Live yeast in swine nutrition
Considering the beneficial effects on intestinal microbial balance, dietary administration of probiotics such are live yeasts are reported to relieve the stress of sows in gestation and lactation. Live yeasts are known for many beneficial health effects including antioxidant defense mechanisms, thereby ameliorating oxidative stress. Live yeasts are mostly active dry yeasts (typically Saccharomyces cerevisiae). Its effects depend on a combination of strain specificity and quantity of live yeast (CFU) surviving and performing in the right part of the gastro intestinal tract. In this sense, a live yeast that has been selected for high oxygen scavenging potential in addition to a product with a higher CFU concentration would be more beneficial as it would need less inclusion to achieve the target CFU number.
The benefit of adding a live yeast is the ability to scavenge, or remove, oxygen. A high level of colony-forming units (CFU) per gram may be measured through redox potential (Eh), which is key to providing the best possibility for live yeast to change and optimize the gut environment through the removal of oxygen concentration. The more negative the Eh value, the greater the potential to scavenge oxygen. During ingestion of feed and water or under stress, oxygen concentration is higher due to increased oxygen ingestion and oxygen emission from the epithelial cells, respectively. Feeding live yeast maintains a lower Eh, even at times of feeding. Based on recent work in piglets, adding a live yeast was able to improve the redox potential.

1. Introduction Mycotoxins are a persistent global issue and cause significant production losses in pigbreeding. Furthermore, recent climate change is responsible for the changing spectrum of mycotoxins in food and feed [1,2]. Despite improvements in agricultural and production practices, mycotoxin contamination cannot be prevented, and contaminants are virtually ubiquitous at certain concentrations in the average human and animal diet. Whereas aflatoxins can be easily removed...

Introduction: Saccharomyces cerevisiae boulardii is a probiotic yeast with an established history of use for the prevention and/or treatment of diarrhoea and chronic inflammatory disease in human medicine. More recently, S. boulardii has also been used in the pig industry to increase performance and reduce pathogen burden during vulnerable early life stages such as post-farrowing and weaning. Recent advances in DNA sequencing technology are now able to understand the host...

Introduction: The piglets TGI is not yet completely developed after weaning for solid diet digestion and absorption, so different ingredients are used to minimize these problems, improve feed intake and body weight gain during nursery phase. Yeast has been used as an important source of nucleotides, proteins, amino acids, MOS and β-glucans. Based on this, the aim of this study was to evaluate the supplementation of yeast as a source of nucleotides in piglet’s diet...

Safglucan® – Mitigating the negative impact of Lawsonia intracellularis on pig performance and intestinal wellbeing. Phileo by Lesaffre has shown that feeding its yeast (1.3)(1.6) beta-glucan, Safglucan®, can help pigs cope better with the negative effect of enteric disorders caused by Lawsonia intracellularis. This is a new (patent pending) application for Safglucan® to help the pork industry achieve profitable production while also reducing antimicrobial...

What is the incentive for the EU ban? The EU ban entails the use of high levels of ZnO (known as veterinary levels), which can be defined as levels above 150 parts per million (ppm). High levels of ZnO increase the risk of heavy metal accumulation in the environment and the potential for antimicrobial resistance. We should not forget that zinc is an essential part of swine diets, at nutritional levels (below 100ppm). Zinc is needed for various enzyme to work properly and it...

What are consequences of the ban for farmers? The ban will increase the risk for the development of digestive problems in piglets after weaning. Most pig producers already have very high standards of hygiene and management practices, but the ZnO ban means we have to even better take care of these things. This could mean that we have to re-evaluate for example the state of the weaning facilities. Are the feeders and drinkers still ok? It is also important to have the right pig...

Are we prepared to remove ZnO from piglet diets? A survey done by Farmers Weekly and Elanco showed that that one-third of pig farmers in the UK are still routinely using zinc oxide in pigs after weaning, and 60% have no plan in place for when it is banned in 2022. Minimising problems is all about good preparation and know the solutions that you can use to limit the negative effects of removing ZnO (such as increased costs, low feed intakes, gut health issues).
