Introduction Trace minerals exist in cells and tissues of the body in a variety of chemical combinations and characteristic concentrations, depending on the trace mineral consumed and the tissue in which the trace mineral is metabolized (McDowell, 1992; Underwood and Suttle, 1999). Concentrations of trace minerals must be maintained within narrow limits in a cell (McDowell, 1989, 1992; Underwood and Suttle, 1999). Trace mineral deficiencies, toxicities, and imbalances require the...
Introduction Animal production faces serious challenges, having to feed a growing population while dealing with increased competition for land, climate change and having to take a more sustainable approach. Sustainable agriculture requires us to meet society’s present needs without compromising the ability for current, or future generations, to meet their needs. The effectiveness by which an animal is capable to transform feed biomass into animal products determines the amount...
Introduction The global agricultural sector, including associated land-use changes, was responsible for emitting 10.6 gigatons (Gt) of carbon dioxide equivalent (CO 2 e), contributing considerably to the overall 53 Gt CO 2 e of global greenhouse gas (GHG) emissions (FAO, 2023). In the United States, the agriculture sector contributed 0.59 Gt CO 2 e in 2022, representing 9.36% of the nation's GHG emissions. This marked a 7.7% increase from 1990 levels...
Introduction With the increasing demand for animal protein projected for the next decades as world’s population increases, the perceived antagonism between intensive animal production and climate change will intensify. It is estimated that livestock agriculture accounts for 14% of total CO2 emissions of which 1.4% can be attributed to pig production (FAO, 2020, IPCC, 2019 and 2022). Social pressure, policy making, carbon tax and sustainable financial investing will necessitate...
INTRODUCTION Nutrient requirement for any ingredient is defined as the amount of that nutrient which must be supplied in the diet to meet the needs of the normal health of an animal in an environment compatible with good health. It can also be said to be the amount of a given nutrient required by the animal to maximize performance. Formulation of a balanced diet is fundamental to economical poultry production, and this process depends on knowledge of nutrient requirements of poultry...

Abstract. The concept of a "feed enzyme matrix" has become widespread over the past 10 years. It is used to quantify the increase in nutrient utilization of a feed by the action of feed enzymes.The factors that change the matrix values of enzymes are given. Due to the impossibility of substantiating stable values of matrices, in official instructions the values of matrices are virtual, therefore, they are not subject to control. In the instructions for the use of enzyme preparations approved...
Increasing prices and low availability of common feed raw materials resulted in the use of alternative ingredients in animal production. These ingredients are often characterised by a high amount of soluble fibre resulting in lower performance and intestinal health issues that limits their inclusion rate in the diet. Bacillus amyloliquefaciens CECT 5940 (Ba) is a probiotic that can produce various metabolites and enzymes relieving the negative effects of soluble fiber and therefore it allows...

"Trace minerals are nutritional elements added to production and companion animal diets in tiny quantities. They are essential for structural, physiological, catalytic, and regulatory functions in animals, making their inclusion in diets crucial for various reasons. Natural diets may not provide sufficient amounts of specific minerals to meet animal needs, the minerals in the feed may not be in a form that is easily absorbed, or anti-nutritional factors might decrease the proportion of...

Copper (Cu) is a vital element involved in cellular metabolism and enzyme systems. At levels greater than nutritional requirements, dietary Cu addition enhances growth performance as a growth promoter (Pesti and Bakalii, 1996). Copper dosing at levels up to 250 mg/kg feed has been shown to improve intestinal structure and function, and alter the intestinal microbiota profile (Di Giancamillo et al., 2018). However, a high level of copper in the sulphate form (CuSO 4 ) which is...
Impact of Trace Mineral Status on Biological Function: The nutritional status of animals is an indicator of their productivity and reproductive capabilities. In tropical countries like India, mineral imbalances or deficiencies are prevalent . (Mc Dowell et a l., 1993) . Livestock in India typically rely on grazing and receive minimal or no mineral supplementation, apart from common salt. (Garg et al ., 2005) . Additionally, the mineral content of locally...
I. INTRODUCTION Currently, the majority of feed used in the production of broilers is fed in pelleted or crumbled form. One of the major issues in the manufacture of pellets is the application of high conditioning temperatures. The need to reduce potential levels of feed-borne pathogens such as salmonella and campylobacter for feed safety and to achieve high pellet quality has led to the application of relatively high (between 80 and 90 ºC) conditioning temperatures during...
A growing population that we have to feed, by 2050 approximately 9 billion inhabitants. Climate change, global warming, atmospheric phenomena (hurricanes, floods, prolonged drought that drastically affect grain harvests). Overfishing in our seas that is decimating and extinct some marine species. ...
"A Critical Perspective on Statistical Issues in Estimating Nutrient Bioavailability in Animal Bioassays" reviews the complexities and potential errors in calculating relative bioavailability values (RBV) for nutrients in animal feed, especially using the slope-ratio method. This method, frequently applied in poultry nutrition research, often lacks rigorous statistical validations, leading to unreliable RBV results that can impact nutritional decisions. The review highlights issues like the...
