Transcriptional adaptation of adipose tissue in dairy cows in response to energy overfeeding
… and acute-phase protein. In conclusion, overfeeding energy may increase visceral AT secretion of pro-inflammatory cytokines by stimulating fat accumulation in visceral AT depots. (For the contents in chapter 3 and 4) In experiment 2, mRNA samples of MES and SUBQ collected from a subset of …

The effect of overfeeding and obesity on canine adipose tissue and skeletal muscle transcriptomes
Overweight dogs have a reduced life expectancy and increased risk of chronic disease. During obesity development, adipose tissue undergoes major expansion and remodeling, but the biological processes involved are not well understood. The objective of study 1 was to analyze global gene expression …

Inactivity and overfeeding related changes in skeletal muscle composition and metabolism in captive felids - are they at risk of developing metabolic syndrome?
Obesity and physical inactivity are established key risk factors in the development of skeletal muscle insulin-resistance and type II diabetes in human and domestic animal populations. Wild animals are similarly exposed to these risk factors as a result of captivity. This study aimed at describing …

Rehabilitation of obesity
… interact to cause obesity. Heredity factors, overfeeding in infancy and childhood, repeated dieting, inactivity, lifestyle and psychosocial conditions all contribute to the incidence of obesity.

The role of adipose tissue in the pathogenesis of non-alcoholic steatohepatitis
… inflammation and dysfunction. In response to overfeeding, some individuals develop healthy obesity and are resistant to obesity-associated metabolic diseases; whereas others readily develop one or more of these disorders. The reasons for such disparity in responses to overfeeding are unclear. …

Low-Protein Meal Challenge as a Predictor for Weight Loss Success in Severe Obesity
… respectively, rely on prolonged fasting and overfeeding using whole-room calorimetry assessments, which represents a substantial barrier to the prospective implementation in routine obesity care. To establish a clinically applicable method for specific metabolic phenotyping, the conducted …

Nutritional modulation of the transcriptome in adipose, liver, and polymorphonuclear leukocytes in peripartal dairy cows
… receptors (GPCRs), and 2) evaluate the effect of overfeeding during the dry period on the PMNL transcriptome. In the first study, cows were either 1) retrospectively classified as having high (HI; BCS > 3.75) or low (LO; BCS < 3.25) BCS at -3 wk from parturition, or 2) assigned to a control (CON) …

Genetic analyses of food consumption in growth selected lines of chickens \
… the crop of chicks from the high-weight line via overfeeding was similar to their ad libitum intake. Chicks from the low-weight line could be overfed at earlier ages and to a greater degree than either high-weight or cross chicks. The degree of overfeeding was associated with the relative size of …

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation
… et al., 2005). Our general hypothesis was that overfeeding dietary energy during the dry period, accompanied by the metabolic challenges associated with the onset of lactation would render the cow’s immune function less responsive early postpartum. The chapters in this dissertation evaluated …

Diet-induced thermogenesis in the domestic chicken
… more severe in the LN chicks than in the HNs. Overfeeding of a complete diet increased body weight, the deposition of all carcass constituents, and energetic efficiency. Feed restriction exerted an opposite effect, with the LN chicks exhibiting more pronounced responses than the HNs. Determined …

Characterizing Thiamine Status and Mechanisms of Thiamine Supplementation on Subacute Ruminal Acidosis Attenuation in Dairy Cows
… in today’s intensive management farms. However, overfeeding high grain diets increases the risk of subacute ruminal acidosis (SARA), which is characterized by prolonged decrease in rumen pH and high levels of lipopolysaccharide (LPS). SARA challenge has been confirmed to severely impair animal …

Improving the Efficiency of Dairy Cattle Feeding
… in quantities that likely exceed requirements. Overfeeding of AA results in increased expenses for producers and increased N excretion to the environment, providing economic and environmental incentives to increase N-efficiency. Work presented in the following chapters evaluated the impact of AA …

Equine obesity and its role in insulin resistance, inflammation and risk for laminitis
… of obesity in 13 Arabian geldings by 4 months of overfeeding resulted in compensated insulin resistance (minimal model analysis) with hyperinsulinemia and hyperleptinemia. Although lipid concentrations (nonesterified fatty acids and triglyceride) decreased on a high concentrate diet, they did not …

Phosphorus excretion in beef steers as impacted by increasing levels of corn gluten feed
Overfeeding of phosphorus (P) is a contributing factor to P levels in surface waters. The objective of this study was to determine the impact of increasing levels of corn gluten feed (CGF) as a supplemental source of P on fecal P excretions. Eight Hereford steers (427±79 kg) were randomly assigned …

Bacterial Kidney Disease and Its effect on the Salmonid Immune response

Feeding Strategies Based on Probing Control for E. coli and V. cholerae Cultivations
… should be designed to avoid starvation and overfeeding. This is not an easy task as on-line measurements of key variables are normally not available. A probing feeding strategy using the measurements of the standard dissolved oxygen sensor is developed by M. Åkesson. The key idea is to …

Impact of Precision Feeding Strategies on Whole Farm Nutrient Balance and Feeding Management
… ± 163 kg/d. This corresponded to average daily overfeeding of CP and P of 17.6 ± 17 and 0.4 ± 0.3 kg/d, respectively. Feeding deviation did not differ between feeders. Milk production was negatively associated with kg total deviation and kg CP deviation, but positively related to P deviation. …

MEALS OF DIFFERING CALORIC CONTENT DO NOT ALTER PHYSICAL ACTIVITY BEHAVIOR DURING A SUBSEQUENT SIMULATED RECESS PERIOD IN CHILDREN
… animals has demonstrated that chronic and acute overfeeding can alter physical activity behavior. However, there are no assessments of the acute effects of high-fat/high-calorie meals on physical activity behavior in school-aged children. This is of importance as a typical school lunch is both …
