Animal waste--the smell of success or the stench of srouble?

摘要

Yrears ago on out way to town. in the Model T or Model A, we would smell the odor of freshly spread barnyard manure, which my dad called "the mortgage-lifting aroma," To all of us it meant spring, crop fertilization, and dean barnyards, Gur neighbor had a habit of putting the heaviest application of manure near the road so that their corn or beans looked the best when compared with other neighbors' crops. We always had a debate as to which had the worst odor, swine manure or cattle manure. Swine manure always won. Food animal practitioners were reminded, especially if they didn't scrub their boots well, that swine manure won again. This was particularly trae in the winter when it thawed off your boots as the heater finally yielded its full force. Working in barns and pens that were not cleaned created extra stress and poor working conditions, but was usually accepted by veterinarians.
