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.
Latin American Scientific Conference
In October, 2016, the Poultry Science Association successfully held its first-ever Latin American Scientific Conference in Campinas, SP, Brazil.
One of the highlights of this conference was the symposium Update on Calcium and Phosphorus Digestibility in Poultry: Different Approaches and Implications.

BACKGROUND Calcium (Ca) is an essential nutrient for poultry that is generally provided to laying hens at approximately 4.6% of the total feed volume. Calcium is usually supplied to layers as a calcite grit or flour i.e. limestone (CaCO 3 ) and also as part of the inorganic phosphorus (P) supplye.g. dicalcium or monocalcium phosphate. Though, in some markets, meat and bone meal may also contribute...

Poultry manure fertilizer contains all the essential nutrients required for crop production, and its value as an organic fertilizer and a source of plant nutrients has been recognized for centuries. Even with its beneficial effects on plant growth, however, manure constitutes only a small percentage of the nutrients applied to cropland when compared to commercial fertilizer. Poultry manure fertilizer is not used to its maximum...

INTRODUCTION Nowadays, there are a lot of concerns to finding non-synthetic alternatives for antibiotics among the researchers. The positive effects of herbal plants on broilers have been reported by many studies. Herbs showed anti biotical potential, hypocholestrolemic effects and growth promoting, which have drawn the researcher’s attention themselves [1]. Organic poultry...

1. Introduction Aflatoxins, which are secondary metabolites produced by the Aspergillus flavus and parasiticus species of mold, are among the most potent natural carcinogens. No animal species is immune to the toxic effects of consuming food contaminated with aflatoxin and Aspergillus species are known to infect important agricultural crops. Therefore, in cases where preventative management strategies in...

Introduction A delicate balance between antioxidants and prooxidants in cells is an important determinant of various physiological processes and maintenance of this balance is the main aim of so called an integrated antioxidant system built in the animal body. This system was developed during evolution to provide an antioxidant defence and give a chance for animals to survive in oxygenated atmosphere. Recent data suggest...

INTRODUCTION There are several challenges associated with maintaining profitability in large tom turkey production. Among these are choosing the commercial genotype or strain that optimizes feed conversion ratio (FCR), ending weight (EW) and breast yield according to each company’s market needs. There have been concerns with “skeletal weakness” in commercial toms for over 40 years. In 1971 the National...

INTRODUCTION Aflatoxins (AF), a group of closely related, extremely toxic chemicals, are produced by Aspergillus flavus and Aspergillus parasiticus and can occur as natural contaminants of poultry foods (Edds and Bortell, 1983; Leeson et al., 1995). Aflatoxicosis is an important disease of livestock and poultry. AF may be produced in food and foodstuffs before harvest, between harvest and drying, in storage and after...

Copper (Cu) has been widely used at pharmacological levels (e.g., 125 ppm) as growth promoter in poultry. However, the mechanism by which high levels of Cu promote growth remains to be determined. It is commonly recognized that Cu exerts anti-microbial effects in the gut but there is not much direct and consistent data showing that Cu alters the population of bacterial species in birds. The objective of this study was to understand the mechanism by which Cu...

Originally published in Research in Veterinary Science 2001, 71, 59-66 AFLATOXINS (AF), are secondary metabolites produced by certain fungi belonging to the genus Aspergillus and can occur as natural contaminants of poultry feed (Leeson et al 1995, Oguz 1997). The toxicity of AF in broiler chickens has been widely investigated by the determination of their carcinogenic,...
