Strip grazing essentially involves the abnormal increase in stocking density, on a relatively small area, for a relatively short period of time (with long rest periods between uses).
Strip grazing is accompanied by:
Supplementing trace minerals can play a major role in reducing the negative effect of stress and address optimal animal performance under these conditions.
Trace mineral and vitamin supplementation:
During conditions of stress and certain critical periods in the production cycle, the formation of Free Radicals or Reactive Oxygen species (ROS) increases (Figure 1). The production of free radicals is a process that occurs naturally on a daily basis in the animal's body. However, the uncontrolled production of free radicals may cause damage to cells within the body of animals.
Figure 1. Formation of harmful free radicals
Luckily, there is a system to counter balance the uncontrolled production and negative consequences of free radicals. This happens through the action of antioxidant enzymes. These enzymes are particularly trace mineral dependent, especially Zinc, Manganese, Copper and Selenium (Figure 2).
Figure 2. Role of trace minerals in free radical neutralization
When there is an imbalance between the formation of free radicals and the functioning of antioxidant enzymes, a condition arises that is called Oxidative Stress. (Its effect can be compared to the process of rusting of iron). During oxidative stress, body cells are damaged. This can lead to the cells' functioning being adversely affected and even lead to disease, cell death and cancer.
When does supplementation works the best:
The world wide proven Multimin range (contact your Virbac Technical Sales Advisor for advise on the most suitable version) and
ProVit A - synergism between Vit A and Zn as well as Vit E and Se is NB.
Supplement Multimin and ProVit A before critical times in the production cycle:
