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.

Introduction An essential component of the overall health and well-being of the broiler chicken is ensuring that mineral nutrition, in all its facets, is adequate. As growth rates increase and production systems intensify, mineral nutrition will become more critical. Most minerals in the bird occur in the skeleton, so skeletal integrity is perhaps the critical issue. However, minerals play a role in all aspects of metabolism, both as cofactors of enzymes and controlling free...

Back in 2019, Shell Egg Academy (SEA) was born out of conversations with egg companies about the training and education needs they have for their managers and employees.
Together with a planning team from various egg companies, academia and regulatory agency folks, we have learned a lot about how to structure our courses. It is our commitment that SEA continues to be the place to get up to speed on all of the latest information and training on egg production and egg food...

1. Introduction The use of insects in animal nutrition is a promising alternative in order to obtain a sustainable protein source to feed the world. Considering the current challenges of overpopulation and feed supply for animals and humans, new feed ingredients are needed to provide a secure food production chain in the future [1]. Edible insects have been shown to be highly nutritious and healthy food sources (rich in protein and fat), with beneficial nutraceutical...

INTRODUCTION Large variations exist in the literature on the recommended Ca and P dietary requirement for laying hens 1 . The Ca requirement was reduced from a previous suggested intake of 3.75 2 to 3.25 g h −1 day −1 by NRC 3 after decades of consistently increasing the Ca intake requirement. The available P or non-phytate P (NPP) requirement for commercial layers was also reduced to 250 mg h −1 ...

Introduction Water is considered an essential nutrient as it is involved in every metabolic function of the body. It represents about 70% of body weight, and its body content decreases per weight unit as the animal ages, despite the increase in water consumption. Water turnover rate is high compared to that of other compounds (Leeson & Summers, 1997). Water intake is a determinant of broiler performance, as it influences bird health and welfare status (Brooks, 1994;...

One of the greatest challenges to production facing poultry farmers in India is heat stress and the strain that it causes to the bird. Climatic conditions in India are such there is intense radiant energy for an extended period of time. Poultry create a large quantity of metabolic heat and accumulate additional heat from radiant energy. Heat production and accumulation, coupled with compromised cooling capability because of environmental conditions, causes heat load in the bird to increase...

The eggshell consists of 95% calcium carbonate, the necessary calcium is obtained from the feed or the bones of the layer. Calcium is absorbed in the intestine and its absorption and metabolism are regulated by vitamin D. To avoid related problems, regular supplementation with calcium and vitamin D3 is recommended. PlusVet Animal Health developed PhytoMax © which is a combination of vitamins, calcium in chelate form, microminerals and essential oils to add to the drinking water of layers and...

INTRODUCTION Genetic selection for higher growth rate, and providing balanced diet and superior health care measures led to a higher body weight in commercial broilers. The birds that are being reared in open-sided poultry houses may lead to stress due to constant dynamic variations in temperature and humidity in the environment, which causes adverse effects on performance (Niu et al., 2009), meat quality and immune responses (Thompson and Scott, 1970). Further, heat causes a...

Copper (Cu) has been widely used at pharmacological levels (e.g., 125 ppm) as growth promoter in poultry. However, the mechanism by which high levels of Cu promote growth remains to be determined. It is commonly recognized that Cu exerts anti-microbial effect in the gut but there is not much direct and consistent data showing that Cu alters the population of bacterial species in birds. And copper can maintain proper body functions and obtain the optimal growth performance of poultry (Banks...

During heat stress, birds strive to regulate their body temperature by panting, increasing their respiration rate from a normal rate of 25 breaths per minute to a maximum of 250 breathes. As birds pant, they eliminate excessive amounts of carbon dioxide (CO2), which leads to low concentrations of carbonic acid and...

Zinc (Zn), as an essential trace element, is a common feed additive for food producing animals. Zn is supplemented in either an inorganic or organic form. Literature suggests inconsistency among both sources regarding trace mineral availability and influence on animal performance, but organic trace minerals are considered to be advantageous (Schlegel et al., 2013). Between organic trace minerals, the chemical bond is the main difference. While mono-glycinates are complexes with one amino...

Phytase supplementation of broiler diets can improve energy, amino acid, calcium (Ca) and phosphorus (P) utilization. Both fungal- and bacterial-derived phytases are commonly added to broiler diets. Phytases from different sources and even from the same source can have different pH optima, heat stability, and catalytic properties (Dersjant-Li et al, 2015). Furthermore, when different microbial phytases are included in diets, their efficacy in vivo can vary in comparison to their assayed...

Understanding the dynamics of calcium (Ca) and phosphorus (P) metabolism is an important consideration when evaluating the requirements for both nutrients. Much more is known about the control of Ca than P metabolism (Li et al., 2017). Calcium elimination from the body is primarily through faeces, both unabsorbed dietary Ca and endogenous Ca. Kidney Ca elimination is controlled by endocrine factors and to a lesser extent by dietary Ca. In practical terms, dietary Ca may be available but not...
