DISEASES OF CATTLE. 73 



GENITAL DISEASE. 



As the genital organ diseases are usually due to retention of the afterbirth, this 

 subject is fully described and the treatment fully given under subject of Afterbirth 

 Retained in foregoing pages. 



See Prcscril'tioii No. 35, /"o^ic 175. 



GESTATION PERIOD. 



As it is pretty well known by most people that the gestation period of a cow is 

 nine months, or 280 to 285 days, it will be needless for much to be said on this sub- 

 ject, as gestation table may be seen on page 20. (A calf born on the 210th day may 

 live; also 336th.) A cow failing to carry her calf to the period of 280 days may be 

 considered an abortion, and this subject is thoroughly described under heading 

 Abortion. 



GONORRHOEA IN BULLS. 



Gonorrhoea is an infectious catarrhal discharge of the genital organs. It is 

 brought on by coming in contact with living germs, such as serving a cow afflicted 

 with infectious abortion, or one that has retained the afterbirth, and comes in heat 

 while she is still discharging. 



Treatment. 



All herd bulls should have the sheath washed out after each service with a solu- 

 tion of Antisepto to prevent becoming affected and contracting gonorrhcea. It is 

 due to this disease that infectious abortion is spread. 



See Prescriftion No. 36, page 175. 



GRASS STAGGERS. 



Grass Staggers is a disease brought on by overloading the stomach with grass. 

 As soon as the stomach becomes overloaded, indigestion sets in, which interferes with 

 the brain, causing the animal to walk with an unnatural and unsteady gait, usually 

 walking in a circle, and oftentimes staggering and falling. If she is filled with gas, 

 she should be tapped with a cattle trocar to prevent death from smothering. If 

 noticed in time, or before she goes down, small doses of Laxatonic should be given 

 according to directions, until she recovers. A gag may be placed in her mouth. 



See Prescription No. 37, page 175. 



GRUBS OR WARBLES IN SKIN OF CATTLE. 



Grubs or Warbles in the skin of cattle are caused by a fly which deposits its egg 

 during the summer months in or on the skin of the animal, and the egg is retained 

 in the winter months in a little round sack beneath the skin, having a small opening 

 through which the larva escapes in the early part of the following summer and 

 develops into a fly. 



Treatment. 



To overcome and prevent the development or hatching of this fly, the grub which 

 is found beneath the skin of the animal along the back, and is known by a swelling 

 about the size of a boil, should be opened by squeezing; then inject a little Healing 

 Oil a few times by the use of a small oil-can. The time to do this is during the 

 early part of spring.
