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
Nutrition plays a major role in the performance of layer birds. Feed management is the most important practice to get egg production at a right time, maximum peak production, long standing peak production, standard egg size, good cull bird weight and reduced feed cost per egg. Body weight should be taken every week from 1 st week to 18 th week of age, the birds with less body weight...

It's not always that the high performance brings production stress to poultry, it's the way you deal with it. The high performing animals and feed is need of the competitive world. The crucial mission is to support them adequately to perform. Some choices are available as feed additives to control the production stress. But they are limited by their stability, safety and...

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...

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...
