Modern analytical techniques and instrumentation make it possible to accurately determine trace mineral concentration in feed and animal tissues. Unfortunately, however, such determinations provide no information on utilization of the minerals by animals. Utilization involves the concept of bioavailability and is critical in the selection of a suitable source of the mineral. In terms of trace m...

In acidic forest soils, availability of inorganic nutrients is a tree-growth-limiting factor. A hypothesis to explain sustainable forest development proposes that tree roots select soil microbes involved in central biogeochemical processes, such as mineral weathering, that may contribute to nutrient mobilization and tree nutrition. Here we showed, by combining soil analyses with cultivation-dep...

BACKGROUND Many factors, such as heredity, ethnicity, nutrition and other lifestyle factors, have been related to bone mineral density in postmenopausal women. Additionally, bone mass has been significantly associated with decreased estrogen levels. However, fewstudies have been conducted on premenopausal women. The present study was designed to estimate the relationship between low bone minera...

poultry requirments for vitamins and minerals are met from two sources feed ingredients and premixes.in practical poultry nutrition, the role of feed ingredients is over looked. this experiment was conducted to evaluate the effects of the time of vitamin and mineral premixes withdrawal on growth and economic performance of broilers. four hundred and fifty, one day-old male broiler chickens (ros...

Mineral nutrition research in recent years has focused on reducing mineral excretion; however, very little work has focused on accurate determination of mineral requirements. To more accurately define and understand mineral requirements, it is essential that a better understanding of mineral absorption mechanisms and their regulation be achieved. This is particularly important because the cost ...

Minerals are critical to an individual's health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas (Gorilla beringei beringei) in the Bwindi Impenetrable National Park, Uganda. Mountain gorillas acquire the majority of their minerals from herbaceous leaves, which constitu...

AIM To examine early factors in bone mineral accretion in cystic fibrosis (CF). METHODS In 22 prepubertal children with CF and mild lung disease, the relation between total body bone mineral density (BMD) and measures of body composition, biochemistry, lung function, and physical activity was studied. RESULTS There was a non-significant mild reduction in mean total body BMD. No relation was...

Objective: To determine how the balance between mineral base, and carbonic and organic acids is altered to cause metabolic acidosis in preterm infants. Study Design: Mineral balance and arterial blood measurements of 3 groups of preterm infants given 5 different Total Parenteral Nutrition (TPN) regimens were analyzed. Mineral base was measured as the difference between mineral cations and anion...

OBJECTIVES This study's objective was to assess patient nutrition inquiries and related physician resources to identify the nutrition topics about which physicians most need information for patients and practice. METHODS A survey was mailed to a 50% random sample of Washington Academy of Family Physicians (WAFP) members (n=778) to identify the top 10 patient nutrition inquiries that the physi...
