ABSTRACT

One hundred twenty-three radiographs of German Shepherd dogs (47 females and 76 males) from Military Police of Minas Gerais State were studied from April 2001 to july 2004, with the purpose of establishing the frequency and asymmetry of hip displasia. The radiographs were taken with the animals in the ventrodorsal position, with the limbs parallel and the pelvis symmetric. The average age of the dogs was 33.8±23.5 months-old. The study indicated that 89.4 percent of them had hip dysplasia (91.5 percent of females and 88.2 percent of males), being 6.3 percent unilateral, 17.3 percent bilateral asymmetric, and 76.4 percent bilateral symmetric. The frequency of hip displasia in the studied population was high, indicating the necessity of an efficient control program of the disease.

ABSTRACT

Compararam-se as características físicas do ejaculado e de comportamento do garanhäo durante a coleta de sêmen, diante de uma égua em cio ou de um manequim. O manequim utilizado mostrou-se mais eficiente e seguro do que uma égua em cio, tanto para o garanhäo quanto para o veterinário. Com o uso do manequim, apenas o tempo de reaçäo do garanhäo foi maior. Entretanto, o volume de sêmen, motilidade espermática, número de espermatozóides por ejaculado e espermatozóides móveis por ejaculado foram menores com o uso do manequim, embora a concentraçäo espermática por ml fosse maior. A menor estimulaçäo sexual do garanhäo diante do manequim parece ser a causa das diferenças encontradas no comportamento e características seminais do garanhäo
