M.  aEfeito da congelacao vertical e horizontal na qualidade do semen caprino.  c1998  aEste trabalho teve por objetivo estudar o efeito da congelacao horizontal e vertical na qualidade do semen de caprino da raca Saanen. Esses animais receberam 1,5kg/dia de feno de coast-cross (Cynodon dactylon), 0,5kg/dia de racao formulada com milho triturado (70%) e farelo de soja (30%), alem de livre acesso a suplemento mineral e agua. A colheita do semen foi realizada com vagina artificial, uma vez por semana, durante 5 semanas. Ao efetuar a analise de variancia, observou-se qua a modalidade progressiva e o indice de sobrevivencia foram melhores (P&lt0,05) na congelacao vertical (31,3% e 29,01%) do que na horizontal (28,00% e 26,86%), respectivamente. Nao houve influencia (P&lt0,05) dos metodos de congelacao de semen sobre o vigor dos espermatozoides, que foide 2,46 pontos na congelacao vertical e de 2,26 pontos na horizontal. Conclui-se que a congelacao de semen pelo metodo vertical proporcionou semen de melhor qualidade para a inseminacao artificial.   Vertical and horizontal freezing effect in caprine semen quality.  Abstract: 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&lt0.05) 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&lt0.05) 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.  aCaprino  aCongelamento  aCriopreservação  aSêmen  aCongelacao horizontal  aCongelacao vertical  aGoat1 aMORAES, G.
