Neuropeptide Y (NPY) was injected directly into the paraventricular nucleus of the hypothalamus (PVN) of satiated, brain-cannulated rats, and food and water intake were measured 0.5, 1, 2, 4, and 22 hr postinjection. NPY (24, 78, 235, 783, and 2351 pmol/0.3 mul) produced a large, dose-dependent increase in food intake as well as small increase in water intake. The latency to eat was about 10 mi...

We examined food intake in chronically maintained decerebrate rats in response to two antimetabolic drugs known to stimulate food intake, 2-mercaptoacetate (MA) and 2-deoxy-D-glucose (2DG). MA reduces fatty acid oxidation, and 2DG reduces glucose utilization. Because previous work has shown that insulin-induced hypoglycemia increases food intake in decerebrate rats, we predicted that 2DG would ...

Food acceptance and toxic effects of feeding sodium selenite (Se) alone and in combination with monosodium glutamate (MSG), a taste enhancer were studied in the laboratory rat. Dose-dependent stimulation of daily food intake was observed with MSG offered in no-choice or bi-choice with the plain food. Consumption of pellets containing 0.05, 0.5 and 1.0% Se was significantly low than the plain or...

Although many studies of Drosophila melanogaster report an effect of diet upon lifespan, it is assumed rather than know that adults maintained on restricted diet acquire fewer nutrients. Diet is restricted in practice by feeding flies a medium where nutrients are diluted and some early reports suggest that flies on diluted medium compensate with increased food intake to consume equal calories o...

There are a range of viewpoints on how best to feed and manage dairy calves early in life. Traditional approaches to rearing dairy calves have focused on stimulating early solid feed intake through restricting intake of milk or milk replacer. A conventional milk feeding rate is approximately 10% of a calf’s birth weight, an amount that translates to between 4 and 5 L/day, supporting under 0.5 k...

This study was conducted to investigate the possible involvement of the histaminergic system in themediation of ghrelin-induced feeding behavior in broiler chickens. In the trial 1, the effect ofintracerebroventricular (ICV) injection of ghrelin on feed intake was examined in 3-h feed-deprived broilerchickens. In the trials 2 and 3, the chickens were received ICV chlorpheniramine (an H1 recepto...

Recent studies suggest that the endocannabinoid system modulates feeding. Despite the existence of central mechanisms for the regulation of food intake by endocannabinoids, evidence indicates that peripheral mechanisms may also exist. To test this hypothesis, we investigated (1) the effects of feeding on intestinal anandamide accumulation; (2) the effects of central (intracerebroventricular) an...

BACKGROUND Research concerning child's food intake have considered various influencing factors, for example parental feeding strategies, demographic and weight factors. At this time, however, there are few findings that explore these factors simultaneously. Accordingly, the aim of this study was to test a structural equation model regarding the associations between maternal feeding strategies a...

We report feeding studies on adult domestic cats designed to disentangle the complex interactions among dietary protein, fat and carbohydrate in the control of intake. Using geometric techniques that combine mixture triangles and intake plots from the geometric framework, we: (1) demonstrate that cats balance their macronutrient intake, (2) estimate the composition of the target balance and (3)...
