Deltanil is presented for use with the company's Farmpack and Flexibag dispensing system, which was awarded the 2014 PharmaPack Award for Innovative Packaging. Virbac says the system offers farmers a convenient approach to treatment, combining easy application with freedom of movement and the flexibility of a long stability period once the product is opened.

The Farmpack backpack holds a 2.5 litre Flexibag of Deltanil solution, sufficient for the treatment of 250 cattle.

The Flexibag is a flexible, multi-layered, multi-component bag designed to protect and preserve medication, giving Deltanil a two year proven stability period after opening. Unopened, Deltanil has a three year shelf life.

Virbac Product Manager for Large Animals Brigitte Goasduf MRCVS said: "External parasites are a year-round threat to dairy and beef herds and can have a significant economic impact on yields. With the launch of Deltanil, we are offering a new approach to product application, one which is ideally suited to the practical conditions on farm and which addresses the challenges often faced in using pour ons.

"We believe that Deltanil, with its zero milk withdrawal period for dairy cattle and sheep and innovative Farmpack and Flexibag dispensing system, sets a new standard for products of this type.

"Deltanil is based on deltamethrin, a tried and trusted parasiticide. It offers a convenient approach to administration with a 10ml dosage per cow, irrespective of weight, and is presented in two sizes - the 2.5 litre Flexibag and a 1litre dispensing bottle. The 1litre bottle offers a year's stability once opened. The dosage per sheep is 5ml, irrespective of weight, with a 2.5ml dosage for lambs."
