Resumo: This work was carried out to study the vertical and horizontal freezing effect on the quality of Saanen caprine breed semen. The animals were fed on 1.5kg/day coast-cross (cynodon dactylon), 0.5kg/day feed-stuff containing ground corn (70%) and soybean bran (30%), and free access to mineral supplement and water. The semen was collected through manikin once a week for 5 weeks. Variance analysis showed that the progressive motility and the survival rate were higher (P < 0.05) in the vertical freezing (31.3% and 29.01%) than in the horizontal freezing (28.0% and 26.86%) respectively. There was no influence of semen freezing methods (P < 0.05) on the spermatozoa vigor which was of 2.46 points in the vertical and 2.26 in the horizontal freezing method. It was concluded that the vertical freezing method produced the best caprine semen quality to be used in artificial insemination.

Esses animais receberam 1,5kg/dia de feno de coast-cross (Cynodon dactylon), 0,5kg/dia de ração formulada com milho triturado (70%) e farelo de soja (30%), além de livre acesso a suplemento mineral e água. A colheita do sêmen foi realizada com vagina artificial, uma vez por semana, durante 5 semanas. Ao efetuar a análise de variância, observou-se que a motilidade progressiva e o índice de sobrevivência foram melhores (P < 0,05) na congelação vertical (31,3% e 29,01%) do que na horizontal (28,00% e 26,86%), respectivamente. Não houve influência (P < 0,05) dos métodos de congelação de sêmen sobre o vigor dos espermatozóides, que foi de 2,46 pontos na congelação vertical e de 2,26 pontos na horizontal. Concluiu-se que a congelação de sêmen pelo método vertical proporcionou sêmen de melhor qualidade para a inseminação artificial.Editora da Universidade Estadual de Maringá2008-07-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/440310.4025/actascianimsci.v20i0.4403Acta Scientiarum.
