Yes, pre-weaned animals and dams are on ‘clean’ pastures

Dams and pre-weaned may be on pasture only with other young animals or only with animals post worming treatment

Is manure spread on pastures prior to grazing during the same growing season?

No, manure is not spread on pastures or fields to be grazed

Manure is only spread in the fall prior to the next growing season, or manure is spread and then hay is made

Manure is spread after hay is harvested the same growing season, prior to this field being used for grazing

Manure is spread on pastures and grazed the same season

Are animals of various ages and stages of production on the same pasture?

No, each age group or production group is grazed separately

Animals groups may use the same pasture in a growing season, but there are several weeks between grazing times

Younger animals always forward graze ahead of older animals

Different ages and production stages are on the pasture at the same time

Does the producer have a systematic means of determining which animals need anthelminthic treatment?

Yes, producer follows FAMACHA or other tested system

Does the producer have a strategic parasite control program?

Yes, producer matches use of anthelminthics with environmental control methods and animal reservoirs

Producer uses pooled egg counts to monitor effectiveness and timing

Producer uses anthelminthics several times after grazing season begins

Producer uses various anthelminthics when clinical signs appear or when weight loss is noticed

Does the producer work with his/her veterinarian to determine which therapy plan will be most effective, has a strategy, and considers resistance factors.

Yes, effective, tested products at appropriate rates are used only within a control program that includes animal and environment

Products are selected and used just based on published label claims

Products are selected and used based on advertising or word of mouth claims

Products are used without a real plan or sense of purpose
