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.

Ash-Free Indigestible Acid Detergent Fiber as an Internal Marker to Estimate Digestibility with Grazing Ruminants [PDF]

Journal of Range Management, 1990
Two experiments with wethers and one with steers were conducted to compare extraction methods of ash-free indigestible acid detergent fiber (IADF) from feed, and to determine variation across days in fecal IADF content. In trial I, 4 wethers were fed 4 maturities of intermediate wheatgrass (Agropyron inm (2) pepsin-HCI digestion then a 96hour in vitro ...

Comparison of Ruminal Degradability, Indigestible Neutral Detergent Fiber, and Total-Tract Digestibility of Three Main Crop Straws with Alfalfa Hay and Corn Silage

Animals, 2021
Three main crop straws including corn straw (Zea mays, CS), rice straw (Oryza sativa, RS), and wheat straw (Triticum aestivum, WS), and two forages including alfalfa hay (Medicago sativa, AH) and corn silage (Zea mays, CSil) were analyzed in order to ...

Estimating fecal output and nutrient digestibility using acid detergent insoluble ash as an intrinsic marker in lactating dairy cows: technical note [PDF]

Animal Bioscience
The current study was part of large experiments in a replicated 4×4 Latin square design where 4 dietary treatments (feed supplements) were examined. Fecal samples were obtained from the experiments via total collection (Experiment 1, n = 30; Experiment 2,

Determination and prediction of standardized ileal amino acid digestibility of wheat for pullets during the brooding and growing phases [PDF]

Poultry Science
Wheat serves as a major alternative to corn in layer diets. However, the assessment and predictive models for standardized ileal digestibility of amino acids (SIDAA) from wheat in pullets have not yet been fully established, limiting precision ...
