Since you've opened this post even after reading the title, I suppose there's no need to warn you these pictures are a bit graphic. :lol2: :P

Normal internal organs

3-4 week old calf

Heart
Image

Lungs (lobed; 4 on the right side, 3 on the left side) -- note that lungs should FLOAT in water
Image

Stomach (cow has one stomach composed of 4 chambers, NOT four stomachs)
Image

Liver (lobed)
Image

Gallbladder (yellow fluid is called bile, released into intestine and contains bile salts which assist in the breakdown of fats)
Image

Kidney (bovine kidneys are lobed, have 15-25 lobes according to the anatomy book)
Image

Spleen
Image

Uterus (note that this is a CALF -- ovaries in a cow are only slightly larger but the rest of the reproductive tract is some 4-5 times this size)
Image

I'll get more normal pictures over time and update this thread as I have the opportunity to do so.

Abnormal parts

Joint infection in a calf (just happens to be the one above :P)
Image

Image

Peritonitis in a fresh cow... a reminder to be careful not to go through the uterine wall when infusing cows with uterine infections. This cow's entire abdominal cavity was filled with uterine fluids and placental membranes; was a foul smelling mess. The omentum is part of the abdominal membrane that encloses the intestines (I'm told it also provides support).
Image

Another deadly result of infusing a fresh cow -- low doses of oxytetracycline can safely be used to infuse a cow with a uterine infection, but more is NOT always better! This cow was infused with over 250mLs of oxytetracycline 200mg/mL. The result is a nasty uterine abcess that repeatedly broke open and drained into the abdominal cavity, causing a chronically sick cow and excessive tissue around the reproductive tract. Two months after initial infusion the abcess was the size of a football (according to my vet), when the cow was put down it was the size of a baseball. Normal color for a mature cow's repro tract is a pinkish-red, NOT white.

Thanks, I learned something new from your post today. Did not know that bovine kidneys are lobed.

You're welcome, folks. Farmgirl -- I didn't know that either until I did a bit of research prior to working on the calf. Once I read they were lobed I had to make a special point of finding the kidneys since it sounded fascinating. Definitely looks different than the fetal pig I dissected in class last semester. :lol2:
