As the dairy industry continues to look for effective ways to support calf health without relying solely on antibiotics, natural alternatives like essential oils are gaining attention. One essential oil in particular, oregano oil, has been shown to provide health and performance benefits to young calves. Previously considered a niche product, oregano oil is now being used more commonly in calf-rearing programs. In this article, we will discuss how oregano oil can help improve calf health and performance, and what to consider before adding it to your calf program.

Health
The largest benefit of oregano oil is its ability to support the calf’s immune system by reducing harmful bacteria in the gut. The early weeks of a calf’s life are full of challenges, including exposure to bacteria that can cause digestive problems like scours. The compounds in oregano oil, primarily carvacrol and thymol, have natural antibacterial and anti-inflammatory properties. These compounds help disrupt the protective layers (biofilms) that harmful bacteria form in the gut making it easier for the calf’s immune system to fight them off.

Research has demonstrated that oregano oil has been linked to a reduction in diarrhea and improved overall gut health in pre-ruminant calves. Calves with a healthier digestive system are better able to absorb nutrients, which in turn supports immune development and helps reduce the impact of illness.

Performance
In addition to promoting gut health, oregano oil can have a positive effect on calf performance. Producers who use oregano oil often report improved appetite, increased starter intake, and better average daily gain (ADG). This increase in performance can be attributed to improved calf health and better absorption of nutrients.

A healthier gut allows calves to get more out of the nutrients they consume. In operations where oregano oil is fed consistently, calves have been observed to reach weaning weights faster and with fewer setbacks. Faster growing, healthier calves leads to reduced labor cost which has become a constant struggle for producers.

Even though the research on oregano oil is still emerging, current findings and on-farm experiences suggest it can play a useful role in supporting calf performance when included as part of a larger health and nutrition strategy.

Summit Pack
Oregano oil can be administered in several ways, including through milk replacer, electrolytes, or mixing into starter feed. Some calves may initially be sensitive to the strong flavor of oregano oil, so well-formulated blends can help ensure calves continue to consume feed and milk normally. Management when initially introducing milk replacer or other products containing oregano is vital to ensure a smooth transition. Summit pack is an Esmilco Inc. exclusive additive that contains oregano along with other immunes boosters that can be included in your milk replacer. It is designed specifically to enhance the intestinal barrier to protect your calf from challenges throughout it’s first couple months of life.

Oregano oil is one of many additives offered by Esmilco to boost your calf’s immune system for better health and performance. Check with your Esmilco representative to see how our summit pack and oregano oil can help your calves be their best!
