Show Higher Yields Outweigh Cattle Spraying Costs An increase of $3.75 per head more than covers the cost of spraying beef cattle with DDT, it was revealed re-vealed in a test of the value of fly control conducted at the University of Illinois college of agriculture. Protected cattle gained about 15 pounds more per head during the pasture season than a group that had not been sprayed. At 25 cents a pound, an increase of 15 pounds a head amounts to $3.75 a head, a return that far outweighs the cost of spraying. Beef cattle should be sprayed often enough to control flies, whether it requires two or three sprayings during the season or once a month. |
