Chemical Composition and In Sacco Degradation Kinetics of Four Common Biowastes in Canterbury

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
This research aimed to quantify the chemical composition and rumen degradation kinetics of three local and one imported biowaste using the in sacco nylon bag technique. Triplicate samples of oven‐dried biowastes ground to 4 mm were incubated in the rumens of four cows for 0 h, 2 h, 4 h, 6 h, 12 h, 24 h and 72 h.

Acid Detergent Insoluble Protein as Tropical Forages Rumen Undegradable Protein Estimator Proteína insolúvel em detergente ácido como estimador da fração protéica não degradável no rúmen de forragens tropicais

Revista Brasileira de Saúde e Produção Animal, 2010
The undegradable rumen protein fraction estimated from neutral detergent insoluble nitrogen (NDIN) was studied. A total of 540 samples were used, obtained from manual grazing simulation and esophageal extrusa in elephant grass and mombaça grass, from ...

In vitro evaluation of protein digestibility in the abomasum and small intestine of ruminants

Agricultural and Food Science, 1984
The investigation included studies with microbial protein, 0,5 % formaldehyde (HCHO) treated protein in soybean meal, and ruminally undegradable feed proteins in cotton seed and sunflower seed cakes. Microbial mass was separeted with centrifugations from

Supplementation of Rumen-Undegradable Protein to the Diets of Early Lactation Holstein Cows on Grass Pasture

Journal of Dairy Science, 1998
The objectives were to evaluate supplements differing in rumen-undegradable protein (RUP) on the performance of early lactation cows on grass pasture. Twenty-four Holstein cows averaging 68 d of lactation and 39.8 kg/d of milk were rotationally grazed on predominantly Dactylis glomerata pasture for 8 wk.

Effects of including white clover and plantain species in perennial ryegrass pastures on qualitative indicators and metabolome of milk

International Journal of Dairy Technology, Volume 79, Issue 1, January–March 2026.
Mixed sward pasture systems are being investigated due to their potential to improve bio diversity and sustainability metrics; our study provides a due diligence on the impact of pastures containing perennial ryegrass, white clover and plantain species on the composition and functionality of milk.

Maize Silage Associated With Hay From Xerophytic Plants in Lamb Feeding: Intake, Digestibility, and Economic Feasibility

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT The aim of this study was to evaluate the effect of the partial inclusion of 25% hay from xerophytic plants in maize silage in feedlot lamb in the semiarid region. Non‐defined breed male lambs were used in a completely randomized design, with five experimental units per treatment.

Effects of Rumen-Undegradable Protein on Dairy Cow Performance: A 12-Year Literature Review

Journal of Dairy Science, 1998
In order to integrate and analyze knowledge on the use of protein supplements and protein nutrition of lactating dairy cows, we compiled a review of 108 studies published throughout the world, but principally in the Journal of Dairy Science between 1985 and 1997.
