Utilização do método Famacha no diagnóstico clínico individual de haemoncose em ovinos no Sudoeste do Estado de Minas Gerais

Abstract

ResumoO objetivo deste estudo foi observar a eficácia do método Famacha no diagnóstico clínico individual de haemoncose em ovinos provenientes do Sudoeste de Minas Gerais. Cinquenta ovelhas mestiças Santa Inês foram avaliadas durante 5 meses quanto à coloração da mucosa conjuntiva (método Famacha), volume globular (VG), ovos por grama de fezes (OPG), escore corporal e alterações clínicas. O escore Famacha observado variou de 1 a 3; o escore corporal de 2 a 5; o VG de 20 a 47%; e o OPG de 0 a 7.750. As correlações entre os parâmetros avaliados, exceto Famacha com escore corporal, foram altamente significativas (P < 0,0001). O principal gênero identificado nas coproculturas foi Haemonchus (87 a 100% do total de larvas, ± 93,5%). Constatou-se redução de 87,33% na utilização de anti-helmínticos na propriedade. Conclui-se que o método Famacha, associado a outros métodos de diagnóstico, é ferramenta útil na detecção da haemoncose em ovinos.Palavras-chave: Haemonchus sp., Famacha, volume globular, OPG. AbstractThe aim of this study was to evaluate the efficacy of Famacha method in individual clinical diagnosis of haemonchosis in sheep from the south-west of Minas Gerais. Fifty crossbred Santa Inês ewes were evaluated during 5 months as for conjunctival mucous colour (Famacha method), Packed Cell Volume (PCV), Faecal Egg Counts (FEC), body score and clinic alterations. The score Famacha observed was from 1 to 3, the body score from 2 to 5, the PCV from 20 to 47%, and FEC from 0 to 7,750. The correlations between the parameters evaluated, except Famacha with body score, were highly significant (P < 0.0001). The main genus identified in the coprocultures was Haemonchus (87 -100% of total larvae, ± 93.5%). We observed reduction of 87.33% in the use of anthelmintics on the property. It was concluded that the Famacha method, associated with other diagnostic methods, is a useful tool to detect hemonchosis in sheep.

Phenotypic diversity and carcass quality of creole goats with genetic potential for resistance to infection caused by worm

“…Correlations among Famacha eye score, WEGF, BCS, and body weight are presented in Table 4. No correlation was observed between Famacha score and WEGF, whose results differed from those found by Abrão et al (2010), which were of low magnitude. Those authors stated that this occurs when nutrition plays a part in the response to gastrointestinal parasitism, and when there is parasitic load by Haemoncus contortus.…”

Impact of supplementation with different protein sources on the parasitological profile of ovine matrices and development of lambs

“…the most prevalent genus (98%) in the herd promoted an increase in the degree of anemia in the matrices. Similar responses were reported by Abrão et al (2010);Rosalinski-Moraes et al (2012) and Jiménez-Sanz et al (2016), although with stronger correlations, which reinforces the hypothesis of the presence of resilient animals in the herd. The average EPG of the matrices was 3476.0, and the animals were classified with FAMACHA © 2 and 3, and there was a sheep with 10.400 eggs/gram of feces, which was classified with FAMACHA © .…”

Situation of and phenotypic markers of susceptibility to helminth infection among sheep on farms in the Brazilian cerrado biome

“…Anthelmintic treatment was used as regular management in all flocks, on a quarterly basis (on 42.8% of the farms), an annual basis (on 28.6% of the farms), or as necessary (Abrão et al, 2010;Amarante et al, 2015), according to parasitological results and clinical symptoms (on 28.6% of the farms). On 71.4% of the farms, deworming was carried out en masse.…”

“…Because gastrointestinal parasitism is the principal cause of weight loss in sheep (Vieira, 2008), low parasite loads reflect satisfactory body conditions. In addition, the BCS has been shown to correlate positively with hematocrit and negatively with EPG (Abrão et al, 2010;Quirino et al, 2011). Maintaining satisfactory nutritional conditions is an essential measure for the prevention of helminth infection.…”
