal (CM).

Assessment of indicators and collection methodology to estimate nutrient digestibility in buffaloes

Revista Brasileira de Zootecnia, 2011
Dry fecal matter production was estimated from neutral detergent indicators on indigestible fiber, indigestible acid detergent fiber, indigestible dry matter, incubated for 144 hours and 288 hours, as well as chromium oxide (Cr2O3) and enriched and ...
