Horn, Face and Stable Fly Control with Feed Additive Insecticides, 1972-75

Rabon and Famphur were used either as mineral or feed additives. In some of the trials the herds were isolated and in others they were not. The stable fly control trial was at a dairy where cattle were restricted to lots. In several of the trials the control herds were treated by spraying or, at the dairy, mist applications of naled were used. Horn flies were counted on 1 side of an animal with the aid of binoculars. Face flies were counted on the face of animals also with the aid of binoculars. Stable flies were counted on the outside of 1 leg and the inside of the other and the count termed flies/leg. Counts were taken on 10% of the animals with a minimum of 15 animals/count. All herds with the exception of the dairy cattle were yearlings.
