| RABAR CALF VIGOR |
|
Powdered Milk Additive for Calves containing Bio-Mos |
||
| Calf Vigor is designed to protect calves from coccidiosis during
the milk or milk replacer feeding period until such time as they are
consuming adequate levels of meal which should also contain an
anti-coccidial such as Bovatec premix. Calf Vigor also promotes
immunity and maintenance of intestinal membranes which are the first
line of defence against infectious organisms and which may be
damaged during coccidiosis outbreaks. Coccidiosis in Calves Coccidia are single celled protozoa of the Eimeria species. Small numbers of these organisms are normally present in the intestine of all animals and their eggs or oocysts are continually shed into the environment via the faeces. Coccidia numbers in the intestine are normally controlled by natural immunity which develops with exposure to the organism in low numbers. However, when the calf's immune system is compromised due to stress from management changes, nutritional upset, vaccination, adverse weather, bacterial or viral scours or any other cause, there may be a rapid increase in coccidia numbers which damage the intestinal lining of the calf. This often results in bloody scours and the calf losses water, electrolytes, blood and tissue. This leads to dehydration, anemia and death. Secondary infection frequently develops due to low immunity. |

Sub-clinical or low level coccidiosis is less obvious but can
interfere with feed consumption and utilisation, resulting in poorer
feed conversion, weight gain and general health. Mild infection may
show as a watery scour for a few days followed by a slow recovery
but subsequent performance may be poor. It is during the first 6
months that calves are most susceptible to coccidiosis. Stresses are
more frequent and severe and a calf may require up to five exposures
to full coccidia life cycles to develop adequate immunity.
Bovatec is a coccidiocide and acts by disrupting the cation balance the the bacterial cells causing an increase in water pressure within the cell due to osmosis resulting in the bacterial cells bursting before they can reach the intestinal wall. Calf Vigor Vitamins Vitamin A: promotes mucous membrane repair and integrity, and aids vision, growth and tissue repair. Vitamin D: stimulates the absorption and metabolism of calcium and phosphorus for the formation of bone and teeth. Vitamin C: important for the immune system and in bone, teeth and connective tissue formation. Vitamin E: this vitamin is a cellular anti-oxidant which protects cells from free radical damage. Free radicals may come from normal metabolic breakdown of food or from food contaminants or oxidative breakdown such as those produced from rancid fats. It is also crucial in organ development and the immune system. B Group Vitamins: these are dietary essentials for pre-ruminant calves. Once the rumen is fully developed after 6-10 weeks the rumen microbes normally produce sufficient B vitamins to meet requirements. B vitamins are active in enzyme systems involving energy and protein. Directions for Use Dose Rate: 25 grams / calf / day. Method: mix into whole milk or reconstituted milk replacer once per day from 2 days of age and continue until intakes of meal feed, containing an anti-coccidial, are sufficient to supply an anti-coccidial dose sufficient to protect calves from infection. Typically this will be between 3 and 5 weeks of age depending on the rearing system employed. Do not feed to calves under 2 days of age, do not add to milk replacers which already contain an anti-coccidial, do not feed to horses or dogs as anti-coccidial toxicity may be fatal in these species.
