Controlling Insects For Healthier Cattle CATTLE protected against horse and horn flies are healthier and have greater muscular develop ment than unprotected cattle, ac cording to a 2-year sudy conducted by the Delta Branch Experiment Station at Stoneville, Miss. ARS entomologist Richard H. Roberts said that test cattle, sprayed on a weekly basis with an insecticide mixture, were plagued by fewer flies and gained more weight than an untreated control group. The cattle were sprayed with a water-based spray containing 0.5 percent methoxychlor, 0.5 percent carbaryl, 0.1 percent pyrethiins and 1.0 percent piperonyl butoxide. The day before and after each treatment, the number of horse flies and horn flies were counted on all animals between 1 p.m. and 3 p.m. Previous data showed that a greater percentage of flies fed on the cattle at that time of day. Hemoglobin and hematocrit values (ratio of red blood cells to the volume of whole blood) were obtained every 2 weeks to deter mine whether blood reproduction capabilities had any reaction to in sect feeding. The animals were weighed every 4 weeks during the study.

Results showed that control of horn flies was excc’lent. Control of horse flies ranged from good to e\ce”ent the day after the treat ment, to fair the day before the next treatment a week later. During one year’s tests, on the day before the next treatment, re sults showed a 100-percent reduc tion in the number of horn flies on the treated cattle over the untreated gioup. The following year, there was a 98-percent reduction over the un treated group. The treated group showed a 53- pcrcent reduction of horse flies occr the untreated group the first year. and a 75-percent reduction the next. The 22-percentage-point range was attributed to field vari ability and weather conditions. During the first )car the treated steers gained an average of 0.20 pounds per da) per animal over the untreated steers; the next year, the gain was 0.23 pounds per day per animal under pasture condi tions. The treated group, under feedlot DRYER DRIES MORE EFFICIENTLY WILL DRY 50 PER CENT MOISTURE DOWN TO 12-15 PER CENT MOISTURE ON DISPLAY AT FARM SERVICE conditions, had an average daily weight gain slightly higher, while requiring less feed per pound gained than the control group. During the first year the treated group required .45 pounds less feed per pound of gain than the control group, while during the fol lowing year, the treated group re quired .59 pounds less feed per pound gained.
