Methods of applying chemicals to livestock
- Dipping:
- This is very effective if large numbers of livestock need to be treated.
- All body parts have adequate contact with the chemical solution since animals are completely wetted.
- Dipping should be done in the early morning so that animals are not immediately exposed to the hot sun.
- Dipping is not recommended if heavy rain is expected soon after, as the chemical may be washed off quickly.
- Hand Spraying:
- Hand spraying using knapsack sprayers is the most commonly used method.
- It is effective especially if a small number of animals are to be treated.
- During spraying, the animal should be tied securely and the entire animal should be sprayed by following a strict sequence starting at the head and finishing at the tail to cover all areas of the body thoroughly.
- Pour on Acaricides:
- A small volume of special Acaricides is poured along the backline of an animal.
- It disperses over the body surface to kill the infesting ectoparasites.
- Injection:
- This is a relatively new form of a systemic pesticide such as Ivomac.
- This is simply injected into the animal. There is a broad spectrum of action against a host of parasites.
