The influence of different protein sources on Zn absorption was evaluated in healthy adults by radioisotopic labelling of single meals, followed by whole-body retention measurements 14 d after intake. Semi-synthetic liquid diets were used for the evaluation of different animal-protein sources and dephytinized soyabean-protein isolate (< 0.01 g phytic acid/kg). Zn absorption was measured in the ...

Saponins are naturally occurring amphiphilic molecules and have been associated with many biological activities. The aim of the present study was to investigate whether soya saponins trigger the onset of soyabean-induced enteritis in Atlantic salmon (Salmo salar L.), and to examine if dietary soya saponins increase the epithelial permeability of the distal intestine in Atlantic salmon. Seven ex...

Glyceollins, one family of phytoalexins, are de novo synthesised from daidzein in the soyabean upon exposure to some types of fungus. The efficiency of glyceollin production appears to be influenced by soyabean variety, fungal species, and the degree of physical damage to the soyabean. The compounds have been shown to have strong antioxidant and anti-inflammatory activities, and to inhibit the ...

There are considerable differences in the basic feeds used by the Australian Pig Industry relative to those used overseas. Maize and soyabean meal form the basis of the USA and Canadian feeding systems, and barley and soyabean meal the basis of the feeding systems in Western Europe. In Australia, wheat, barley and sorghum are the major cereals fed, and meat and bone meal, soyabean meal, cottons...

________________________________________________________________________________ Abstract This study was performed to investigate the effects of different oils in the diets of laying quail on their performance, egg quality, serum lipids and fatty acid composition of egg yolk. One hundred and ninety two 12-wk old Japanese quail were allocated to eight groups with two replicates containing 12 qua...

In this study, we chose a carnivorous fish, turbot (Scophthalmus maximus L.), to examine its nutrient-sensing and metabolic responses after ingestion of diets with fishmeal (FM), or 45% of FM replaced by soyabean meal (34·6% dry diet) balanced with or without essential amino acids (EAA) to match the amino acid profile of FM diet for 30 d. After a 1-month feeding trial, fish growth, feed efficie...

The aim of the present study was to investigate the anti-hypertensive and angiotensin-converting enzyme (ACE) inhibition effects of soyabean protein hydrolysate in spontaneously hypertensive rats (SHR). Soyabean protein hydrolysate was prepared by peptic hydrolysis and was added into the feed of SHR (0% for the S0 group, 0.5% for the S1 group, and 1% for the S2 group) for 12 weeks. Systolic blo...

After feeding of rats with the raw soyabean diet, serum polyamine concentrations (primarily spermidine) were significantly increased at 6 and 12 h (Table I ) . N o similar increases were apparent in the control animals. After 24 h, the circulating levels of polyamines returned to control values and subsequently the total polyamine content in the blood was below normal. These later changes sugge...

For a number of years, lipid emulsions have been used in the nutritional support of surgical and critically ill patients, with the aim of supplying substrates to meet energy demands and providing building blocks for wound healing and tissue repair. Traditionally, these emulsions have been based on soyabean oil, which is rich in the n-6 PUFA linoleic acid (18 : 2n-6). More recently, the impact o...

To examine the hormonal effects of isoflavones, of which soyabean is a rich source, fifteen healthy nonvegetarian premenopausal women were studied over 9 months. They lived in a metabolic suite for between 4 and 6 months where their diet and activity levels were kept constant and their hormonal status was measured over two or three menstrual cycles. During one (control) menstrual cycle a normal...
