A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...

The ability of vitamin A deficient rats to resist infection with P. berghei was investigated. When 10 X 10°erythrocytes bearing the parasite/100 g body weight were given to the vitamin A protein energy undernourished rats, parasitemia developed in these animals at a faster pace than the controls. A high number (60% to 95% ) of red blood cells (RBC) carrying the parasite were noticeable within ...

The immune system protects organisms against infection, but this protection presumably comes at a cost. Here, we asked whether food restriction would compromise the ability of an organism to generate an immune response on reexposure to an antigen, which would represent a functional cost of immunological memory. Immunological memory is generated when B and T lymphocytes sensitive to components o...

The regulation of feeding behavior in adult Drosophila melanogaster includes such elements as ingestion responsiveness, volume ingested in a single meal, food storage in the crop and rate of defecation. Our results suggest that feeding behavior varies in a manner dependent on feeding regime (food-deprived or ad-libitum-fed) and nutritional state. Fed flies that are subsequently food-deprived be...

Background and Objective: Morphine can cause harmful effects in the ovaries. The silver nanoparticles (Ag-NPs) used in health care because of antimicrobial properties, can diffuse into the brain blood barrier. This study investigated the protective effect of Ag-NPs on the induction of polycystic ovary (PCO) due to injection of morphine intra-ventromedial hypothalamus (intra-VMH) of rat compared...

The temporal organization of some physiological parameters in rabbits by evaluating the circatrigintan rhythms of some haematochemical and haematological parameters, and of rectal temperature, in New Zealand white rabbits was studied. For 30 days before the study the animals all followed the same pattern of daily activity with the natural photoperiod for that season, and were fed on hay ad libi...

while legumes are regarded as good sources of protein they may be poorly digested, so it is useful to determine their digestibility which would give a desirable objective in a breeding programme. in this respect two series of experiments were performed as follow: true digestibility of the nitrogen (tnd) of cooked white haricot beans (phaseolus vulgaris) was measured by feeding it to rats at 20,...

BACKGROUND The aim of this study was to evaluate the effects of onion powder consumption on treatment of Non-alcoholic Fatty Liver Disease (NAFLD) in an experimental model of disease. METHODS Sprague-Dawley rats were fed high-fat (HF) diet for seven weeks to induce the NAFLD. Then, they were treated by either the same diet (HF), or high-fat diet plus 7 % onion powder (HF + onion), or chow die...

BACKGROUND At present, the treatment options available to delay the onset or slow down the progression of Alzheimer's disease (AD) are not effective. Recent studies have suggested that diet and lifestyle factors may represent protective strategies to minimize the risk of developing AD. Date palm fruits are a good source of dietary fiber and are rich in total phenolics and natural antioxidants, ...

First-growth orchardgrass and alfalfa were harvested at two stages of maturity, treated with formic acid plus formaldehyde, and ensiled as direct-cut silage during 1978 and 1979. The 1978 silages were fed to eight yearling Holstein heifers (average BW 273 kg), and the 1979 silages were fed to eight yearling Holstein steers (average BW 264 kg) in replicated 4 x 4 Latin square experiments to meas...
