Minerals in poultry nutrition
Minerals in poultry nutrition are typically classified as macro- or micro-minerals, depending on the levels needed in the diet. The macro-minerals include calcium, phosphorus, chlorine, magnesium, potassium, and sodium. Requirements for the macro-minerals are typically expressed as a percentage of the diet, while the requirements for the micro-minerals are stated as parts per million. Although the quantities required for micro-minerals are lower than for macro-minerals, they play an essential role in the body's metabolism. The micro-minerals include copper, iodine, iron, manganese, selenium, and zinc.
Introduction Concerns about the possible contribution of P runoff from the application of poultry litter to eutrophication of surface waters has focused attention on means of reducing phosphorus excretion (Edwards and Daniel, 1992; Sharpley, 1999). Because of the demands for adequate skeletal development of the rapidly growing broiler and the variability of phosphorus content in...

For the last two decades poultry nutritionists have been dealing not only with how to improve production efficiency, but also how to improve the nutritional profile of poultry meat and eggs. When compared to beef and pork, poultry meat is undoubtedly the leanest, but due to consumer demands the industry cannot be complacent about the current advantage. The recent reduction in animal fat and total cholesterol consumption caused a significant erosion of the previously accepted dietary image of...

I. INTRODUCTION Calcium (Ca) and phosphorus (P) are essential minerals for many biological processes and skeletal health, however, they have a complex interactive relationship. Phytate is the naturally occurring storage form of P in plants, with the main storage site of phytate-P being seeds (Tamim et al., 2004). As poultry diets are comprised mainly of seed based ingredients, there is a considerable amount of phytate-P...

1. INTRODUCTION The metabolism of vitamin D, calcium and phosphorus within the chicken is uniquely integrated. The absorption of intestinal calcium depends on many factors but one of the most important is vitamin D (Ameenuddin, Sunde et al. 1985). There is obscurity regarding the exact mechanisms of calcium absorption across the intestine, however it is known that vitamin D is essential for the synthesis of calcium binding protein (CaBP) in the...

Danisco Animal Nutrition, a business division of DuPont Industrial BioSciences, hosted a VIP seminar before the main EPC conference kicked off on June 23. Dr. Peter Plumstead began the seminar with a presentation that separated the facts concerning nutrient release from phytase from the fiction. He stressed the importance of establishing robust estimates of calcium and phosphorus contributions when selecting phytase products and the necessity of species-specific...

Materials and methods Performance study A 42-d performance study was conducted utilizing 2640 Straight Run Broiler chicks in 88 pens containing 30 chick/pen. Each pen contained 1 water fountain and a 50 lb capacity feed tube. Pen density provided 0.67 ft 2 per bird initially. Prior to trial start all pens were carefully inspected to ensure that there were no...

Phytate Phytin (deposited complex of inositol hexaphosphate with potassium, magnesium and calcium), more recognized in animal nutrition as phytate, is the major storage form of phosphorus (P) present in seeds. Originally recognised as a source of P during germination, the presence of phytin in the seed during the germination process is now also known to play an important role in preventing oxidative stress and thus...

I. INTRODUCTION The modern broiler chicken has been genetically selected for rapid growth, increased muscle mass and heavier breast weight (Garner et al., 2002). This increase in production may also be associated with poor leg health and lameness and is often linked to skeletal abnormalities due to reduced bone mineralisation. Poor leg health and lameness affects millions of broiler chickens worldwide, with lame birds having significantly reduced...

I. INTRODUCTION Historically, there has been a move from the use of a total Ca (tCa) to total P (tP) ratio system (NRC, 1950) to a tCa to inorganic P (iP) ratio (NRC, 1954), to the use of tCa to available P (aP) that appeared in the 1984 NRC. In 1950, the requirements were 1.0% tCa and 0.6% tP (1.66 tCa:tP) (NRC, 1950) and, in the 1954 NRC, the qualification was made giving importance to the availability of P by specifying that, of the 0.6% tP...

A battery study was conducted to evaluate effect of different sources of selenium (Se) on growth performance, glutathione peroxidase (GPx) activity and tissue Se deposition of young broilers. A semi-purified diet containing corn starch, dextrose, and torula yeast was formulated to meet requirement of broilers for all nutrients except Se. The Se level was formulated to be 0.11 ppm but analyzed to be 0.23 ppm. The study consisted of 9 treatments - negative...
