The effect of ractopamine, a phenethanolamine beta-adrenergic agonist, on growth, nutrient utilization and carcass composition was studied in two lines of pigs that were fed high (24%) or low (12%) protein diets. Of the two lines of pigs that had been selected for seven generations for rapid lean growth when fed either the higher (HS line) or low (LS line) protein diet, the HS line tended to ex...

1. Weanling rats were fed on purified-casein diets containing active and inactive (autoclaved) field bean (Vicia faba L.) proteinase inhibitors (PI) at levels of 1.25, 2.5, 5.0 and 10 g/kg. Diets containing raw- and autoclaved-field-bean meal (FBM) were also given. The body-weight gain, protein efficiency ratio (PER); i.e. the ratio of the live weight gain in g/g of protein consumed and apparen...

BACKGROUND A paediatric liver transplant programme was started at the Wits Donald Gordon Medical Centre, Johannesburg, South Africa (SA), in November 2005. We reported on the first 29 patients in 2012. Since then we have performed a further 30 transplants in 28 patients, having met the major challenge of donor shortage by introducing a living related donor programme and increasing the use of sp...

Corn (Zea mays L.) silage (CS) is a nutritious food that can be used as a supplement in dairy cows. The aim of this study was to determine the effect of supplementation with two amounts of CS on milk production and composition, live weight and body condition, as well as on some blood indicators for energy and protein metabolism on dairy cows in early lactation and grazing low mass pasture durin...

T he World Health Organization estimates that by 2015 the number of adults who are overweight (body mass index [BMI], 25.0–29.9 kg/m 2) or obese (BMI ≥30 kg/m 2) will surpass 1.5 billion. 1 Excess body weight is an independent risk factor for mortality. 2 Among the constellation of weight-related comorbidities that bring the greatest burden for obese patients and their healthcare providers are ...

the purpose of the present study was to compare some biochemical markers of cancer diseases risk between two groups of active and inactive postmenopausal women. for this purpose, 74 postmenopausal women were required to complete baecke questionnaire. they were divided into two groups: active (age: 55.89±4.38 years, height: 156.93±0.05 cm, weight: 63.18±6.50 kg, body fat percentage: 26.25±6.29, ...

OBJECTIVE Overweight and obesity are globally increasing risk factors for diseases in the context of metabolic syndrome. A randomized controlled trial was conducted to investigate whether there are any existing differences between two lifestyle intervention strategies with respect to weight reduction after 1 year. SUBJECTS AND METHODS A total of 166 subjects with a body mass index of 28-35 kg...

BACKGROUND It is not clear whether varying the protein-to-carbohydrate ratio of weight-loss diets benefits body composition or metabolism. OBJECTIVE The objective was to compare the effects of 2 weight-loss diets differing in protein-to-carbohydrate ratio on body composition, glucose and lipid metabolism, and markers of bone turnover. DESIGN A parallel design included either a high-protein ...
