Dietary energy utilization in swine
Of the available dietary energy systems, the net energy system provides a more accurate estimate of dietary energy compared to digestible and metabolizable energy systems although net energy values of ingredients and diets are affected by several factors including nutrient composition of basal …

Dietary Energy Restriction During Late Gestation in Multiparous Holstein Cows
… of nutrition. Cows fed FOCA or FOHR had a better energy status during the first 10 DIM. Far-off and close-up diets had minimal effect on metabolism and milk yield during the first 56 DIM.

Regulation of beef heifer productivity by dietary energy and prepubertal administration of bovine somatotropin
Weanling heifer calves (n = 452) grazed tall fescue pastures and were fed a high (H) or low (L) amount of corn supplement during a postweaning treatment period of 136 d. Postweaning gain of heifers receiving L and H was.43 and.62 kg/d, respectively. Heifers receiving H were heavier, and had more …

Transcriptomic and metagenomic impacts of dietary energy of milk replacer in pre-weaned Holstein heifers
… of this study was to examine how an increase in dietary energy in milk replacer of pre-weaned Holstein heifers impacts the microbial profile of the rumen as well as the transcriptome in tissues related to growth and metabolism. Our hypothesis was that pre-weaned Holstein heifers on milk replacer …

Targeting Akt/Mtor Signaling Pathways During Murine Skin Tumor Promotion and The Impact of Dietary Energy Balance Manipulation
… many types of cancer. In contrast, reduction in energy consumption via calorie restriction (CR) has been shown to be a potent inhibitor of carcinogenesis across a broad range of species and tumor types. Previous data has demonstrated differential signaling through Akt and mTOR via the IGF-1R and …

Effects of close-up dietary energy strategy and prepartal dietary monensin on production and metabolism in Holstein cows
… monensin (M) in a single group diet (controlled energy-high fiber, CE) and a two-group diet (CE during the far-off and a high energy diet during close-up, CU) during the dry period (DP) on production and metabolism in the first 84 days postpartum. The CE diet was formulated for a dietary energy …

Effects of prepartum dietary energy and lipid supplementation on hepatic transcriptome profiles in dairy cows during the transition period
… control (CON; NEL = 1.34 Mcal/kg DM) or moderate-energy (OVE; NEL = 1.62 Mcal/kg DM) diet during the entire dry period. All cows were fed a common lactation diet (NEL = 1.69 Mcal/kg DM) postcalving. Percutaneous liver biopsies were collected at -14, 7, 14, and 30 days relative to parturition (DIM) …

Effects of close-up dietary energy content and rumen-protected lysine and methionine fed pre – and postpartum on performance and health of Holstein cows
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

Effects of close-up dietary energy strategy and prepartal dietary monensin on hepatic mRNA expression of enzymes involved in glucose and lipid metabolism in transition cows
… of two different diets: one-stage controlled-energy high fiber diet (CON) fed throughout the entire dry period versus a two-stage diet (OVER) with controlled-energy in far-off period followed by higher energy in close-up period; and 2) to evaluate the effect of monensin (M) supplementation to …

Glucose disposal and insulin sensitivity at rest and during exercise in trained horses adapted to different dietary energy sources and in association with laminitis in ponies
Glucose is a fundamental energy source, the utilization and regulation of which impacts exercise performance and health. These studies have used modeling techniques to evaluate glucose kinetics and dynamics in equids and developed tests to evaluate the status of glucose metabolism. In Part I, 12 …

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation
… not entirely clear (Goff, 2006). The negative energy balance associated with parturition leads to extensive mobilization of fatty acids stored in adipose tissue, thus, causing marked elevations in blood non-esterified fatty acids (NEFA) and B-hydroxybutyrate (BHBA) concentrations (Drackley et …

Management and Nutritional Approaches to Reducing Glycolytic Potential and Stress Responses in Pigs
… was conducted to investigate the effects of dietary energy source (control vs. low carbohydrate vs. high fat vs. high fat-low carbohydrate) and fasting (0 vs. 36 h) on the dynamics of muscle GP and blood acid-base balance in response to handling. Dietary energy source and fasting did not …

A bioenergetic simulation model of orchard populations of the pine vole (Microtus pinetorum)
… functions of bioenerqetic status. Forage gross energy availability, digestibility, palatability, and preference were functions of Julian day. Daily energy budget (DEB) was a function of age, reproductive status, body weight, ambient temperature, and daily activity level. Energy acquisition was …

Studies on the nutrition and metabolism of turbot (Scophthalmus maximus L) with reference to fish farming
… of sprat, as a function of high non-protein energy ratios in sprat. This factor was exploited in the production of a diet containing no fresh fish and which produced superior results to diets containing fresh fish; the optimum level of lipid in the diet was determined as 18%. The study of …

Influence of prepartum nutrition on cow performance and subsequent calf performance, glucose tolerance, carcass characteristics, efficiency, and gene expression
… over the last decade. Because of the elevated energy and CP content of corn coproducts, cow drylot 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, …

Transcriptional adaptation of adipose tissue in dairy cows in response to energy overfeeding
… Holstein dairy cows were fed either moderate energy diet (MoE, NEL = 1.62 Mcal/kg DM) or controlled energy diet (LoE, NEL = 1.35 Mcal/kg DM) for 8 weeks and sacrificed. Compared with LoE animals, MoE cows had markedly increased visceral adipose mass (Nikkhah et al., unpublished data). Higher …
