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.

This study investigated whether hydroxy-selenomethionine (OH-SeMet) improves broiler oxidative stress response to a greater extent than sodium selenite (SS) or seleno-yeast (SY) under environmental stress. Day-old male Cobb 500 broilers (12 cages/diet, 9 broilers/cage) were fed a selenium (Se)-deficient diet (0.047 mg Se/kg) supplemented with SS, SY or OHSeMet at 0.3 mg Se/kg for 42 days. Animals were raised at a high stocking density (18 broiler/m²) and during the summer period...

Calcium digestibility can vary dramatically depending on the Ca source, limestone solubility, source of phytate and addition of phytase (Li et al., 2021). However, there is no agreement in the literature about the most appropriate method for determining Ca digestibility (Li et al., 2017). In the current study, the apparent ileal Ca and P digestibility was determined in diets varying in Ca content, with and without phytase supplementation, based on the short-term protocol described by Kim et...

1. Introduction Humphry Davy, a British chemist, was the first to isolate and investigate the chemistry of calcium (Ca) and to recognise it as an essential component of bone in 1808. Ever since, it has been the subject of a voluminous amount of research in both human and animal nutrition. Today, the biological significance and economic importance of Ca in animals are intuitive. Calcium is the most abundant mineral in the body and is essential for the skeletal health and...

I. INTRODUCTION Forecasting is fraught with difficulties associated with poor data and unknown unknowns. Fortunately, in the case of laying hens, this is not true. We have an excellent history of how our birds have improved over the past decade (Table 1), and a fair idea of what can be expected in future breeding programmes used by the primary breeding companies. Our understanding is that the requirements for energy and protein per unit of output have remained unchanged and that...

I. INTRODUCTION Phytic acid salts or phytate constitutes up to 70 % of the phosphorous (P) stored in cereal grains and oilseed meals and this P is poorly utilized by poultry due to limited endogenous phytase secretion (Ravindran, 1995). Therefore, exogenous phytase is routinely used in poultry feed worldwide to address the issue of optimizing P utilization and mitigating the negative impact of dietary phytate on bioavailability of other nutrients i.e. minerals and AA...

1 Introduction Copper (Cu) is a crucial trace element in animals; however, it cannot be stored in the body, thus, a regular dietary supplement is required. In addition, feed ingredients are commonly deficient in Cu; hence, the commercial diet should provide the essential amount of Cu in a biologically dynamic form, which depends on the physical and chemical properties of the form of the supplement in which the Cu is given in the diet [1]. Cu sulphate (CuSO 4 ) is...

INTRODUCTION Phytase is commonly supplemented in laying hen diets to increase the bioavailability of P and Ca. Dietary phytase supplementation increases Ca and P digestibility (Beutler, 2009), egg production, BW, eggshell quality, and bone quality in egg-laying hens (Hughes et al., 2009; Pelicia et al., 2009) and increases blood myo-inositol concentration in broilers (Sommerfeld et al., 2018). The effects of phytase in diets reduced in available P (avP) and Ca on laying...

Components of Gut Health The intestine is a complex organ that comprises regions with distinct structural and physiological functions specialized in digestion and nutrient absorption. Simultaneously, the gut represents the primary contact site with foreign antigens and pathogens that can enter, reside and disseminate to the internal organs. For this reason, the gut harbors the majority of immune cells, referred to as gut-associated lymphoid tissues, when compared to other tissues....
