Estudo comparativo de diferentes técnicas de avaliação da concentração espermática em suínos.

Abstract: A determinação precisa e acurada da concentração espermática do ejaculado suíno é importante na produção de doses inseminantes com um número determinado de espermatozóides. O objetivo do trabalho foi comparar a eficiência de algumas técnicas de mensuração da concentração espermática no sêmen e determinar equações de predição, estabelecendo uma correlação entre elas. Foram coletados 93 ejaculados que tiveram as concentrações espermáticas determinadas de forma direta (câmara de Neubauer, CN) ou indireta (espermi… Show more

“…Although consistent with the values obtained using the Neubauer chamber, the mean values obtained using the Karras spermdensimeter ® were lower than those obtained with the Neubauer chamber when measuring bovine semen (Barbosa et al, 2011). This is contrary to what has been reported in pigs, for which the spermdensimeter tended to overestimate the concentration of sperm (Vianna et al, 2004, Murgas et al, 2010. Additionally, the spectrophotometer generates statistical disagreements in sperm measurements obtained by various researchers.…”

“…Additionally, the spectrophotometer generates statistical disagreements in sperm measurements obtained by various researchers. In some cases, sperm concentrations are overestimated (Murgas et al, 2010), and in others, they are underestimated (Vianna et al, 2004). Sperm concentration overestimation can lead to inseminating doses that have a seminal concentration lower than the recommended standards, leading to reduced fertility (Vianna et al, 2004).…”
