Free-range production system is increasingly being used in poultry breeding and feed production in many countries. The objective of the current experiment was to evaluate the effects of different raising systems on fat-related traits and mRNA levels of liver lipogenesis genes in Erlang Mountainous chicken. Each of 10 birds (91 day old) from caged, indoor-floor housed, and free-range housing sys...

Zinc α2-glycoprotein (ZAG) has been implicated in fatty acid metabolism and utilization is lower obese higher cachexic adults compared to those of normal weight. Previous studies suggest that ZAG binds the beta3-adrenergic receptor (β3AR) influence adipose tissue by regulating hormone sensitive lipase (HSL). The purpose this study investigate effects a six-month weight loss (WL) or aerobic exer...

OBJECTIVE This study aimed to develop and validate equations to estimate body fat based on anthropometric measurements of subcutaneous fat thickness (SFT) and muscle thickness (MT) measured by A-mode ultrasound (BodyMetrix) in Brazilian adults. METHODS Individuals (n = 206) underwent air-displacement plethysmography for body composition assessment. Arm, thigh, and calf circumferences were als...

An experiment was conducted to investigate the effects of dihydropyridine supplementation on growth performance and lipid metabolism of broilers. A total of 480 one-day-old female Arbor Acres broiler chicks were randomly divided into four groups, each group had six replications of 20 birds. Each group was fed a maize-soybean meal diet supplemented with 0, 100, 200, 300 mg/kg dihydropyridine, re...

BACKGROUND Although smokers tend to have a lower body-mass index than non-smokers, smoking may favour abdominal body fat accumulation. To our knowledge, no population-based studies have assessed the relationship between smoking and body fat composition. We assessed the association between cigarette smoking and waist circumference, body fat, and body-mass index. METHODS Height, weight, and wai...

objective: nowadays the value of bioelectrical impedance analysis (bia) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. the current study determine accuracy of bia compared with body mass index (bmi) measurement for estimating body composition in a group of normal weight employee women with a sedenta...

OBJECTIVE To verify the prevalence of metabolic syndrome and insulin resistance in obese adolescents and its relationship with different body composition indicators. METHODS A cross-sectional study comprising 79 adolescents aged ten to 18 years old. The assessed body composition indicators were: body mass index (BMI), body fat percentage, abdominal circumference, and subcutaneous fat. The met...

The effect of divergent selection for high (H) or low (L) body weight at eight weeks of age for 25 generations on growth and carcass traits between 42 and 58 days of age was studied. The chicks were reared in individual cages under standard management conditions. Selection for low 8-week body weight has resulted in higher relative body weight increase for the period from 42 to 58 days of age co...

BACKGROUND Regional differences in meal fat storage may explain the preservation of fat accumulation in obese persons. OBJECTIVE The objective was to determine whether meal fatty acid (FA) metabolism differs by sex and obesity phenotypes before and after weight loss. DESIGN A [(3)H]triolein-containing meal was given to trace meal FA oxidation ((3)H(2)O generation) and adipose tissue uptake ...
