Fat deposition in relation to sexual maturation of Japanese quail
… mature was associated with a reduction in body fat. The effects of the other treatments on sexual maturity, however, were not consistently associated with differences in body weight and/or body composition. In the second phase of this study, adipocyte hyperplasia was examined in relation to …

Adipocyte hyperplasia and fat deposition in high-weight and low- weight chickens
… overconsumption increased weight gain and fat deposition, with concomitant increases in the total adipocyte DNA content of the assayed fat depots. Injections of DNA-specific [methyl³H] thymidine resulted in higher radioactivity levels in the fat depots of forced versus ad libitum or …

Investigating the Effects of Sodium Benzoate on Fat Deposition, Pharyngeal Pumping, and Related Genetic Mechanisms in Caenorhabditis elegans
… genes of interest dealing with the synthesis of fatty acids, insulin signaling pathway, nuclear hormone receptor, and Krüppel-like zinc finger transcription factors but no significant difference was found in gene expression levels. These results therefore led to the conclusion that sodium …

Characterizing the amount and variability of intramuscular fat deposition of pork loins using barrows and gilts from two sire lines
… 15, 20, and 24 of age to estimate marbling, back fat, and loin depth. Two or four contemporary pigs were scanned at each of these time points and then slaughtered on the following day to validate the ultrasound procedure. All trial pigs were slaughtered at 24 weeks of age, and loins were …

The effects of supplementary threonine and/or choline on enzyme activity and fat deposition in livers of albino rats fed 9% casein diets

Characterising fat tissue structure and function in response to hypoxia in grey seals, an animal model of extreme fat deposition and mobilisation, using novel <i>in vivo</i> and <i>in vitro</i> approaches
… reproduction and moulting. The regulation of fat mobilisation during these processes is a key factor for their survival. Unlike in humans, reproductive fitness and first-year survival are positively linked to adiposity in seals. Therefore, the rapid fluctuations in body mass and metabolic …

Effects of added dietary fat and protein on the growth and carcass characteristics of turkeys
… on the growth, carcass characteristics and fat deposition of the turkey. In the first experiment, 0, 5, 10 or 15% fat from three sources (Fat 1, Fat 2 or Fat 3) was added to low (18%), standard (21%) or high (24%) protein diets fed to Nicholas Large White male turkeys from 8 to 22 weeks of …

Evaluation of lysine and metabolizable energy in diets for broilers
… EM should be used with caution, as it increases fat deposition in the carcass, leading to changes in the serum biochemical profile and in the activity of liver enzymes. While the best ratio to reduce body fat deposition was 5.32 g/Mcal corresponding to the level of 2950 Kcal/kg of EM and 1.57% of …

The gut microbiota as a contributing factor to antipsychotic-induced weight gain and metabolic dysfunction
… including weight gain, insulin resistance, fat deposition, glucose dysregulation and ensuing co-morbidities such as type II diabetes mellitus. The mechanisms underlying these side effects remain to be fully elucidated and adequate interventions are lacking. Further understanding of the …

Creation and characterization of mice with a mutation disrupting binding of a transcriptional repressor of insulin-like growth factor 2
… muscle mass and a 15% decrease in subcutaneous fat deposition despite similar body weights. Though IGF2 is a highly conserved gene across species, similar mutations in IGF2 have not been detected. Therefore, the effect of mutations preventing the binding of ZBED6 to IGF2 in species other than …

The effect of early feed restriction on the performance, organ weights, carcass composition, and lipid and protein metabolism in broiler chickens
… on body weights, feed conversion, organ weights, fat deposition, carcass and muscle composition, plasma lipids, lipogenesis, lipolysis, and muscle tissue DNA and RNA in broiler chickens. In Experiments 1 and 2, broiler chicks were reared in litter pens for 49 days, while Experiments 3,4, and 5 …

Glucose tolerance, plasma insulin, and plasma glucagon in relation to obesity in chickens
… than in the LWs. It was concluded that excessive fat deposition in chickens selected for rapid growth is associated with hyperinsulinemia and insulin resistance.

Effects of gestational heat stress on the lactational performance of gilts and growth performance and carcass characteristics of second-generation offspring
… hyperthermia (gHS) experience greater fat deposition during life and yield carcasses with greater fat:lean content at slaughter compared to pigs gestated under thermoneutral conditions (gTN). The objectives of this study were to 1) determine whether gHS impacts the lactational …

Dietary manipulation causes childhood obesity-like characteristics in pigs
… 0.05) subcutaneous, intramuscular, and perirenal fat deposition, and induced hyperglycemia, hypoinsulinemia, and low-density lipoprotein hypercholesterolemia; however, a 6 wk dietary intervention partially recovered a normal physiology. These data suggest pre-pubertal pigs fed HED are a viable …

Skeletal Muscle and Post-Heparin Plasma Lipoprotein Lipase Activities (Exercise, Triglyceride)
… plasma TG removal and/or changes in TG-derived fatty acid uptake by tissues. This thesis examined the physiological significance of changes in the LPL capacities of skeletal muscles and adipose tissue, and post-heparin plasma (PHP) in rats using experimental conditions of diet and exercise. …

The Use of Albuterol, a Beta-Adrenergic Compound to Alter Fat and Muscle Deposition in Lambs
… discovered which partition nutrients away from fat deposition and increment muscle accretion in poultry, swine, sheep and beef One beta-adrenergic compound ( albuterol) has never been researched on any meat producing animals. Therefore, the objectives of this study were to determine the effect …

Bisphenol A and Obesity
Obesity and excess body fat is generally blamed on low physical activity and pour eating habits. However, there is increasing evidence that environmental chemicals, such as Bisphenol A (BPA), recently linked to altered adipose and glucose metabolism, may be aggravating the problem. Due to chronic …

Lipid metabolism and mitochondrial respiration in adipose tissue and liver during obesity
… is defined as the excessive accumulation of fat, which presents a risk to health, with 26% of adults in the UK classed as obese in 2024. Most fats are stored in white adipose tissue (WAT), which is greatly expanded during obesity, and shows impaired energetic function. In addition, the liver …

Growth, body composition and costs of feeding Holstein heifers
… showed that compensatory gains were mainly fat. Lasalocid feeding increased daily gain and subcutaneous fat deposition but reduced feed intake and ribeye area. When moving grazing heifers to drylot a total mixed ration with fishmeal or soybean meal as protein sources gave similar responses. …
