| High worm challenge affects the uptake and conversion of nutrients during the critical period around lambing and lactation for ewes and limits the potential growth of lambs.
Cydectin® Long Acting Injection administered to ewes pre-lambing means cleaner pastures and reduces exposure of lambs to internal parasites.
Winter Drenching
Cydectin® Long Acting Injection is recommended for use in situations during winter when sheep (eg: Merino hoggets) are exposed to sustained high pasture contamination and continued worm challenge over an extended period of time. The need for frequent drenching is removed because of the long acting feature of Cydectin®.
Frequent monitoring is recommended in situations of high worm challenge.
Weaner/Prime Lamb Drench
Weaners and prime lambs are highly susceptible to worms. Cydectin® Long Acting Injection is an ideal drench choice for such high value stock. It offers outstanding control and long term protection necessary to maximise production.
Cydectin® Long Acting Injection can be used in a number of prime lamb production systems, they include:
- Autumn lambs produced for the heavy end of the domestic market. These lambs usually require approximately 170 to 190 days from lambing to sale.
- Winter tail end lambs usually carried over through to the following autumn.
- Late winter/spring lambs that are maintained over summer and finished in late autumn and early winter of the following year.
Do not use in lambs less than 20 kg. If considering using this product in prime lamb production, be sure to observe the withholding period and Export Slaughter Interval. (WHP for meat is 91 days and ESI is 133 days).
Barber's Pole Worm (H. contortus) Control
Under warm, moist conditions, barber's pole worm can be a significant threat to sheep of all ages.
A single dose of Cydectin® Long Acting Injection provides excellent long term protection throughout the barber's pole worm season. Egg output is reduced and pastures are cleaner for a lot longer.
Cydectin® Trial 1
Location: Armidale, NSW.
Purpose: Determine the efficacy and persistent activity of Cydectin® Long Acting Injection against barber's pole worm in sheep.
Trial Sheep and Treatment: 70 Merino sheep (male and female) aged between 12 and 14 months from a commercial flock were used in the study and randomly allocated to 2 groups. The Control group commenced the trial untreated while the Cydectin® Long Acting group received an injection in mid November. Both groups were maintained together for the duration of the trial. Sheep were predominantly exposed to barber's pole worm.
N.B: Due to a high pasture challenge during the trial, 80% of the control group (28 out of 35 animals) were salvage treated with levamisole at different times for animal welfare reasons. Of the 28 salvage treated, 8 animals had to receive a second salvage treatment
during the trial. The Cydectin® Long Acting Injection group received only one treatment on the 11th of November.
Trial summary: The control group recorded a steady increase in worm egg output reaching a peak of 2166 eggs per gram on day 98. The Cydectin® Long Acting group recorded only 52 epg on the same day and remained around this level through to day 130,
Cydectin® Long Acting Injection protects your sheep against severe challenge by barber's pole worm for up to 4 months and your pastures from contamination with eggs for not less than 107 days.
Summer Drenching
Using Cydectin LA instead of a two-summer drench program can reduce winter black scour worm burdens by ½ to almost 2/3.
"Summer treatment with Cydectin LA was very effective against Trichostrongylus vitrinus, a major winter worm problem in south-eastern Australia. The winter larval populations of this species were reduced by up to 50% compared with a two-summer drench program".
Dr John Larsen, Mackinnnon Project.
Cydectin® Trial 2b
Location: Ballarat, Victoria.
Purpose: To determine whether a single dose of Cydectin® Long Acting Injection can replace the two summer drench program.
Trial sheep and Treatment: Maiden Merino ewes.
Group 1 and 2: Represented the two summer drench strategy and were treated with Cydectin Oral Drench (Group 1) or Triton® Multiphase™ Liquid for Sheep (Group 2) on 21st December '04 and again on 15th February '05.
Group 3: Received a single treatment of Cydectin Long Acting Injection on 21st December '04.
Each group was housed on separate plots. Sheep in the
trial were predominantly exposed to small brown stomach worm and black scour worm.
Trial summary: With only one treatment of Cydectin Long Acting Injection for Sheep, Group 3 average FECs remained low at 13 epg on Day 110, and only rose to 188 epg by Day 240.
In comparison, Groups 1 & 2 received two treatments of oral drenches and recorded FECs of around 580 epg on Day 56, and 548-882 epg by day 240.
Conclusion: When used as a strategic summer drench, Cydectin Long Acting Injection gives cleaner pastures, and better protection against worms in winter than a two summer drench program
