Abstract

Avaliação da ação anti-helmíntica da semente de jerimum (Curcubita pepo L.) em ovinos. The sheep industry has an extremely important economic role in Northeast Brazil. Parasites are a harmful factor in the development of the herd, which include: increased number of stillbirths in a herd, growth retardation, decreased weight gain, low fertility, decreased milk production. The wrong way of administering dewormers has led to resistance, so this work was developed in search of a good anthelmintic action that does not cause resistance themselves and that neither one is a residue in the meat. The animals were divided into two groups (Group A and Group B) of 16 animals and these animals was subdivided into 8, 8 undergoing treatment with the pumpkin seeds and 8 served as control, were considered as infected by the FEC (above 500), and subjected to treatment before three consecutive days, the amount of 40g/dia seed crushed in a blender, was performed three fecal samples, the first on day 0 before treatment, the second in seven days and finally the third on 30. The first stool examination revealed infection, the date on which the tests were started from May to June, late rainy season. In Group A are 16 sheep from a property that had to control entry and exit of animals as well as the frequency of deworming and cleaning the pens, as the 16 Group B had no control of entry and exit of animals and had no periodicity of deworming and did not even clean the corrals. The effectiveness of pumpkin seeds is demonstrated following groups: Group A, 28.26% (first sampling) and 88.77% (second test), Group B, 16.23% (first sampling) and 54.05 % (second test). In the analysis verified the presence of Trichostrongylus and Strongyloides.
