Yeast Special

MycotoxinLive yeast is increasingly used in animal nutrition. Proven results in ruminant nutrition are documented and results in pigs and poultry also come through. Yeasts vary greatly, not only in their unique genetic strains, but also in the way they are produced, cultured, used and the extent to which they can be beneficial.



Live yeast in breeding animal diets helps offspring

It is critical that newborn animals rapidly get colostrum after birth, to provide immunity as well as much-needed nutrients and to ensure a good start in life. In addition to good farm practices and feed formulation, the addition of live yeast to the feed of the mother has positive short as well as long-term effects on suckling animals.

 Maintaining rumen health in wake of poor forage quality

Weather conditions over summer determine to a high degree the quality of silage in winter. Wet weather can lead to low quality silage, in turn a potential cause of Sub Acute Ruminal Acidosis in dairy cows. Managing silage quality therefore is paramount.

 Each yeast product requires its own approach

Optimal yeast production could be compared to the optimal production of food animals. Natural and genetic selection, fine-tuned nutrition and growing environment all play critical roles in order to get the organism that is intended. Lallemand Animal Nutrition walks All About Feed through one of its numerous yeast plants.

Application of yeast cell wall in swine

As a major component of yeast, yeast cell wall has various effects, like improving nonspecific immunity, increasing resistance to infection, adsorbing mycotoxins and regulating the micro-environment of an animal’s digestive tract. In recent years, the use of commercial yeast cell wall has received more attention and has become accepted widely, which is attributed to advantages of naturality, non-residual and no drug resistance.

Yeast cells and β-glucans – Multibiotic factors for successful animal nutrition

Yeast cells can be used in many different ways in animal production. Not only the entire yeast cells can be fed, but so can the cell walls or even extracts of cell walls. This article dives into the effects of all different options for use in pigs.

The big quest: How does live yeast work in animal feed?

For more than 30 years, animal nutritionists have been puzzled as to why yeast cultures appear to be beneficial for farm livestock production. Slowly but surely, the veil has been lifted. Yeast’s ability to take up oxygen is what does the trick.

Use of live yeast in animal diets: What do we know?

Much research has been carried out about the use of live yeast in animal production. For each animal species, effects can differ. What is the state of research for several animal species? All About Feed dives into the modes of action for cattle, horses, pigs and companion animals.
