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.
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...

A 42 d trial was conducted to determine the response of MINTREX ® (metal methionine hydroxy analogue chelate) vs. industry levels of ITMs (inorganic trace minerals) on performance, immune response, and litter trace minerals concentration by feeding broiler chicks diets containing varied levels of supplemental Zn, Cu and Mn as chelates in comparison to industry levels of inclusion of respective inorganic trace minerals...

A 15 week (wk 21-36) study was conducted in a commercial broiler breeder facility to determine the impact of feeding reduced levels of MINTREX ® (metal methionine hydroxy analogue chelate) vs. industry levels of ITMs (inorganic trace minerals) in breeder hens on egg quality, hatching rate and progeny quality. A total of 15200 male line of Hubbard breeder hens were distributed into 4 houses (with floors having 1/3 slats and...

Trace minerals are important for broiler growth and are used in various physiological, digestive and biosynthetic process of the body. Trace minerals act as cofactors in many enzymes and are associated with proteins involved in intermediary metabolism, hormone secretion path ways and the immune system (Dieck et al., 2003). In broilers, organic trace minerals are better absorbed and utilized and have a greater bioavailability than inorganic trace minerals (Bao et al., 2007)....

I. INTRODUCTION
Limestone is composed primarily of CaCO 3 and is commonly used as a source of calcium (Ca) in poultry diets. Pure CaCO 3 has a molecular weight of approximately 100g/mole and so is around 400 g/kg Ca. However, CaCO 3 sources used in animal feeding are typically only 370-380 g/kg Ca, sometimes less, due to the presence of other minerals such as Mg or Fe. Furthermore, the bioavailability of...

I. INTRODUCTION Calcium (Ca) and phosphorus (P) requirements of poultry have been investigated extensively over the past 50 years. However, the interactions of these two macrominerals are highly complex and are not easily interpreted. The majority of published animal nutritional research is based either on altering a single food property at a time or where multiple factors are changed. While these approaches are valuable in some circumstances,...

INTRODUCTION Trace minerals are required to ensure the health and productivity of livestock species. However, requirements are poorly defined in most species and our understanding of the relationship between mineral source and its ability to meet specific requirements lacks precision. As a consequence inorganic trace minerals (ITM) are included in poultry diets at levels several times NRC [3] recommendations. Low absorption coupled with high...

To prove it, Adisseo has already invested more than 1 million euros in more than 20 trials across species since 2008 to figure out the synergistic value of Rovabio ® Max, a combination of Rovabio ® Excel, Adisseo's carbohydrase and phytase.
Knowing Rovabio ® Excel and phytase effects separately is not sufficient; as they may have contrary effects, for example on feed intake. Both...

WATER Water is probably the most important nutrient for poultry because a lack of adequate supply will adversely affect the bird's performance more quickly than a shortage of any other nutrient. This is why it is so important to keep an adequate supply of clean, fresh, cool water before the birds at all times. An automatic waterer, placed in the coolest area of the house or pen is probably best for most small-flock operations. If manually...

Dear Users,
This is an interesting forum from our Spanish community, generated by Gabriella Olivieri from Venezuela:
Hi, I want to ask a question about the supply of minerals in broilers:
I provided 200 grams of mineral (FOSVIT 20 of the CIA. Turtle Brazil) for every 40 kilos of concentrate, at 2 days after arriving the chicks, it has improved the yield in weight, but there is mortality at 16 days by infarction, and at 35 days this mortality is increased to 13.
I thank you any...

Achieving maximum health and performance of poultry requires nutritionally balanced diets. One of the common issues with regard to back yard flocks relates to poor or inadequate feeding programs that can lead to vitamin and mineral deficiencies for the birds. Vitamins and minerals are very important components of a chickens diet and unless a formulated ration is feed, it is likely that deficiencies will occur. Poultry require all known vitamins except C. Some vitamins are soluble in...
