The frequency of the
FAMACHA© correct interpretations were verified by comparing the results obtained with the PCV of each animal. The proportion of success was based on the following PCV references: FAMACHA© score 1 (F1): values ≥28%, F2: 23–27%, F3: 18–22%, F4: 13–17%, and F5: ≤12%. To evaluate the correlation between the breeds of goats and the chart reading success, the 95% confidence interval was determined by Pearson. Means and standard errors (S.E.) for the counting of eggs per gram (EPG) of faeces were calculated for dairy goats in each FAMACHA© score category. The percentage of success on the interpretation of FAMACHA© ranged from 32.6% (May 2009) to 87.5% (April 2010). It was observed a low percentage of correctness for the use of buy Ion Channel Ligand Library FAMACHA© during the first three months with 32.6, 47.3 and 68%, respectively. INK1197 The percentage reached a considerable level above 70% after the fourth month of evaluation. The quarter success mean were 49.3% (first quarter), 76% (second quarter), 83.6% (third quarter) and 76.1%
(fourth quarter). The most prevalent helminth in all larval culture was Haemonchus sp. (80.1%) followed by Trichostrongylus sp. (13.2%) and Oesophagostomum sp. (6.7%). Means and standard errors of EPG were calculated for dairy goats in each FAMACHA© score category (Table 1). There was an increase in the EPG values following the increase in the FAMACHA© score. More than half of the evaluated animals (52%) were classified as FAMACHA© score 2, with a mean of 515 EPG. The results confirm the objective of the
method in a semi-arid area of Brazil for not to deworm animals with FAMACHA© scores 1 and 2. Correlations between the variables are listed in Table 2. Although there was a good correlation between EPG and FAM there was no difference between seasons/months. PCV and FAMACHA were moderately negative correlated throughout the year as EPG and PCV. The occurrence of such finding may be related with the resilience characteristic of the breed in the region and the adjustment of the FAMACHA into goats. The factors EPG and FAMACHA and H. contortus had a much lower correlation (0.375) during the rainy season as compared to 0.707 PRKACG during the dry months. The correlation of treatment, the incidence of H. contortus, and rainfall was higher during the rainy season. The success of the evaluation rate after the first quarter (mean of 78.5%) are similar to those found by Chagas et al. (2007), who tested the FAMACHA© method in sheep herds in southeastern Brazil. We got a low success rate at the beginning of the use of the FAMACHA© method on the first quarter (mean of 55%) while in the second quarter, the success mean rose to 80%. Molento et al. (2004) attributed the low success rates at the start of the implementation due to the lack of experience of the observers in the conjunctiva colour interpretation as well as the use of the method in goats.
