Biochem Expands Its Popular RumiPro® Product Line.

RumiPro® Wean, the latest product to join the line of products developed for ruminants, supports calves as they transition to weaning. 

Lohne, November 2025. Biochem announces the newest addition to its RumiPro® product line: RumiPro® Wean. This breakthrough solution is designed to make the weaning process smoother, safer, and more successful. With its unique blend of proven ingredients, RumiPro® Wean promotes better rumen development, supports a resilient immune system, and helps to mitigate growth slumps related to weaning. 

“Many farms lose the hard-earned progress they achieved during the milk-feeding phase when weaning,” said Miriam Deppe, Product Manager at Biochem. “RumiPro® Wean is specifically designed to prevent those setbacks and ensure a smooth transition to solid feed for calves without compromising their growth or health.” 

Weaning is one of the most critical phases of calf rearing. It is characterized by many stressors, including nutritional, environmental, and social factors. Despite its importance, this phase is often overlooked. Growth slumps occur on almost every farm during this time due to suboptimal nutrition, decreased nutrient intake, increased energy consumption, and higher rates of disease. In fact, many farms experience a four- to eight-week standstill during this phase, during which any gains made during the milk-feeding phase are lost. 

In addition to the stress of weaning, calves are more susceptible to mycotoxin contamination, which can result in reduced feed intake and growth and suboptimal rumen development. Calf feed often poses a high risk of mycotoxin contamination because it contains large amounts of grain, corn, or soy to provide energy. This makes targeted intervention essential to reduce the early impact of mycotoxins on calf health. 

RumiPro® Wean is a unique formulation that combines carefully selected functional ingredients, including proven ingredients like TechnoYeast, E.C.O.Trace® Zinc, and B.I.O.Tox® Active Core to support rumen development, boost vitality, and enhance the resilience of calves. RumiPro® Wean establishes a solid foundation for post-weaning growth and long-term herd productivity. 

“We know that young calves are especially vulnerable to feed-borne mycotoxins,” Deppe added. “By integrating an effective mycotoxin binder into RumiPro® Wean, we are giving farmers a tool that not only protects animal health but also safeguards long-term performance and profitability.” 

RumiPro® Wean is a pelleted dietary feed supplement available in 20 kg bags for calves, kids, and lambs.
