Tips on Blowfly Strike in sheep

Tips on Blowfly Strike in sheep

Fly strike (myiasis) can affect all sheep and is caused primarily by the blowfly Lucillia sericata. Once the initial strike has occurred, however, other species can escalate the problem by laying their eggs onto the site of the primary strike – this is called secondary strike. Blowfly ‘strike’ lives up to its name. In warm humid weather, significant damage can occur in as little as 36 hours. The areas most prone to strike are the withers, flanks and the tail area, particularly after scouring. Open wounds are a real attraction for flies and hence vulnerable to strike. The economic losses of fly strike can be devastating with damage affecting wool clip, leather quality and live weight gain – increasing time to market. The welfare implications are particularly serious as the effect on animals is severe. If left untreated, fly strike can quickly prove fatal.

There are two main types of product that can be used to control blowfly strike. Insecticides such as organophosphate (OP) dips and synthetic pyrethroid (SP) pour-ons are one option. Insect growth regulators (IgRs) offer a popular solution with a long duration of protection. A recent survey revealed more farmers in the UK choose IgRs than any other type of blowfly prevention.2 IgRs such as dicyclanil are available in formulation as CLiK® which offers an unrivalled 16 week protection, or as the new formulation CLiKZiN®, which offers eight weeks cover but with only a seven-day meat withhold. CLiKZiN has been launched this year and can be used where medium term protection with a short meat withhold period is required. With the meat withhold on Vetrazin® recently increased to 28 days, CLiKZiN® should give your customers the flexibility to still market lambs as needed and with the confidence that their flock is protected

Should blowfly strike occur, treatment must be prompt to minimise the discomfort caused and to prevent productivity losses, even the death of affected animals. In cases of strike, an SP pour-on, such as cypermethrin (Crovect®) can be used for treatment. Having suffered strike, it is also important to advise farmers on the need to implement on-going strike protection and the value of long-term treatment.

IgRs – BREAKING THE BLOWFLY CYCLE The efficacy of IgRs in preventing blowfly strike is based on their unique ability to break the fly lifecycle. This effectively stops the ‘fly waves’ from developing. There are three larval stages between egg and adult known as L1, L2 and L3. IgRs prevent the development of harmless L1 stages (that have no biting mouthparts) into the harmful L2 and L3 stages. It is the L2 and L3 larvae that burrow into the sheep’s skin and cause production losses and welfare problems.

Dynamite In Stock

Uniblock Dynamite Lick Buckets

Dynamite Animal Lick is a high sugar lick that increases forage intake and maximises the potential of your animal stock. This is made possible by a new patent pending process that takes the energy from 1.3 ton of molasses and put into a ton of Dynamite Animal Lick. The lick is also ideal for preventing twin lamb disease and ketosis.

How Does Dynamite Animal Lick Work?

Licking: The action of an animal licking increases the amount of saliva which naturally shields the stomach from acid produced when the rumen’s natural bacteria breaks down the sugar that has been consumed.
Sugar Content: Normally a diet of highly digestible sugars can affect your animals negatively by damaging their rumen micro population, but Dynamite Animal Lick uses a little and often approach. This approach together with the increase of saliva helps to increase the natural bacteria in the rumen which will make your animals more productive.
Increase In Natural Rumen Bacteria: The increase in natural bacteria that Dynamite Animal Lickcauses means the animal can process more food. The extra food intake will increase milk yield and meat production from your animals.
Mineral Supplements: Dynamite Animal Lick contains trace elements to ensure your animals stay healthy and productive.

Bimectin Plus at Killyless Stores

Here at Killyless Stores we like to ensure that our customers have the best options for all their farming needs. We are happy to stock Bimectin Plus at Killyless Stores. See the product description below for more information.

Bimectin Plus is an ideal choice for broad spectrum control of internal and external parasites in cattle. This 3-in-1 injection for chronic fluke, worms and lice contains the potent anthelmintics Ivermectin (10mg./ml) and Clorsulon (100mg/ml) and offers convenience, value for money and efficacy. The clorsulon component has been shown to be over 99% effective against adult fluke, making Bimectin Plus a popular choice for the UK’s cattle farmers.

Bimectin Plus is licensed for wide range of internal and external parasites including:

Liver fluke (adult) Fasciola hepatica
Ostertagia ostertagi (including inhibited larval stages)
Haemonchus placei
Trichostrongylus axei
Cooperia oncophora
Bunostomum phlebotomum
Oesophagostamum radiatum
Lungworms (adult and fourth-stage larvae)
Warbles (parasitic stages)
Mange mites (Psoroptes bovis, Sarcoptes scabiei var. bovis)
Sucking lice (Linognathus vituli, Haematopinus eurystemus, Solenopotes capillatus)
The product may also be used as an aid in the control of biting lice (Damalinia bovis) and the mange mite Chorioptes bovis, but complete elimination may not occur.

Common Parasites and Their Economic Impact

Lungworms, stomach worms and liver fluke can all have a devastating economic effect on the cattle herd. Bimectin Plus can help you to control all three parasites. Bimectin Plus contains Ivermectin and Clorsulon, two potent anthelmintics. Clorsulon is a potent flukicide, causing adult liver fluke to become unable to metabolise sugar and to die of starvation. This powerful combination allows you to control adult liver fluke, stomach worms and lungworm in one injection.
