Live yeasts are attributed a wide range of positive effects in dairy cattle nutrition, from stabilising the rumen all the way to improving milk yield. Even under heat stress, the use of live yeast can have beneficial effects. In this article we explain how! <\/p>\n

Is yeast just yeast, or are there differences?<\/h3>\n

jbs offers a live yeast product that forms small beads through a special drying process. During this process, the living yeast cells are coated with a layer of inactive yeast. This is important because it protects the live yeast from air, moisture and fermentation acids, ensuring it arrives active in the rumen instead of already becoming active on the feed bunk. <\/p>\n

What makes our products with live yeast special?<\/h3>\n

The inactive and active yeast components in orgacell sc\u00ae<\/a> have positive effects on the rumen. Inactive yeast contains trace elements and B vitamins and has a positive influence on the microbial flora in the digestive tract. Components of the yeast cell wall can bind pathogens and stimulate the animal\u2019s immune system. <\/p>\n

How does live yeast affect the rumen?<\/h3>\n

A well-functioning rumen is the basic requirement for a healthy, productive and fertile cow. The rumen is often described as the \u201cengine of the cow\u201d. We cannot see inside the rumen directly, but scientists can. They have shown that live yeast helps ferment oxygen in the rumen, which is harmful to rumen microorganisms. It also helps stabilise rumen pH and reduces acid formation. Existing acids are broken down faster, protecting fibre-digesting bacteria, which are sensitive to low pH levels. Too much acidity also damages the rumen lining \u2013 you can only see that at the slaughterhouse. But if cows start licking their backs more frequently around two hours after feeding, it can be a sign of rumen discomfort caused by excess acid. <\/p>\n

Live yeast cannot multiply in the rumen (it is simply not the right environment), so it must be fed daily. What might sound like a disadvantage is actually an advantage: nothing can go wrong, because the yeast cannot overgrow. There is also no upper limit for feeding levels anymore. <\/p>\n

Are your cows suffering from heat stress?<\/h3>\n

Live yeast is the solution!<\/strong><\/p>\n

Feeding protected fats to secure energy supply is a common practice, but it only provides partial relief. These fats do not contribute to rumen function, and heat production in the cow remains high, even if fibre intake is reduced. In addition, this can easily lead to rumen acidosis. Live yeast stabilises rumen pH and improves fibre digestion. This helps maintain feed intake and reduces heat stress. You can see this in cows that eat more and show less panting. <\/p>\n

Does live yeast affect feed intake? How does it support feed intake? <\/h3>\n

Yes \u2013 by improving feed digestibility, especially in critical phases, forage intake increases. Cows that eat more produce more and fall ill less often. Live yeast optimises rumen processes and promotes feed intake. It increases the number of fibre-digesting bacteria while reducing lactic acid\u2013producing bacteria. As a result, cows start eating again more quickly. An acidic rumen causes unpleasant symptoms that are alleviated through rumination and saliva production \u2013 provided the feed has good structure to stimulate chewing. <\/p>\n

Conclusion<\/h3>\n

The use of live yeast in cattle feeding stabilises the rumen, supports digestion by fermenting oxygen, and stabilises rumen pH. This reduces the risk of digestive disorders and improves health and performance, especially during stressful periods such as summer months. In the long term, live yeast can have a very positive impact on overall herd health. <\/p>\n

Good forage quality also has a major influence on your cows\u2019 performance.<\/h3>\n

A good silage that provides cows with plenty of energy and nutrients is an essential building block for having a healthy and high-performing herd. Sign up here<\/a> and we will get back to you with the jbs harvest package.<\/p>\n","protected":false},"excerpt":{"rendered":"
