Show DISEASE IS FOUND IN POULTRY YARDS Rotation or Cropping Will Prove Helpful. By Dr. Robert Graham. Chief In Animal Pathology, College of Agriculture, University Uni-versity of Illinois. WNU Service. Disease organisms, worms and coc-cidiosis coc-cidiosis germs which are found in contaminated con-taminated soil and constitute the greatest menace to poultry production produc-tion can be controlled only by proper management, Including the rotation oi-cropping oi-cropping of poultry yards. No medicine will correct the ailments ail-ments caused by "chicken sick" ground, notwithstanding the claims of remedy venders to the contrary. All intestinal and parasitic diseases of chickens, as well as contagious germs such as coccidiosls, are spread by the droppings of infected fowls. Thus the soil of many poultry yards becomes an incubator or seed bed for the propagation and spread of these diseases. To overcome the development of disease dis-ease germs, poultrymen who hope to reap a profit from their efforts must rear their chicks on clean ground and plow, cultivate and crop the old chicken yards. Rotation of the poultry range so that It is used but once in every four years is a profitable practice on farms where this can be done. In cases where extensive rotation of the poultry range is not possible, keeping keep-ing the chickens out of the yard until the ground can be plowed and a new seeding gets well started is helpfuL For summer planting, a combination of oats and rape makes a satisfactory mixture. An ordinary farm disc Is probably the most satisfactory tool to use in working the poultry yard, although al-though a plow may do just as well. The latter implement, however, tends to bring to the surface the contamination contamina-tion which has been plowed under the previous year. |
