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.
Influenced by temperature and ultraviolet radiation, the activity of virus is limited in summer, but the higher temperature leads to the decrease of feed intake of chickens. When the feed intake decreases, the intake of energy and protein decreases accordingly. At the same time, the concentration of digestive enzymes in intestine decreases due to the increasing water intake. And the time of chyme passing through digestive tract shortens. The digestibility of nutrients, especially most...

Introduction Mycotoxins are secondary metabolites of low molecular weights produced by certain strains of filamentous fungi such as Aspergillus, Fusarium and Penicillium, which invade crops in the field and may grow on foods during storage under favaourable conditions of temperature and humidity. The most common mycotoxins are aflatoxins, fumonisins, ochratoxin A, trichothecenes, zearalenone, and out of which aflatoxins (AF) commonly contaminate a wide variety of tropical and...

Iron plays an important role in poultry nutrition. From the active site in the heme group in blood to functional groups in enzymes, iron is critical for metabolic balance. These roles for iron aren’t unique to animals, as it is also important in the growth of bacteria, including pathogens. Also, iron is a significant antagonist against minerals, vitamins and other nutrients in diets. The right balance of active and available iron is critical to optimize broiler growth. Several trials...

INTRODUCTION The worldwide occurrence of mycotoxins producing fungi and their ability to grow on the variety of economical important cereal crops have rendered them as unavoidable contaminants of human and animal food and feeds. The family of ochratoxins consists of three members known as ochratoxin A, ochratoxin B and ochratoxin C among these ochratoxin A (OTA) is the most toxic one. They are the second major group of mycotoxins characterized after the discovery of aflatoxins....

Introduction Phosphorus (P) is an important mineral required in poultry diets for normal growth and development (Ankra-Badu et al., 2004). It constitutes the costliest mineral nutrient in animal nutrition and is the third most expensive component in non-ruminant diets, where the first two are energy and protein (Boling et al., 2000). Countless studies have been focused on the P requirement for poultry, not only due to its economic importance but also due to its...

Introduction Broiler diets consist basically of plant-derived ingredients. These feeds are characterized by having a large part of phosphorus in the form of phytate (Rostagno et al., 2011), which is poorly hydrolyzed by monogastric animals (Ravindran et al., 1995), which do not have a significant activity of enzymes such as phytase throughout the gastrointestinal tract. However, in addition to complexing with phosphorus, the phytate molecule is also able to bind to other...

INTRODUCTION The aflatoxins are group of closely related fungal secondary metabolites produced by certain strains of Genus Aspergillus. The aflatoxins are reported to be carcinogenic, mutagenic and teratogenic and toxic which causes severe economic loss in poultry due to poor growth, reduced feed intake, poor FCR and immunosuppression rather than heavy mortality. Several studies have been conducted on dietary supplementation of nutrients for counteracting aflatoxicosis in...

INTRODUCTION Poultry farming has metamorphosed into an organized industry in recent past and registered a rapid growth over last three decades in India. Many problems are continuously challenging against successful poultry farming operations and the common one is threat of mycotoxicosis in poultry.

Presence of mycotoxins in feed is one of the major constraints in maintain feed quality because the mycotoxins are widely present in feedstuffs around the world and may affect production even in very low concentration. The most widespread and in most studied group of mycotoxins, aflatoxins are of great concern in warm and humid climatic conditions like India (Singh et al. 2010). Aflatoxin in poultry causes reductions in growth performance (Silambarasan et al. 2013, Patil et al. 2013),...
