PROTECT YOUR CALVES WHEN THEY NEED IT MOST
PROTECT is a colostrum supplement, designed to be fed alongside maternal colostrum or as a supportive second feeding. Each serving delivers 50 g of globulin protein plus 20% added fat and carbohydrates, providing calves with the critical antibodies, nutrients, and energy they need to thrive in their first hours of life. Because every calf deserves a strong start, PROTECT helps fill gaps when maternal colostrum is limited or quality is uncertain, building immunity and supporting early growth when it matters most.

THE ADVANTAGE OF SERUM BASED FORMULAS
At LIFELINE®, we build our formulas on a powerful serum-based foundation because calves only get one chance at a strong start. Serum-based formulas are naturally rich in functional globulin proteins and growth factors—essential components that help newborns thrive during their most vulnerable stage.
These functional proteins work where it matters most:
Strengthening immunity to better fight early-life challenges
Promoting gut health and nutrient absorption for optimal growth
Delivering energy calves can use right away
With over 600 peer-reviewed studies confirming their effectiveness, serum- and plasma-based globulin proteins are a proven way to improve calf health, growth, and survival. That’s why we choose this superior foundation for every LIFELINE product—so you can be confident your calves have the best start possible.
FAQ
-
Protect is a colostrum supplement produced from high-quality, nutrient-rich plasma. Protect is the only colostrum supplement formulated with 20% added fat plus carbohydrates for extra energy. Protect provides 50 grams of globulin protein in a single feeding and is designed to reduce variation in maternal colostrum.
-
A colostrum supplement is a powdered product that helps nutritionally support a newborn calf and offers a minimum of 50 grams of globulin protein, and ideally fat and carbohydrates as well. A colostrum supplement is mixed with water and fed to a calf in addition to maternal colostrum. Colostrum supplements are designed to bridge a calf’s nutritional needs in a cost-effective manner.
-
Most colostrum supplements are made from dried bovine colostrum powder. Protect is made from nutrient-rich plasma, the most highly researched source of globulin protein in a colostrum supplement. A single, 2-quart feeding of Protect provides 50 grams of globulin protein, plus energy calves need at birth.
-
In addition to globulin protein, Protect contains additional functional proteins from plasma, plus a researched blend of carbohydrates and fat that help support the nutritional needs of newborn calves.
-
Protect can be fed before colostrum to beef calves that may not have nursed, or after colostrum to beef and dairy calves that didn’t receive enough maternal colostrum. Ideally, Protect should be fed within 24 hours of birth.
-
There is no harm in feeding Protect after 24 hours of age, but the greatest benefits of Protect are seen when it is fed in the first few hours following birth.
-
Protect is designed to supplement maternal colostrum. LIFELINE Nourish and LIFELINE Rescue are colostrum replacers that can be fed in place of maternal colostrum.
-
Protect should be mixed into warm water only and fed to the calf in addition to colostrum.
-
Protect mixes extremely well with water in under a minute. It should be added to warm (105°F) water with continuous agitation by wire whisk or mechanical mixer. Feed Protect to calves once it has reached a smooth consistency and all lumps are gone. Do not mix Protect in water hotter than 140°F, as high temperatures may damage the functional proteins.
-
Protect has a 36-month shelf life when stored unopened in a cool, dry place at a temperature of 50°–86°F. Once the powder is exposed to air, it has a very short shelf life and should be used within a few days. Once Protect is mixed with water, it should be immediately used and never stored.
