Intake, Digestibility, Nitrogen Balance, Rumen, and Blood Parameters of Cattle Supplemented With Acacia mearnsii Extract

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT This study aimed to evaluate the effect of increasing levels of Acacia mearnsii extract as a source of condensed tannins on feed intake, nutrient digestibility, nitrogen (N) balance, rumen fermentation, and blood parameters of feedlot‐finished cattle. Eight rumen‐cannulated bulls were distributed in a replicated 4 × 4 square Latin design.

Species‐level exploration of the gut microbiome in the leaf‐eating Presbytis monkeys reflected the effects of anthropogenic activity and specialized dietary niches: Conservation on the fourth biodiversity level

iMetaOmics, Volume 2, Issue 4, December 2025.
This study integrates full‐length 16S rRNA and deep metagenomic sequencing to explore species‐level gut microbial composition and function in two endangered leaf‐eating langur species—white‐headed langurs and François' langurs—across gradients of human disturbance.

Indigestible cellulose and lignin in determining feces production and apparent digestibility in horses - doi: 10.4025/actascianimsci.v34i3.10577

Acta Scientiarum: Animal Sciences, 2012
Four crossbred geldings were used in a randomized blocks experimental design. The objective was to study the use of the internal markers indigestible cellulose (iCEL) and indigestible lignin (iLIG), obtained in situ (cattle) or in vivo (equine) to ...

Impacts of Municipal Treated Wastewater on Growth Performance and Nutritional Composition of Barley (Hordeum vulgare L.) Under Arid Regions Conditions

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Barley (Hordeum vulgare L.) is considered one of the most valuable cereal crops worldwide, ranking fourth in production and providing high‐quality forage for ruminant animals. Conventional forage cultivation is unsustainable in arid and semi‐arid regions, where water scarcity and an extreme arid climate prevail, because of the high water ...

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 ...

Chemical composition and ruminal degradability of tucumã (Astrocaryum aculeatum Meyer) peel as a by-product in ruminant feeding [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
This study evaluated the chemical composition and ruminal degradability of tucumã peel (Astrocaryum aculeatum), aiming at its use in ruminant feeding. Bromatological analyses revealed a high content of neutral detergent fiber (70.4%) and ether extract ...
