In individual, single-phase feeding animals were fed extensively (group E--7 animals) or intensively (group I--7 animals) in semi ad libitum system. The mixtures differed in composition as well as energy and nutritional value, with constant ratio of protein to energy of 13.12:1 in intensive feeding and 13.04:1 in extensive feeding. Fibre content per 1 kg mixture was 3.43% in group I and 12.3% i...

Objective:  Anchomanes difformis is a member of the plant family Araceae which is used as a diuretic but also has other medicinal applications. This study investigates the dietary effects of A. difformis on the kidneys of adult wistar rats. Materials and Methods: Sixteen rats were used and were weighed, before and after the experiment. All rats were randomly divided into four groups. All groups...

The effects of acute and repeated intraparaventricular (iPVN) administration of human relaxin-3 (H3) were examined on food intake, energy expenditure, and the hypothalamo-pituitary thyroid axis in male Wistar rats. An acute high dose iPVN injection of H3 significantly increased food intake 1 h post-administration [0.4+/-0.1 g (vehicle) vs 1.6+/-0.5 g (180 pmol H3), 2.4+/-0.5 g (540 pmol H3) and...

BACKGROUND Alzheimer's disease (AD) is a progressive neurodegenerative disorder that primarily strikes the elderly. Studies in both humans and animal models have linked the consumption of cholesterol and saturated fats with amyloid-beta (Abeta) deposition and development of AD. Yet, these studies did not examine high fat diets in combination with reduced carbohydrate intake. Here we tested the ...

Compensatory growth is an integral part ofNew Zealand beef production systems (Nicol and Kitessa, 1997) with restricted winter nutrition followed by good spring and summer feeding enabling a better fit with seasonal pasture production. Purchasers of store cattle (including feedlotters) often prefer animals with a previous history of perturbed growth because they believe they can benefit from hi...

BACKGROUND/AIMS Antagonism of the endocannabinoid receptor-1 (CB1R) directly improves whole-body metabolic parameters of insulin resistance. The present investigation determined the effects of chronic CB1R antagonism on whole-body and skeletal-muscle insulin action in insulin-sensitive lean and insulin-resistant obese Zucker rats. METHODS Animals were either fed ad libitum or in pairs, or tre...

The objective of this study was to evaluate the effects ginger as an additive in diet fattening rabbits. Sixty weaned rabbits (35 days old) were randomly assigned four groups (n = 15). Animals fed ad libitum with a control or one three experimental diets supplemented 0.5, 1, and 2 g per 100 feed during 28 d. Weight gain final week experiment significantly [...]

Lipogenic and lipolytic capacities were measured in subcutaneous (backfat) and omental adipose tissue of beef steers weighing 113, 231, 363 and 505 kilograms. A comparison also was made between ad libitum-fed and restricted-fed steers during fattening. Maximum lipogenic capacity in both adipose sites of the ad libitum-fed animals was with the 363-kg steers, and the minimum with the 505-kg steer...

Tumor promotion associated with increased dietary fat may be inhib ited by reduction in total caloric intake. This hypothesis was tested in rats given either 7,12-dimethylbenz(fl)anthracene to induce mammary tumors or 1,2-dimethylhydrazine to induce colon tumors. One week after dosage with either carcinogen, the rats were fed semipurified diets that provided 4% fat with ad libitum calories or 1...
