Cut directly through the center of the enlargement, clean to the bottom, splitting it wide open. Clean it out with peroxide of hydrogen, after which saturate absorbent cotton with tincture iodine, pack in tight and sew the skin to hold it in place. Remove the dressing in 48 hours and wash with sheep dip (tablespoon to 1 quart of warm water) twice daily. This may be tubercular, or the result of foxtail, etc. Cow Chewing Bones. One of my cows is continually chewing bones. What can I do to prevent it? Give the cow good clean hay; some root crop, cocoanut meal, bran or soy-bean meal. If the cow does not stop mix in the drinking water twice daily a little dilute hydrochloric acid. Also, have boxes arranged near feeding stalls which contain wood ashes, slaked lime and salt. Swelling on the Dewlap. I have a cow that has a large lump at the point of the breastbone, the dewlap. This lump is as large as a cocoanut, and was caused, I think, by friction against a low manger in eating. Get equal parts of tincture of iodine and soap liniment and rub onto the swelling twice daily for a week. Barren Heifers. I have three heifers, 3 years old, which have run with the bull right along and have failed with calf; have had three different bulls to them; what can be done? There is a possibility of contagious abortion causing these heifers to fail to breed. If this has occurred in the herd, the heifers are very apt to be affected. If apparently healthy, reduce me feed and make the heifers take considerable exercise to reduce flesh. Give each a dram of powdered nux vomIca and one-half dram of dried sulphate of iron once daily in a little feed. Breed to a healthy bull when the heifers come in heat. A Sterile Cow. I have a very fine Jersey cow. I have had her to the bull every month, and can't get her with calf. In an isolated case of this kind there is probably some disease of the generative organs or some condition whereby the impregnation cannot occur even when the animal is bred. The ovaries may be cystic; there may be chronic inflammation of the womb and possibly the mouth of the womb was injured at last calf birth and the scar prevents its admitting the fertilizing cells. If possible, a veterinarian should make a careful examination of this cow in order to determine what the trouble is. However, this treatment may be tried: About the time of coming in heat, give the cow a large dose of glaubers salts (one pound) and the nux vomica and iron treatment advised for "Barren Heifers" in another paragraph. Before breeding the cow, apply a little extract of belladonna and glycerine to the mouth of the womb and breed a few hours after. Supernumerary Teat.
