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.
Dr. Bob Buresh, executive regional technical services manager, North America, points out the main benefits of Mintrex in breeders. Dr. Buresh told Engormix during IPPE 2020 that Mintrex® is a very defendable mineral source and brings value to the producers.

Introduction: Pathogens and Iron Requirement E. coli accumulate large amounts of iron via multiple transport systems including enterochelin transport system (McIntosh and Earhart, 1977). Three tetracyclines were found to possess iron-chelating activity as part of the antibiotic activity. (Greinier et al., 2000) Clostridium perfringens produced larger colonies, with…ferredoxin, than that on the control medium. (Osman et al. 2013) Proposed that...

INTRODUCTION Choline, a rediscovered vitamin B 4 that mostly exists in the form of phospholipids, plays a critical role in several biological functions in poultry. It is essential for building and maintaining cell membranes and organelles, such as mitochondria and microsomes, and for normal maturation of the cartilage matrix of the bone [1]. Moreover, it is an essential component of acetylcholine, the most common neurotransmitter in the nervous system involved in the...

USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at Texas A&M University in College Station, Texas, in which the role dietary calcium plays in necrotic enteritis (NE) development and pathogenesis was examined. The research was made possible in part by an endowing Foundation gift from the Sanderson Farms and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A...

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 Nanotechnology is regarded as the ability to manipulate measure, manufacture and make predictions at the scale of 1–200 nm. 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...
