Improving nitrogen efficiency and profitability of dairy cattle in the United States
… of these studies were to assess U.S. dairy nutritionists' approaches toward balancing CP in lactating cow diets, and to leverage existing knowledge of postabsorptive AA metabolism through the application of a mathematical ration-balancing model to predict N efficiency through a more accurate …

Predicting post-absorptive amino acid supply to the mammary tissue
… data prevents their incorporation into current models. A greater supply of AA to the mammary glands does not always mirror AA absorption—the process by which absorbed AA convert into milk protein is variable, and this may be linked to the way the udder regulates AA uptake to preserve …

Nutritional and genetic characterization of dairy cows managed on pasture-based systems, identifying key aspects to improve their performance
… and British Friesian. Four different genetic models, increasing in complexity (considering breed or strain classification, crossbreeding proportion, and heterosis effects) were tested. Specific effects for some genetic strains, as well as heterosis effects between some strains with Chilean …

Determining rumen degradable protein requirements in growing beef cattle
Nutrition is an essential component of livestock production. Diets need to be formulated to optimize growth and performance,but providing nutrients with cost management in mind is also important. Specifically, supplying the correct amount of protein to livestock is critically important as it is …
