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.
Originally published in Research in Veterinary Science 2000, 69, 89–93. 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. Aflatoxicosis is an important disease of livestock and poultry. The frequent AF contamination of agricultural...

The U.S. Poultry industry operates in an integrated manner, with the majority of birds owned and managed by relatively few companies. Ten companies represent seventy percent of the 8.8 billion broilers marketed annually in the U.S. The vast majority of turkeys raised in the U.S. are owned by three well-known, leading companies; the top 16 laying hen companies represent 70% of the 258 million laying hens in the U.S. (Poultry USA, 2010). The industry is very...

Introduction Concerns about the possible contribution of P runoff from the application of poultry litter to eutrophication of surface waters has focused attention on means of reducing phosphorus excretion (Edwards and Daniel, 1992; Sharpley, 1999). Because of the demands for adequate skeletal development of the rapidly growing broiler and the variability of phosphorus content in...

For the last two decades poultry nutritionists have been dealing not only with how to improve production efficiency, but also how to improve the nutritional profile of poultry meat and eggs. When compared to beef and pork, poultry meat is undoubtedly the leanest, but due to consumer demands the industry cannot be complacent about the current advantage. The recent reduction in animal fat and total cholesterol consumption caused a significant erosion of the previously accepted dietary image of...

I. INTRODUCTION Calcium (Ca) and phosphorus (P) are essential minerals for many biological processes and skeletal health, however, they have a complex interactive relationship. Phytate is the naturally occurring storage form of P in plants, with the main storage site of phytate-P being seeds (Tamim et al., 2004). As poultry diets are comprised mainly of seed based ingredients, there is a considerable amount of phytate-P...

1. INTRODUCTION The metabolism of vitamin D, calcium and phosphorus within the chicken is uniquely integrated. The absorption of intestinal calcium depends on many factors but one of the most important is vitamin D (Ameenuddin, Sunde et al. 1985). There is obscurity regarding the exact mechanisms of calcium absorption across the intestine, however it is known that vitamin D is essential for the synthesis of calcium binding protein (CaBP) in the...
