How to deal with a cow with down syndrome

Downer cows are often hypocalcemic. If an apparently hypocalcemic cow does not respond to calcium therapy, phosphorus, magnesium, and potassium should be given as additional treatments pending the results of laboratory tests. Monitoring the blood mineral status is an important part of downer cow management.

In most cases, recovery depends on the quality of recumbency management and nursing care. Lateral recumbency must be corrected immediately to avoid regurgitation and inspiration of stomach contents. The animal should be rolled into sternal recumbency. However, if this posture is to be maintained, the limb on which the animal has been lying should be drawn from under the body. In other words, if the animal was presented in lateral recumbency on its left side, it should be rolled into sternal recumbency on its right side. Support (eg, straw bale) placed under the shoulder may be required for some animals to maintain sternal recumbency. 

Attempting to stabilize a recumbent cow on a concrete surface is highly undesirable but sometimes unavoidable. Bedding the area around and under the cow with wet, sticky manure to a depth ?6 in. is a common practice. At least 10 in. of dry straw should be distributed over the wet mass. If the cow struggles and scrapes the wet manure, exposing concrete, more manure must be added. The so-called manure pack provides good footing but also may soil the skin with urine and manure. Dermatitis can result, and comfort of the cow is reduced. More seriously, the risk of mastitis resulting from the contaminated environment is very high. A bed of sand ?10 in. deep is more effective. This usually drains well, and good hygiene can be maintained if the manure is removed several times each day.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
