Spring Calving - Care of Newborns
Spring calving is just around the corner. The following article addresses getting the newborn calf breathing well. If your cow or heifer has had a lengthy calving ordeal, the newborn may need help even if it appears to be breathing.

"Delayed passage through the birth canal in the face of a faltering placenta compromises oxygenation of the calf. Although the calf is able to breathe as soon as its nose passes the lips of the vulva, expansion of the chest is restricted by the narrow birth canal. This situation is seriously aggravated when continuous forced traction is applied. As soon as the calf's head has passed the lips of the vulva, traction should be interrupted, the nostrils cleared of mucus and cold water applied to the head.
Again, when the calf is completely delivered, primary attention is directed toward establishing respiration. Mucus and fetal fluids should be expressed from the nose and mouth by external pressure of the thumbs along the bridge of the nose and the flat fingers underneath the jaws, sliding from the level of the eyes toward the muzzle. The common practice of suspending the calf by it hindlegs to "clear the lungs", must be questioned. Most of the fluids that drain from the mouth of these calves probably come from the stomach, and the weight of the intestines on the diaphragm makes expansion of the lungs difficult. The most effective way to clear the airway is by suction.
Respiration is stimulated by many factors, but only ventilation of the lungs, allow us to render help immediately. Brisk rubbing of the skin and tickling inside the nostril with a piece of straw also has a favorable effect. The phrenic nerve can be stimulated with a sharp tap on the chest slightly above and behind where the heartbeat can be felt."
