Calf Diarrhea: Two Causes, Two Strategies

This month’s “Ask the Vet‘ mailbag we look into one of the most devastating diseases affecting calf raisers. Calf scours are an economically devastating primarily because scours cause calves to rapidly dehydrate. Providing proper hydration can help shorten the severity and duration of calf scours. Electrolyte therapy should be paired with a prevention plan to address the cause of the scours. Choosing the right electrolyte for the job at hand can be confusing. Crystal Creek® is here to help. Listen as Dr. Ryan Leiterman from Crystal Creek explains:

Mixing Milk Replacer A Daily Task

Mixing milk replacer to feed pre-weaned calves is a daily task on many farms. And it’s a simple task, right? All it takes is adding the correct amount of powdered milk replacer to the correct amount of water, how hard can that be? That’s our question to Dr. Ryan Leiterman on this month’s “Ask the Vet” segment:


Testing For Ketosis

Research from the University of Wisconsin-Madison predicts that 40-45% of dairy cows develop ketosis within the first 30 days of milk. Dr. Ryan Leiterman begins a series on why testing for ketosis is crucial for a dairy producers bottom-line.

Knowing Your Calf Vaccines

Young calves need vaccinations to stay healthy and productive; but what type of vaccine should you use? In this June segment of Ask the Vet, Dr. Ryan Leiterman of Crystal Creek tells us the different types of vaccines available and why it is important to always know what type of vaccine you are including in your protocol.


Spring Has Sprung

Spring is an excellent time to plan your upcoming construction projects. Some of the more common calf barn designs incorporate naturally ventilated, curtain sidewall barns. Dr. Ryan Leiterman reminds us how to properly use curtains, eves and ridge vents as we ease out of the colder months.

Winter Housing: Focus On Air Volume Not Speed

Cold temperatures are here and winter is quickly approaching. As the temperatures drop, calf barns are closed up and the ventilation rates are turned down. As an industry we do this reflexively, but is it what’s best for the calves? If it’s not ‘drafty,’ can a calf have too much fresh air? Dr. Ryan Leiterman of Crystal Creek tells us more on this month’s A Breath of Fresh Air on Dairy Radio Now:
