Uji Kualitas Semen Kambing Nubian dan Peranakannya (Kambing Nubian X PE) serta Kambing Boer Berdasarkan Lama Penyimpanan

The Quality of Spermatozoa of Gembrong Goats during Cryopreservation Process

“…The volume of semen of Gembrong goat found in this experiment showed a value similar to the previously reported in Ettawah crossed Goat i.e., 0.68±0.18 mL (Rizal, 2008). However, the volume of semen found in Gembrong goat in this experiment was lower as compared those reported in Nubian goat (1.50±0.50 mL) and Nubian crossed Goat (Nubian x PE) (1.33±0.29 mL) (Husin et al, 2007), in the Boer goat (0.83±0.29 mL by Husin et al, 2007 and 0.8±0.2 mL by Kostaman & Sutama, 2006), and in Saanen goat (1.13±0.37 mL) (Tambing et al, 2003). The volume of semen found in this experiment was in the normal range i.e., 0.1-1.5 mL (Jainudeen et al, 2000).…”

“…The result found in this experiment was higher than that reported by Suharyati and Hartono (2013), where the percentage of abnormal spermatozoa in Boer goat was 1.11%-2.34%. However, the result found in this experiment was lower than those reported by some previous studies, where the percentage of abnormal spermatozoa in Ettawah crossed Goat was 7.12±0.93% (Rizal et al, 2008), Kacang goat was 8.6±2.4% (Bintara, 2011), Rayini goat was 9.85±0.25% (Zamiri & Heidari, 2006), Majorera goat was 6.5±1.2% (Batista et al, 2009), and Nubian as well as Nubian crossed goats (Nubian x PE) were 12.83±0.81 and 12.34±2.77%, respectively (Husin et al, 2007). Senger (2005) reported that each fraction of semen, both obtained from cauda epididymis and ejaculate, contained abnormal spermatozoa around 5%-15% and the decreased in fertilization capability was occurred when the abnormal sperm morphology was more than 20%.…”

“…The average pH of fresh semen of Gembrong goat was 6.4. Some previous reports stated that the pH of the semen in Ettawah crossed Goat was 6.8 (Yani et al, 2001), Saanen goat was 7.13±0.24 (Tambing et al, 2003), Nubian goat was 6.67±0.76, Nubian Crossed Goat (Nubian x PE) was 6.50±0.50, and Boer goat was 6.83±0.29 (Husin et al, 2007). The range of semen pH found in this experiment was in the normal range of 5.9-7.3 that was reported in goat (Garner and Hafez, 2000).…”

“…Motilitas spermatozoa dipengaruhi oleh suhu lingkungan dan persentase spermatozoa hidup yang normal. Selama proses penyimpanan akan terjadi penurunan temperatur, sehingga akan timbul toksik pada seminal plasma dan tekanan osmotik (Husin et al, 2007).…”

“…Persentase abnormalitas meningkat dipengaruhi oleh temperatur dan keseimbangan tekanan osmotik dari proses metabolik yang berlangsung terus menerus selama penyimpanan (Husin et al, 2007). Secara umum hasil pemeriksaan rerata abnormalitas dari lima perlakuan tergolong baik karena abnormalitas spermatozoa tidak mencapai angka lebih dari 20%, meskipun berasal dari semen dengan motilitas rendah.…”
