New Recording 21. Results. Eye scores 43.5% - FEC 18.9% (sheep) & 14.9% - 2.2% (goats) Wide range of PCV was noted between 1 and 4 68% and 86% (sheep) & 65% and 87% (goats) would have been correctly treated Treatment recommendation greatly differed depending on eye scores.

New Recording 22. Results cont.. BCS ranged between 1-4.5 (sheep) & 1.5-4.5 (goats) Regression eq. for PCV vs BCS showed a 1 unit increase in BCS, PCV increased to 2.1%.

New Recording 24. Conclusion. Eye scores and FEC or PCV significant Sensitivity was lower and Specificity was higher Reduced numbers of animals that would have missed treatment Enforced the emphasizes that FAMACHA score should not be relied on solely for treatment decisions.
