Parasite Control

Early summer deworming of nursing calves

Five deworming trials were conducted at the Eastern Research Station located near Haskell, Oklahoma during the 1990’s. Crossbred cows and their Charolais sired calves were sorted by sex of calf, calf age and cow age, then randomly allotted to one of four treatments.

Deworming cattle is a springtime chore

If you plan on deworming cattle, spring is the right time. Parasite burdens in pastures peak during the spring, drop over the summer, and rise again in the fall.

Costs and benefits associated with preconditioning calves

Preconditioning is the process of preparing calves to enter the stocker phase of the beef industry or to be directly placed in the feedlot.

Do You Know The Enemy? Don't Let The Brown Stomach Worm's One-Two Punch Knockout Your Profits

As we approach spring working of cows and calves and the growth of new pasture, it is important to understand the life cycle of cattle's most common problem parasite, the brown stomach worm (Ostertagia ostertagi).

BI: Test Herd, Then Treat To Avoid Parasite Resistance

As instances of internal parasite resistance to deworming treatments are becoming more numerous among the country's cattle herds, it becomes apparent that herd managers must pay closer attention to the use of these valuable herd-health tools.

Cattle Parasite Control & Chemical Resistance

Are there lessons about worm control that we can learn from sheep producers?

The importance of controlling parasites

Research continues to find new ways to demonstrate it.
