The human health benefits of dietary selenium (Se) and iron (Fe) are well established (Rayman, 1997; Kristensen et al., 2005). Meat and meat products are primary sources of dietary Se and iron for humans. Pork from Se and Fe supplemented pigs may provide an additional source of these nutrients. However, the effects of supplementation of Se and iron on their status in muscles and effects on pork quality are not clearly defined. This study examined the effects of dietary Se and Fe...

Background and objectives
Pharmacological levels of zinc oxide (ZnO) are widely used in the weaning pig diets to promote growth and prevent post-weaning diarrhea. This practice is not environmentally sustainable; therefore, an effective alternative is warranted to be investigated. The objective of this study is to evaluate supplementation of Zn as Zn methionine hydroxy analogue chelate (Zn-MHAC, MINTREX® Zn, Novus International Inc., St. Charles, MO, USA) at NRC...

The swine industry has made great strides in swine reproduction; most specifically in the areas of increased litter size, increased milk production and improvements in productivity traits. With such rapid growth and improvement in those areas, other areas are lacking because sows’ diets haven’t all been adjusted yet to account for the nutritional and physiological demands of increased productivity. In general, piglet birth weight has decreased due to larger litter sizes...

The trace minerals provide essential nutrients required for various metabolic functions such as growth, development, reproduction and immunity. Even moderate deficiency can adversely effect animal performance. Consequent to urbanization and introduction of exotic breed as well as crossbreeding programme in livestock production, the increasing trends toward confinement of livestock, without access to soil or adequate green forage, increases the importance of...

In 1817, selenium (Se) was isolated for the first time by Berzelius. At that time little was known about its biological function, until its nutritional requirement was revealed about 140 years later by Schwarz and Foltz in 1957...

To evaluate the available phosphorus in inorganic P supplements, relative bioavailability of P has been measured, and the values were compared with the values from pigs fed monosodium phosphate or monocalcium phosphate. Although only limited data for the bioavailability of calcium in inorganic supplements had been measured, it was assumed the availability of Ca in most Ca supplements was close to 100%. However, it was demonstrated that values for relative bioavailability of P are...

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...
