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.

Background and objectives The recent EU ban on therapeutic levels of zinc in animal diets has led to concern regarding potential performance losses and animal welfare. Potential alternatives such as organic acids have been shown to be beneficial in reducing gram negative bacterial and promote digestibility (Canibe et al., 2001; Mroz, 2005). These properties may also help in the replacement of zinc oxide (Roselli et al., 2005). The aim of the study was to evaluate two acid based...

Background and objectives Wheat bran (WB) has been demonstrated to promote intestinal health and improve piglet performance (Molist et al. 2011 & 2012). One proposed mechanism for this effect is that WB inhibits the attachment of bacteria, specifically enterotoxigenic Escherichia coli (ETEC) K88, to the intestine (Gonzaláz-Ortiz et al. 2014) thereby reducing the risk of ETEC-K88 induced diarrhoea. The objective of this trial was to determine whether WB inclusion...

Background and objectives
Altering feed composition can be an alternative to the therapeutic usage of zinc oxide (ZnO) to maintain piglet performance and to reduce post-weaning diarrhea. Supplementing the diet with the right functional fiber source is one way to replace ZnO. Inert fiber sources may improve the gut health of weaned pigs by modulating the activity of intestinal microbiota (Molist et al., 2011). The aim of the study was to investigate the effect...

Background and objectives
In a context of reduction of antibiotics and zinc oxide (ZnO), alternatives are needed to maintain animal health and growth performance. In a study conducted in post-weaning piglets, we have demonstrated positive effects of a supplementation with Saccharomyces cerevisiae var. boulardii CNCM I-1079 (SB, 2x109 CFU/kg). Despite a removal of antibiotics and ZnO after 11 days post-weaning, SB supplemented piglets displayed the same average daily...

Background and objectives The potentiated ZnO source HiZox® (Animine, France) was shown to be advantageous for piglet performances (Cho et al. 2015, Morales et al. 2012, Raquipo et al. 2017). More specifically, we demonstrated that the potentiated ZnO source when added to a barley-cornwheat and SBM diet, reduced digesta Enterobacteriaceae numbers and improved gut integrity, albeit similar or better, depending on the dosage, to the effects of pharmacological dosage of...

Background Several international and Danish trials have shown that lowering protein levels in weaner diets can reduce post-weaning diarrhea. Results are conflicting as to the effect on productivity, probably depending on the levels of limiting amino acids in the diets. The aim of this trial was to test different protein strategies to reduce diarrhea without adversely affecting productivity. Methods The trial was conducted at SEGES research...

In the pig industry, the use of high levels of zinc oxide (ZnO) is used for prevention and treatment of diarrhoea in weaning piglets, but the mechanism of action of Zinc has not yet been known. Some studies tested some hypothesis as WANG ET AL that demonstrated the ZnO alters the expression of intestinal proteins that are related to the regulation of oxidative stress, cell proliferation and apoptosis in weanling piglets 1 . In light of these studies, this work intends to propose a...

Background
The Danish pig production industry is characterized by high levels of health and productivity. In 2018, the Danish production reached 32.5 million pigs, of which 18 million were slaughtered in Denmark, while 14 million piglets were exported to mainly Germany and Poland for further fattening. The export of growing pigs began in 2004 and the demand for Danish weaners has increased annually. Because of the large export of pork and weaners, Danish...

Enterotoxigenic E. coli (ETEC) can cause significant digestive disorders in postweaning piglets. Modern strategies are searched, how to replace antibiotics and ZnO as a feed additives. Some studies suggested that live yeasts Saccharomyces cerevisiae may help protect piglets against an ETEC infection. Probiotics, including live yeast and lactic acid bacteria cultures, have been reported to improve performance of weaned piglets. Piglets fed milk replacer supplemented with...

Introduction Animal diets based on corn and soybean meal are very deficient in available phosphorus (P) to the point that supplementation is necessary using sources of high P availability. Dicalcium phosphate is commonly used as a source of supplemental P. Commercial dicalcium phosphate is a mixture of varying amounts of monocalcium and dicalcium phosphates, phosphoric acid, calcium carbonate, and impurities (Lima et al., 1995). Some animal production technicians point out that...
