Dear AVR KUMAR , Thank you for your question. Actisaf works by supporting the rumen microbiota by improving the rumen reducing conditions. In high reference published studies it always led to significant increase in lactic acid utilizing bacteria which reduce lactic acid to propionate. Also we observe significant increase in fiber digesting bacteria and improvement of NDF and ADF rumen digestibi ...

Early-lactation dairy cows have high energy demand for milk production. Often the energy intake in this period is not enough to meet their requirements and the cows often face negative energy balance that may lead to metabolic disorders with long lasting negative effect on both productivity and health. To meet this increasing energy demand, we often formulate high energy diets with increased sta ...

Learn from Valentin Nenov, Global Species Manager Ruminants at Phileo Lesaffre Animal Care, how after the drought of 2018, Phileo can help you to get the maximum from the diet using Actisaf® in cows, during Eurotier 2018

Dear Dr. Nenov, greetings from Sofia! It was my great pleasure to see the video with you! I know an Actisaf as a feed additive and source of viable cells of a strain Saccharomyces cerevisiae which has sure potential to be efficacious in weaned piglets and sows. But, up to now, no or insufficient evidence was provided to conclude on the efficacy of the additive in dairy cows and cattle for fattenin ...

For the most part, most dairies include at least some supplemental or additive products in their feeding programs. We build diets starting with the forage base, using the best forages we can, and then add different feed and grain components to provide protein and energy. Once the main nutrients are provided, it is then common to “fill in the holes” of the nutrient profile. Next, we of ...

Feeding fat and fat products to dairy cows is common on most, if not all, dairies. Understanding how to properly feed fats and fat products is another story and seems to change daily. This is especially true as we work to understand the roles various fat components (fatty acids) play in the animal in terms of production (volume and components), health and reproduction. And while it may not be ne ...

On any given day, the typical dairyman loses count of the challenges he deals with. From labor to mechanical issues, to sick or downed cows and paying the feed bill, the list goes on, seemingly forever. One frequent challenge accounting for much of the drain on overall farm performance and profitability is lack of consistency. Consistency issues are pervasive throughout the typical dairy operatio ...

Ruminant nutrition is highly sophisticated. Immense research and application efforts have culminated in great successes. Today, we can satisfy with a relative high precision the nutritional needs of high producing dairy cows. Highly efficient genetic selection and improvement in overall management has resulted in a national average of ca. 10,000 kg of milk per year in USA. The 2012 USDA annual rep ...

Am a dairy farmer in Kenya -That is in Africa. The constraints of good fodder production the world over is under threat by among other things climate change and diminishing land sizes.Its hard to avoid the temptation of being the super farmer with a river of white gold.But I think we have done well in improving the breeds without a similar effort the other end to improve on fodder quality and farm ...
