Parasiticides

The Ceva parasiticide range, when applied strategically during the production cycle in cattle and sheep, will lower the risk of financial erosion caused by internal and external parasite infestations.

Endectocides:

Privexia® (Moxidectin): An antiparasitic remedy indicated for the treatment and control of internal and external parasites of cattle and sheep, with residual activity against certain important roundworms of cattle and sheep as well as blue ticks on cattle.

Benefits : Treatment of sheep for Wire worm during the wet season or on irrigated pastures.   Residual action against Wire worm lasts for 35 days.  Longer acting formulations (2 % Moxidectin) are not necessarily more cost-effective compared to when sheep are moved through worm infested pastures for 30-35 days after treatment with Privexia;    Longer acting formulations (2 % Moxidectin) with about 4,5 months residual action have a long “tail” (low plasma concentration) during which there is an increased risk of development of resistance.  Not recommended for routine use against sheep scab in the dry season.  Cevamec®1 %   should be used for this purpose instead during moist climatic conditions to delay the emergence of worm resistance.

Eprecis®  1% (Eprinomectin): An antiparasitic remedy indicated for the treatment and control of internal and external parasites of beef and dairy cattle, including lactating dairy cows. 

Benefits:

Dairy cattle: Only 24 hour milk withdrawal, posing no problem as colostrum does not enter the bulk tank.  Treatment with Eprecis should be around the time of calving in dairy herds on pasture where the bulk milk tank ODR reading is > 0,5 for Brown Stomach worm antibodies.  This intervention will prevent an erosion of 0,5ℓ  or more in daily milk yield per treated cow - preventing a loss of  about 150 – 300 ℓ+ per cow per lactation.

Beef cattle: Use in Autumn at the time of weaning.   It’s 28 day residual effect against Blue ticks, during which rotation through as many grazing camps as possible takes place, aids in a LONG ACTING decrease in Blue tick infestation, resulting in lower dipping costs during the ensuing summer;   

If lactating beef cows are treated in Spring in Liver fluke-free regions, the lower Eprinomectin milk residues taken in by the suckling calf will help ensure that the development of an innate resistance to Redwater can develop unhindered.

Cevamec®  1% (1% Ivermectin): A 1% Ivermectin for sheep and cattle.

Benefits:

Cattle: Roundworm, Eye worm and Parafilaria (false bruising – 70 days needed before slaughter for lesions to disappear after treatment), sucking and mange lice, as well as sand tampans.  Treats maggot infested wounds (effective for 2 weeks) and Blue ticks (21 days effective).  Fast grazing rotation for 21 days in Spring and again in Autumn will lead to a decrease in next generation blue tick numbers.

Sheep: Prevention and treatment of roundworm, nasal bot, sheep scab and Australian itch mite during moist conditions.  To minimize the development of worm resistance, do not use during the dry season.

Ceva Super (1 % m/v Ivermectin;  10 % m/v Clorsulon) A Roundworm and Adult Liver Fluke remedy for cattle.

Benefits:

With a > 90 % efficacy against adult liver fluke infestations in cattle, Ceva Super should at least be strategically administered towards the end of Winter or early Spring in order to remove egg-laying adult liver flukes.  This is the predominant stage of the life cycle at that time of the year.  Minimizing liver fluke egg contamination of open drinking water sources by adult liver flukes will result in lowering the infestation rate by immature stages during the ensuing warmer climatic conditions.  This helps to lower the incidence of severe liver damage due to migration tracts by immature liver flukes.  It is effective against the major roundworm species as well.

Anthelmintics: 

Avex® (Albendazole / Selenium) against roundworms and milk tapeworm.  Also contains Selenium.

Benefits:

Prevents pre-weaning (2-7months) loss in calf growth potential due to worms.  Contains Selenium, an important anti-oxidant necessary for disease resistance in fast growing calves. Will not interfere with the development of resistance against Redwater in suckling calves.  The low volume dose (6 mℓ/90 kg) decreases the risk of wastage.

Douvistome® (34 mg Oxyclosanide / mℓ) Oral drench of the Salicylanilyde group anthelmintics for the treatment of Liver Fluke and Gaint Liver Fluke Adult infestations as well as immature stages of Conical Fluke in Cattle.

Benefits:

Kills adult Liver Fluke and thereby aids in decreasing the contamination of pastures with fluke eggs when all cattle are treated simultaneously.  This results in a lowered infestation of fresh water snails (the intermediate host) - which lowers infestation rate of grazing cattle.

The lower dose of 100 mℓ for all animals > 350 kg livemass is convenient when compared to the conventional dose of 150 mℓ.

In Dairy cattle, following one treatment with the Liver Fluke larvicidal drug,  Triclabendazole at steam-up (about 3 weeks before anticipated calving), the Douvistome zero milk withdrawal time allows at least 3 follow-up treatments during lactation with 70 day-intervals between each treatment.  By lowering a potential loss of 0.5-2 litres erosion on daily milk yield, there is a return on investment to this approach – which also slows the rate of development of Liver Fluke resistance against Triclabendazole. 

In beef cattle Douvistome routine treatment is positioned about two months after the first frost in regions where Liverfluke is prevalent.   Two doses, 72 hours apart, will treat Conical Fluke infestations - especially in young stock which do not have immunity.

Ectoparasiticides: 

Cypertraz® Pour-on (Cypermethrin / Amitraz) against ticks, lice, mites and flies.  No milk withdrawal period.

Benefits:

After application it has approximately a 10-14 day residual effect.

For about 1 week following an application, the herd should be moved through as many grazing camps as possible to achieve a long-acting lowered risk for heavy Blue tick re-infestations.

Spot treatment (on the face, legs and tail switch) in lactating dairy cows – especially to limit the erosion caused by flies on dry matter intake and hence milk yield – will reduce the risk of a general skin irritation.

Ceva Cyperdip® 20% EC   (20% Cypermethrin)    An emulsifiable pyrethroid concentrate for use in spray races, hand held spray equipment and dip tanks.  Controls ticks, kills lice, biting and nuisance flies on cattle. 

Benefits:

As an aid to hygiene and biological control of insects it will minimize insect worry that significantly lowers pasture and total mixed ration (TMR) dry matter intake and hence impact on milk yield and growth. Can be used during insect-borne virus disease outbreaks to limit virus transmission.

Effective against all susceptible tick species.

Ceva Amitraz® 12,5%   (12,5% Amitraz)  This Amidene spray dip controls ticks and kills lice and mange mites on cattle.  For use in spray races and in hand held spray equipment.  Not to be used in plunge dip tanks.       

Benefits:

This tick detaching spray dip is ideal for intensive tick control – as frequently as weekly. It has a tick repellent action that keeps ticks away from treated cattle.

Where heavy tick infestations are experienced, this total emulsifiable concentrate with tick detaching properties is ideal.

It is not as effective against flies and midges hence Ceva Cyperdip 20 % EC is recommended for this purpose.

Anti-protazoals: 

Veriben® B12 Granules  (Diminazene/VitaminB12): Cures and prevents Asiatic and African Redwater.  The Vitamin B12 aids in the re-generation of red blood cells following treatment.

Benefits of Veriben®:

Zero milk withdrawal;  protects for 2 and 4 weeks respectively against new outbreaks of Asiatic and African Redwater.  Used for treatment of clinical cases and prevention of new cases during an outbreak.

DOES NOT sterilize the existing immunity against Redwater.

Imidox®   (Imidocarb Dipropionate 12 % m/v) For the treatment and prevention of Asiatic and African Redwater and the treatment of Anaplasmosis.

Benefits:

At the dose of 2,5 mL per 100kg body mass it treats and protects, for 4 and 8 weeks respectively, against new cases of Asiatic and African Redwater.  Ideally suited for extensive beef herds or at dry-off in pregnant dairy cattle before they are turned out onto pastures where there is a risk of tick infestation.

During a Redwater outbreak a dose of 1.0 mL per 100 kg bodymass, administered to cattle at risk which may be incubating the disease, will help prevent foetal loss in pregnant animals (due to the fever reaction) and further deaths. 

DOES NOT sterilize the existing immunity against Redwater.
