Resumo: | The effects of feeding urea on embryo production, quality and developmental stages and follicular status at the beginning of a superovulatory treatment of Toggenburg does fed urea diet were investigated in this study. Eighteen females were randomly allocated to receive diets with: no urea (control, n=8), and 2.4% urea dietary dry matter (n=10) UDM. The embryo recovery was performed at day 7 or 8 of estrus cycle by transcervical technique and classified according to quality and developmental stage. The follicular status was determined by transrectal ultrasonography at the first day of FSH injection. The number and quality of embryos were not affected by dietary urea concentration. Embryos from does treated with 2.4% UDM were recovered at advanced stage. Urea concentration (2.4%) decreases the number of follicles with less than 5 mm diameter. This follicle class is positively correlated to the number of recovered embryos and to the number and percentage of excellent and good embryos. |

Dezoito cabras da raça Toggenburg foram distribuídas equitativamente para receberem dietas: sem ureia (controle, n=8) e 2,4% de ureia na matéria seca total da dieta (n=10) UMS. Os embriões foram recuperados entre o 7º o 8º dia após o estro pela técnica transcervical e classificados pela qualidade e pelo estádio de desenvolvimento. O status folicular foi determinado por ultrassonografia transretal no dia da aplicação da primeira dose de FSH. O número e a qualidade dos embriões não foram influenciados pela concentração de ureia na dieta. Embriões em estádio avançado de desenvolvimento foram recuperados do tratamento com 2,4% de ureia. A concentração de ureia testada (2,4%) diminui o número de folículos com menos de 5 mm de diâmetro, categoria que se correlaciona positivamente ao número de embriões coletados e ao número e à porcentagem de embriões excelentes e bons.Sociedade Brasileira de Zootecnia (SBZ)2020-08-29T00:43:08Z2020-08-29T00:43:08Z2011-02info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAMORIM, L. da S. et al.
