First Drench For Lambs (Levamisole & Praziquantel) FIRST DRENCH Virbac

Description

First Drench For Lambs – Anthelmintic for the Control of Roundworms, Lungworms and Tapeworms in Lambs.

Active Ingredients: Levamisole 37.5g/L & Praziquantel 18.8g/L

First Drench For Lambs is for the treatment and control of levamisole susceptible roundworms and lungworms, including benzimidazole-resistant strains and the treatment of tapeworms in lambs.

First Drench for lambs is recommended for the control of roundworms and tapeworms concurrently.

Indications:

First Drench for lambs contains Praziquantel, a pyrazinoisoquinoline, and Levamisole, a member of the imidazothiazole (“clear”) family of chemicals. The product is effective against levamisole susceptible strains of the following types of roundworms and is effective against benzimidazole-resistant worms:

  • Barber’s pole worm – (Adult and immature) – Haemonchus contortus
  • Stomach hairworm – (Adult and immature) – Trichostrongylus axei
  • Small brown stomach worm – (Adult and immature) – Teladorsagia (Ostertagia) spp
  • Black Scour worm – (Adult and immature) – Trichostrongylus spp
  • Small intestinal worm – (Adult and immature) – Cooperia spp
  • Thin-necked intestinal worm – (Adult and immature) – Nematodirus spp
  • Intestinal threadworm – (Adult) – Strongyloides papillosus
  • Hookworm (Adult) – Bunostomum trigonocephalum
  • Nodule worm (Adult) – Oesophagostomum venulosum
  • Large bowel worm (Adult) – Oesophagostomum columbianum
  • Large-mouthed bowel worm – (Adult) – Chabertia ovina
  • Large lungworm – (Adult and immature) – Dictyocaulus filarial

Why Choose First Drench for lambs?

  1. Contains levamisole

Levamisole is a short-acting clear drench. Levamisole is still highly effective against barber’s pole worm and Nematodirus on most properties. Nematodirus is often a problem after drought or in lambing paddocks as the egg is resilient and can survive in hot, dry conditions for long periods.

  1. Contains Praziquantel

First Drench for lambs contains Praziquantel, the only chemical that controls both segments and heads of tapeworm. It makes sense to remove tapeworms to reduce the overall worm burden of your lambs, giving them the best opportunity to achieve peak performance.

  1. Broad spectrum worm control

First Drench for lambs is highly effective against levamisole-sensitive gastrointestinal roundworms and lungworms. It also provides control of tapeworms (heads and segments).

  1. Effect against barber’s pole worm

Where levamisole is still effective against barber’s pole worm, clear drenches provide a cost-effective, short-acting option to treat this worm. This is especially important if the barber’s pole worm is the major worm on a property and an alternative to a macrocyclic lactone (ML) drench is required for the purpose of rotation.

  1. Ideal for lambs

For a young lamb, life is a risky business. They’re vulnerable to cold, predators and worms. As lambs start to eat pasture, they develop a worm burden. Unlike older sheep, lambs haven’t yet built up their immunity against worms. Worm infections lead to reduced wool production and lower body weights in sheep of any age; a high worm burden will have a far bigger impact on young sheep.

  1. Short meat WHP and ESI

Only approximately 0.9% of the initial dose of levamisole can be found in the tissues. This enables First Drench for lambs to have a very short meat withholding period and export slaughter interval, giving you the flexibility to get your lambs to market at the optimal time.

When to Use First Drench for lambs?

  1. At weaning

Drenching at weaning minimises parasites’ impact on your lambs in a high-growth phase, who are undergoing nutritional stress and have little immunity to fight the worms themselves. Any setback to their growth at this stage can lead to stunting and permanent underperformance.

  1. Post-weaning

Lambs remain vulnerable for several months post-weaning. They should be monitored regularly using worm egg counts and treated if worms become a problem.

  1. Strategic treatment of adult sheep

The source of infection for lambs is, in most cases, adult sheep.  Although tapeworms are unlikely to have clinical impacts on adult sheep, strategic treatment of ewes can reduce pasture contamination and resulting infection levels in their offspring.

  1. Worm testing

Worm egg counts provide valuable information to optimise drench timing. Egg counts will show if a drench is not required because of low worm numbers but will also reveal production-limiting worm infections long before clinical signs such as scouring or wasting are evident. A larval differentiation assay provides identification of the worm species present so that the optimal type of drench can be selected.

  1. Drench resistance testing

Understanding the resistance level to the various drench families on a particular property is essential. Faecal egg count reduction tests (FECRTs) provide objective measurements of which drenches are working and which fall below the efficacy required for good worm control (i.e. minimum 95% efficacy). FECRTs should be conducted every two to three years to monitor any changes in resistance levels.
