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.
Dr. Piotr Stanislawski shares his comments with Engormix members regarding the calculation of phosphorus and calcium, as well as other formulation issues....

The modern broiler chick spends 50% of its life in an embryonic state. It is therefore important to ensure that adequate nutrients are available to the developing embryo, which is completely reliant on the diet fed to the breeder hen. Consequently, the physiological status of the chick at hatching is greatly influenced by the nutrition of the breeder hen. The nutrient supply to the broiler breeder is a sum of the actual nutrient content of the diet and the quantity or volume of feed...

Yangzhou University scientists examine meat quality from every angle
Duck meat is prized for its delicate flavor and juicy texture, as well as its notable protein content, polyunsaturated fatty acids, vitamins and minerals. In fact, duck meat is rising in popularity, especially in China.
The challenge is to get ducks to market quickly without compromising meat quality. In China, which produces 85...

Phytate is a polyanionic molecule with the capacity to chelate Ca, forming mineral-phytate complexes. The presence of these complexes decreases the efficacy of phytase. Ca-phytate formation is dictated by molar ratios of the constituents, gastrointestinal pH and the concentration of dietary Ca relative to P (Sommerfeld et al., 2018). The hypothesis of this study was that a high dietary Ca to P ratio will reduce the ability of phytase to hydrolyze phytate, which will exacerbate necrotic...

Introduction: Due to the constant genetic evolution in both the production of broilers, nutritionists must constantly adapt their nutritional recommendations and feeding programs to maximize economic results at all times. These management and nutrition decisions must take into account: the animal (potential for growth), environmental conditions and the composition of the feed, which affect feed consumption and, consequently, the performance of birds. And economic...

A healthy chicken gut is essential for optimum digestibility, maximum nutrient absorption, immunity development and disease resistance. Disruption of gut integrity and imbalance of gut microbiota may have negative effects on feed conversion, productivity, and health of chicken. For the last few decades in poultry production, antibiotic growth promoters (AGPs) have been widely used in poultry diets to promote growth, improve feed efficiency and control dysbacteriosis and enteric...

INTRODUCTION Hemp ( Cannabis sativa L.) is an annual herbaceous plant belonging to the family Cannabinaceae 1 , traditionally grown for fiber and seed production. Whole hemp seed contains approximately 25% crude protein, 33-35% oil and 34% carbohydrate, in addition to a broad range of vitamins and minerals 2-4 . Hemp seed oil contains 75 to 80% polyunsaturated fatty acids (PUFA), including 60% linoleic acid and 17-19% α-linolenic acid...

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...

We have a layer poultry farm here in the philippines. 2 bldg. with a population of 9,400/bldg. The breed is lohman white. Age is between 20 - 28 weeks old with a production of 70% and 90%. The problem is our mortality is ranging from 10 - 15 heads per building per day. primary cause of death is prolapse and egg bound. we fed them with a high enery feeds, does the high energy feeds contributes to our chicken prolapse? Temperature is around 28 to 30degree celcius....

INTRODUCTION Vitamin D is a group of closely related compounds that have antirachitic activity. It has been estimated that nearly 50% of the United States population is at risk for vitamin D deficiency or insufficiency (Holick et al., 2011). Vitamin D 3 (D 3 ) deficiency can cause rickets in young children or increase the risk of osteoporosis and osteomalacia in adults (Holick, 2005). One approach to increase D 3 intake in a population without...

Choline- chemically known as 2-hydroxyethyl-trimethyl ammonium hydroxide andis referred as vitamin B4. It has recently been claimed as a rediscovered vitamin & performance promoter in poultry. The role of choline in the prevention of conditions suchas perosis and liver enlargement in chicks is already well known. Choline wasfirst isolated from ox bile ("chole" in Greek) in 1849. Its nutritional importancehas been recognized since 1930 and it is now a common dietary supplement forlivestock &...

INTRODUCTION In poultry, phosphorus (P) is an essential nutrient in metabolic processes and a component of nucleic acids, membrane phospholipids, and bones (Nie et al., 2013). Much effort has been made to increase P absorption in poultry to improve metabolic performance and reduce the environmental impact of phosphate (Pi) release from manure (Ahmadi and Rodehutscord, 2012; Letourneau-Montminy et al., 2013). Dietary P is absorbed in the small intestine by both passive and...

I. INTRODUCTION Dietary electrolyte balance (DEB) is defined by the interrelationship between sodium (Na + ), potassium (K + ) and chloride (Cl - ) where DEB = Na ++ K + -Cl - as mEq/kg and it plays an influential role in homeostasis of the body fluids. Borges et al. (2004) investigated DEB in two experiments and concluded that there was a quadratic effect on weight gain and feed conversion efficiency (FCE) when the DEB was...
