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.

Interactions among nutrients such as vitamins and minerals are of great importance in poultry nutrition and can negatively affect the performance of birds if not considered (Mir et al. 2021). Providing protection to the cells against the oxidative damage by free radicals and lipo-peroxides, selenium (Se) is an integral part of Se-dependent antioxidant enzymes, and thus involved in the antioxidant defense system of the body (Finkel and Holbrook 1991). Traditionally, in poultry diets, Se...

The release of P into the environment is a target that must be achieved not only for economic and environmental reasons, but also to increase the sustainability of animal production. The impact of dietary Ca on P digestibility, and consequently the level of the inclusion of inorganic P sources in the feed, plays an important role by hindering the phytase to hydrolyse phytate-P (Sommerfeld et al., 2018). The aim of this trial was to investigate the impact of lowering the inclusion of...

Nutritional factors of gut inflammation (D. Korver) The intestinal tract is one of the largest, if not the largest, surface areas exposed to the environment of humans and poultry (Ferrer et al., 2003; Helander and Fandriks, 2014). Although the digestive tract is contained within the body, the lumen is actually outside of the bird. Therefore, although the function of the intestinal tract is usually thought of as being the uptake of nutrients, it has another important function:...

I. INTRODUCTION Acid binding capacity (ABC) of an ingredient, through its effect on gastric pH, plays an important role in the digestion and absorption of nutrients in poultry. The ABC is defined as the resistance of a feed ingredient to the pH reduction by gastric acid. Limestone, the major Ca source in poultry diets, has a high ABC (Lawlor et al., 2005), which can increase the digesta pH and, influence the solubility and digestibility of nutrients, including minerals. The average...

1. Introduction Poultry farming is integral to global animal agriculture, supplying a vital source of economical protein for an expanding human population [1]. The industry makes up more than a third of the world’s meat production, and it is expected to grow to around half of all meat production, reaching 182 million tons in the next ten years [2]. Notwithstanding, the industry faces ongoing health challenges that jeopardize productivity and animal welfare, with necrotic...

Juan José Mallo, Technical and Commercial Director at Norel, explains how the company is helping nutritionists increase phosphorus release in animal diets. By reducing calcium–phytate complex formation and introducing calcium pidolate, a 100% available organic calcium source, it’s possible to unlock more phosphorus from plant ingredients while maintaining adequate calcium levels. ...

Laying hens have a cyclic reproductive physiology that requires high dietary protein and energy levels for yolk and albumen formation in the early morning and high dietary Ca levels for shell and membrane formation in the afternoon/evening. Therefore, feeding one diet throughout each day may be problematic as there is excess Ca in the morning and excess protein/amino acids and energy in the afternoon/evening. To minimise excess nutrients, there is increasing interest in alternative...

Introduction With genetic improvement changes, today poultry species are more sensitive to nutritional and management changes which can easily induce osmoregulatory perturbation that can cause flushing (Many, 2023). A typical layer farm of 100,000 hens produces 1,500 to 2,000 tons of manure every year (Chai, 2012). And 1000 broilers chickens produce up to 1370 lbs of manure per in a growing cycle (Parker et al., 1959). Manure is acquired by the agricultural industry for land...

DESCRIPTION OF PROBLEM There are growing concerns that the continual feeding of inorganic P is leading to the development of eutrophication of surface waters. Excessive P runoff from soil causes an accumulation of P in water sources, and this can result in toxic algal blooms and fish kills [1]. The availability of P from feedstuffs of plant origin is low for poultry because a greater proportion of the total P is present in the phytate form, a form that has low availability...

Introduction It is assumed that net energy (NE) represents the most accurate way to value a feed for productive purposes (Barzegar et al., 2020; Liu et al., 2017; Wu et al., 2019). This explains the variations in the metabolic utilization of metabolizable energy (ME) from nutrients and ingredients (Noblet, 2015), explains the loss of energy as heat (Swick et al., 2013), and allows for more accurate prediction of the productive response of animals. The composition of diets (type...

Introduction Increasing the efficiency of protein utilization is an important issue in livestock for production. Apart from the cost of protein (the input side), the issue is also driven to reduce nitrogen excretion (the output side) to limit the environmental impact of livestock production. The quantitatively most important role of dietary protein is to provide the amino acids for animal-derived products, such as meat, milk, and eggs. The similarities in the amino acids composition...
