Resumo: | Thirty two Santa Inês ewes were synchronized and bred, resulting in 18 pregnancies. These were use to inves-tigate the reliability of developmental parameters in the estimation of gestational age. The ultra-sound evaluations were carried out from day 8 to 55 of pregnancy, with day zero being the first day of breeding. For positive pregnancy diagnosis the visualization of the fetus and heart beat were considered. Gestational age was determined using: cranial-caudal length (CCC), biparietal diameter (DBP), thoracic diameter (DT), and measurements of the gestational sac. All parameters had a positive correlation with gestational age, especially DBP which was more reliable and easier to measure. In addition, growth equations were calculated to determine gestational age from the measurements. In terms of methods of carrying out the ecograph, the trans-rectal route was more practical up to 45 days after service. After this the transabdominal route was seen to be more adequate. KEY-WORDS: Age, ewe, fetal measuring, gestational. |

Tendo como objetivo principal investigar a confiabi-lidade dos parâmetros de desenvolvimento para estimativa da idade gestacional, 32 ovelhas da raça Santa Inês foram submetidas a um programa de sincronização estral e aca-saladas, resultando na gestação de 18 delas. As avaliações ultra-sonográficas foram realizadas do 8° ao 55° dia de prenhez, considerando dia zero como o primeiro dia da cobertura. Estabeleceram-se como critérios para o diag-nóstico, de prenhez, a visualização do feto e os batimentos cardíacos. Para avaliação da idade gestacional, utilizaram-se os seguintes parâmetros: o comprimento crânio-caudal (CCC), o diâmetro biparietal (DBP), o diâmetro torácico (DT), e a mensuração da vesícula gestacional. Todos os parâmetros apresentaram correlação positiva com a idade gestacional, com destaque para o DBP, tanto pela maior confiança como facilidade de avaliação. Adicionalmente, foram elaboradas equações de crescimento para determina-ção da idade gestacional a partir das medidas realizadas. Em relação à via de acesso para exame ecográfico, a transretal evidenciou maior praticidade até os 45 dias pós-serviço. A partir desse período, a transabdominal demonstrou ser mais adequada.
