Glyn Arthur Project Update - December 2024

What has been done to date?

  • Blood and Mineral Analysis
    • Vet visit to take blood samples from ewes and replacement ewe lambs for mineral analysis.
    • A bolus plan has been implemented based on vet recommendations to address identified deficiencies.

The main deficiencies identified from the blood and liver results are:

  1. Selenium: Some evidence of chronic deficiency, though current levels are adequate. Therefore supplementation could be beneficial, especially for ewes pre-tupping and during pregnancy.
  2. Copper: Some evidence of chronic deficiency, with low levels in some sheep. There may also be molybdenum inhibition. Supplementation of ewes pre-tupping and during pregnancy could help address this.
  3. Iodine: Low concentration in both blood and grass. Supplementation, particularly for ewes pre-tupping and during pregnancy, is likely to be beneficial. 

These three nutrients—selenium, copper, and iodine—are the main deficiencies that need attention in the flock.

  • Parasite Management
    • Continuous monitoring of worm burdens using FEC (Faecal Egg Count) testing through FECpak by Sarah at Glyn Arthur.
    • Fluke serology on replacement ewe lambs showed little or no fluke in the flock, indicating good fluke management practices.
  • Body Condition Scoring and Ram Fertility
    • Body condition scoring of ewes completed prior to tupping to ensure optimum performance.
    • Recent ram fertility tests conducted to identify fertile rams fit for breeding.
  • Grazing and Forage Management
    • Continued rotational grazing of the flock to maintain pasture quality and improve ewe nutrition.
    • Haylage and hay analysed to prepare balanced winter rations tailored to flock needs.

Next Steps

  • Monitor the effectiveness of the bolus plan and adjust as necessary.
  • Use worm and fluke monitoring data to refine parasite control strategies.
  • Incorporate forage analysis into winter feeding plans to optimise ewe and lamb performance.
  • Continue rotational grazing and assess its impact on flock productivity and pasture condition.
