BUTOX® SWISH has no milk withdrawal period meaning no break in production is needed. For the best result, it’s important to start treating the herd as soon as the risk period occurs. Continue with treatment throughout the season to ensure flies don’t become a problem later down the line. Remember, two flies can become one million in four months if left untreated.
As temperatures rise over 10 degrees, fly eggs will start hatching. Flies cause distress, known as fly ‘worry’, severely reducing milk yield because it causes restlessness and reduces the time cows are eating. It’s estimated this reduction can be as much as 14,700 of milk per 140 cow herd over 10 weeks1,2, which is significant.
These pests transmit dangerous diseases, such as summer mastitis later in the year, so control is vital. Act now to prevent adults from laying further generations of eggs which could contribute to population explosions. If you wait to see flies, it is already too late.
By acting now with BUTOX® SWISH Herd Pack, you’ll be more likely to successfully reduce fly populations and the negative effect this can have on productivity and milk yield.
