Valoración de la calidad seminal en toros reproductores de 24 a 36 meses de edad de la raza charoláis de la provincia de Morona Santiago.

Abstract

This research proposed to assess the seminal quality in breeding Bulls from 24 to 36 months of age in the Charolais breed in Morona Santiago province; parameters were taken into account both macroscopic and microscopic of 8 bulls, 4 from Morona and 4 from Huamboya. In the physical analysis, they presented a very good health aspect, body valuation of 4, sexual rest of 5 days, high sexual libido. Semen collection was by a direct mount with an artificial vagina, then placed in a graduated tube with Maria bath at 37 degrees, in order to avoid thermal shock. In the macroscopic test, 5 specimens showed a slightly yellowish whitish color, 3 milky opaque inconsistency, the 5 presented a very good consistency and 3 good, the Ph between 6.5 to 6.9. The average scrotal size of 37,175 cm, 37,60 in Morona and 36,75 in Huamboya, the average seminal amount 8.8 ml, 8,75 in Morona and 7,63 for Huamboya. The spermatic concentration in Morona was 882,50*106 per ml, in Huamboya 750,00 *106 per ml, the motility mass in Morona was 3,75, in Huamboya was 3,50 over for. The progressive individual motility in Morona was 86,50% and for Huamboya 79,50%. In the viability 80% of live spermatozoa the morphological defects highlighted: acrosome, thin and lose head did not exceed 20%. These characteristics and the semen analyzed result in a high-quality genetic material for direct reproduction or artificial insemination
