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

Influence of Wheat Straw Pelletizing and Inclusion Rate in Dry Rolled or Steam-flaked Corn-based Finishing Diets on Characteristics of Digestion for Feedlot Cattle. [PDF]

, 2016
Eight Holstein steers (216±48 kg body weight) fitted with ruminal and duodenal cannulas were used to evaluate effects of wheat straw processing (ground vs pelleted) at two straw inclusion rates (7% and 14%; dry matter basis) in dry rolled or steam-flaked

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 ...
