Udder Disaster!
www.cartoonstock.com
Old McDonald had a farm and on that farm there were some cows. You are Mr. McDonald’s
trusty veterinarian and you receive a call from him early this morning. Three of his cows are very
sick! You rush to the farm and find that each cow is having different symptoms. One cow looks
more critical than the others, but each one needs your help as soon as possible!
Instructions:
First, use your web resources to diagnose each cow with their respective nutritional disease
and give evidence to support your conclusions. Second, decide in which order you will treat the
cows and explain why. Third, come up with a plan of action. Describe, in detail, how you will
treat the individual cows, explain their recovery processes and determine the outlook for each.
When describing their outlooks, please make a recommendation for each cow on if treatment is
a practical option. Last, develop a prevention plan for the herd that Mr. McDonald can use to
help prevent these nutritional diseases in his cattle in the future.
After you have completed your individual assignment, gather into groups of three to discuss
your findings. If your answers differ, compare your evidences and come to a consensus on a
diagnosis. Prepare to present and prove your findings to the rest of the class at the end of the
period.

Case Studies:
Old Bessy:
The first cow you come upon is lying on her side in her stall. She struggles to a standing
position, staggers and falls back down again. Old McDonald informs you that she just recently
calved. You take her temperature and it is below normal. Although she is eating, she seems
very weak. As you continue to watch her, you notice that she continues to turn her head and
hold it over her right shoulder.
Miss Daisy:
The second cow you examine is a yearling heifer. The first thing you notice about her is her
body condition. She is extremely emaciated, unusual for a dairy cow that isn’t lactating and has
never calved. You look closer and notice her oddly shaped joins. Her legs seem to be bowing at
the knees and she is walking stiffly. You ask about her eating habits and Old McDonald informs
you that she has been off her feed for several weeks.
Little Susie-Lou:
The last cow you are asked to see is an eight-week-old dairy heifer-calf. Although young, the
calf is small for it’s age. You notice some emaciation and ask about it’s appetite—Old McDonald
informs you that the calf rarely nurses. You run your hand down her back and notice that her
coat is coarse and that there is some swelling behind her shoulders. You decide to check her
gums and they are pale and yellow.

Conclusion:
These skills can be applied in many different facets of life. Students will be able to use their
proficiency in livestock nutritional diseases when caring for their Supervised Agricultural
Experience projects which could include meat, production or breeding livestock. As well, these
skills can be put into use in future careers as animal dieticians, animal nutritionists, veterinarians,
veterinary technicians, or livestock producers.
