Fall Management: Deworming Strategies

摘要

The term, strategic deworming is often used to describe deworming timing for your climate and parasite challenge. Research from late 1990's calculated the economic impact of fall and spring deworming from 16 to 49 pounds (average 31 pounds). The extraweight gain is great, but we also need to look at product and labor cost. Conservatively we can assume de-wormer cost is $2.50 for the 1,300 pounds cow (fall and spring application) and $.50 for the calf (late June only). That puts total dewormer cost at $5.50. Chute charge at $l/head adds another $3. This brings the seasonal deworming program cost to $8.50/head.
