-
Gammulin is a functional protein supplement for calves that is used on days 2–15 following birth, and for extra nutritional support in the face of other challenging conditions such as extreme weather. Gammulin should be mixed with whole milk or calf milk replacer.
-
Gammulin will have its greatest impact when fed at the rate of 1 oz (28 g) per calf, per day, divided into two milk feedings. During periods of added or prolonged challenge, Gammulin should be increased to 2 oz (57 g) per calf, per day, divided into two milk feedings.
-
There is no harm in feeding Gammulin to a calf before 24 hours of age as long as it is fed at its normal feeding rate (up to 2 oz per calf, per day). There are certain minerals and vitamins in Gammulin that may be overfed if Gammulin is given at higher than normal levels in the first 24 hours of life. It is recommended to begin feeding Gammulin to calves on Day 2 or later.
-
Yes. When stress continues beyond 15 days of age, continue feeding Gammulin for at least 1 week beyond the end of the challenge.
-
In addition to functional proteins, Gammulin also contains a special mixture of minerals, vitamins and oligosaccharides that can help with the nutritional needs of the calf in its first few weeks of life.
-
Gammulin should be mixed with either pasteurized whole milk or milk replacer. The real benefit from feeding the functional proteins in Gammulin will come when they are fed at the same time as the milk feeding.
-
Gammulin is specially formulated to ensure easy mixing with milk or milk replacer. For best results, mix Gammulin into warm (105°F) milk or milk replacer and agitate by whisk or mechanical mixer until no lumps are seen. Do not mix Gammulin into hot (>140°F) milk or milk replacer, as high temperatures may damage the functional proteins in Gammulin.
-
Gammulin should be mixed and fed to calves twice a day. The benefit of using functional proteins is maximized by feeding them each time the calf is offered milk or milk replacer.
-
Gammulin has a 36-month shelf life when the product is stored unopened at room temperature in a dry place. Once exposed to air, the powder should be used within a few days. Once Gammulin is mixed with milk or milk replacer, it should be used immediately and never stored.
-
No other calf nutritional supplement on the market has undergone the same extensive independent research as Gammulin, nor does any product have the level of repeat use by experienced calf raisers as Gammulin. Extensive research by APC, independent universities and many large calf operations has been published in peer-reviewed scientific journals. Gammulin is widely accepted as an effective and trustworthy product.
-
Gammulin is a proven performer that has been on the market for more than a decade, and is a must-have product on many “high challenge” calf operations across the U.S., such as veal operations where calf raisers have low tolerance for products that do not deliver results. In addition, Gammulin has been evaluated through several independent university research trials and results have repeatedly shown Gammulin to be an effective additive that should be routinely used in calves on Days 2-15 of life.
