USING THE PLASMA FREE AMINO ACID DOSE RESPONSE METHOD TO DETERMINE METABOLIZABLE PROTEIN CONCENTRATIONS OF LYSINE AND METHIONINE IN RUMEN PROTECTED SUPPLEMENTS
… days in milk, milk yield, milk true protein concentration and yield, and dry matter intake, indicated the factor that most affected the magnitude of the slope, and hence the technique’s precision, was the difference between plasma Lys concentration of basal and highest infusion …

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
… 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, Saskatchewan with 97 days maturity (late pod stage) and the variety used was CDC …

Nutritional Strategies for Optimizing Nitrogen Utilization by Dairy Cows
… conducted to test the hypothesis that the crude protein (CP) content of the diet can be decreased to improve the efficiency of N utilization for milk production without compromising the supply of metabolizable protein and the lactational performance of dairy cows. Results from the meta-analysis …

EFFECT OF GENOTYPES, TANNIN LEVEL AND PROCESSING METHODS ON THE PHYSICOCHEMICAL, NUTRITIONAL AND STRUCTURAL CHARACTERISTICS OF FABA BEAN GROWN IN WESTERN CANADA
… bean grown in western Canada as an alternative protein and energy source for ruminants. The faba bean used for this research were grown in three different locations in Saskatchewan and included three low tannin types: Snowbird, CDC Snowdrop, CDC 219_16 and five normal tannin types: CDC Fatima, …

IN-DEPTH STUDY OF THE RELATIONSHIP BETWEEN PROTEIN MOLECULAR STRUCTURE AND THE DIGESTIVE CHARACTERISTICS OF THE PROTEINS IN DRIED DISTILLERS GRAINS WITH SOLUBLES
… and triticale DDGS in terms of chemical profile, protein and carbohydrate subfractions partitioned using the Cornell Net Carbohydrate and Protein System and energy values calculated according to NRC (2001), to evaluate the digestive characteristics of the proteins in triticale and triticale DDGS …

Effects of Prepartum Energy and Protein Density on Productivity and Influence of Dietary Iron on Copper Status of Holstein and Jersey Cattle
… yield increased linearly with energy density and protein yield did not differ. Increasing prepartum diet energy density increased yield of milk and 4% FCM. In experiment 2, 26 multiparous and 18 primiparous Jerseys were assigned to one of two CP and rumen undegradable protein (RUP) concentrations …

Improving nitrogen efficiency and profitability of dairy cattle in the United States
… of lower CP diets was the cost per unit of metabolizable protein (MP). In the second study, three treatments were fed to lactating Holstein cows (n = 48) to test proof of concept of NASEM 2021 and a nonlinear optimizer: a control balanced to fulfill all nutrient needs of lactating dairy cows …

Effects of reduced dietary protein and supplemented rumen protected amino acids on the nitrogen efficiency of dairy cows
… 25-30% of dietary N is used for milk protein while the remaining N is lost to the environment. According to National Research Council (NRC, 2001) recommendations, dairy cow rations are formulated in terms of metabolizable protein (MP) which often causes many amino acids (AA) to be fed …

Use of Newly Developed Blended Feed Supplement on Rumen Parameters and Milk Fat in Dairy Cows
… ruminal fermentation, nutrient digestibility, protein-energy synchronization, and its impact on milk production and nitrogen utilization, with the aim of finding an alternative inexpensive supplement source for dairy cows instead of bypass fats and proteins. BFS was compared with conventional …

Influence of Maternal Protein Restriction in Primiparous Heifers During Mid- And/Or Late Gestation on Dam Performance and Progeny Growth, Carcass Characteristics, and Gene Expression
<p>Effect of nutrient status in gestating beef cows has been shown to impact dam performance and may affect developmental processes in the fetus that could influence offspring throughout their lives. One hundred eight Angus × Simmental heifers were utilized in a randomized complete block design …

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 …

Optimizing Feeding Efficiency in Dairy Cows Using a Precision Feeding System
… latter aimed to investigate individual milk true protein production responses of dairy cows to varying levels of metabolizable protein (MP) and rumen-protected amino acids (RPAA) using automatic feeding systems and rank animals based on their individual gross milk protein efficiencies. Results …

Effect of rumen-protected methionine on placenta metabolism, animal performance, and immune-metabolism of dairy cows during the periparturient and early lactation periods
… that the ratio of lysine to methionine in the metabolizable protein was close to 2.8:1. Compared with control, during the fresh period (1-30 days in milk) MET increased intake by 1.7 kg/d, milk yield by 4.1 kg/d, fat yield by 0.17 kg/d, and milk protein yield by 0.20 kg/d. During the …

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 …

Nitrogen Efficiency and Regulation of Protein Synthesis in Lactating Dairy Cows
… environment and 30% or less is retained in milk protein. Plasma amino acids (AA) that are not used for protein synthesis in mammary glands (MG) are catabolized in post splanchnic tissues (liver plus gastrointestinal tract, pancreas, spleen, portal system, and associated adipose tissue) and two …
