Dairy Herd Spraying Could Add At Least $75 This Summer
Illinois agricultural specialist H B Petty says spraying dairy cattle with methoxychlor to control stable and horn flies could yield at least $75 extra profit this summer. Field tests show 15 percent more milk possible through September, with conservative estimates of 2,550 pounds extra milk for a 15 cow herd, worth about $15 more in milk checks. Spraying costs 20 to 25 cents per head. Petty recommends spraying barn interiors two to three times, using one pound of 50 percent methoxychlor in two to four gallons water per 1,000 sq ft, and spraying cattle every two to four weeks with one quart per cow.
