Cochran, former Iowa State poultry husbandman, husband-man, has said. Coryxa is caused by a bacteria that can easily be seen by an experienced veterinarian or In a bacteriological laboratory dlag-nosis. dlag-nosis. Heakhy fowls may readily eon-tract eon-tract the disease from diseased chickens, recent experiments at the University of California have proved. The spread Is carried through contact, but cages, water troughs and feed equipment and other apparatus do not bold germs for more than 24 hours. "Discovery of these facts would ordinarily make the poultryman believe be-lieve control and prevention of the disease are relatively easy," Mr. Cochran said. "But there is a Joker. Further experiments show that birds may be infected with the disease dis-ease as long as 44 days without showing any apparent signs. Yet they can carry enough of the organisms organ-isms that the germs are spread to the healthy birds without warning." The California tests showed that turkeys were Just as susceptible to coryaa as are chickens, and show the same reactions. In most chicken chick-en flocks the disease can be stopped before mortality Is particularly t heavy, but the great damage is dons in the decrease of egg production. Sprouted oats or other young greens should be easy to raise now with weather conditions moderating, and such feed is valuable to tha growing chick and mature flock alike both for turkeys and chickens. chick-ens. If, on the other hand, there are no facilities for raising such greens, the mash needs an auxiliary. The vitamin O content of the daily ration should be increased to the highest possible point In order that the growing ability of tha chick may be encouraged. Claims of some operators that feeding greens to chicks causes diarrhea among them are discounted dis-counted by R, R. Hennas, midwest poultry authority. The trouble Is being caused by some Improper condition, con-dition, probably extreme temperatures tempera-tures under the brooder hover. Sudden change of temperature under the hover Is Just as serious as some diseases, Mr. Hannaa said. Diarrhea is seldom fatal, but re- ; duces the resistance of the chick, opening the way for many diseases that are prevalent during the grow-ing grow-ing period. caused considerable trouble already this season at brooding farms.
