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 …

Improving the Efficiency of Dairy Cattle Feeding
… in models that predict nutrient supply and requirements of dairy cows result in inefficient feeding, as under-prediction of requirements results in deficiency, and over-prediction results in excess. To avoid limitations in production due to AA deficiencies, protein is fed in quantities that …

The effect of varying levels of dietary protein on carcass composition of eleven- and eighteen-month-old male rats
… months, in response to varying levels of dietary protein was determined. Groups varying of ten rats of each age were fed diets containing from 1.53 to 8.05 percent protein as casein supplemented with d-1-methionine for five weeks. The 8.05% protein groups were used as controls. Carcasses were …

Analysis of the ammonium assimilation pathways of the human colonic bacterium, bacteroides thetaiotaomicron
… ammonium accounts for up to 70% of the microbial protein production, which satisfies up to 85% of the host protein requirements. Similar numbers for the human colon have not been determined. However, colonic bacteria are responsible for the production of ammonium, derived from host-secreted urea …

Appetite, oral frailty, and nutritional status of nursing home residents: Descriptive cross-sectional study
… status by Mini Nutritional Assessment (MNA). Protein and energy intake were estimated from a seven-day nursing home menu and compared with the estimated individual energy and protein needs. Results: Approximately 77% of participants were at a healthy weight or BMI > 23 kg/m². The prevalence of …

The effects of forest thinning on the food-based carrying capacity of a mixed oak forest for white-tailed deer in the ridge and valley province of Virginia
… of Virginia to provide the seasonal digestible protein and energy requirements of a white-tailed doe following a commercial thinning operation was evaluated. The element of time elapsed since thinning was emphasized and was represented by three contiguous forested parcels thinned over 3 …

Protein Utilization and Requirements in Broiler Breeders
… to curb excessive body weight gain, both the protein requirements and feeding strategies of broiler breeders are being revisited. A series of studies were conducted to determine the protein and amino acid requirements of broiler breeders during the production phase and to determine the …

Biological variation in basal metabolic rate and energy metabolism
… (1985) in a report entitled EllerK}' and Protein Requirements. Since its publication, serious concern has been expressed on the validity of these equations, largely because the analysis appears to be based on a biased and incomplete analysis of the world literature on BMR. Using an …

Investigating the habitat selection and dietary preferences of a largely sedentary population of blue wildebeest in the Kgalagadi Transfrontier Park – impacts of permanent surface water provision in a semi-arid environment
… plants allow the animals to maintain their crude protein requirements throughout the dry season, despite a pronounced drop in the quality of available graze during this period. These results suggest that wildebeest were not food limited during the study period, although the distribution of these …

Optimisation of quality and nutritional value of reformed/restructured meat products for older adults developed using plant proteins
… potential uses of plant-derived ingredients [pea protein isolate (PPI), rice protein (RP) and lentil flour (LF)] in a meat model using underutilised beef cuts. The meat model could then be extrapolated to a meat product such as beef patties and restructured beef products. The physicochemical …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… focused on formulating diets to address nutrient requirements of cattle for given level of animal performance. While predictive models account for many factors that may affect nutrient requirements, additional physiological effects can alter the animal's ability to utilize dietary nutrients. …

Influence of prepartum nutrition on cow performance and subsequent calf performance, glucose tolerance, carcass characteristics, efficiency, and gene expression
… rations may easily exceed cow energy and CP requirements. The effects of excessive prepartum dietary energy and CP intake of subsequent progeny needs to be further investigated. In one experiment, spring-calving, mature cows and their progeny were used to evaluate the effects of prepartum …

Dietary patterns for population and planetary health: opportunities and challenges for older adults
… overall percentage of individuals not meeting protein requirements was low, this proportion increased at higher assessed values, especially among males. The environmental impacts of dietary patterns were assessed, reflecting existing cultural eating habits. The synthesis of the evidence from …

Physiological studies of whey protein in older people, with a focus on feeding behaviour, nutrition, obesity, type 2 diabetes mellitus and post-prandial blood pressure
… effects of under-nutrition, reduced dietary protein intake, anabolic resistance to dietary protein (the need for greater intakes to produce the same benefits, particular on muscle mass and function) and consequent muscle loss, reduced function, and in some cases the development of …
