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.
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....

Background Biofortifications of chicken with bioactive nutrients such as DHA and calcidiol [25(OH)D3] have been viewed as an effective strategy to produce health-promoting meat for human consumption [1, 2]. Relatively low to moderate inclusion levels of calcidiol (1600 to 2800 IU/kg diet) [3, 4] and DHA-rich microalgal biomass or oil (0.55 to 2.55 g DHA/kg diet) [5–7] in broiler diets caused no negative effects on growth performance, lipid profile of tissues, or...

What really matters in feed phosphates? The quality of a feed phosphate is determined by the total phosphorus content and its absorbability. In other words, the total amount of P which is available to be used (absorbed) by the animal. Although current formulation systems assume a 100% absorbability for all the inorganic feed phosphates, current research demonstrated differences in absorbability of P content among different types of phosphate. Moreover, significant differences in...
