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 The main idea of using phytase in the diet for broilers is based on the reduction in the content of available phosphorus ( av P) accompanied by the inclusion of this enzyme. With this, it is expected that the av P content present in the diet, added to the content of phytate P ( phy P) made available by the catalytic action of the phytase, meets the P requirement of the bird (HAN et al., 2009). The industry related to broiler nutrition,...

Introduction Calcium reduction and phytase supplementation were considered an important combination in broiler nutrition. Wooden breast (WB) has been considered one of the most important challenges in the Poultry Industry in the 21st century. The superdosing of phytase can affect metabolic functions in the early life of broilers, and the studies with the interaction of this enzyme with calcium, phosphorus and carcass evaluation must be incremented. Based on this, calcium...

Recent findings indicate that altering broiler chicken diets can help mitigate the severity of woody breast and white striping, two poultry meat quality issues that appear to be increasing in prevalence in many markets. A multitude of poultry researchers are exploring various approaches to eradicate these myopathies, and Novus International’s poultry scientists have recently concluded that organic trace minerals fed in combination with an antioxidant can...

At the nanometer dimension, materials revealed novel properties, different to those of both, the isolated atom and bulk material that the properties depending largely on the size of the particles from which the material is made. The environmental stress can decrease production and all other important economical...

Introduction It is well known that any molecule with an atom that contains a single unpaired electron in its outer orbit is termed an oxidant. These atoms are unstable and have a strong attraction for the electrons of other atoms or molecules in order to regain their resting state. The process of transferring electrons to the oxidant is termed oxidation, and a new free radical is formed in the process (Surai, 2002). In fact, oxidation is a very general process, which affects...

Introduction There exist a general antagonism between growth rate and reproduction in domestic animals. Breeds selected for high growth rate allocate nutrients preferably in body mass development. This has detrimental effects egg production, fertility and livability. Therefore it is necessary to control the development of body weight development of broiler breeders through reduced feed intake. The common practice is a single meal allocation in the morning using a balanced diet....

Introduction The high cost of inorganic phosphate has influenced the direction of research and the industry to discover alternative sources of phosphorus (P) or improve the availability of P, for broilers. The phytase enzyme has been highlighted in the nutrition of non-ruminants as a tool to reduce the dietary inclusion of inorganic P and to decrease nutrient excretion through the excreta (WALDROUP et al., 2000; GRAÑA et al., 2013). With the growth and narrowing of an...

Stresses in poultry production Commercial poultry production is associated with various stresses leading to decrease of productive and reproductive performance of growing chickens, parent birds as well as commercial layers. In general, there are four major types of stress in poultry industry: technological, environmental, nutritional and internal stresses (Surai and Fisinin, 2016a; 2016b; Table 1).In fact, a list of...

INTRODUCTION It has been reported that the low locomotor activity of broilers coupled to their high initial growth rate of broilers results in leg problems and gait abnormalities. Long times spent sitting on wet litter may cause breast and leg skin lesions, which may contribute for the deterioration of the flock well-being (McGeown et al., 1999; Vestergaard & Sanotra, 1999; Weeks et al., 2000; Bokkers & Koene, 2004; Bessei, 2006).

Introduction Calcium is an essential nutrient to the body of birds, as it participates in several biochemical functions and in bone formation. The deficiency of this mineral can cause damages; thus, it is essential to adequately meet the nutrient requirements in the different stages of bird development. Its metabolism is closely related to that of phosphorus (P) (Mello et al., 2012), which leads to caution in the formulation of balanced rations for these minerals to obtain...
