Abstract

Penampungan semen pada kerbau seringkali menghasilkan semen yang tidak menunjukkan adanya pergerakan massa spermatozoa. Semen seperti ini disebut semen statik, sedangkan semen yang menunjukkan adanya pergerakan massa spermatozoa disebut semen motil. Penelitian dilaksanakan untuk mengevaluasi kualitas semen dan spermatozoa pada semen motil dan semen statik kerbau lumpur. Sumber semen diperoleh dari 3 ekor kerbau lumpur dengan kisaran umur 2.5 sampai 3,0 tahun dan berat badan 441 sampai 477 kg yang dipelihara di Teaching dan Experimental Farm, Fakultas Peternakan Universitas Mataram. Sebanyak sembilan puluh delapan ejakulat terdiri atas 52 ejakulat semen motil dan 46 ejakulat semen statik digunakan pada penelitian ini untuk mengevaluasi kualitas semen dan spermatozoa pada ketiga sumber semen tersebut. Kejadian ejakulat statik adalah sekitar 47 persen yang bervariasi dari pejantan ke pejantan. Penelitian menunjukkan bahwa perbedaan di antara kerbau jantan didapati tidak signifikan untuk semua karakteristik semen statik, kecuali volume semen. Ketika data karakteristik semen dari ketiga kerbau jantan disatukan, ejakulat statik menunjukkan pH, total spermatozoa abnormal dan ekor bengkok yang lebih tinggi (p<0,05) dibandingkan dengan ejakulat motil. Sebaliknya, ejakulat statik menunjukkan penurunan volume ejakulat, konsentrasi sperma dan spermatozoa hidup yang signifikan (p<0,05). Diperlukan penelitian lebih lanjut tentang kesesuaian semen motil kerbau lumpur yang dipreservasi dalam keadaan cair dan beku.

Abstract

The objectives of the present study were examined the correlation and regression of body measurements of the Doro Ncanga buffaloes in the Savanna of Mount Tambora Dompu Regency, Indonesia. A total of 339 animals were used in this study. In female, body weight (BW) was found to be significantly (p0.05) correlated with body length (BL), the degree of correlation increased from 0-6 (r=0.319) to 13-24 months (r=0.394), thereafter decreased at 36 months (r=0.160). The BW was not significantly correlated with height at wither (HW) for all 5 age groups. However, BW and heart girth (HG) were highly correlated (p0.01) between age groups 0-6 (r=0.967) and 36 months (r=0.978). The BL was significantly (p0.01) correlated with HW from 0-6 to 13-24 months of age, except for 25-36 months of age. The correlation between BL and HG was highly significant (p0.01) at 0-6 (r=0.427) and 13-24 (0.371) months of age, then decreased with the increase of age. The HW had no strong correlation with HG  at all groups. Regression model of BW changes with HG was predictable with R2 values ranged from 0.896 to 0.957. In male, BW had a strong correlations with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). The BL and HW were not highly correlated with BW at all groups. However, BW was significantly (p0.01) correlated with HG for age groups 0-6 (r=0.979) and 7-12 months (r=0.972). Their R2 values were 0.958 and 0.945, respectively. A highly significant (p0.01) correlations were also observed between BL and HW for age groups 0-6 months (r=0.677)and 7-12 months (0.462). The  R2 values were 0.458 and 0.214 for the two different age groups, respectively. The estimates of coefficient of determinations and predictive equations show that HG alone could be used to predict BW of female and male Doro Ncanga buffalo at different age groups.
