Abstract - Suffolk, Texel, Hampshire Down and Ile de France sheep from the municipalities of Porto Amazonas, Piraquara and Araucaria in the State of Paraná, and Bagé in the State of Rio Grande do Sul were brought to Sobral, State of Ceará, to be used in a cross-breeding project. On arrival they had clinical signs of nematode parasitosis, and one Suffolk female died. The animals were treated orally with ivermectin (0.2 mg kg−1) and fifteen days later with netobimin (20.0 mg kg−1). Neither drug reduced the egg counts (measured in eggs per gram, EPG) significantly, and this suggested that the nematodes in the sheep were resistant to the anthelmintics used. Haemonchus contortus was the species involved. The egg counts were reduced after oral treatment with trichlorfon (100.0 mg kg−1). Haemonchus contortus larvae obtained from these animals before trichlorfon treatment and passaged through two nematode-free sheep were used in a further experiment.Twenty 6- to 9-month-old nematode-free lambs were infected with the H. contortus larvae (10 000 per animal) and, after the infection was confirmed, were randomly divided into four groups of five animals. Group I was orally treated with ivermectin at 0.2 mg kg−1, Group II with oral netobimin at 20.0 mg kg−1, Group III with oral trichlorfon at 100.0 mg kg−1 and Group IV was a non-treated control. Egg counts and faecal cultures were taken before dosing on the day of treatment and seven days later when all animals were necropsied and the nematodes were collected from the abomasa and counted. Drug efficacy measured by the reduction in adult H. contortus numbers was 99.9% for trichlorfon, 38.9% for netobimin and 17.6% for ivermectin. The results demonstrated the resistance of this strain of H. Contortus to ivermectin and netobimin.

Tres tipos de silos experimentais foram utilizados para se estudar a digestibilidade in vitro da materia seca (divms), carboidratos soluveis (CHO's), fraçoes fibrosas e acidos organicos (acidos lactico, propionico, acetico e butirico) das silagens de tres genotipos de girassol (V2000, M737 e Contiflor 3): 1) silo padrao com valvula tipo Bunsen; 2) silo dotado de compartimento para efluentes e sem valvula de Bunsen e 3) silo com compartimento para efluentes e valvula de Bunsen. Os tipos de silos influenciaram de forma distinta os parametros avaliados para os tres genotipos estudados. Para o M737 e o Contiflor 3 observou-se menores (P<0,05) teores de CHO's para as silagens obtidas nos silos dois e tres que continham compartimento para efluentes. Para as fracoes fibrosas foram observadas algumas diferencas estatisticas entre os tipos de silos, porem estas nao apresentaram padrao logico de variacao, o que sugere que estas fracoes nao sofreram influencia dos tipos de silos. Para os acidos organicos foram observadas diferencas entre os silos e os dotados de compartimento para efluentes apresentaram os maiores valores de acido lactico. A presenca ou ausencia da valvula de Bunsen pouco influenciou os parametros avaliados. |
