Forages for cattle : new methods of determining energy content and evaluating heat damage (1993) [PDF]

, 1993
The crude fiber method of feed analysis has been used for more than 100 years. Although this method was an important first attempt at determining the energy content of feeds, it has a number of shortcomings.

Validação de equações preditivas da fração indigestível da fibra em detergente neutro em gramíneas tropicais Validation of predictive equations for neutral detergent fiber indigestible fraction in tropical grasses

Revista Brasileira de Zootecnia, 2004
Objetivou-se neste trabalho validar as equações de predição da fração indigestível da fibra em detergente neutro (FDNi) adotadas pelos sistemas nutricionais Cornell Net Carbohydrate and Protein System (equação de Sniffen) e National Research Council (equação de Conrad) em gramíneas tropicais. Para tal, construiu-se um banco de dados constituído por 114

Indigestible neutral detergent fibers: Relationship between forage fragility and neutral detergent fibers digestibility in total mixed ration and some feedstuffs in dairy cattle.

Veterinary research forum : an international quarterly journal
Indigestible neutral detergent fibers (iNDF) accurately predict forage digestibility when measured in situ. The objective of this study was to determine the effects of rumen incubation times on the estimated concentrations of iNDF for four forages (alfalfa hay, corn silage, wheat straw and orchard grass), four concentrates (barley grain, soybean meal ...

Corn Grain and Liquid Feed as Non-Fiber Carbohydrate Sources in Diets for Lactating Dairy Cows: Digestibility Trial [PDF]

, 2010
We predicted that adding a sugar-based liquid feed (LF) additive would improve the non-structural carbohydrate (NSC) digestibility of corn grain ground coarsely compared to finely ground corn.
