Ecomectin 6 mg/g Premix for Medicated Feeding Stuff for Pigs

To ensure administration of a correct dose, body weight should be determined as
accurately as possible; accuracy of the dosing device should be checked.
To ensure thorough dispersion of the product it should first be mixed with a suitable
quantity of feed ingredients before incorporation in the final mix.
The recommended dose level is 0.1 mg ivermectin/kg bodyweight fed daily for seven
consecutive days. The appropriate inclusion rate of the product, in grams per tonne
of finished feed, can be calculated as follows:
100 x average bodyweight (kg)
Premix inclusion rate = -------------------------------------------
(g/tonne feed) 6 x average daily feed intake (kg)
In order to avoid under or overdosing, pigs to be treated should be grouped by weight
and the dose to be administered should be calculated based on the heaviest animal
in the group.
Growing Pigs
The recommended dose level of 0.1 mg/kg bodyweight daily for seven days is
obtained under most circumstances, for pigs up to 40 kg bodyweight, by including
333 g product in each metric tonne of final feed. The product should be thoroughly
mixed in the finished feed and fed continuously as the only ration for seven
consecutive days. In pigs weighing 40 kg liveweight and over, average daily feed
consumption may fall below a feed intake of 5% of bodyweight where restricted
feeding programmes are in use or where pigs are fed a ration high in protein.
For pigs weighing 40 kg and over, include 400 g product in each metric tonne of final
feed.
Adult Pigs
The recommended dose level for adult pigs weighing over 100 kg liveweight is
achieved under most circumstances by thoroughly mixing 1.67 kg of the product in
each metric tonne of swine ration. The resultant medicated feed is to be fed at the
rate of 1 kg per 100 kg of bodyweight each day for seven consecutive days, as part
of the individual ration. Where medicated feed is to be fed as part of the ration, it is
recommended that the ivermectin medicated feed is fed first. After this is consumed,
any remainder of the daily feed allocation should be provided. This should be
repeated for seven consecutive days.

Alternatively, where dry feed intake can be accurately determined and all animals to
be treated have similar bodyweight, the inclusion rate can be calculated using the
previous formula to allow sole feeding of medicated feed.
RECOMMENDED TREATMENT PROGRAMME
Growing Pigs
Groups of growing pigs should be treated for seven consecutive days on transfer to
clean quarters. Where an all-in all-out system is not possible, it is recommended that
the in-feed parasite control programme should begin with treatment of all growing
pigs already in the house.
Breeding animals: Breeding animals are treated by feeding medicated feed for
seven consecutive days. At the time of initiating any parasite control programme, it is
important to treat all animals in the herd. After the initial treatment, use the premix
regularly as follows:
Sows: Treat 14-21 days prior to farrowing to minimize infection of piglets.
Gilts: Treat 14-21 days prior to breeding. Treat 14-21 days prior to farrowing.
Boars: Treat at least 2 times per year. Frequency of, and need for, treatments are
dependent upon parasite exposure.
This product should be incorporated by licensed feed manufacturers only.
The product can be incorporated in pelleted feed preconditioned with steam for up to
10 seconds at a temperature not exceeding 65
