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.

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.

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.

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.

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.
