Minerals in poultry nutrition
Welcome to the page about Minerals in poultry nutrition of Engormix; a source of knowledge on Minerals in poultry nutrition.
Hydroxychloride trace minerals (HTM) have covalent bonds and thus are less reactive both in the feed and in the digestive tract compared to inorganic trace minerals, which contain ionic bonds (ITM) such as sulphate forms. Therefore, HTM may have higher bioavailability than ITM. This study aimed to evaluate the effects of replacing sulphate forms of zinc (ZnSO 4 ), manganese (MnSO4) and copper (CuSO 4 ) (ITM) with HTM sources on tibia bone traits and mineral content in...

Feed plays a fundamental role in the growth and development of farm animals, as a balanced diet is essential for their health and determine an optimal performance. One of the most important aspects in the production of animal feed is the presentation of the feed, as it has a direct influence on feed consumption and...

I. Introduction Poultry diets are currently formulated based on total calcium (Ca) and available phosphorus, with a ratio of 2:1 being maintained between them. For a number of reasons, there is increasing interest in shifting the formulations based on digestible Ca and digestible P. To enable this move, information is required of the requirements of digestible Ca and digestible P. A recent study at our laboratory (David et al., 2021) determined the standardised ileal digestible (SID)...

Trace minerals are often supplied in the forms of inorganic salts such as sulphates into poultry feed to meet the requirements. The ionic bonds in inorganic salts of minerals are very weak allowing the metal ion to disassociate once in contact with water, binding up diet antagonists such as other minerals, vitamins, and enzymes. To mitigate these negative effects technologies such as organic minerals or mineral complexes, which are less reactive, are used. In hydroxychloride minerals (Hyd)...

As in commercial broiler chicken production, broiler breeder performance depends upon adequate dietary trace minerals, including zinc (Zn), manganese (Mn), and copper (Cu). Broiler breeder diets currently used in the industry contain levels of the inorganic forms of these minerals with generous safety margins. Researchers now report that combining inorganic sources of Zn, Mn, and Cu with organic hydroxy analog of methionine (HMTBa) forms in breeder hen...

Summary This study was conducted to test the efficacy of phytase in low phosphorus and calcium diets in the late production cycle for maintaining the productivity, eggshell and bone quality of hens fed low phosphorus and calcium. Problem Exogenous phytase supplementation has become a standard practice for poultry diets to liberate available phosphorus and reduce excretion of phosphorus in manure. Many studies showed that phytase supplementation increased egg...

About the study Phytase supplementation has become a standard practice for poultry diets to enhance phosphorus (P) utilization and subsequently reduce P excretion. Previous phytase studies on hen performance, eggshell and bone quality have been done over short durations and using hens of varying ages. The knowledge gap is that there are no long-term phytase studies covering the rearing period through the end of production cycle. The objective of this study was to...

Enzyme supplements are used widely in poultry diets in an attempt to improve poultry performance, feed consumption, and also minimized environmental pollutions due to the reduced output of excreta 1 . Different enzyme supplements have been developed with respect to their target substrates in feed ingredients. Exogenous xylanase is an example of an enzyme supplement to improve nutritional factors by efficiently decomposing the non-starch polysaccharides (NSP) 2 ,...

Summary The short-term study was conducted to test the effects of phytase supplementation in laying hen diets during peak production on bone characteristics as well as phosphorus (P) and calcium (Ca) digestibility. Problem A large portion of dietary phosphorus is not utilized by laying hens and is excreted in feces, which leads to phosphorus pollution in the environment. Adding inorganic phosphorus to poultry diets has also become much more expensive. Phytase...

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...

Soybean meal (SBM) and canola meal (CM) are two plant-based protein sources which contain reasonable amounts (2.9 and 6.8 g/kg, respectively) of calcium (Ca). Currently, no published values are available for the Ca digestibility in SBM and limited studies (Anwar et al., 2018; Moss et al., 2018) are available for the Ca digestibility in CM. Microbial phytases are now routinely added in poultry diets to improve the bioavailability of phosphorus (P) bound to phytate (myo-inositol hexaphosphate)...

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...
