Virbac Selpor 2.5L Pour-On Selenium Supplement for Cattle

Keep your herd in peak condition with Virbac Selpor 2.5L, a powerful pour-on selenium supplement designed specifically for beef and dairy cattle. Available now at Farmco, your trusted local farm supply store, Selpor offers an easy, effective way to manage selenium deficiencies that can impact herd health and performance.

Why Use Selpor?

Selenium plays a vital role in supporting immune function, fertility, and growth in cattle. Deficiencies can lead to poor weight gain, increased susceptibility to disease, and reproductive challenges. Selpor helps prevent these issues by delivering selenium directly through the skin in a convenient pour-on formulation—ideal for farmers looking for fast, stress-free supplementation.

Selpor is recommended for use before key stress periods, such as calving, weaning, or transport. It’s also perfect for long-term maintenance, ensuring your cattle receive consistent selenium support across the production cycle.

Selpor 2.5L is Fast-Acting, and has No Withholding

One of Selpor’s standout features is its rapid action. The topical application absorbs quickly through the skin, distributing selenium throughout the animal’s system. Even better, Selpor comes with nil withholding periods for meat and milk, so you won’t need to delay your production schedule. It also has nil Export Slaughter Interval (ESI)—an added bonus for producers targeting international markets.

Simple Dosage & Application

To use, apply 2mL per 50kg bodyweight, up to a maximum of 20mL per adult animal. Always shake well before use. The 2.5L pack is ideal for treating multiple animals with ease and efficiency.
