Determining rumen degradable protein requirements in growing beef cattle
… Specifically, supplying the correct amount of protein to livestock is critically important as it is usually the most expensive macronutrient. Accordingly, the objective of livestock nutrition models should be to describe individual nutrient requirements for an animal and potential ingredients …

Prediction of optimal rumen degradable protein levels in no-roughage, corn-based feedlot diets
… no-roughage, corn-based feedlot diets for rumen degradable protein inclusion is essential in the feedlot setting. Five crossbred steers were fitted with ruminal and duodenal cannulas and used in a 5x5 Latin square design experiment. Dietary treatments were: CON (98% corn; 4.4% RDP), LOW RDP …

Urea-N Recycling in Lactating Dairy Cows
… study was designed to determine the effect of rumen degradable protein (RDP) and rumen undegradable protein (RUP) on urea-N recycling and microbial N flow. Eight mid-lactation Holstein cows were assigned to a repeated 4 x 4 Latin square. The diets were isoenergetic with RDP and RUP …

Partitioning of nitrogen by lactating cows fed diets varying in nonfibrous carbohydrate and rumen undegradable protein
… of dietary nonfibrous carbohydrate (NFC) and rumen undegradable protein (RUP) on metabolic and lactational parameters. Diets were isonitrogenous (17.4% CP) and structured in a 2 x 2 factorial arrangement with levels of NFC at 41 or 47% of dietary OM and RUP at 27 or 41% of dietary CP with …

Interactive Association Between Molecular Structure Spectral Profiles and Nutrient Utilization and Availability of Leaf, Stem, Pods, and Whole Plant Faba Bean Forage in Ruminants Before and After Rumen Incubation
… bean silage as references to study the effect of rumen digestion on the change of its spectral structure and its association to protein and carbohydrate digestion and metabolism characteristics. The faba bean samples used for this research were from three different plots in Yellow Creek, …

Assessing Availability and Utilization of Essential Amino Acids in Dairy Cattle Using Stable Isotope Based Approach
… in ruminant is a big challenge due to the rumen fermentation and complicated post absorption utilization. Current techniques used for direct determination of AA absorption and metabolism are laborious and expensive with large variation. The objectives of this project were to investigate AA …

Effectiveness of canola meal as a source of rumen-undegraded protein for dairy cows
… the remaining "canola meal" (CM), is a rich protein source used as feedstock to different animal species, mainly dairy cows in North America and in Europe. Despite the positive responses in milk production and nitrogen (N) utilization efficiency observed when soybean meal (SBM) is replaced …

Investigation of the Role of Amide I to Amide II Ratio and Alpha Helix to Beta Sheet Ratio of Faba Bean Seeds in the Determination of Microbial Protein Synthesis and Animal Performance and Metabolism in Ruminant Livestock Systems.
… ratio, and α-helix to β-sheet ratio (α_β) on the protein quality (solubility and digestibility), metabolism, and bioavailability in dairy cows has not been established. Thus, the objective of this research was to evaluate the role of the protein-related spectral ratios on the nutrient quality and …

Evaluation of perennial ryegrass cultivars for dairy production under different pasture management
… 1), nutritive value (experiments 1 and 2), rumen degradation (experiment 3), dietary preference (experiment 4) and milk production (experiment 5). Pasture management included growing perennial ryegrass cultivars with and without white clover (Trifolium repens L.) (experiments 1, 2, 3 and 4) …
