Practices to gain a 50-pound advantage

Spring turnout is a prime opportunity to set a healthy foundation for the long-term success of your calves. Two highly impactful practices to consider before turning calves out on pasture are implanting and deworming.

John Hutcheson, Ph.D., director of beef cattle technical services for Merck Animal Health shares how removing parasite pressure while increasing average daily gain with implants can result in as much as a 50-pound advantage per calf.

Focus on spring parasite management

Springtime is a critical period to make sure you’re reducing internal parasite challenges. Grant Crawford, Ph.D., associate director, cattle technical services for Merck Animal Health, explains the impact internal parasites can have on performance efficiencies.

Protect calves early with intranasal vaccination  

From birth to about 3 months of age, young calves are especially susceptible to pneumonia caused by bovine respiratory disease (BRD), making early protection critical. Tim Parks, D.V.M., technical services veterinarian for Merck Animal Health, shares how intranasal vaccination can help stimulate the immune system without maternal antibody interference — giving calves the strong start they need to stay healthy and keep gaining.

Increase calf weaning weights

Using the right implant at the right time can result in continued performance and continued gain, starting with suckling calves. Hear from Brandon Nuttelman, Ph.D., cattle technical services manager for Merck Animal Health, how a strategically timed calf implant can result in as much as 23 pounds of pure added gains at weaning and beyond.

Keep pastures and cattle clean with a summer dewormer

Keeping parasites off grass and out of animals should be the cornerstone of cattle summer health protocols. Brandon Nuttelman, Ph.D., cattle technical services manager for Merck Animal Health, explains how feed and mineral-based dewormers can save producers a trip through the chute while reducing parasite pressure.

Learn more about SAFE-GUARD® (fenbendazole) and its many formulations so you can deworm the way that’s best for you.

Get the most of your grazing with cattle implants

One of the best ways to increase weight gain during the preconditioning phase is with a cattle implant. Lee-Anne Walter, Ph.D., cattle technical services manager for Merck Animal Health, shares why an implant can help build on calf performance, resulting in better average daily gains and the potential of 10-12 pounds per head at the end of preconditioning.

Learn more about REVALOR®-G (trenbolone acetate and estradiol), an implant worth its weight in real-world grazing periods.

Precondition for healthier, higher-value calves

Producers need to consider how to build on good practices and protocols used early in the spring to keep getting the most out of their animals. Tim Parks, D.V.M., technical services veterinarian for Merck Animal Health, talks about key components of preconditioning programs — like longer weaning periods and robust vaccination protocols – that can give producers a marketing edge and help make the most of their investment.
