The aim of the experiment was to assess content N-corrected apparent metabolisable energy (AMEn) in dried Sea buckthorn berries (SB) when fed Ross 308 broiler chickens. Two experimental diets (basal and basal + 12 g/kg milled SB berries) were an equal number replicated pens (n=8; two birds each) from 7 21d age, following randomisation. diet formulated meet breeder’s recommendations. inclusion a...

D-glucose regulates maintenance and function of pancreatic beta-cells. Several studies have shown that IRS-2, but not IRS-1, is necessary to maintain and sufficient to expand functional beta-cell mass. We therefore analyzed the expression of IRS-2 and IRS-1 in beta-cells after culture in the presence of various concentrations of D-glucose and other metabolisable or non-metabolisable hexoses. D-...

Strontium is currently prescribed for patients with osteoporosis to increase bone density and reduce bone fractures but its relevance in animal nutrition is obscure. In order to investigate the effect of supplemental strontium and vitamin D3 on performance, egg quality and skeletal integrity in poultry a total of 108 laying hens, 99 weeks of age, were fed three levels of strontium (0, 500 mg/kg...

These experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. Ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

OBJECTIVE To estimate physical activity energy expenditure (AEE) in groups of free living infants in the first year of life. DESIGN Mixed longitudinal study of 124 healthy infants, using 232 estimations of AEE made between 1.5 and 12 months. Infants studied at more than one time point were treated as new cross sectional data points. Total energy expenditure and body composition were estimated...
