shaft so that the side nearest the barrel is at the appropriate daily dose marking,
aligning the arrow on the plunger with the notch on the ring.

Stress (including high performance training and competition), feeding, management
and husbandry practices may be associated with the development of gastric
ulceration in horses. Individuals responsible for the well-being of horses should
consider reducing the ulcerogenic challenge by modifying husbandry practices to
achieve one or more of the following: reduced stress, reduced fasting, increased
intake of roughage and access to grazing.

product to animals:
As this product may cause hypersensitivity, avoid direct contact with skin and eyes.
