Minerals in swine nutrition
Minerals constitute a small percentage of swine diets, but their importance cannot be over-emphasized. Functions of minerals are extremely diverse, serving a variety of structural, metabolic, and regulatory functions in all body components. The mineral nutrition of pigs must be precise because adding excess minerals to the diet can be costly and cause toxicity while not providing enough minerals can result in deficiency and reduce productivity.
Minerals are classified into macrominerals and microminerals according to the amount required in the diet. Macrominerals or major minerals need to be supplied in larger amounts in swine diets, as is the case of calcium, phosphorus, sodium, chlorine, magnesium, and potassium. Microminerals or trace minerals need to be supplied in smaller amounts in swine diets, as is the case of zinc, copper, iron, manganese, iodine, and selenium. Chromium is also sometimes added to sow and finisher diets to improve performance.
Grains and oilseeds commonly used in swine diets are sources of macrominerals and trace minerals. However, the intrinsic minerals are often found at low concentration and availability in feedstuffs is questionable. Consequently, it is essential to balance the diets using supplemental mineral sources to meet the requirements.
Feed oxidation: What are the dangers? In pig diets, various sources of lipids are added to increase caloric density, provide essential fatty acids, improve feed palatability, improve pellet quality, and reduce dust (Keer et al., 2015). Some of the feed ingredients...

Introduction Trace minerals are essential elements in the maintenance of life for man and animal. However, what is not well understood or appreciated is how absorption and retention of these minerals can affect animal and human wellbeing, psychological status, health, and performance. While required in small amounts, just milligrams per day, trace minerals play critical roles as catalytic, regulatory, and structural components in multiple enzyme and...

The Pasteurellaceae family and its importance in pig production The Pasteurellaceae family is comprised of a group of Gram-negative coccobacilli bacteria that inhabit the respiratory, oral or gastrointestinal tracts of different animal species and can cause a wide range of infectious diseases in animals and humans. The family includes at least three important and well-characterized bacterial genera; namely, Pasteurella ,...

Background and objectives The therapeutic use of zinc oxide in high doses (e.g. 2,500 ppm Zn) has yet demonstrated beneficial effects on growth performance in piglets as well as the prevention of post-weaning diarrhea. The precise mode of action is still not known, but recent results indicate that the zinc-ions affect the gastrointestinal milieu and thus prevent the adhesion of pathogens. The objective of the current study was to investigate the effects of MiaTrace Zn, which...

Introduction Calcium (Ca) and phosphorus (P) are the two most abundant minerals in the body of the pig and are required for many important physiological functions (Oster et al., 2016). The vast majority of Ca—about 99%—is not only present in skeletal tissues (Nielson, 1972), but it also fulfills other very important roles involving blood clotting, nerve impulse transmission, muscle contractility, and fluid balance, to name a few (Pravina et al., 2013). In contrast,...

Vitamin A Affected by the excessive decline in the profits of live pigs and poultry farming, the market is mainly replenishing goods in a moderate amount for the time being. The current VA market is quoting USD43.50-46.50/kg, and the price is relatively stable. However, the temporary shortage of supply due to the suspension of production...

It is necessary that animals have a balanced intake of Feed and water.
Intake of water alongwith intake of Feed is an important indicator of the health of the animal.
Pigs and Poultry drink water twice the feed intake. Whereas Cattle drink water four to five times the feed intake. Hence, any deficiency in the feed can be supplemented by nutrients through water.
To improve the efficiency of animal functions, there are a number of nutritional supplements available but...

INTRODUCTION Research to determine the nutritional needs of most micronutrients for pigs was done mainly before the decade of 1990 and focused on avoiding nutritional deficiencies (Gaudré and Quiniou, 2009). Nutritional reference tables represent the theoretical basis for pig feed formulations indicating minimum requirement levels of supplementation (NRC, 2012) or values for best cost to benefit in feed formulations (Rostagno et al., 2017). However, considering...

INTRODUCTION Sows in transition from gestation to lactation are in a period of dramatic physiological change due to high nutrient demands of rapidly growing fetuses in utero, parturition, and lactation. These physiological changes require coordinated hormonal, nutritional, and management transitions to optimize piglet viability and postnatal growth (Theil, 2015). Inadequate preparation for these massive physiological changes could lead to increased stillbirth rate,...

1. Introduction
The increased awareness of potential negative effects of including antibiotic growth promoters in diets fed to pigs has resulted in an increased interest in producing pigs without using antibiotic growth promoters. However, by eliminating antibiotic growth promoters from diets fed to newly weaned pigs, disease problems may be increased and growth performance may be reduced. In contrast, removal of antibiotic growth promoters from diets fed to...

Introduction With intensive genetic selection for the prolificacy of sows, the swine industry is challenged with improving the piglet survival rate in connection with the increased litter size and decreased litter uniformity (Kim and Hansen, 2013). It is well known that maternal nutrition can have an influence on not only the development of fetal organ and tissue but also milk yield (Kim et al., 1999; McPherson et al., 2004; Farmer, 2018). Deficiency of maternal nutrients would...

Iron is an essential micronutrient for many biological processes, yet iron deficiency is considered the most prevalent micronutrient deficiency worldwide [1]. Though iron deficiency affects individuals of all age groups, women of childbearing age and children from birth to five years of age are at increased risk for...
