On a typical dairy farm today, large amounts of N are imported as feed supplements and fertilizer. If this N is not recycled through crop growth, it can lead to large losses to the atmosphere and ground water. More efficient use of protein feed supplements can potentially reduce the import of N in feeds, excretion of N in manure, and losses to the environment. A simulation study with a dairy fa...

Vascular dysfunction contributes to the pathogenesis of various cardiovascular diseases. Dietary supplements, including fish oil, dietary fibers, and various natural products, and exercise training exert vasoprotective effects. However, the mechanisms underlying the vasoprotective benefits of dietary supplements and physical activity demand extensive investigation. Accumulating evidence suggest...

In two consecutive years, primi- and multiparous, spring-calving Hereford and Hereford x Angus cows (n = 32, yr 1; n = 42, yr 2) were used to determine the effects of supplements and lactational status on forage intake, digestibility, and energy intake. Cows were randomly alloted to treatments after being blocked by age, breed, and weight. Supplements fed during gestation provided .55 kg/d of C...

A meta-analysis was undertaken to examine the effects of different supplementation strategies on production beef cattle grazing tropical pastures during wet and dry seasons in Brazil. The database built with 132 studies published from 1999 2010, which accounted for 6,275 individual animals. supplements assessed were classified into three groups: energy supplement containing <20% crude protein (...

This study examined the traditional (single and multivitamin/mineral supplements) and nontraditional supplement (herbals, botanicals, and other biologic and nutrient supplements) use by female athletes. Frequency, reasons for use, and sources of supplement information were assessed with a self-report questionnaire. Participants were 162 collegiate female varsity athletes. More than half of all ...

the study was conducted to evaluate the effects of feeding varying levels of ficus sycomorus leaf forages as protein supplements to a basal diet of urea treated maize stover. four yankasa goats averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. the basal diet (urea treated maize stover) was supplemented with 0 (t1), 50 (t2), 100...

I . Diets containing varying lcvels of crude protein (CP) in the range 9.5-18.5 "/b with and without supplements of diammonium citrate (DAC) as a source of non-protein nitrogen (KPN) were given to 160 growing chicks from z to 4 weeks of age, and their livers were assayed for glutamate dehydrogenase (GDH) activity. 2. Growth rate and total liver protein were increased by raising the protein leve...

BACKGROUND Malnutrition occurs frequently among patients in rehabilitation, leading to poorer outcomes. Evidence of the effects of interventions to prevent or treat malnutrition is required to guide clinical practice in this setting. This systematic review aimed to determine the effect of oral nutrition interventions implemented in rehabilitation on nutritional and functional outcomes. METHOD...

Iron (Fe) is an essential micronutrient for human growth and health. Organic iron is an excellent iron supplement due to its bioavailability. Both amino acids and peptides improve iron bioavailability and absorption and are therefore valuable components of iron supplements. This review focuses on protein hydrolysates as potential promoters of iron absorption. The ability of protein hydrolysates...
